Folks may get confused on why such errors occur if they put regular SQLs in the /data folder. Could use some clarification (or simply a fix):

[ERROR] MainDeployer [main] [7-14 13:47:20] - This change failed: Object [mytable]; ChangeName [n/a]; Type [STATICDATA]; LogicalSchema [abc]; PhysicalSchema [abc]; File [mytable.sql] [ERROR] MainDeployer [main] [7-14 13:47:20] - From exception: java.lang.IllegalStateException: Cannot have group breaks or any breaks other than Field or DataObject - is your primary key defined correctly? com.gs.obevocomparer.compare.breaks.GroupBreak@2ee3065e at com.gs.obevo.db.impl.core.changetypes.CsvStaticDataDeployer.parseReconChanges(CsvStaticDataDeployer.java:304) at com.gs.obevo.db.impl.core.changetypes.CsvStaticDataDeployer.getStaticDataChangesForTable(CsvStaticDataDeployer.java:189) at com.gs.obevo.db.impl.core.changetypes.CsvStaticDataDeployer$1.valueOf(CsvStaticDataDeployer.java:117)
