Msg 137,Level 15,State 1,Line 1
Must declare the scalar variable “@dbstatus”.

我以为我已经声明了变量,所以我不知道为什么它仍然抛出错误？

DECLARE @dbname nvarchar(100) 
DECLARE @dbstatus varchar(500) 
DECLARE @sqlCommand NVARCHAR(1000) 
create table #temptable (dbname nvarchar(100),status varchar(500))

DECLARE c1 CURSOR READ_ONLY 
FOR 
   SELECT '[' + name + ']'   FROM sys.databases WHERE name = 'EDDS1084543'

OPEN c1  
FETCH NEXT FROM c1 INTO @dbname 

WHILE @@FETCH_STATUS = 0 
BEGIN            
      SET @sqlCommand = 'SET @dbstatus = (SELECT Status FROM ' + @dbname + '.[EDDSDBO].[dtSearchIndex])'   

      EXECUTE sp_executesql @sqlCommand

      INSERT INTO #tempTable(dbname,[status])VALUES (@dbname,@dbstatus)

      FETCH NEXT FROM c1 INTO @dbname   
END   

CLOSE c1 
DEALLOCATE c1
