(PECL CUBRID >= 8.3.0)
cubrid_prepare — Prepare a SQL statement for execution
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.
conn_identifierConnection identifier.
prepare_stmtPrepare query.
