Unix odbc setup

The second version of ODBC. Small reorganisation of API e. There are still a number of ODBC 2. Asynchronous connection operation, which enable applications to populate multiple connections in the pool at startup time so that subsequent connection requests can be more efficiently served.

Driver-specific C data types, which are useful for supporting new DBMS data types that existing C types do not correctly represent. Before version 3. Streamed output parameters, which enable an application to call SQLGetData with a small buffer multiple times to retrieve a large parameter value, reducing the application's memory footprint.

At run time the application provides a connection string which defines the ODBC data source it wants to connect to and this in turn defines the ODBC driver which will handle this data source. However, this is a rather simplistic description of what the driver manager does. The ODBC driver manager also:. Sometimes the ODBC driver is single tier where the driver accesses the files directly and sometimes the the driver is multi-tier where it communicates with the DBMS via another layer.

As far as the application is concerned, it is using a normal ODBC driver. A common misconception is that adding a bridge between your ODBC application and JDBC driver will introduce a lot of overhead, but you might be surprised at how quick a good gateway can be.

As far as the database is concerned, it is being accessed via the normal ODBC driver. As a result, the most flexible configuration is one where a server process is installed on the machine containing the ODBC driver, and the JDBC side of the bridge communicates with it over the network from the client side where the JDBC driver is installed. Obviously, at the Java application end, Java will already be in use, and so use of the JDBC client end driver at this side of the bridge is not a problem in fact, some bridges offer zero installation JDBC access.

However, since bit Windows was released, a new problem has arisen; you have got a bit application, which you cannot rebuild, but works on bit Windows and the bit ODBC driver is no longer available for that version of Windows or you need to write a new bit application but only have access to a bit ODBC Driver.

You can download RPMs and the source from either site and you can find the latest development release at ftp. The unixODBC source distribution is a gzipped tar file. Uncompress it and then untar the resultant file e. The principle ones you need to pay attention to are:.

If you enable the GUI components then configure will try and find QT, its libraries and header files. If you have installed QT in a single place you can provide a hint to configure by setting the environment QTDIR or --with-qt-dir to point to the top of the tree where QT is installed.

The location of this file is a configure-time variable defined with --sysconfdir but is always the file odbcinst. You can tell unixODBC to look in a different path to that which it was configured for the odbcinst. Is this page helpful? Please rate your experience Yes No. Any additional feedback? Important If you installed the v17 msodbcsql package that was briefly available, you should remove it before installing the msodbcsql17 package. Important These instructions refer to msodbcsql Submit and view feedback for This product This page.

The accompanying resource file for the driver library. This file is installed in [driver. The header file that contains all of the new definitions needed to use the driver. The install uses the standard GNU autoconf process. So its simply a matter of running. As is usual with configure, this location can be changed by altering the prefix option to configure. For a list of the operating systems supported by Snowflake clients, see Operating System Support.

To verify whether unixODBC is installed, execute the following commands:. As sudo , execute the following commands:. Verify the directory where odbcinst expects the odbcinst.

Download the package from the Snowflake Client Repository. If this occurs, run the following commands to export the GPG key, import the key into rpm , and verify the signature again:. Configure a policy for the key. The policy must be stored in the following directory:. For the policy name, you can use any text string, however the string cannot contain blank spaces.

By default, the dpkg package signature verification tool does not check the signature when you install the package. Your local environment can contain multiple GPG keys; however, for security reasons, Snowflake periodically rotates the public GPG key.
