邏輯特定計數

Question

我要填寫一個ASP：GridView控件與查詢的結果。我的查詢，有如果「san_proposta.credenciada_id」列在anothers行價值10等於計數特定STATUS_ID的ocurrences數量IF「san_proposta.credenciada_id」的列值10的不同，我需要算具有「credenciada_id」特定STATUS_ID的所有ocurrences等於10

我想後續的代碼，但我不知道該怎麼做這個細節計數。

SELECT DISTINCT San_Proposta.Imovel_Id, San_Logradouro.Descricao, San_Endereco.Logradouro, San_Imovel.Numero, San_TipoComplemento.Descricao AS Expr1, 
San_Imovel.Complemento, San_Imovel.TipoDsc1, San_Transacao.TransacaoSigla, San_Credenciada.Apelido, San_Transacao.Transacao_ID, COUNT(San_Proposta.StatusProposta_Id) AS NumeroProposta 
FROM San_Proposta 
JOIN San_Imovel 
ON San_Proposta.Imovel_Id = San_Imovel.Imovel_Id 
JOIN San_Endereco 
ON San_Imovel.Endereco_Id = San_Endereco.Endereco_Id 
JOIN San_Logradouro 
ON San_Endereco.Logradouro_Id = San_Logradouro.Logradouro_Id 
JOIN San_TipoComplemento 
ON San_Imovel.TipoComplemento_Id = San_TipoComplemento.TipoComplemento_Id 
JOIN San_Transacao 
ON San_Imovel.Transacao_ID = San_Transacao.Transacao_ID 
JOIN San_Credenciada 
ON San_Imovel.Credenciada_Id = San_Credenciada.Credenciada_Id 
WHERE (San_Imovel.Credenciada_Id = 10 OR San_Proposta.Credenciada_Id = 10) 
GROUP BY San_Proposta.Imovel_Id, San_Logradouro.Descricao, San_Endereco.Logradouro, San_Imovel.Numero, 
San_TipoComplemento.Descricao, San_Imovel.Complemento, San_Imovel.TipoDsc1, San_Transacao.TransacaoSigla, 
San_Credenciada.Apelido, San_Transacao.Transacao_ID, San_Proposta.StatusProposta_Id, 
San_Proposta.Credenciada_Id, San_Imovel.Credenciada_Id 
ORDER BY San_Proposta.Imovel_Id DESC 

Answer 1

根據你說的話（如果我正確地解釋你），它看起來像

COUNT(CASE WHEN San_Proposta.credenciada_id = 10 THEN San_Proposta.StatusProposta_Id ELSE NULL END) 

會爲你的工作數量。
