    I have an access table with 157 columns and 392 rows... and several dropdownlists. How do I perform a search for all columns by using one where clause for each column? [Column1] = DropDownList1.SelectedValue (...) [Column155] = DropDownList155.SelectedValue. When I run the code I get an error saying that the query is too complex. 

    One solution I tried was to split my original datasource in two, a first for <99 columns and the second for the rest columns. However I realized I need all the info in the same gridview or table. Any ideas? Suggestions? I use VB.NET. Thanks in advance

    I don't think this is gonna work using Access. The maximum number of ANDs in a WHERE clause is 99...

    Can you use SQL Server Express? If not SQL Server Compact Edition is the way to go...

    Thanks @hans_v. First I thought of using MS Access because i'd like to modify data locally and this is easier on accdb. Are there such maximum where limitations using MSSQL? I'll give it a try. Thank you!!

    If you want to install SQL Server express/Compact and have problems with it, Start another thread in an appropiate forum...

    Do you want to install SQL Expression 2008? I think for so many columns, SQL is your choice. Have a try and hope this helps!

    Download the SQL Express at:

    https://www.microsoft.com/betaexperience/pd/SQLEXPDB32/enus/

    I think it should be installed into your PC, you mean you cannot? Can you offer us your error messages or screenshot?

    Thx again.
