Description

Got an exception:

javax.management.MBeanException: Argument's element itemNames[0] cannot be an empty string.
at org.apache.karaf.jdbc.internal.JdbcMBeanImpl.query(JdbcMBeanImpl.java:162)
at Proxy3198a962_df91_41cc_988d_5f1e4f6da538.query(Unknown Source)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

Probably because column label is empty for select DB_NAME() query (MS SQL). select DB_NAME() AS DB works fine.
