It's always difficult when you want search in database using multiple words. That means we have textbox like "google" and you Enter Some words in textbox then click "go" ,at that time you want to search all the words in textbox. This is really simple code for searching all tables that use VB.NET code and SQL server.
For who wants to search in the database must know about text split in vb. you can do it in two ways:
1. Declare Stored Procedure in SQL then set parameters in VB then split textbox with split function.
2. Declare function and SQL string without Stored Procedure then search in database with textbox and split function.
Using the code
Here blow I first declare array with two parameters then I split the textbox with "split" function. If you using Stored Procedure you can declare parameter such as "Name" the in the Stored procedure declare SQL command.
Here is the code:
Dim objparameter As New SqlParameter("@Name", SqlDbType.NVarChar, 50)
Dim a(2) As String
Dim j As Integer
a = txtsearch.Text.Split("", 2)
objparameter.Direction = ParameterDirection.Input
For j = 0 To a.GetUpperBound(0)
objparameter.Value = a(j)
//here is stored Procedure code
CREATE PROCEDURE main
select tables from computer where .... like "%"+@Name+"%"
