Question

我想从存储过程中的文本框中传递一个字符串，用于WHERE子句，基本上我想做的就是这个。

SELECT * 
FROM TABLE 
WHERE "Textbox1.text" = '1234'

（文本框值将是列名（例如'ID'）

如何在存储过程中执行此操作？

这是我到目前为止所做的，它没有返回值

ALTER PROCEDURE ORProc
    @SEARCH_PARAMETER VARCHAR(100) = NULL,
    @OR_NUMBER VARCHAR(20) = NULL,
    @CLIENT_NAME VARCHAR(100) = NULL,
    @OR_DATE VARCHAR(10) = NULL
AS
BEGIN
    SET NOCOUNT ON;

    SELECT * 
    FROM OR_HEADER 
    WHERE '%'+ @SEARCH_PARAMETER + '%' = @OR_NUMBER 
       OR '%'+ @SEARCH_PARAMETER + '%' = @OR_DATE 
       OR '%'+ @SEARCH_PARAMETER + '%' = @CLIENT_NAME
 END;

 EXEC ORProc @SEARCH_PARAMETER = 'OR_NUMBER',
             @OR_NUMBER = '23232'

尝试下一个查询

SELECT * 
FROM OR_HEADER 
WHERE (@SEARCH_PARAMETER='OR_NUMBER' AND OR_NUMBER=@OR_NUMBER)
  OR (@SEARCH_PARAMETER='OR_DATE' AND OR_DATE=@OR_DATE)
  OR (@SEARCH_PARAMETER='CLIENT_NAME' AND CLIENT_NAME=@CLIENT_NAME)

我认为您可以将@OR_DATE VARCHAR(10) = NULL替换为@OR_DATE DATE = NULL或@OR_DATE DATETIME = NULL。

我认为您可以将三个值参数替换为一个@SEARCH_VALUE

ALTER PROCEDURE ORProc
    @SEARCH_PARAMETER VARCHAR(100) = NULL,
    @SEARCH_VALUE VARCHAR(100) = NULL
AS
BEGIN
    SET NOCOUNT ON;

    IF(ISNULL(@SEARCH_PARAMETER,'') NOT IN('','ID','OR_NUMBER','OR_DATE','CLIENT_NAME'))
    BEGIN
      PRINT 'You sent the wrong parameter!'
      RETURN
    END

    SELECT * 
    FROM OR_HEADER 
    WHERE (@SEARCH_PARAMETER='OR_NUMBER' AND OR_NUMBER=@SEARCH_VALUE)
      OR (@SEARCH_PARAMETER='OR_DATE' AND OR_DATE=CAST(@SEARCH_VALUE AS date))
      OR (@SEARCH_PARAMETER='CLIENT_NAME' AND CLIENT_NAME=@SEARCH_VALUE)
      OR (@SEARCH_PARAMETER='ID' AND ID=CAST(@SEARCH_VALUE AS int))
      OR ISNULL(@SEARCH_PARAMETER,'')=''

END
