oci_fetch_assoc() returns the next row from the result data as an associative array (identical to oci_fetch_array() call with OCI_ASSOC flag).
注: 本函数对 PHP NULL 值设定 NULL 字段。
Subsequent call to oci_fetch_assoc() will return next row or FALSE if there is no more rows.
注: Don't forget, that Oracle returns all field names in uppercase and associative indices in the result array will be uppercased too.
See also oci_fetch_array(), oci_fetch_object(), oci_fetch_row() and oci_fetch_all().
