Hello all:
I need to make certain operations like this:
select tbl_no as 'Number' , @sal1 := tbl_db - tbl_hb + @sal1 as 'Total'
I'm using the C API; so I make it through mysql_query()
Problem is than having `tbl_db' and 'tbl_hb' with certain values no
operation is carried out, and `Total' is NULL.
And what values are these that cause pproblems? Any field with a NULL value will result in a NULL total.
What am I doing bad ?
Please, help me
Thanks all
