Question

此脚本无法从PowerShell（sqlcmd）直接从SQL Management Studio执行：

IF db_id('BANANATEST') is not null
 BEGIN   
  print 'DB BANANATEST already exists. NO ACTION TAKEN.'
 END
ELSE
 BEGIN
  print 'DB BANANATEST does NOT exist.'
  print 'Restoring a backup of BANANATEST'
  RESTORE DATABASE BANANATEST
   FROM DISK = 'BANANATEST.original.bak' ;

  print 'Creating User BANANATEST'
  USE master
  If Exists (select loginname from master.dbo.syslogins where name ='BANANATEST')
  Begin
   DROP LOGIN [BANANATEST]
  END
  CREATE LOGIN [BANANATEST] WITH PASSWORD=N'BANANATEST', DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
  USE BANANATEST
  ALTER USER [BANANATEST] WITH LOGIN = [BANANATEST]
END

错误是语法。

Msg 911，Level 16，State 1，Line 20数据库'BANANATEST'没有存在。确保正确输入名称。

虽然准确，但在查询“编译”时不存在BANANATEST DB ... SQL Server没有意识到数据库 WILL 在到达此行时存在。

如何让它工作？要么忽略语法检查，要么忽略它的工作......

注意：备份附带一个BANANATEST usr，我想介绍两种情况：

LOGIN已存在于SQL Server
登录不存在

你可以使用#temp tables

来解决这个问题

CREATE table #temp12 (restore1  bit)
IF db_id('BANANATEST') is not null
 BEGIN   
  print 'DB BANANATEST already exists. NO ACTION TAKEN.'
 END
ELSE
 BEGIN
  print 'DB BANANATEST does NOT exist.'
  print 'Restoring a backup of BANANATEST'
  RESTORE DATABASE BANANATEST
   FROM DISK = 'BANANATEST.original.bak' ;
  INSERT INTO #temp12 VALUES ('1')
  print 'Creating User BANANATEST'
 END 
 GO
  USE master
  IF EXISTS (SELECT 1 from #TEMP12)
      BEGIN
      If Exists (select loginname from master.dbo.syslogins where name ='BANANATEST')
      Begin
       DROP LOGIN [BANANATEST]
      END
      CREATE LOGIN [BANANATEST] WITH PASSWORD=N'BANANATEST', DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
      USE BANANATEST
      ALTER USER [BANANATEST] WITH LOGIN = [BANANATEST]
  END
DROP TABLE #temp12

如何执行这个语法检查不允许的t-sql脚本？
