What I do (using VB also)
dim SQL as string
dim sTemp as string //variable declaration in vb
sTemp="rajesh"
can i use
SQL = "select * from employee where employee.firstname='" & sTemp & "'
then execute the SQL variable, since it contains the sql statement

hi marie,
i tried the way u suggested but even then it works only if the sTemp variable is a const
like
const sTemp="rajesh"
dim sql as tring
sql="select * from Employee where ename ='"& sTemp &"'"
if i try doing
const sTemp=txtEname.txt
and then
dim sql as tring
sql="select * from Employee where ename ='"& sTemp &"'"
and do
connection.execute sql
it doesnt work
it says it needs constant expressionn in
const sTemp=txtename.txt
____________ (error)
