mysqli->store_result -- Transfers a result set from the last queryInhaltsverzeichnis |
Description
Procedural style:
object mysqli_store_result ( object link)</BR >
Object oriented style (method):
class mysqli {</BR >object store_result ( void )
</BR >}
Transfers the result set from the last query on the database connection represented by the link parameter to be used with the function.mysqli-data-seek function.
Anmerkung: Although it is always good practice to free the memory used by the result of a query using the function.mysqli-free-result function, when transfering large result sets using the mysqli_store_result() this becomes particularly important.
Anmerkung: mysqli_store_result() returns FALSE in case the query didn't return a result set (if the query was, for example an INSERT statement). This function also returns FALSE if the reading of the result set failed. You can check if you have got an error by checking if function.mysqli-error doesn't return an empty string, if function.mysqli-errno returns a non zero value, or if function.mysqli-field-count returns a non zero value. Also possible reason for this function returning FALSE after successfull call to function.mysqli-query can be too large result set (memory for it cannot be allocated). If function.mysqli-field-count returns a non-zero value, the statement should have produced a non-empty result set.
