I wanted to execute this query,
it works properly with all strings except one thing,
However when i set "null" to that value,it returns nothing.
But i know there are null values in table.Because i inserted them myself.
Probably you will say me use setNull method instead setString i did too but nothing changes.
it returns nothing if i dont correct the sql
string to
"select * from my_table where name is null"
Can anyboy explain me something why is that?I am trying to develop my own persistence tools but i am stucked here...
