Hi,
Thanks for the response.
I have tried passing the parameter as above. It is working fine with the parameter having integer as datatype. i want to pass text as parameter. When i am trying to pass, it is giving the error.
In the parameter tab in dataenvironment.. what datatype to be selected when it is a text parameter.
adstr,adlongstr etc are there. i have tried with all.. but not able to pass it.

hi,
i am held up with this problem.
i have two parameters one is of interger type and one is of string type.
i am able to execute with the integer type parameter but not able to execute the report with the string data type.

where a.staff_Code=? and a.salmonthyear=?

in the parameter form, i have one text box to pass staff code and combo to pass the salmonthyear which is string(varchar). i am getting error.. in the parameters tab in data environment, for salmonthyear i have define a datatype as advar and host datatype as string...
