Question

我有一个带有GO批处理分隔符的SQL脚本，我试图从C＃代码执行。当我使用Microsoft.SqlServer.Management.Common.ServerConnection.ExecuteNonQuery时，效果很好。不过，它会在Microsoft.SqlServer.Management.Common.ServerConnection.ExecuteReader或Microsoft.SqlServer.Management.Common.ServerConnection.ExecuteWithResults上爆炸。

System.AggregateException: One or more errors occurred. --->
Microsoft.SqlServer.Management.Common.ExecutionFailureException: An exception occurred while executing a Transact-SQL statement or batch. --->
System.Data.SqlClient.SqlException: Incorrect syntax near 'GO'.

这是一个非常简单的脚本，如下所示：

SELECT
  DB_NAME()
AS
  'Database Name';
GO

EXEC [schema].[MyStoredProcedure];
GO

SELECT
  [Column]
AS
  'Friendly Column Name'
FROM
  [schema].[Table];
GO

我尝试了script.Replace("\n", "\r\n")，得到的结果相同。有谁知道如何执行这样的脚本和得到结果？

ExecuteReader和ExecuteWithResults不识别批处理分隔符GO。最简单的方法是删除脚本中的GO并调用ExecuteWithResults

脚本

SELECT
  DB_NAME()
AS
  'Database Name';

EXEC [schema].[MyStoredProcedure];

SELECT
  [Column]
AS
  'Friendly Column Name'
FROM
  [schema].[Table];

代码

DataSet ds = Database.ExecuteWithResults(script);
DataTable dbNameTable = ds.Tables[0]; //Select DB_NAME()
DataTable storedProcedureResults = ds.Tables[1]; //Exec [schema].[MyStoredProcedure]
DataTable queryResults = ds.Tables[2];  //Select [Column] From [Schema].[Table]

使用GO批处理分隔符和读取结果执行SQL脚本
