Querying a data table...

Question

See more:

I have created a data table with a description and three checkboxes which represent selection areas..

The datatable is bound to a grid which..
the user can then place a check in the box of one of the three areas that the description fits in..

Once the user has completed the checking, I need to include that into a SQL criteria to select records based on the outcome of their selections of description..

Eg...
Description Demand(Checkbox1) Maintenance(CheckBox2) Warranty(Checkbox3)

Red yes(Checkbox1)
Blue yes(Checkbox1)
Green yes(Checkbox2)
Yellow yes(Checkbox3)

now I want to select records from another file where the description is in one of the checkbox selections

other file

Description Date Value
Red 01/01/2010 $30
Blue 02/02/2010 $45
Red 03/01/2010 $10
Green 04/02/2010 $20
Yellow 05/02/2010 $15
Green 06/01/2010 $22

Output for Demand(Checkbox1)
Red 01/01/2010 $30
Blue 02/02/2010 $45
Red 03/01/2010 $10

Output for Maintenance
Green 04/02/2010 $20
Green 06/01/2010 $22

Output for Warranty
Yellow 05/02/2010 $15

I need the SQL Statement or Statements that will allow me to create the "in" clause or the "Exists" statments..of an SQL Statment..

Thanks

Just statements; no question.

What have you already tried? How did that work out? What specific issue arose that you need help with?

I need to do this but haven't tried anything because I don't know how to include the result of the grid in another select statement..

I need the users input to find out what categories the descriptions are in ... but I don't know how to get that into a sql query...

Thanks

I know this article refers to ASP.Net, but you may find it handy: How To Loop Through And Examine Checkbox Controls In A Datagrid[^].
You should be able to find equivalent functions in the Windows Forms version of the controls. Using the results, you should be able to construct a SQL command to fetch the data specified by the user.
