sql subquery syntax asp.net

I am trying to excute this sql query

Dim str As String = "UPDATE table1 SET " & _
            "number = '" & strc & "'," & _
            "code = '" & "123" & "'," & _
            "line= '" & dd1.text & "'," & _
            "sellr = '" & txtrun.text & "'," & _
            "endu= '" & txtex1.value+txtex2.value & "'" & _
             "WHERE number IN (select table1.number" & _
"FROM table1 INNER JOIN table2 ON table1.number = table2.number" & _
"WHERE ((table1.username)='" &  session("username") & "' AND (table1.pass)='" & session("pass") & "' AND (table2.sellnum)='" & session("sellnum") & "'));"

there is a Syntax error in query expression and this is te first time I am using nested subquery

all the field are getting String values

So if someone can tell me what is the right approach to write this query I will be very grateful

You're missing spaces after table1.number and table2.number fields in the subquery.

I don't know where you're using this query, but you might want to read about SQL injection. When you stick strings together to build SQL, your code may be vulnerable to malicious users who put SQL code into the fields of your application.
