[jira] [Commented] (AMQ-4120) SqlServer - SQL Syntax error in initial table creation

["Ajoy Bhatia (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMQ-4120?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16960444#comment-16960444 ] 

Ajoy Bhatia commented on AMQ-4120:
----------------------------------

Surprised that this issue still exists in 5.15.9, even after so many years. As Tim asked, will this affect function or performance? In our case, ActiveMQ takes about 3 to 4 minutes to establish connections during server start-up. Could it be related to this?

> When using SQL Server as the backing data store and creating the AMQ tables for the very first time, the following error is logged:
> INFO   | jvm 1    | 2012/10/19 11:12:03 |  WARN | Could not create JDBC tables; they could already exist. Failure was: ALTER TABLE ACTIVEMQ_ACKS DROP PRIMARY KEY Message: Incorrect syntax near the keyword 'PRIMARY'. SQLState: S1000 Vendor code: 156
> INFO   | jvm 1    | 2012/10/19 11:12:03 |  WARN | Failure details: Incorrect syntax near the keyword 'PRIMARY'.
> INFO   | jvm 1    | 2012/10/19 11:12:03 | java.sql.SQLException: Incorrect syntax near the keyword 'PRIMARY'.
> Since there is no specific adapter for SQL Server it uses the DefaultJDBCAdapter which has getDropAckPKAlterStatementEnd() returning "DROP PRIMARY KEY".
> Not sure if this is an issue with other databases as well.
> (Note: If you already have the tables, this error is still present but only logs a DEBUG entry).
> Does it make sense to add a MSSqlJDBCAdapter that overrides getDropAckPKAlterStatementEnd?
