Question

我在脚本文件中有以下代码：

sqlcmd -E -I -S MyServerName -d MyDb1 -i D:\Updates\script.sql -o D:\Result\MyDb1.txt
sqlcmd -E -I -S MyServerName -d MyDb2 -i D:\Updates\script.sql -o D:\Result\MyDb2.txt
sqlcmd -E -I -S MyServerName -d MyDb3 -i D:\Updates\script.sql -o D:\Result\MyDb3.txt

我还有更多的数据库要更新，但这只是一个例子，我有一个.bat文件，它读取每个句子并在每个数据库中执行script.sql，这可以正常工作，但是现在我正在使用SQL Data工具生成脚本所以visual studio为我生成了脚本，问题是它创建了变量并在变量中添加了数据库名称，我需要能够每次访问每个数据库时都更新该变量，并以sql模式运行脚本。 / p>

这是MyDb1的script.sql示例：

/*
Deployment script for MyDb1

This code was generated by a tool.
Changes to this file may cause incorrect behavior and will be lost if
the code is regenerated.
*/

GO
SET ANSI_NULLS, ANSI_PADDING, ANSI_WARNINGS, ARITHABORT, CONCAT_NULL_YIELDS_NULL, QUOTED_IDENTIFIER ON;
SET NUMERIC_ROUNDABORT OFF;

GO
:setvar DictionaryData "DictionaryData"
:setvar DatabaseName "MyDb1"
:setvar DefaultFilePrefix "MyDb1"

GO
:on error exit
GO
/*
Detect SQLCMD mode and disable script execution if SQLCMD mode is not supported.
To re-enable the script after enabling SQLCMD mode, execute the following:
SET NOEXEC OFF; 
*/
:setvar __IsSqlCmdEnabled "True"
GO
IF N'$(__IsSqlCmdEnabled)' NOT LIKE N'True'
    BEGIN
        PRINT N'SQLCMD mode must be enabled to successfully execute this script.';
        SET NOEXEC ON;
    END


GO
USE [$(DatabaseName)];
GO

PRINT N'Altering [cimpl].[LanguageView]...';

GO
ALTER VIEW [dbo].[LanguageView]
AS  
    SELECT l.LanguageLabelId, ll.[Name]
      FROM [$(DictionaryData)].[dict].[Language] l
     INNER JOIN [$(DictionaryData)].[dict].[LanguageType] lt
        ON l.[LanguageTypeId] = lt.[LanguageTypeId] 
     INNER JOIN [$(DictionaryData)].[dict].[LanguageLabel] ll
        ON ll.[LanguageLabelId] = l.[LanguageLabelId]    
      LEFT JOIN [cimpl].[LanguageConfiguration] lc
        ON (lc.[LanguageLabelId] = l.[LanguageLabelId]) 
       AND lc.[LanguageTypeId] = lt.[LanguageTypeId]    
       AND lc.[Active] = 1
     WHERE l.Active = 1   

GO

脚本更长，但是作为示例，您可以看到代码是自动生成的，但是对于MyDb1，现在我需要在MyDb2和MyDb3上运行它

如何动态替换句子：

:setvar DatabaseName "MyDb1"

作者：

:setvar DatabaseName "MyDb2" and :setvar DatabaseName "MyDb3"

当时正在运行sqlcmd？

在SQLMode中运行脚本以更改变量
