Only by creating a table and putting the parameters in it (by doing this you can also make the same view return a different subset of records for different users)

i.e. have a table VIEW_PARAMS with columns USERNAME, LOWERLIMIT, UPPERLIMIT

and a view along the lines of

SELECT SOMETHING FROM SOME TABLE WHERE SOMEVALUE BETWEEN VIEW_PARAMS.LOWERLIMIT AND VIEW_PARAMS.UPPERLIMIT AND USER = VIEW_PARAMS.USERNAME Dave Waterworth
