[Info-ingres] One up unique number for an attribute - in SQL - does anyone know the trick of doing this?

[Allan Biggs]

in command line sql I am populating a new table - one of the columns is a 
sort order 

each row of this field  must be a 'one up' unique number starting at 1 and 
ending as the number of rows in the table 


I know that I could do this in OpenROAD , and in another guise this is 
done in OpenROAD,  but in this case it has to be done in SQL or maybe in 
report writer.

It does not matter  which rows contain  1 ,2 etc although one of the 
columns does have a set of unique numbers with gaps which could be used to 
determine the order of row 1, 2 etc. 

Does anyone know of a 'trick' to do this?

In mysql it is possible to define unique one up numbers when creating a 
table does modern Ingres have this feature?

thanks 
Allan
