maxdb_stmt_result_metadata
(PECL)maxdb_stmt_result_metadata -- Returns result set metadata from a prepared statement
Procedural style:resource maxdb_stmt_result_metadata (resource stmt)
Object oriented style (method):class stmt {
resource result_metadata (void)
}
- If a statement passed to maxdb_prepare() is one that produces a result set, maxdb_stmt_result_metadata() returns the result resource that can be used to process the meta information such as total number of fields and individual field information.
Замечание: This result set pointer can be passed as an argument to any of the field-based functions that process result set metadata, such as:
maxdb_fetch_field() maxdb_fetch_field_direct() maxdb_fetch_fields() maxdb_field_count() maxdb_field_seek() maxdb_field_tell() maxdb_free_result()
- The result set structure should be freed when you are done with it, which you can do by passing it to maxdb_free_result()
Замечание: The result set returned by maxdb_stmt_result_metadata() contains only metadata. It does not contain any row results. The rows are obtained by using the statement handle with maxdb_fetch().
- maxdb_stmt_result_metadata() returns a result resource or FALSE if an error occured.
- maxdb_prepare(), maxdb_free_result()
