DBCONDITION=SQL-query-clause
|
-
SQL-query-clause
-
is a data source-specific SQL query clause,
such as WHERE, GROUP BY, HAVING, or ORDER BY.
This option enables you to specify selection
criteria in the form of data source-specific SQL query clauses, which the SAS/ACCESS engine
passes directly to the data source for processing. When selection criteria
are passed directly to the data source for processing, performance is often
enhanced. The data source checks the criteria for syntax errors when it receives
the SQL query.
The option is ignored when you use
DBCONDITION.
