The <function>cubrid_prepare</function> 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 <function>cubrid_prepare</function>.
|
|
</para>
|
|
<para>
|
|
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 <function>cubrid_bind</function> function only.
