sql server CLR

1. 配置sql server 启用CLR

在SQL Server2005/2008里面，CLR默认是关闭的。可以使用如下SQL语句开启CLR。 
sp_configure 'show advanced options', 1; 
GO 
RECONFIGURE; 
GO 
sp_configure 'clr enabled', 1; 
GO 
RECONFIGURE; 
GO

2. 编写对应的.net 代码

[Microsoft.SqlServer.Server.SqlProcedure()]
        public static void firstapp1()
        {
            SqlCommand cmd = new SqlCommand("select * from teptable1");
            SqlContext.Pipe.ExecuteAndSend(cmd);

}

3. 添加程序集

如下图：

4. 编写调用的sql

CREATE PROCEDURE [dbo].firstapp1
AS EXTERNAL NAME [MyCLR].[MyCLR.CLRDemo].firstapp

注意调用的写法

5. 客户端调用方法

using (SqlConnection connection = new SqlConnection(@"Data Source=.\sql2012;Initial Catalog=buckInsert;User ID=sa;ApplicationIntent=ReadOnly;password=1234"))
            {
                DataSet ds = new DataSet();

SqlCommand command = new SqlCommand();
                command.Connection = connection;
                command.CommandType = CommandType.StoredProcedure;
                command.CommandText = "firstapp1";
                SqlDataAdapter dp = new SqlDataAdapter(command);
                dp.Fill(ds);
                DataTable dt = ds.Tables[0].Copy();

foreach (DataRow item in ds.Tables[0].Select("id<1000"))
                {
                    dt.ImportRow(item);
                }
                dataGridView1.DataSource = dt;
            }

6. ssis 调用sql

exec firstapp1

7.测试结果

以上为测试的结果
