Re: [hibernate-dev] Dialect support for SQL comments.

Hi, I have recently tried turning on SQL comments in hibernate 3.2.6.ga. However, I found that our database (informix 7.31) did not support SQL where the comment was at the start of the comment. Instead, the comment needed to be after the SQL. For example: /* not accepted by informix 7.31*/ select * from systables; select * from systables /* accepted by informix 7.31*/ Because of this, I have added a method to the Dialect for adding comments: /** * Add a comment to the SQL string. * * @param sql StringBuffer holding the SQL. * @param comment Comment to add to the SQL. May be null. */ public void addCommentToSql(StringBuffer sql, String comment) { if (StringHelper.isNotEmpty(comment)) sql.insert(0, "/* " + comment + " */ "); } Thus, the default implementation provides the same functionality as before. However, derived Dialects may override this method to add the comment in a different location. It is also possible to add additional comments in the derived Dialect. In our case, we also add the Java thread ID. I have included a complete patch for this change for hibernate 3.2.6.GA. Please consider its inclusion in Hibernate. Thanks, Daniel. ------------------------------------------------------------------------ _______________________________________________ hibernate-dev mailing list hibernate-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
