RMLTC0015a-MySQL: SQL error on quoted column names

[thomas-delva]

The source query uses double quotes around column names, e.g., WHERE "Lan" = 'ES'. I don't think this is correct syntax in the MySQL dialect, you should use backticks (`) instead. The mapper throws a SQL exception on this mapping.

Anyway, since the columns contain only safe characters, I propose to not use quotes at all, and go for e.g., WHERE Lan = 'ES';. This seems to work locally.
