You didn't mention which line is throwing the error. I'm guessing this line is the issue. The code is missing "="

VB

rs.Open "Select  Name,Phoneno,Age from Test where  SN " & addEdit.Text, con, adOpenStatic, adLockReadOnly

it should be

VB

rs.Open "Select  Name,Phoneno,Age from Test where  SN = " & addEdit.Text, con, adOpenStatic, adLockReadOnly

The problem comes from the contain of addEdit that we can't know.
-----
You code is subject to SQL injection attack
SQL Injection[^]

When you don't understand what your code is doing or why it does what it does, the answer is debugger.
Use the debugger to see what your code is doing. It allow you to execute lines 1 by 1 and to inspect variables as it execute, it is an incredible learning tool.

Debugger - Wikipedia, the free encyclopedia[^]

The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
