yes it treats myvariable as a fieldname so it errors to unknown column name myvariable
I need it to treat the contents of the myvariable as the field name

Hi,

I suppose you're talking about creating sql statement in VB? Is it this you're looking for?

"select * from database where " & myvariable & " ='" & Combobox1.Text & "'"

Well I think it would be

MyCommand.Text = "select * from database where " & combobox1 & " ='" & txtSearch.Text & "'"


where MyCommand is the MySQL command object in VB.NET
