Question

我正在尝试连接SQL Server并在安装设置时执行脚本文件。我设法执行一个没有GO语句的简单脚本。

问题：有没有办法传递（跳过）GO字并执行脚本？

 ADOConnection.ConnectionString :=
      'Provider=SQLOLEDB;' +  
        'Data Source=' + ServerEdit.Text + ';' +
        'User Id=' + UsernameEdit.Text + ';' +
        'Password=' + PasswordEdit.Text + ';' + 
        'Trusted_Connection=no;';
  end;

 ADOConnection.Open;
try

  ADOCommand := CreateOleObject('ADODB.Command');
  ADOCommand.ActiveConnection := ADOConnection;
  ScriptPath := ExpandConstant('{tmp}\Script2.sql');

  if LoadStringFromFile(ScriptPath, ssquery) then
  begin
   StringChangeEx(ssquery, 'GO', '', True);
    SQLQuery :=  ssquery
    ADOCommand.CommandText := SQLQuery;
    ADOCommand.Execute(NULL, NULL, adCmdText or adExecuteNoRecords);
    Result := True;
  end;
finally
  ADOConnection.Close;
  end;

Script2.sql

USE northwind3

GO
/****** Object:  StoredProcedure [dbo].[Customers By City]    Script Date: 5/25/2016 8:35:45 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO


CREATE PROCEDURE [dbo].[Customers By City]
    -- Add the parameters for the stored procedure here
    (@param1 NVARCHAR(20))
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;
    SELECT CustomerID, ContactName, CompanyName, City from Customers as c where c.City=@param1
END


GO
/****** Object:  StoredProcedure [dbo].[Customers Count By Region]    Script Date: 5/25/2016 8:35:45 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[Customers Count By Region]
    -- Add the parameters for the stored procedure here
    (@param1 NVARCHAR(15))
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;
    DECLARE @count int
    SELECT @count = COUNT(*)FROM Customers WHERE Customers.Region = @Param1
    RETURN @count
END

注意：我以类似的方式使用ADOB进行连接TLama's回答How to connect to MS SQL Server using InnoSetup?除了我的情况，我必须在我的脚本中包含GO。

谢谢。

您可以将SQL脚本拆分为单独的脚本文件，而不是go语句，并按顺序单独执行。

如果这不是一个选项，则必须使用支持go语句的API /工具，即sqlcmd工具，而不是ADO。

或者只是在通过ADO执行脚本之前加载脚本文件并删除go语句。

您可以使用StringChange function。
