Hello guys!
I have a sql query which inserts a record in a table in a MSSQL database. This table has its primary key column as autoincrement. Obviously, I don't mention about the autoincrement column while inserting data. i.e. the 'executeUpdate' query will have all the column names and values except this autoincrement column(in this case the column name is messageID and table name is tDiscussion). This code works perfectly fine at my office. It gives problem when hosted on a different server. At both sides the server running the JSP pages is TOMCAT. I will write my query below and the error under it. Please... help.
QUERY:
String query="INSERT INTO tDiscussion(parent,subject,name,email,date,message,category)"
+"VALUES ('0','"+subject+"','"+name+"','"+email+"','"+datee+"','"+message+"','"+category+"')";

ERROR:
Internal Servlet Error:
javax.servlet.ServletException: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot insert the value NULL into column 'messageID', table 'photo.photo.tDiscussion'; column does not allow nulls. INSERT fails.

I'll bet the version of the jdbc driver for the MS/SQL implementation is different on each machine.

Are you using the same database in each case, and if not, did you double-check that the primary key is really an identity column in the second database?

It is sorta covered in the JavaRanch Style Guide.
