# [DRILL-7887](https://issues.apache.org/jira/browse/DRILL-7887): JDBC
plugin returns incorrect precision for SUM(DECIMAL) queries
## Description
Made changes to return DRILL_REL_DATATYPE_SYSTEM.getMaxNumericScale() and
DRILL_REL_DATATYPE_SYSTEM.getMaxNumericPrecision() for the case when JDBC
calculated presision is greater to avoid errors in Drill.
Also, added a check for actual value scale and precision to avoid returning
incorrect values.
## Documentation
NA
## Testing
Added unit test to check the desired behavior.
