Interface SqlRow

A row in an SqlResult.

If you set SqlStatementOptions.returnRawResult to true, SqlRow objects will be returned. Otherwise, you will get regular JavaScript objects where keys are column names and values are values in the SQL row.

Values in an SqlRow deserialized lazily. If there is an SqlColumnType.OBJECT field in the result that can't be deserialized, it is advised to set the option SqlStatementOptions.returnRawResult to false while running the query. Otherwise, since you will get a regular JSON object, values will be tried to be deserialized; and you may get a serialization error.
