SAS/ACCESS 9.2 for Relational Databases: Reference, Fourth Edition

658 Arguments 4 Chapter 23PROMPT=ODBC-connection-informationspecifies connection options for your data source or database. Separatemultiple options with a semicolon. When connection succeeds, the completeconnection string is returned in the SYSDBMSG macro variable. PROMPT=does not immediately try to connect to the DBMS. Instead, it displays a dialogbox that contains the values that you entered in the PROMPT= connectionstring. You can edit values or enter additional values in any field before youconnect to the data source. This option is not supported on UNIX platforms.READBUFF= number-of-rowsUse this argument to improve the performance of most queries to ODBC. Bysetting the value of the READBUFF= argument in your SAS programs, youcan find the optimal number of rows for a specified query on a specified table.The default buffer size is one row per fetch. The maximum is 32,767 rows perfetch, although a practical limit for most applications is less and dependsupon on the available memory.REQUIRED=ODBC-connection-optionsspecifies connection options for your data source or database. Separatemultiple options with a semicolon. When connection succeeds, the completeconnection string is returned in the SYSDBMSG macro variable. If you donot specify enough correct connection options, a dialog box prompts you forthe connection options. REQUIRED= lets you modify only required fields inthe dialog box. This option is not supported on UNIX platforms.See your ODBC driver documentation for a list of the ODBC connection optionsthat your ODBC driver supports.These ODBC connection options are not supported on UNIX.3 BULKCOPY=3 COMPLETE=3 PROMPT=3 REQUIRED=LIBNAME-optionsdefine how SAS processes DBMS objects. Some LIBNAME options can enhanceperformance, while others determine locking or naming behavior. The followingtable describes the LIBNAME options for SAS/ACCESS Interface to ODBC, withthe applicable default values.
