Question

我正在尝试使用其他参数进行Insert Select查询，但它不起作用。以下是我的代码：

INSERT INTO [epmscdc].[dbo].[billing] 
([pid] ,[did] ,[lid] ,[totalamt] ,
[cash] ,[bchange] ,[btrans_date])
SELECT patientlab.did, patientlab.pid, 
       patientlab.lid, laboratory.lprice 
FROM patientlab
INNER JOIN laboratory 
  ON patientlab.lid = laboratory.lid
INNER JOIN doctor 
  ON patientlab.did = doctor.did 
WHERE patientlab.pid = 3 
  AND pstatus = '-', 1000,1000,GETDATE())

我只想从其他表格中选择特定字段，我想从文本框中获取cash，change，trans_date，以便我该怎么做？

Answer 1

INSERT INTO [epmscdc].[dbo].[billing] ([pid] ,[did] ,[lid] ,[totalamt] ,[cash] ,[bchange] ,[btrans_date])
SELECT patientlab.did, patientlab.pid, patientlab.lid, laboratory.lprice , 1000,1000,GETDATE()
FROM patientlab
INNER JOIN laboratory ON patientlab.lid = laboratory.lid
INNER JOIN doctor ON patientlab.did = doctor.did 
WHERE patientlab.pid = 3 AND pstatus = '-'

INSERT INTO ..... SELECT .....语法插入从select语句返回的结果集，不能在末尾使用逗号传递其他值。只需在select语句中选择值，整个返回的结果集就会插入到目标表中。

Answer 2

    INSERT INTO [epmscdc].[dbo].[billing] ([pid] ,[did] ,[lid] ,[totalamt] ,[cash] ,[bchange] ,[btrans_date]) VALUES
(SELECT patientlab.did, patientlab.pid, patientlab.lid, laboratory.lprice,1000,1000,GETDATE() 
            FROM patientlab
            INNER JOIN laboratory ON patientlab.lid = laboratory.lid
            INNER JOIN doctor ON patientlab.did = doctor.did 
            WHERE patientlab.pid = 3 AND pstatus = '-') As b

Answer 3

INSERT INTO [epmscdc].[dbo].[billing] ([pid] ,[did] ,[lid] ,[totalamt] ,[cash] ,[bchange] ,[btrans_date])
SELECT patientlab.did, patientlab.pid, patientlab.lid, laboratory.lprice,@totalamt,@cash,@btransDate 
FROM patientlab
INNER JOIN laboratory ON patientlab.lid = laboratory.lid
INNER JOIN doctor ON patientlab.did = doctor.did 
WHERE patientlab.pid = 3 AND pstatus = '-'

创建sqlCommand，从文本框中添加参数，然后执行。

在SQL Server中使用其他参数插入选择
