I am trying to use a session that I have made in JSP in a sql statement. But having difficulties.

I captured it already and this is the SQL statement I made, but doesnt work.

String mysql="select * from table1 where cottCode="<%= session.getAttribute( "theName" ) %>"";

Any help appreciated, thank you.

    I think here you are trying to do things like this:

    <%
    String name = session.getAttribute( "theName" );
    String mysql = "select * from table1 where cottCode=" + name;
    // then connecting MySql server using driver in JSP to execute the SQL query
%>

    This kind of code is called JSP Scriptlet.

    However, expressions like :

    <%= session.getAttribute( "theName" ) %>

    are called JSP Expressions.They are used to “insert the value of a scripting language expression, converted into a string, into the data stream returned to the client. ” Like this:

    <html>
    <body>
        <p>hi, my name is <%= session.getAttribute( "theName" ) %>
        </p>
    </body>
</html>

    So I don’t think you can use the expression in the middle of scriptlet. Here is the tutorial on related topics, hope it’ll help:
