将来自多个 table 的数据插入单个 table

Question

INSERT INTO MonthlyFee(StudentID, ClassTypeID, Fee, MonthID,
          [Year], IsDefaulter, FeeStatus, CreatedDate) 
SELECT StudentID, ClassTypeID FROM ClassRollNo

我想设置以下值（主要是硬编码参数）：MonthID 1、Year 2015、IsDefaulter FALSE、FeeStatus 0 和 CreatedDate GETDATE()。

Answer 1

只需按照插入 column list 的顺序在相同的 select 语句中硬编码这些值。试试这个语法

INSERT INTO MonthlyFee
            (StudentID,
             ClassTypeID,
             Fee,
             MonthID,
             [Year],
             IsDefaulter,
             FeeStatus,
             CreatedDate)
SELECT StudentID,
       ClassTypeID,
       100, -- You missed
       1,
       2015,
       'false',
       0,
       Getdate()
FROM   ClassRollNo

注意：你错过了我硬编码的费用栏

Answer 2

使用相同的查询和您描述的值：

INSERT INTO MonthlyFee(StudentID, ClassTypeID,Fee,MonthID,
      [Year],IsDefaulter,FeeStatus,CreatedDate) 
SELECT StudentID, ClassTypeID, 0, 1, 2015, 0, 0, GETDATE() FROM ClassRollNo

Answer 3

试试这个：

INSERT INTO MonthlyFee(StudentID, ClassTypeID,MonthID,
          [Year],IsDefaulter,FeeStatus,CreatedDate) 
 SELECT StudentID, ClassTypeID,1,2013,false,0,getdate() FROM ClassRollNo
