Re: Ibatis CLOB Support

Its when I try to insert data that I get the following error. java.sql.SQLException: ORA-01704: string literal too long I am using the classes12.jar JDBC driver, Ibatis 2.2.0, and Spring 2.0 Any help on this issue would be greatly appreciated.

Re: Ibatis CLOB Support
Yikes, be careful with that thing, it's loaded. ;-) $variable$ does substitution, so should really only be used as an absolute last resort because of the SQL injection risk. Also, this statement will be sent to the database with no parameters, because they are all being substituted in. For example, if you did insert into blah (col1, col2) values ($val1$, $val2$) where val1 = 12 and val2 = '34'... The database doesn't get this: insert into blah (col1, col2) values (?, ?). It gets insert into blah (col1, col2) values (12, '34') instead. In your case, you are then trying to set parameters on it, but there are no parameter markers, so you get Invalid column index. Further, if val2 is '34;drop table blah;--', you just inserted a record, then dropped the table. When that happens in a live app, you better hope you have a recent resume. :-D Larry

Re: Ibatis CLOB Support
If you use a parameterMap, use question marks (?). If you use a parameterClass, then use hash marks (#id#, etc.). In your case, use question marks.
