mysqli::store_result
mysqli_store_result
Transfers a result set from the last query
Description
Object oriented style
mysqli_result mysqli::store_result
( void
)
mysqli_result mysqli_store_result
( mysqli $link
)
Parameters
-
link -
Procedural style only: A link identifier
returned by mysqli_connect or mysqli_init
Return Values
Returns a buffered result object or FALSE if an error occurred.
Note:
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 mysqli_error doesn't return an empty string, if
mysqli_errno returns a non zero value, or if
mysqli_field_count returns a non zero value.
Also possible reason for this function returning FALSE after
successful call to mysqli_query can be too large
result set (memory for it cannot be allocated). If
mysqli_field_count returns a non-zero value, the
statement should have produced a non-empty result set.
Notes
Note:
Although it is always good practice to free the memory used by the result
of a query using the mysqli_free_result function,
when transferring large result sets using the
mysqli_store_result this becomes particularly
important.
