Prepare method

Description 

Prepares or compiles the AsaCommand on the data source.

Syntax 

void Prepare( )

Implements 

IDbCommand.Prepare

Usage 

Before you call Prepare, specify the data type of each parameter in the statement to be prepared.

If you call an Execute method after calling Prepare, any parameter value that is larger than the value specified by the Size property is automatically truncated to the original specified size of the parameter, and no truncation errors are returned.

Output parameters (whether prepared or not) must have a user-specified data type.
