Question

我想知道是否有办法从SQL Server 2008 R2中获取存储过程代码？

例如，如果我有以下代码来创建此存储过程：

USE AdventureWorks;  
GO  
CREATE PROCEDURE HumanResources.uspGetEmployeesTest2   
    @LastName nvarchar(50),   
    @FirstName nvarchar(50)   
AS   

    SET NOCOUNT ON;  
    SELECT FirstName, LastName, Department  
    FROM HumanResources.vEmployeeDepartmentHistory  
    WHERE FirstName = @FirstName AND LastName = @LastName  
    AND EndDate IS NULL;  
GO

有没有办法可以编写SQL语句来获取'SET NO COUNT ON' to 'IS NULL'之间的所有内容？

非常简单，实际上 - 只需加入sys.procedures和sys.sql_modules系统目录视图即可获取存储过程定义。

这个C＃代码说明了这种方法：

string connectionString = "server=YourServerName;Database=YourDatabaseName;Integrated Security=SSPI;";

string query = @"SELECT m.definition 
                 FROM sys.procedures pr 
                 INNER JOIN sys.schemas s ON pr.schema_id = s.schema_id
                 INNER JOIN sys.sql_modules m ON pr.object_id = m.object_id 
                 WHERE pr.Name = @Name AND s.Name = @Schema;";

using (SqlConnection conn = new SqlConnection(connectionString))
using (SqlCommand cmd = new SqlCommand(query, conn))
{
    cmd.Parameters.Add("@Name", SqlDbType.VarChar, 255).Value = "uspGetEmployeesTest2";
    cmd.Parameters.Add("@Schema", SqlDbType.VarChar, 255).Value = "HumanResources";

    conn.Open();
    object returnValue = cmd.ExecuteScalar();
    conn.Close();

    if (returnValue != null)
    {
        string procedureDefinition = returnValue.ToString();
    }
}

这将返回所有内容 - 从CREATE PROCEDURE到程序的最后一行

不确定。一种方法是戳INFORMATION_SCHEMA.ROUTINES。在查询编辑器中，您可以这样：

SELECT ROUTINE_NAME, ROUTINE_DEFINITION
FROM INFORMATION_SCHEMA.ROUTINES
WHERE 
    ROUTINE_SCHEMA = 'HumanResources' 
    AND ROUTINE_NAME = `uspGetEmployeesTest2`

然后，您可以使用WHERE和LIKE进一步优化所需的文字。
