insert into text data

Our ASP program is listed below, which insert data into informix text field (c1 is char, c2 is text data type). It works but something strange when I try to query the data through isql tool. The c2 filed is "21" not "2", and I can't query the data by isql's form utility. It must use sql command select * from t1 where c1="11". <% set conn = server.createobject("adodb.connection") conn.open #dsn#, #uid#, #pwd# v_c1 = "11" v_c2 = "2" sql = "insert into t1(c1, c2)" & _ " values ('" & v_c1 & "','" & v_c2 & "')" conn.execute sql %> thanks you all!
