cannot free memory after reading data from DB

[patres]

Hi guys,

 

i have a problem with full a memory after reading data from database. You can see a sql select brom DB, it is very simply select from dateStart to dateTo.

 

I was trying use "Request Deallocation" but every time when i am reading data from a mounth or more my RAM memory is full-used and never deallocated. 
Memory cam be deallocated when i quit from Labview.

 

Thanks for helping
