Property Description
PrepareMethod
OPTIONAL
{StoredProc | StoredProclfParam | Direct}
Determines whether stored procedures are created on the server for
prepared statements:
● StoredProc — A stored procedure is created when the statement is
prepared and is executed when the prepared statement is executed.
● StoredProcIfParam — A stored procedure is created only if the
prepared statement contains one or multiple parameter markers. In
this case, it is created when the statement is prepared and is executed
when the prepared statement is executed. If the statement does not
contain parameter markers, a stored procedure is not created and the
statement is executed directly.
● Direct — A stored procedure is not created for the prepared
statement and the statement is executed directly. A stored procedure
might be created if parameter metadata is requested.
The default is StoredProclfParam.
Setting this property to StoredProc or StoredProclfParam can improve
performance if your application executes prepared statements multiple
times because, once created, executing a stored procedure is faster than
executing a single database query. If a prepared statement is only
executed once or is never executed, performance can decrease because
creating a stored procedure incurs more overhead on the server than
simply executing a single database query. Setting this property to Direct
should be used if your application does not execute prepared statements
multiple times.
