- //=====================================================================
- // Function:
- // SQLBind();
- //
- // Description:
- // This example shows how to use Parameter Binding with Query's.
- // Parameter binding allows you to re-execute a SQL query with
- // different parameters without having to prepare the query
- // (which is done by calling DbiQPrepareExt) over and over....
- // This can result in dramatic speed improvements.
- //
- // This sample shows two examples which search for values in a
- // table:
- // Example 1: The table has been opened. The table's
- // field description structure and record buffer are
- // used to define the parameter values for DbiQSetParams().
- // This method is useful if the parameters in the SQL
- // query exactly match the field descriptions for the
- // table, as is often found in Inserts and updates. This
- // example inserts records into the table
- //
- // Example 2: The table has been opened. The table's
- // field description structure and record buffer are
- // used to define the parameter values for DbiQSetParams().
- // This method is useful if the parameters in the SQL
- // query exactly match the field descriptions for the
- // table, as is often found in Inserts and updates. This
- // example retreives records matching a certain criterion.
- //
- // Example 3: The table has not been opened. The client
- // builds the logical field description structure and record
- // buffer used to define the parameter values for
- // DbiQSetParams().
- //
- // WARNING: This example requires write access to the database.
