<para>
|
|
The <function>cubrid_execute</function> function is used to execute the
|
|
given SQL statement. It executes the query by using
|
|
<parameter>conn_identifier</parameter> and SQL, and then returns the
|
|
request identifier created. It is used for simple execution of query,
|
|
where the parameter binding is not needed. In addition, the
|
|
<function>cubrid_execute</function> function is used to execute the
|
|
prepared statement by means of <function>cubrid_prepare</function> and
|
|
<function>cubrid_bind</function>. At this time, you need to specify
|
|
arguments of <parameter>request_identifier</parameter> and
|
|
<parameter>option</parameter>.
|
|
</para>
|
|
<para>
|
|
The <parameter>option</parameter> is used to determine whether to get OID
|
|
after query execution and whether to execute the query in synchronous or
|
|
asynchronous mode. CUBRID_INCLUDE_OID and CUBRID_ASYNC (or
|
|
CUBRID_EXEC_QUERY_ALL if you want to execute multiple SQL statements) can
|
|
be specified by using a bitwise OR operator. If not specified, neither of
|
|
them isselected. If the flag CUBRID_EXEC_QUERY_ALL is set, a synchronous
|
|
mode (sync_mode) is used to retrieve query results, and in such cases the
|
|
following rules are applied:
|
|
</para>
|
|
<para>
|
|
<simplelist>
|
|
<member>The return value is the result of the first query.</member>
|
|
<member>
|
|
If an error occurs in any query, the execution is processed as a
|
|
failure.
|
|
</member>
|
|
<member>
|
|
In a query composed of q1 q2 q3, if an error
|
|
occurs in q2 after q1 succeeds the execution, the result of q1 remains
|
|
valid. That is, the previous successful query executions are not rolled
|
|
back when an error occurs.
|
|
</member>
|
|
<member>
|
|
If a query is executed successfully, the result of the second query can
|
|
be obtained using <function>cubrid_next_result</function>.
|
|
</member>
|
|
</simplelist>
|
|
</para>
|
|
<para>
|
|
If the first argument is <parameter>request_identifier</parameter> to
|
|
execute the <function>cubrid_prepare</function> function, you can specify
|
|
an option, CUBRID_ASYNC only.
