:BangHead:

Please help. I can't see why this is not working.

in Debug mode I get Cursor not initialized

B4X:

Sub Load_Click

 
Dim cursor1 As Cursor

txt= "SELECT company, name, address, city, state, zip, FROM clients WHERE company = '" & txtBox1.Text & "'"  
cursor1=SQL1.ExecQuery(txt) 
cursor1.Position=0
txtBox1.Text=cursor1.GetString("company")
txtBox2.Text=cursor1.GetString("name")
txtBox3.Text=cursor1.GetString("address")
txtBox4.Text=cursor1.GetString("city")
txtBox5.Text=cursor1.GetString("state")
txtBox6.Text=cursor1.GetString("zip")
txtBox7.Text=cursor1.GetString("email")
txtBox8.Text=cursor1.GetString("")


End Sub

Thanks in advance

Try this:

B4X:

Sub Load_Click
   Dim Cursor1 As Cursor
   'Assuming you have a company name stored in txtBox1
   txt= "SELECT company, name, address, city, state, zip, email FROM clients WHERE company = '" & txtBox1.Text & "'"  
   Cursor1=SQL1.ExecQuery(txt) 
   Cursor1.Position=0
   txtBox2.Text=Cursor1.GetString("name")
   txtBox3.Text=Cursor1.GetString("address")
   txtBox4.Text=Cursor1.GetString("city")
   txtBox5.Text=Cursor1.GetString("state")
   txtBox6.Text=Cursor1.GetString("zip")
   txtBox7.Text=Cursor1.GetString("email")
End Sub

No Luck Same Error Cursor1 not initialized debug or Release mode
Is there a updated SQL library I should be using? I have version 1.20

Is this Library for use with Microsoft SQL Server only or can also work with MYSQL?

The SQL library uses SQLITE by default. If you wish to connect to other MYSQL I believe there are routines out there, try a search of the forums.

B4X:

    Cursor1=SQL1.ExecQuery(txt)

After this line you should check for number of results before trying to retrieve the data.

B4X:

   If Cursor1.RowCount > 0 Then
