MI_MEMORY_DURATION mi_switch_mem_duration(md)

		MI_MEMORY_DURATION md; 


md
is the memory duration being switched to: PER_FUNCTION or PER_COMMAND.
PER_FUNCTION causes DataBlade API to free memory automatically when a function exits, if the application did not already free the memory.
PER_COMMAND causes DataBlade API to free memory when the current SQL statement finishes executing, unless it is a cursor statement (DECLARE, OPEN, FETCH, positioned UPDATE or DELETE, CLOSE), in which case DataBlade API frees the memory when the cursor closes.
