---------------------------------------

             Summary: SqlServer - SQL Syntax error in initial table creation
                 Key: AMQ-4120
                 URL: https://issues.apache.org/jira/browse/AMQ-4120
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.7.0
         Environment: Windows Server 2008 R2, 64bit, MS SQL Server 2008 
persistence adapter.
            Reporter: Rasitha Wijesinghe
            Priority: Minor


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?
