  Hi All,

  i have to estimate the table size based on the no of rows.

  If user enters table name and no of rows, i need to tell teh size occupied by the rows.

  Can somebody help on this.

  Create procedure Estimate(

  @Rows int

  ,@TableName varchar(32)

  )

  AS

  select sum(length)* @Rows AS SizeInBytes

  from sys.syscolumns

  where id = object_id(@TableName)

  But this code will give you the maximum size your row will occupy because it sums the size defined of all the variable data types (like varchar).
