Hi guys, I'm struggling with an union all. I tried to union a column float with a null column:
SELECTcolumn1,column2,''AS'column 3'FROMtable a
UNION
SELECTcolumn1,column2,column3FROMtable b
If column 3 is varchar everything ok, if ( as in my case) is numeric I got an error. Any sugegstion guys? Thanks as always
