Multiple Columns with the Same Name

Some SQL tools allow you to work with queries like this:

SELECT 'data_1' AS `column_1`, 'data_2' AS `column_1`;

This won't work in Plotalot. All columns must have unique names. In Plotalot, if two or more columns of a SQL result have the same name, the last column takes precedence and overwrites data from a previous column with the same name.
