將查詢輸出到文本：參數太少，預期為1

Question

這是我的sql代碼，如果有人可以幫助我查看它，為什么它沒有響應並給出錯誤消息。 請注意，關系為​​： table1和table2通過ResetFrequency連接； table1和table3通過AccountNumber連接。

SELECT table1.EffectiveDate, table2.ResetFrequency, table3.Loan
FROM (table1 LEFT JOIN table2 ON table1.ResetFrequency = table2.ResetFrequency)
INNER JOIN table3 ON table1.AccountNumber = table3.AccountNumber
WHERE (table1.EffectiveDate) = [Enter Date: mm/dd/yyy];

Answer 1

使用以下格式：

SELECT z.EffectiveDate, z.ResetFrequency, table3.Loan
FROM (SELECT Table1.EffectiveDate, table2.ResetFrequency, table1.AccountNumber 
      FROM table1 
      LEFT JOIN table2 ON table1.ResetFrequency = table2.ResetFrequency)z
INNER JOIN table3 ON z.AccountNumber = table3.AccountNumber
WHERE (z.EffectiveDate) = [Enter Date: mm/dd/yyy];

Answer 2

只需刪除括號或括號

SELECT table1.EffectiveDate, table2.ResetFrequency, table3.Loan
FROM table1 LEFT JOIN table2 ON table1.ResetFrequency = table2.ResetFrequency
INNER JOIN table3 ON table1.AccountNumber = table3.AccountNumber
WHERE table1.EffectiveDate = mm/dd/yyy;
