Syntax Description

DBMS-user-command: any DBMS command that the SAS/ACCESS engine can execute and that does not return a result set or output parameters.

Details

The initialization command that you select can be a script, stored procedure, or any DBMS SQL statement that might provide additional control over the interaction between your SAS/ACCESS interface and the DBMS.

The command executes immediately after the first DBMS connection is successfully established. If the command fails, a disconnection occurs and the libref is not assigned. You must specify the command as a single quoted string unless it is an environment variable.

DBLIBINIT= fails if either CONNECTION=UNIQUE or DEFER=YES, or if both of these LIBNAME options are specified.

When multiple LIBNAME statements share a connection, the initialization command executes only for the first LIBNAME statement, immediately after the DBMS connection is established. (Multiple LIBNAME statements that use CONNECTION=GLOBALREAD and identical values for CONNECTION_GROUP=, DBCONINIT=, DBCONTERM=, DBLIBINIT=, and DBLIBTERM= options and any DBMS connection options can share the same connection to the DBMS.)

Example: Allow Only One LIBNAME Statement to Connect

In this example, CONNECTION=GLOBALREAD is specified in both LIBNAME statements, but the DBLIBINIT commands are different. Therefore, the second LIBNAME statement fails to share the same physical connection.

libname mydblib oracle user=testuser pass=testpass
   connection=globalread dblibinit='Test';
libname mydblib2 oracle user=testuser pass=testpass
   connection=globalread dblibinit='NoTest';
