      Description

      While fetching data from ResultSet in JDBC. I got the null pointer. Details -

      java.lang.NullPointerException
      at org.apache.drill.exec.vector.accessor.AbstractSqlAccessor.getString(AbstractSqlAccessor.java:101)
      at org.apache.drill.exec.vector.accessor.BoundCheckingAccessor.getString(BoundCheckingAccessor.java:124)
      at org.apache.drill.jdbc.impl.TypeConvertingSqlAccessor.getString(TypeConvertingSqlAccessor.java:649)
      at org.apache.drill.jdbc.impl.AvaticaDrillSqlAccessor.getString(AvaticaDrillSqlAccessor.java:95)
      at net.hydromatic.avatica.AvaticaResultSet.getString(AvaticaResultSet.java:205)
      at org.apache.drill.jdbc.impl.DrillResultSetImpl.getString(DrillResultSetImpl.java:182)

      Below mentioned method is throwing null pointer becaue getObject(rowOffset) returns null for null values & null.toString() is throwing null pointer.

      @Override
      public String getString(int rowOffset) throws InvalidAccessException

      { return getObject(rowOffset).toString(); }

      It should be like:

      @Override
      public String getString(int rowOffset) throws InvalidAccessException

      { return getObject(rowOffset)==null? null:getObject(rowOffset).toString(); }
