首先建立表

CREATE TABLE [dbo].[ColumnIpParameter] (
  [ColumnIp_ip] int  IDENTITY(1,1) NOT NULL,
  [Columnlp_typeid] int  NULL,
  [Columnlp_Listing] varchar(50) COLLATE Chinese_PRC_CI_AS  NULL,
  [Columnlp_port] varchar(50) COLLATE Chinese_PRC_CI_AS  NULL,
  CONSTRAINT [PK_ColumnIpParameter] PRIMARY KEY CLUSTERED ([ColumnIp_ip])
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)  
ON [PRIMARY]
)  
ON [PRIMARY]
GO

ALTER TABLE [dbo].[ColumnIpParameter] SET (LOCK_ESCALATION = TABLE)

修改  儲存過程名字(ColumnIp) 行轉列表(ColumnIpParameter) 分組欄位(Columnlp_typeid)  行變列的欄位(Columnlp_Listing)      行變列值的欄位(Columnlp_port) 這幾個欄位  就可以使用了   需要在SQL Server Management Studio裡面使用,不要在

ALTER PROCEDURE ColumnIp
    //如果不需要帶引數,那就不需要寫
AS
BEGIN
    DECLARE @sql_str NVARCHAR(MAX)
DECLARE @sql_col NVARCHAR(MAX)
DECLARE @sql_where NVARCHAR(MAX)
DECLARE @tableName SYSNAME --行轉列表
DECLARE @groupColumn SYSNAME --分組欄位
DECLARE @row2column SYSNAME --行變列的欄位
DECLARE @row2columnValue SYSNAME --行變列值的欄位
SET @tableName = 'ColumnIpParameter'  
SET @groupColumn = 'Columnlp_typeid'
SET @row2column = 'Columnlp_Listing'
SET @row2columnValue = 'Columnlp_port'
SET @sql_where = 'WHERE Columnlp_typeid = 1'

--從行資料中獲取可能存在的列
SET @sql_str = N'
SELECT @sql_col_out = ISNULL(@sql_col_out + '','','''') + QUOTENAME(['[email protected]+'])
    FROM ['[email protected]+']  GROUP BY ['[email protected]+']'
--PRINT @sql_str
EXEC sp_executesql @sql_str,N'@sql_col_out NVARCHAR(MAX) OUTPUT',@[email protected]_col OUTPUT
--PRINT @sql_col

SET @sql_str = N'
SELECT * FROM (
    SELECT ['[email protected]+'],['[email protected]+'],['[email protected]+'] FROM ['[email protected]+']'[email protected]_where+') p PIVOT
    (max(['[email protected]+']) FOR ['[email protected]+'] IN ( '+ @sql_col +') ) AS pvt
ORDER BY pvt.['[email protected]+']'
--PRINT (@sql_str)
EXEC (@sql_str)
END

 

執行例項 SQL Server Management Studio 查詢裡面執行

下面是執行效果
