This article explains how to install the Microsoft ODBC Driver for SQL Server on macOS. It also includes instructions for the optional command-line tools for SQL Server (bcp and sqlcmd) and the unixODBC development headers.

The ODBC Driver for Oracle uses the ODBC interface to access data in database management systems. It allows an ODBC-compliant application to gain access to one or more data sources. ODBC drivers work under the control of an ODBC driver manager, which is a library that manages communication between the ODBC-aware application and ODBC drivers. Actual ODBC Pack (for Mac OS - compatible with MacOS 11 Big Sur) The Actual ODBC Pack installs the latest version of several Actual Technologies ODBC drivers. The included drivers and their version numbers are listed below.

This article provides commands for installing the ODBC driver from the bash shell. If you want to download the packages directly, see Download ODBC Driver for SQL Server.

Note

The Microsoft ODBC driver for SQL Server on macOS is only supported on the x64 architecture. The Apple M1 is not supported.

Microsoft ODBC 17

To install Microsoft ODBC driver 17 for SQL Server on macOS, run the following commands:

Important

If you installed the v17 msodbcsql package that was briefly available, you should remove it before installing the msodbcsql17 package. This will avoid conflicts. The msodbcsql17 package can be installed side by side with the msodbcsql v13 package.

Previous versions

The following sections provide instructions for installing previous versions of the Microsoft ODBC driver on macOS.

ODBC 13.1

Use the following commands to install the Microsoft ODBC driver 13.1 for SQL Server on OS X 10.11 (El Capitan) and macOS 10.12 (Sierra):

Driver files

The ODBC driver on macOS consists of the following components:

Resource file loading

The driver needs to load the resource file in order to function. This file is called msodbcsqlr17.rll or msodbcsqlr13.rll depending on the driver version. The location of the .rll file is relative to the location of the driver itself (so or dylib), as noted in the table above. As of version 17.1 the driver will also attempt to load the .rll from the default directory if loading from the relative path fails. The default resource file path on macOS is /usr/local/share/msodbcsql17/resources/en_US/

Troubleshooting

Some users encounter an issue when trying to connect after installing the ODBC driver and receive an error like: '[01000] [unixODBC][Driver Manager]Can't open lib 'ODBC Driver 17 for SQL Server' : file not found (0) (SQLDriverConnect)'. It may be the case that unixODBC is not configured correctly to find registered drivers. In these cases, creating a couple symbolic links can resolve the issue.

For additional cases where you are unable to make a connection to SQL Server using the ODBC driver, see the known issues article on troubleshooting connection problems.

Next steps

After installing the driver, you can try the C++ ODBC example application. For more information about developing ODBC applications, see Developing Applications.

For more information, see the ODBC driver release notes and system requirements.

Standard ODBC Architecture

ODBC data access comprises the following, four components:

Application

Most end users use ODBC-compliant applications to access their data stores.ODBC-compliant applications are executables, which issue ODBC API calls.These API calls are implemented by ODBC drivers that are customized for use with the data store. These calls enable the application to connect to the data store and query the data store via the ODBC driver.

Driver Manager

The driver manager is a library, which manages communications between applications and ODBC drivers. It responds to all ODBC connection requests made by applications, and it loads the ODBC drivers that are associated with the requests. Once the drivers are loaded, the driver manager translates applications' function calls into the corresponding ODBC API calls, and it issues these calls to the drivers. When the applications complete their requests, the driver manager terminates the connections and unloads the drivers.

Users may encounter the following driver managers on Mac client systems:

ODBC Drivers

ODBC drivers are libraries. These libraries implement ODBC API functions, which enable applications to speak to databases. Typically, applications are linked against driver managers, which load the appropriate driver libraries. However, applications may be linked directly to drivers. In this instance, driver libraries perform driver manager library functions.

Data sources

Free Odbc Driver For Mac Numbers Software

The term data source has two, distinct meanings. First, data source refers to the actual flat files, spreadsheets, or database management systems, which store data. Second, data source refers to the collection of parameters that applications use to establish connections to data stores.This data source passes a driver name, database name, server hostname, and other parameters, which are necessary to identify a database or similar storage entity.

ODBC Driver Architecture with Driver Manager

Figure 1-1 illustrates the default architecture for ODBC connectivity. The default architecture employs both a driver manager and ODBC drivers.

ODBC Driver Architecture without Driver Manager

Figure 1-2 illustrates ODBC connectivity without a driver manager component. ODBC connectivity is possible, in the absence of a driver manager, if the client application is linked directly to the ODBC driver.In some instances, a symbolic link is created, which uses a driver manager library name to point to an ODBC driver library.

OpenLink ODBC Driver Architecture

OpenLink Software provides two ODBC driver formats. Use of these drivers requires knowledge of the following items:

• Environment Variables
• Client Libraries
• Header Files
• Configuration Files
• Administrative Assistants
• Server Components

Environment Variables

Environment variables pass the locations of files and directories, which the operating system or applications need to accomplish tasks. Users do not need to set environment variables on Mac Classic and Mac OS X operating systems. Users do need to set environment variables on Darwin.

The following table lists environment variables, which must be set on Darwin clients.

Setting Environment Variables on Darwin

OpenLink's Darwin installers create openlink.sh and openlink.csh files in the root of the installation. These files contain all the environment variables, which need to be set for OpenLink client connectivity. Users must execute these files in the appropriate shell. C shell users may execute openlink.csh. Bash and Bourne shell users may execute openlink.sh.Users with different shells are encouraged to switch to C, Bash, or Bourne before executing the files.

Expert users may set and export the appropriate variables using the Darwin command line. For example:

Users may also add the variables to their .profiles to insure that the variables are set at login to their client systems.

Client Libraries

OpenLink's drivers and iODBC driver manager are library files. Users will encounter a variety of library file formats and installation locals on different, client operating systems.

The following table holds a list of common Darwin libraries. Each of these files appears in the /lib sub-directory of the OpenLink client installation. Click here to see a complete list of OpenLink libraries by platform.

Header Files

OpenLink Software provides a separate iODBC SDK product installer for Mac Classic and Mac OS X platforms. These installers contain the sql.h, sqlext.h, and sqltypes.h header files. Developers may use these files to build ODBC-compliant applications.

Configuration Files

OpenLink's Darwin-based Single-Tier drivers use the openlink.ini file to obtain database-specific environment variable settings. The openlink.ini file resides in the /bin sub-directory of Single-Tier client installations.

OpenLink's Multi-Tier brokers read the oplrqb.ini file to resolve ODBC connection requests and to enforce OpenLink's sophisticated, rule-based security. The oplrqb.ini file resides in the /bin sub-directory of OpenLink's server components installations.

Administrative Assistants

OpenLink Software produces two, graphical Administrative Assistants. The Multi-Tier Administrative Assistant is a web-based GUI, which allows users to configure all aspects of Multi-Tier connectivity. This assistant allows users to create Multi-Tier data source names, configure Multi-Tier Server components, configure rules-based security, and debug ODBC connectivity problems.

OpenLink Software also produces the independent, HTTP-based iODBC Data Sources Administrator. This web-based GUI enables users to create and administer OpenLink and non-OpenLink ODBC data source names using one, user-friendly interface.

Server Components

OpenLink's Multi-Tier drivers implement a client/server connectivity model.The Multi-Tier client comprises a driver manager and client-side ODBC driver. The Multi-Tier server component comprises a request broker and one or more database agents.

The request broker is a generic, listening process. It responds to ODBC requests made by the Multi-Tier client driver. The broker reviews these requests and spawns the appropriate database agent. The database agent is the only portion of the Multi-Tier product portfolio that is written to a specific CLI. Specifically, the database agent speaks the CLI of the database to which it is meant to connect. Hence, the agent is able to submit the SQL request to the database, retrieve its results, and convey those results to the client application.

Configuring OpenLink Data Source Names

Users must create ODBC data source names to establish connectivity between client applications and SQL data stores. ODBC data source names are collections of parameters, which enable the OpenLink driver to identify and connect to the data store. There are several means, which users may employ to create ODBC data source names.

Configuring Darwin Data Source Names

There are three methods, which users may employ to configure Darwin data source names. Expert users may configure the odbc.ini file using vi or a similar text editor. Novice users may use the HTTP-Based iODBC Data Sources Administrator, or they may use the Multi-Tier Administrative Assistant.

The odbc.ini File

The odbc.ini file appears in the /bin sub-directory of the OpenLink client installation. Users may open this file with vi or a similar text editor.The following table describes sections, which users will encounter in odbc.ini.

ODBC Data Sources

The ODBC Data Sources section lists the names of the individual data sources and pairs the names with the appropriate ODBC client driver. These data sources names are associated with formal data source specifications, which appear later in the file.

Here is the ODBC Data Sources format:

Here is a sample ODBC Data Sources section with data source names:

Data Source Specification

Each [ODBC Data Sources] data source name has a corresponding data source specification. The data source specification lists parameters, which are necessary to establish the ODBC connection. Here is the OpenLink data source specification format:

Here is a sample data source specification:

The following table explains the parameters that appear in the data source specification sections.

The following table explains additional values, which may be added to Multi-Tier data source name specifications.

OpenLink produces the HTTP-Based iODBC Data Sources Administrator for Darwin and other platforms. This Web-based administrator is a stand-alone GUI interface to the iODBC driver manager. It is similar to the Microsoft ODBC Data Sources Administrator, and it allows users to create OpenLink and non-OpenLink data source names.

Use the following instructions to create data source names with the iODBC Data Sources Administrator.

• cd into the /bin/w3config sub-directory of the client's OpenLink installation.
• Use a text editor to open the www_sv.ini file.
• Locate the [Startup] section.

PostgreSQL Single-Tier drivers recognize these specialized parameters.

Aqua GUI ODBC Administrators

Users may encounter one of three, Aqua GUI ODBC administrators on Mac OS X.Users may encounter the ODBC Administrator, the iODBC Administrator, or Data Direct's ODBC Configure. Different driver managers are installed by different OpenLink install bundles and client applications.

The ODBC Administrator ships with Apple's Jaguar installers. Users will find the ODBC Administrator's icon in their /Applications/Utilities folder.This administrator is an Apple-native interface to the iODBC dylibs driver manager. Apple dylibs are dynamic shared libraries. One copy of a .dylib or dynamic library may be shared by multiple applications simultaneously.These libraries are similar in theory to Unix dynamic libraries. However, their use and implementation are different.

The iODBC Administrator ships with OpenLink Software's driver installers.Users will find the iODBC Administrator's icon in their /Applications folder. This administrator is an OpenLink-native interface to the iODBC frameworks driver manager. Apple frameworks are special bundles or packages, which contain dynamic shared libraries, header files, documentation, and other resources that are necessary to use the library.

The ODBC Configure administrator ships with Filemaker 6. Users will find the ODBC Configure icon in /Applications/Data Direct ODBC Folder. This administrator is a Data Direct-native interface to the Data Direct's Carbon-based, CFM driver manager. Carbon is an older, Mac OS application environment and API, which Apple modified for use with Mac OS X operating systems. The CFM driver manager is based on Apple's CFM technology. CFM is an abbreviation for Code Fragment Manager. The Code Fragment Manager loads code fragments (libraries, applications, code, etc.) and prepares them for execution.

The following instructions will enable users to create OpenLink data sources using any ODBC administrator.

• Open the appropriate administrator.
• Click on the System, User, or File tab.
• Click Add.
• Select the appropriate OpenLink Single-Tier or Multi-Tier driver.
• Click Finish.
• Use the ODBC Setup dialog to provide connection parameters and to disable or enable optional features.

Figure 1-7 describes Multi-Tier parameters and options*

• Figure 1-7 - Multi-Tier Parameters & Options*

*Note:* The optional Server parameter name changes to reflect the database to which you are trying to connect. For instance, the setup routine will replace Server with Net 8 Service Name, if you choose an Oracle domain.

Developing ODBC Compliant Applications

OpenLink Software's Software Development Kits (SDK's) provide powerful tools for Apple applications developers. While Apple SDK's provide only the dylibs format driver manager, OpenLink's SDK's provide both the dylibs and frameworks format driver managers. This distinction is critical. The frameworks format driver manager provides the applications developer with versatility that is not available with dylibs.

Free Odbc Driver For Mac Numbers List

Frameworks bundles contain multiple revisions of the iODBC driver manager.Moreover, the driver manager library name points to the latest revision of the component. Therefore, developers do not need to set environment variables to point to the appropriate file. However, applications developers can choose to instantiate legacy revisions. In other words, developers can hard link applications to older driver managers to access functionality that is not present in recent revisions.

Finally, OpenLink's SDK's enable developers to build Classic, Carbon, and Cocoa native applications. Furthermore, OpenLink's SDK's assist developers who need to migrate applications from the Classic API to Carbon. And, OpenLink aids developers who need to compile applications, which run on both Classic and Mac OS X. To proceed, developers simply link their applications against OpenLink's iODBC libraries. The resulting binary issues calls to the iODBC CFM Bridge. This bridge ships with OpenLink's iODBC bundles, and it exists in Classic and OS X formats. It identifies the correct driver manager format, which to load.

OpenLink Driver Objectives

OpenLink Software's ODBC data access technologies simplify client and server computing. These technologies are based on the principle of interoperability. This principle dictates that one client application can access diverse, back-end database management systems, without knowledge of proprietary database protocols. Thereby, this powerful technology allows application developers to develop, compile, and ship applications, which speak to any, ODBC-compliant data source. The application developer does not need to cater to any specific vendor's DBMS. Moreover, application developers do not need to attend to any specific client/server architecture. The application and DBMS may reside on one or more machines.These machines may comprise similar or dissimilar operating systems and hardware.

OpenLink Software's ODBC data access technologies meet their objectives, because they are based on Microsoft's ODBC specification. The specification defines the ability to:

• Connect and disconnect to ODBC-compliant data sources.
• Retrieve SQL data from ODBC data sources.
• Obtain an ODBC driver's capabilities and characteristics.
• Obtain and manipulate ODBC driver options.
• Prepare and execute SQL statements.
• Retrieve SQL result sets and process results dynamically.
• Retrieve result metadata and process metadata dynamically

OpenLink Driver Features

OpenLink's Single-Tier and Multi-Tier Data Access Drivers provide ODBC 1.x-3.x compliance. The two driver formats also provide the following features:

Free Odbc Driver For Mac Numbers List

Single-Tier Drivers

• Blistering performance
• ODBC core, level 1, level 2, and extensions support
• Client-based scrollable cursor support
• Mac OS X client access to Microsoft SQL Server, MySQL, Oracle, PostgreSQL, and Sybase
• Support for all network protocols and server operating environments, which are supported by the database vendors' communications products.

• Note:* Single-Tier data access is dependent upon client installation of the database native communications software. For example, Oracle users require a client side installation of Net8. Progress users require a client side installation of Progress Client Networking. OpenLink's drivers for Microsoft SQL Server and Sybase are an exception. These drivers contain FreeTDS libraries, which enable OpenLink's Single-Tier drivers to speak directly to Microsoft SQL Server and Sybase databases without Microsoft SQL Server's NETLIB or Sybase's Open Client product.

Multi-Tier Drivers

• Blistering performance
• ODBC core, level 1, level 2, and extensions support
• Built-in, database-independent communications layer
• Sophisticated data encryption
• Concurrent access to heterogeneous ODBC drivers
• Intelligent metadata information handling
• Array fetching
• Network-centric result set management
• Scrollable cursor support
• Implementation of scrollable cursors across non-OpenLink ODBC drivers
• Support for all native backend functionality
• Support for distributed database capabilities of relevant backend database engines
• Implementation of all inter-process communications mechanisms supported by relevant database engines. (Sockets, Shared Memory, Pipes etc.)
• Enforcement of query optimizer configurations across all OpenLink client components
• Enforcement of database engine ISOLATION LEVELS across all OpenLink client components.
