[Haskell-cafe] Haskell EDSL to generate SQL?

Hi, I tried to solve some large data processing solely in Haskell so I could avoid lots of eventually very long and complex SQL statements. Unfortunately, as was to be expected, that approach doesn't scale. So I do need an SQL backend. But I hope to be able to use an DSL from which I can automatically generate SQL-Strings instead of writing the SQL statements literally. Has anyone else taken a similar approach? Günther
