[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3004) The comment syntax /* */ fails on DB2 for z/OS

The comment syntax /* */ fails on DB2 for z/OS ----------------------------------------------- Key: HHH-3004 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3004 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.5 Environment: Hibernate version 3.2.5 DB2 for z/OS version 8.2 Reporter: Steen Klingenberg Priority: Minor if the property use_sql_comments is set to true comments with the syntax /* */ issued in Hibernate SQL statements causes DB2 to fail because the syntax is NOT supported when connecting from a Java application... Comments in SQL statements: SQL statements can include host language comments or SQL comments. Either type of comment can be specified wherever a space is valid, except within a delimiter token or between the keywords EXEC and SQL. The following rules apply to SQL comments: - The two hyphens must be on the same line, not separated by a space. - Comments cannot be continued on the next line. - Within a statement embedded in a COBOL program, the two hyphens must be preceded by a blank unless they begin a line. - In Java, SQL comments are not allowed within embedded Java expressions. For "host languages", however, comments following the syntax /* */ are allowed! Host languages include COBOL, C, Rexx... but not Java! Would it perhaps be possible to externalize the Java statements creating the comment String into the Dialect class hierarchy ? e.g. modifying (in InsertSelect): buf.append( "/* " ).append( comment ).append( " */ " ); It requires the comments to be single-lined though - at least for DB2. Otherwise it doesn't follow above rules! Having only experience from the combination Hibernate and DB2 for z/OS and no SQL embedded comments I cannot tell the benefit potential. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
