hi i'm using a unidirect dataadapter with a select command text as follows:
Select * from bill where reference=@reference and period = @ period;
bill is a table in mysql
reference is and int tablecolumn
@reference is an int parameter
period is a date tablecolumne
@period is a date parameter
when i try it out with just account reference in the where clause it seems to work fine, but when the secon condition of the where clause(period) is added i seem to be getting the error:
invalid index -1 for this parameters.
could anybody tell me what i am missing
