带变量的表和返回值的动态SQL输出

该过程本身作为查询工作，但在另一过程中调用时不起作用;因为我看不到变量值填充时我调试

任何帮助表示赞赏？

  Exec dbo.usr_GetLastDate @TableName, @LastTransDate 
      EXEC dbo.usr_GetRecCount @TableName, @RecCount 

ALTER PROCEDURE [dbo].[usr_GetLastDate] 
    -- Add the parameters for the stored procedure here 
    @TableName SYSNAME, 
    @OUTDATE date Output 
AS 
BEGIN 
    -- SET NOCOUNT ON added to prevent extra result sets from 
    -- interfering with SELECT statements. 
    SET NOCOUNT ON; 

    -- Insert statements for procedure here 
    DECLARE @SQLCommand NVARCHAR(MAX) = 
     N'SELECT @OUTDATE=MAX(TRANSDATE) FROM ' + QUOTENAME(@TableName); 

    EXECUTE [dbo].[sp_executesql] 
      @sqlCommand, N'@OUTDATE DATE OUTPUT', @[email protected] OUTPUT; 

END 

ALTER PROCEDURE [dbo].[usr_GetRecCount] 
    -- Add the parameters for the stored procedure here 
    @TableName SYSNAME, 
    @OUTINT int output 

AS 
BEGIN 
    -- SET NOCOUNT ON added to prevent extra result sets from 
    -- interfering with SELECT statements. 
    SET NOCOUNT ON; 

    -- Insert statements for procedure here 
    DECLARE @SQLCommand NVARCHAR(MAX) = 
     N'SELECT @OUTINT=COUNT(SYMBOL) FROM ' + QUOTENAME(@TableName); 


    EXECUTE [dbo].[sp_executesql] 
      @sqlCommand, N'@OUTINT INT OUTPUT', @[email protected] OUTPUT; 
END

你为什么要标记mysql和sql-server？ –

您需要回访您之前询问的问题并接受帮助您的答案。 –

如果您使用的Visual Studio 你可以看到在变量窗口中的所有变量的值。表达式只有在有范围时才会显示值，但有时它们不会按照我们想要的方式表现。

所以我的建议是你应该使用“变量”窗口来查看所有变量及其值。

你需要传递的输出变量的程序

Exec dbo.usr_GetLastDate @TableName, @LastTransDate OUTPUT 
EXEC dbo.usr_GetRecCount @TableName, @RecCount OUTPUT

是：工作的最终代码时使用的关键字输出。谢谢大家
