Hi All, Working on some reports and wondering about a best practice. For instance, I'm working on this query to find disbursement fees attached to a loan.
Here's the query I came up with SELECT account_fees.ACCOUNT_FEE_AMNT FROM account_fees INNER JOIN fees USING (FEE_ID) INNER JOIN fee_frequency USING (FEE_ID) WHERE fee_frequency.FREQUENCY_PAYMENT_ID = 2 AND account_fees.ACCOUNT_ID = ? My question is about the fee_frequency.FREQUENCY_PAYMENT_ID. If I hard-code in the ID value, I save having to reference two tables. The other way I could do it is putting in the name (ignoring the mis-spelling of disbursement): SELECT account_fees.ACCOUNT_FEE_AMNT FROM account_fees INNER JOIN fees USING (FEE_ID) INNER JOIN fee_frequency USING (FEE_ID) INNER JOIN fee_payment ON fee_frequency.FREQUENCY_PAYMENT_ID = fee_payment.FEE_PAYMENT_ID INNER JOIN lookup_value ON fee_payment.FEE_PAYMENT_LOOKUP_ID = lookup_value.LOOKUP_ID WHERE lookup_value.LOOKUP_NAME = 'FeePayment-TimeOfDisburstment' AND account_fees.ACCOUNT_ID = ? For some reason, I keep thinking it's important to put in the longer query to get the name, because the ID might change? Is this the right approach or should I go with the ID? If it is the right approach, what's the explanation why? Thanks!
