unixODBC - Man Page

An ODBC implementation for Unix


ODBC is an open specification providing application developers with a predictable API with which to access data sources. Data sources include SQL servers and any data source with an ODBC driver.

The unixODBC project goals are to develop and promote unixODBC as the definitive standard for ODBC on non-Windows platforms.

The HTML-formatted "Administrator Manual" shipped with unixODBC provides additional details on configuration and usage to supplement these man pages.

Environment Variables


Sets the full path to the directory containing the unixODBC configuration files. By default, this is '/etc'.


Sets the name of the unixODBC driver configuration file. The file name is relative to ODBCSYSINI and is set by default to 'odbcinst.ini'.


Sets the full path to the system-wide unixODBC configuration file containing Data Source Names (DSNs). By default, this is set to '/etc/odbc.ini'.


Sets the library name for the UI. The final name that is searched for is evaluated as "lib$ODBCINSTUI". By default, this variable is set to 'odbcinstQ4', so the resulting library name is 'libodbcinstQ4'.


Sets the configuration mode and determines where to look for configuration files. This variable must be set to one of ODBC_SYSTEM_DSN, ODBC_USER_DSN or ODBC_BOTH_DSN, which is the default value.
