> Priority: Trivial
>
> For table test1 (C1 varchar (10), C2 varchar (10)), when I insert a row using
> sqlContext.sql("insert into test1 values ('abc', 'def', 1)")
> I got error message
> Exception in thread "main" java.lang.RuntimeException: Relation[C1#0,C2#1]
> JDBCRelation(test1)
> requires that the query in the SELECT clause of the INSERT INTO/OVERWRITE
> statement generates the same number of columns as its schema.
> The error message is a little confusing. In my simple insert statement, it
> doesn't have a SELECT clause.
> I will change the error message to a more general one
> Exception in thread "main" java.lang.RuntimeException: Relation[C1#0,C2#1]
> JDBCRelation(test1)
> requires that the data to be inserted have the same number of columns as the
> target table.
