Hi Tiger Use OR clause like below string dbquery = select * from TBL_ERP_DAILY_INV_BATCH_REPORT where type = ' + ListValue1 + ' or [SUPPLIER NUM] = ' + ListValue2 + ' ; Hope this helps

Hi Ankit i am thinking something like as below:- string dbQuery = select * from TBL_ERP_DAILY_INV_BATCH_REPORT where type IN ' + ListValue1 + ' OR [SUPPLIER NUM] IN ' + ListValue2 + '; how to pass multiple values in single variable thats why we are using listbox. can we do like this if not then what should be the way to do that ? Thanks in advance !!

what do you mean by multiple value in listbox. as per my understandingeach list box will contain one string value only.similarly each column in table contains single value only. in this case below query shpould work.

Hi Ankit  will it work for multiple values in list item. can we put instead = where Type in string dbquery = select * from TBL_ERP_DAILY_INV_BATCH_REPORT where type = ' + ListValue1 + ' or [SUPPLIER NUM] = ' + ListValue2 + ' ;
