使用ExecuteSqlCommand从文本文件创建存储过程

Question

我正在尝试执行一个sql文本文件，以便在sql server数据库上创建存储过程。我还使用此方法创建用户定义的表类型，存储过程将使用这些表类型。

表类型的创建非常有效。然而，当我去创建存储过程时，我得到了错误，"CREATE/ALTER PROCEDURE"必须是查询批处理中的第一条语句。

以下是读取文件并对数据库执行的代码：

public static void LoadStoredProcedures()
    {
        const string procedureLocation = "C:\StoredProcedures.txt";
        var reader = File.ReadAllText(procedureLocation);
        var context = new prismEntities();
        context.Database.ExecuteSqlCommand(reader);

    }
    public static void CreateTables()
    {
        const string tableLocation = "C:\CreateTables.txt";
        var reader = File.ReadAllText(tableLocation);
        var context = new prismEntities();
        context.Database.ExecuteSqlCommand(reader);
    }

用户定义表的一个示例：

if not exists (select * from sys.table_types
where name like 'TextbookTable')
create type [dbo].[TextbookTable] as table (
[TXUID] [int] NOT NULL,
[SKU] [int] NOT NULL,
[UsedSKU] [int] NOT NULL,
[BindingID] [int] NOT NULL,
[TextStatusID] [int] NOT NULL,
[StatusDate] [datetime] NULL,
[Author] [char](45) NOT NULL,
[Title] [char](80) NOT NULL,
[ISBN] [char](30) NULL,
[Imprint] [char](10) NULL,
[Edition] [char](2) NULL,
[Copyright] [char](2) NULL,
[Type] [char](10) NULL,
[Bookkey] [varchar](10) NULL,
[Weight] [decimal](10, 4) NULL,
[ImageURL] [char](128) NULL,
primary key clustered
(
    [TXUID] ASC
) with (ignore_dup_key = on)
)

我试图创建的存储过程的一个示例：

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[AddTextbook]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[AddTextbook]
create procedure [dbo].[AddTextbook]
(
@textbook TextbookTable readonly
)
as
begin
set nocount on;
set identity_insert textbook on
begin try
merge Textbook txt
using (select * from @textbook) as source
    on txt.TXUID = source.TXUID
when not matched then
    insert (TXUID, SKU, UsedSKU, BindingID, TextStatusID, StatusDate, Author,
            Title, ISBN, Imprint, Edition, Copyright, Type, Bookkey, Weight, ImageURL)
    values ( source.TXUID, source.SKU, source.UsedSKU, source.BindingID, source.TextStatusID,
             source.StatusDate, source.Author, source.Title, source.ISBN,
             source.Imprint, source.Edition,
             source.Copyright, source.Type, source.Bookkey, source.Weight, source.ImageURL);
set identity_insert textbook off    
end try
begin catch
    declare @message varchar(128) = error_message()
    select
     ERROR_NUMBER() as ErrorNumber,
     ERROR_SEVERITY() as ErrorSeverity,
     ERROR_STATE() as ErrorState,
     ERROR_PROCEDURE() as ErrorProcedure,
     ERROR_LINE() as ErrorLine,
     ERROR_MESSAGE() as ErrorMessage;
     raiserror(@message, 16, 10)
end catch
end
grant execute on [dbo].[AddTextbook] to [public]

现在，调用的顺序是先调用CreateTables，然后调用LoadStoredProcedures。创建这些表没有任何问题。存储过程不会被创建并生成上述错误。我已删除"如果存在…"行和存储过程将被创建，但是，如果我试图在同一个文件中创建其他文件，它们将出错而无法创建。我希望能够用一个文件来管理它，而不是为每个存储过程使用多个文件。

有人知道这方面的变通办法吗？希望我已经提供了充足的信息。提前谢谢。

基本上，命令之间缺少一堆GO语句，例如：

你必须更改

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[AddTextbook]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[AddTextbook]
create procedure [dbo].[AddTextbook]

成为

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[AddTextbook]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[AddTextbook]
GO
create procedure [dbo].[AddTextbook]
