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。
