The cubrid_prepare function is a sort of API which represents SQL statements compiled previously to a given connection handle. This pre-compiled SQL statement will be included in the cubrid_prepare.
Accordingly, you can use this statement effectively to execute several times repeatedly or to process long data. Only a single statement can be used and a parameter may put a question mark (?) to appropriate area in the SQL statement. Add a parameter when you bind a value in the VALUES clause of INSERT statement or in the WHERE clause. Note that it is allowed to bind a value to a MARK(?) by using the cubrid_bind function only.
OID return option CUBRID_INCLUDE_OID.
Request identifier, if process is successful, or false on failure.
