[Haskell-cafe] Haskell SQL backends: How is data handed over?

[Anthony Clayden]

Is that indeed so?

Hi Olaf, that's the usual format for any HLL to pass statements (queries or
updates) to SQL.

Most HLLs provide some sort of modulate/demodulate so your program doesn't
see the raw numbers-as-strings, but the parsing is going on in the
background.

Going via CSV isn't really saving anything: the "bulk insert" is again
parsing those commas and the bits in between. (A dedicated SQL engine is
probably more efficient than Haskell's string handling.)
