MAX_RESULT_SPOOLING_MEM Query Option

Use the MAX_RESULT_SPOOLING_MEM query option to set the maximum amount of memory used when spooling query results.

If the amount of memory exceeds this value when spooling query results, all memory will most likely be spilled to disk.

The MAX_RESULT_SPOOLING_MEM query option is applicable only when query result spooling is enabled with the SPOOL_QUERY_RESULTS query option set to TRUE.

Setting the option to 0 or -1 means the memory is unbounded.

You cannot set this query option to values below -1.
