Name
Command.Prepared Property — (Versions 2.0, 2.1, 2.5, 2.6)
Synopsis
command.Prepared = Boolean
The Prepared property indicates whether a prepared statement should be created by the current Command object before it is executed.
Datatype
Boolean
Description
If the value of the Prepared property is set to
True, then before the first execution of a query
defined by the CommandText property of the Command object, the query
is compiled and saved. From then on the Execute statement will refer
to the compiled version of the query to perform. This may slow the
initial call to Execute, but all calls that follow will benefit from
this.
If the value of the Prepared property is set to
False, then the query is never compiled; instead
the query is done directly from the Command object.
Note
Not all providers support the Prepared property. Some providers raise
an error as soon as the Prepared property is set to
True, while others do not raise an error and
simply replace the Prepared property’s value with
False.
