Teradata examples are available.Here are the SQL pass-through facility specifics for the Teradata interface.3 The dbms-name is TERADATA.3 The CONNECT statement is required.3 The Teradata interface can connect to multiple Teradata servers and to multipleTeradata databases. However, if you use multiple simultaneous connections, youmust use an alias argument to identify each connection.3 The CONNECT statement database-connection-arguments are identical to theLIBNAME connection options.The MODE= LIBNAME option is available with the CONNECT statement. Bydefault, SAS/ACCESS opens Teradata connections in ANSI mode. In contrast,most Teradata tools, such as BTEQ, run in Teradata mode. If you specifyMODE=TERADATA, Pass-Through connections open in Teradata mode, forcingTeradata mode rules for all SQL requests that are passed to the Teradata DBMS.For example, MODE= impacts transaction behavior and case sensitivity. See yourTeradata SQL reference documentation for a complete discussion of ANSI versusTeradata mode.3 By default, SAS/ACCESS opens Teradata in ANSI mode. You must therefore useone of these techniques when you write PROC SQL steps that use the SQLpass-through facility.3 Specify an explicit COMMIT statement to close a transaction. You must alsospecify an explicit COMMIT statement after any Data Definition Language(DDL) statement. The examples below demonstrate these rules. For furtherinformation about ANSI mode and DDL statements, see your Teradata SQLreference documentation.3 Specify MODE=TERADATA in your CONNECT statement. WhenMODE=TERADATA, you do not specify explicit COMMIT statements asdescribed above. When MODE=TERADATA, data processing is not case
