Question

我非常感谢您对以下问题的帮助;我需要创建一个存储过程，它接受两个参数：

@TableName    
@KeyField

我需要将它们存储到1个变量中，其中值由|

分隔

例如，Customers表如下;

CustomerID     CustomerName         City

111            Adventure            Boston

222             Pubs                 NY

我执行EXEC mysp 'Customers', 111

我需要返回以下结果格式： @ReturnValue = 111|Adventure|Boston

这是我的存储过程;

CREATE PROCEDURE my sp

@table varchar

@key   numeric

AS

@field varchar(40),

@object int


Select @object = object_id from systables where name =@table

--The instructions to create a cursor

WHILE (@@FETCH_STATUS = 0 )


Select @object  = name from sys.columns where object_id = @object

--The instructions to close and deallocate the cursor

--I have already to save the value using the EXEC command but is not working; something like

@String = Select @object from @table where CustomerID = @keyValue

你能帮我吗，

谢谢

我同意jesuraja你需要将关键列的名称作为参数...如果你可以忍受，你可以尝试这样的事情......

declare @tablename nvarchar(max) = 'Customers'
declare @keyfieldName nvarchar(max) = 'CustomerId'
declare @keyfieldValue int = 111

declare @sql nvarchar(max)
set @sql = convert(nvarchar(max), 
    (select (select 'isnull(convert(nvarchar(max), ' + c.name + '), '''') + '' | '' + ')
        from sys.columns c join sys.tables t on c.object_id = t.object_id 
        where t.name = @tablename for xml path('')))
set @sql = 'SELECT ' + SUBSTRING(@sql, 1, len(@sql) - 9) + ' FROM ' + @tablename + 
            ' WHERE ' + @keyfieldName + ' = @keyfieldValue'
exec sp_executesql @sql, N'@keyfieldValue as int', @keyfieldValue

如何将所有字段的值插入变量？
