Olá,
Alguém sabe dizer porque essa "query" não funciona, ou sabe
de alguma maneira melhor de fazer update com select.
UPDATE tbContas AS CA SET
Debitos = (CASE WHEN ContaID = sq.ContaDebID THEN Debitos + sq.Valor ELSE
Debitos END),
Creditos = (CASE WHEN ContaID = sq.ContaCrdID THEN Creditos + sq.Valor ELSE
Creditos END)
FROM (
SELECT L.ContaDebID,
L.ContaCrdID,
L.Valor
FROM tbLancamentos AS L
INNER JOIN tbContas AS CA1 ON CA1.ContaID = L.ContaDebID
INNER JOIN tbContas AS CA2 ON CA2.ContaID = L.ContaCrdID
) AS sq
WHERE (CA.ContaID = sq.ContaDebID OR CA.ContaID = sq.ContaCrdID)
Obrigado.
