I have a listbox select and I want when the user selects null for the empty string it produces to pull the nulls from the SQL table.
Here's what I have now. Blank strings return nothing because there are no empty fields in the table.
SELECT * FROM dbo.Table WHERE ID = " & TextBox2.Text & " and And Field1 IN (" & Msg1 & ")
How do I code that?
If statement. When your textbox is empty, have the SQL string contain "ID is null" instead of appending the textbox's value.
If (TextBox1.Text = "") Then ' use Is Null in your sql statement Else ' use the textbox text value in your sql statement End If
(Assuming you're talking about the textbox and not whatever Msg1 is.)
