<para>
|
||
Функция <function>cubrid_bind</function> используется для привязки значений к указанным
|
||
меткам, либо знакам вопроса, в SQL-запросе, заданном <function>cubrid_prepare</function>.
|
||
Если не задан параметр <parameter>bind_value_type</parameter>, то будет использоваться
|
||
строковый тип.
|
||
</para>
|
||
<note>
|
||
<para>
|
||
Если привязываемые данные имеют тип BLOB/CLOB, CUBRID попытается использовать их
|
||
как потоки PHP. Если фактическое привязываемое значение не является потоком, то
|
||
CUBRID конвертирует его в строку и будет считать полным путём к файлу, где эти
|
||
данные лежат.
|
||
</para>
|
||
<para>
|
||
Если тип данных, которые будут связаны явно является ENUM, то параметр <parameter>bind_value</parameter>
|
||
должен быть элементом ENUM заданным в виде строки.
|
||
</para>
|
||
<para>
|
||
В окружении сегмента CUBRID, <parameter>bind_value_type</parameter> должен быть включён в функцию
|
||
<function>cubrid_bind</function>.
|
||
</para>
|
||
</note>
|
||
<para>
|
||
В следующей таблице приведены типы замещающих значений.
