## Recommended Posts

Calculo financeiro

tenho duas tabelas com

valores recebidos e pagos a clientes....

Quero saber como posso ver quais sao os 10 melhores que mais lucro dão

Como posso fazer se tiver apenas valores recebidos de um determinado cliente

coluna recebido

a,20

a,15

b,30

coluna pagamento

b, 30

output seria algo

a ,35

b, 0

Para os 10 com maior lucro fazes um "select top 10 sum(coluna) ...".

Para a segunda, fazes um left join entre as tabelas.

```10 REM Generation 48K!
20 INPUT "URL:", A\$
30 IF A\$(1 TO 4) = "HTTP" THEN PRINT "400 Bad Request": GOTO 50
40 PRINT "404 Not Found"
50 PRINT "./M6 @ Portugal a Programar."```

isso ja tenho

Então tens de explicar de forma mais clara os erros ou as dúvidas que tens.

30 IF A\$(1 TO 4) = "HTTP" THEN PRINT "400 Bad Request": GOTO 50
