T-SQL - 需要批定界符

Question

I am trying to build Visual Studio solution for Azure SQL Database.

I have SQL script with CREATE TABLE and its extended attributes:

create table schema.table_name (
   table_name_Key integer not null,
   constraint PK_table_Name primary key (table_Name_Key, Some_Column)
)
go

if exists (select 1 from  sys.extended_properties
           where major_id = object_id('table_name') and minor_id = 0)
begin 
   execute sp_dropextendedproperty 'MS_Description',  
   'user', 'schema', 'table', 'table_name' ;
end 

execute sp_addextendedproperty 'MS_Description',  
   'This table will be used for ....', 
   'user', 'schema', 'table', 'table_name';
go

if exists (select 1 from sys.extended_properties p 
           where p.major_id = object_id('table_name')
             and p.minor_id = (select c.column_id from sys.columns c 
                               where c.object_id = p.major_id 
                                 and c.name = 'table_name_Key'))
begin
   execute sp_dropextendedproperty 'MS_Description', 
   'user', 'schema', 'table', 'table_name', 'column', 'table_name_Key';
end

execute sp_addextendedproperty 'MS_Description', 
   'Primary Key of table_name table',
   'user', 'schema', 'table', 'table_name', 'column', 'table_name_Key';
go

I am still getting errors when building that I am missing batch delimiter:

Error SQL71006: Only one statement is allowed per batch. A batch separator, such as 'GO', might be required between statements.

What am I missing and where? I already tried to add go after end but still error.

If you are using SQL Server Data Tools (SSDT) database projects in Visual Studio then you need to think about things differently (and work through some of the tutorials , or this one ).

Basically each object is held in a single script and you do not have to write conditional statements (like IF EXISTS... ). You simply define the object as you want it and SqlPackage.exe works out at deploy-time what the definition should be.

A simple table with one extended property:

CREATE TABLE [testSchema].[table_name] (
    [table_name_Key] INT          NOT NULL,
    [Some_Column]    VARCHAR (10) NOT NULL,
    CONSTRAINT [PK_table_Name] PRIMARY KEY CLUSTERED ([table_name_Key] ASC, [Some_Column] ASC)
);


GO
EXECUTE sp_addextendedproperty @name = N'Caption', @value = 'Some_column is a required column.', @level0type = N'SCHEMA', @level0name = N'testSchema', @level1type = N'TABLE', @level1name = N'table_name', @level2type = N'COLUMN', @level2name = N'Some_Column';

Define your table in a similar manner to above, press Build and work through the errors.
