Question

出于某种原因，我不断收到错误'单词'DECLARE''附近的语法不正确。我应该在哪里声明我的变量，以便它不会抛出错误？我无法解决这个问题，因为我没有找到使用'WITH AS'语句并尝试声明变量的人。

CREATE PROCEDURE qryKeysValues(@KeyValue varchar(5))
    AS
    BEGIN
    WITH tbl1 AS    
        (SELECT * FROM FN_qryMethods())

    DECLARE @SQL varchar(1500)
    SET @SQL = 'SELECT ' + @KeyValue+ ' AS fldCode, tbl' +@KeyValue+ 'Key.fldID, tbl1.fldID
               FROM tbl' + @KeyValue + 'Key', tbl1
        EXEC(@SQL)
    END;

Answer 1

也许这样的东西就是你要找的东西？

CREATE PROCEDURE qryKeysValues(@KeyValue varchar(5))
AS
BEGIN

  DECLARE @SQL varchar(1500);

  SELECT * INTO #tbl1 FROM FN_qryMethods();

  SET @SQL = 'SELECT ' + @KeyValue+ ' AS fldCode
                 , tbl' +@KeyValue+ 'Key.fldID
                 , #tbl1.fldID
              FROM tbl' + @KeyValue + 'Key, #tbl1';

  EXEC(@SQL);
END;

With语句采用结构：

WITH CTE_Name
AS
(
    Select column from table
)
Select column from CTE_Name

你不能把Declare放在你放的地方。允许的值为SELECT，INSERT，UPDATE，DELETE和MERGE（contrib @alex k）。
