请帮忙改个存储过程
CREATE   PROCEDURE   dbo.SaveSpeed
@TableName   varchar(80)   =   NULL,  
@Speed1     float   =   NULL,        
@Speed2   int       =   NULL,
@fTime     float   =   NULL,
@iIndex   int       =   NULL
AS

IF   @TableName   IS   NULL   or   @Speed1   IS   NULL   or   Speed2   IS   NULL   or   fTime   IS   NULL   or   iIndex   IS   NULL
BEGIN
      PRINT   'ERROR:   You   must   specify   a   value. '
      RETURN
END

--   INSERT   the   alert   value   to   the   specified   Table.
INSERT   INTO   [str(TableName)]     VALUES   (@Speed1,@Speed2,@fTime,@iIndex)

RETURN
GO

这个存储过程在检查语法时提示错误，请大家帮忙改一下，谢了。
