C# 以编程方式更改存储过程

Question

我有以下 C# 代码应该允许我修改（更改）我的存储过程：

SqlConnection sqlCon = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlConnection"].ConnectionString);
ServerConnection srvCon = new ServerConnection(sqlCon);

sqlCon.Open();

Server srv = new Server(srvCon);
Database db = srv.Databases[sqlCon.Database];
StoredProcedure sp = new StoredProcedure(db, "spRDLDataFetcher");

sp.TextMode = false;
sp.AnsiNullsStatus = false;
sp.QuotedIdentifierStatus = false;
sp.TextBody = "SELECT blah FROM MyTable WHERE ID=1";
sp.Alter();

但是，sp.Alter()call 会引发此错误：

Microsoft.SqlServer.Management.Smo.FailedOperationException：'StoredProcedure 'dbo.spRDLDataFetcher' 的更改失败。 '

内部异常：InvalidSmoOperationException：您无法对处于Creating 状态的对象执行Alter 操作。

为了让它改变（更新）该存储过程，我缺少什么？

Answer 1

好的，所以我发现了它为什么不更新它。似乎，无论出于何种原因，在我覆盖 textBody 之前，它都需要 sp.Refresh(); First。

SqlConnection sqlCon = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlConnection"].ConnectionString);
ServerConnection srvCon = new ServerConnection(sqlCon);

sqlCon.Open();

Server srv = new Server(srvCon);
Database db = srv.Databases[sqlCon.Database];
StoredProcedure sp = new StoredProcedure(db, "spRDLDataFetcher");

sp.TextMode = false;
sp.AnsiNullsStatus = false;
sp.QuotedIdentifierStatus = true;
sp.ImplementationType = ImplementationType.TransactSql;
sp.Schema = "dbo";

sp.Refresh(); //What was needed to make work
string orgSPText = sp.TextBody;

sp.TextBody = "SELECT blah FROM MyTable WHERE ID=1";
sp.Recompile = true;
sp.Alter();

sp.Recompile = true; 确实是不需要的。没有它它也能工作，但我喜欢把它放在那里只是为了好玩和咯咯笑。
