Dynamic SQL - varchar(2000) variable only holding 255 characters

I am trying to create a dynamic sql statement in a stored procedure.  The final @sQuery variable ends up holding

"declare @tableOut table ( [RowNo] [int] identity (1, 1) Primary key NOT NULL , [Id0] [uniqueidentifier] NULL , [Name0] [nvarchar](50) NULL , [Id1] [uniqueidentifier] NULL , [Name1] [nvarchar](50) NULL , [Id2] [uniqueidentifier] NULL , [Name2] [nvarchar](5"

which happens to be 255 characters long???

The following is the code:

                declare @sQuery varchar(2000) ,
                            @iLastLevel int ,
                            @iLevels int
               
                set @sQuery = ''
      set @iLevels = 4
                set @iLastLevel = @iLevels - 1
      
      if ( @iLevels < 1 )
      begin
            return 0
      end

      set @iLastLevel = @iLevels - 1      
      
      set @sQuery = 'declare @tableOut table ( [RowNo] [int] identity (1, 1) Primary key NOT NULL , '
      
      while @iIndex < @iLevels
      begin
            set @sId = '[Id' + ltrim ( rtrim ( cast( @iIndex as varchar ( 3 ) ) ) ) + ']'
            set @sName = '[Name' + ltrim ( rtrim ( cast( @iIndex as varchar ( 3 ) ) ) )+ ']'

            set @sQuery = @sQuery + @sId + ' [uniqueidentifier] NULL , '
            set @sQuery = @sQuery + @sName + ' [nvarchar](50) NULL , '

            if @iIndex = @iLastLevel
            begin
                  set @sQuery = @sQuery + ' [BottomLevelId] [uniqueidentifier] NOT NULL ) '
            end

            set @iIndex = @iIndex + 1
      end

      exec ( @sQuery )

Go to the connection properties in Query analyzer and tell it to DISPLAY more than 255 chars....

How do you know that's how long it is? Are you printing the variable or using profiler to see it. Profiler truncates SQL

AaronAbendCommented:
Actually the setting is in the Query Analyzer -> Options -> Results toolbar. Are you using GRID or Text for your output?

I was using the locals window in Query Analyzer.  When i use the Print statement, it seems to be fine.

Thanks

"I was using the locals window in Query Analyzer. "

So you accept an answer relating to Profiler?
