Description

git.commit.id.abbrev=f1b59ed

Data :

{
    "int_col":1
},
{
    "int_col":2
}

The error message from running the below query does not indicate where the problem is. Since some of the publicly found JSON's use a COMMA to separate records, we should throw a proper error message

select count(*) from `temp.json`;
