OdbcExecute Function

Action

Executes a SQL statement associated with a cursor.

Before calling this function, you have to prepare the SQL statement using the OdbcPprepare function. Array binding can be used to process multiple rows of data in a single execute operation. If the SQL statement contains place holders, it is necessary to call the OdbcBind function for each place holder first.
