SQLCODE = -204，SQLSTATE = 42704仅在本地开发服务器上

Question

since today I am getting this weird SQL error on my local development Server. The Integration Test machine is fine even if I deploy the same artifacts on both.

I know this question has been asked before, but none of the answers seemed to solve my problem so far. I already tried to switch from the myBatis ${variable} to #{variable} and back. And I also tried putting all the table names in doublequotes.

Here is the error I get for every query I send to my local applicationserver (JBoss 6.1):

### Error querying database.  Cause: com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=SCHEME.TABLENAME DRIVER=3.63.75
### The error may exist in path/to/dao/mapper/DAOMapper.xml
### The error may involve path.to.dao.mapper.DAOMapper.daoMethod - inline
### The error occurred while setting parameters
### SQL: SELECT     VAL1 as VAL1,    VAL2 as VAL2, FROM SCHEME.TABLENAME  WHERE    VAR1=     (     select       MAX (VAR1)     FROM   SCHEME.TABLENAME    WHERE      VAR2 <= VAR2 )    WITH UR;

Any Ideas?

Case closed! As I was writing my comment, saying the two environements use the same database, I thought "Maybe not".

Turns out the datasource was configured wrong in the standalone.xml

I still have no idea how that happened though.
