How I can select a record in a column with Largest/MAX value in "Definition Query" in ArcMap?
for example, i have a feature with 10 records
in the ID column; the records are 1, 2, 3,4,5,6,7,8,9,10
in the "Definition Query", i would like to select on the largest ID record
i have tried all kinds of MAX sql but they didn't work, any ideas?
ID >= MAX(ID)
"ID" >= MAX("ID") ....etc
The syntax would be
ID = (SELECT MAX(ID) FROM table)
Just a note of caution, using subqueries in definition queries isn't ideal. Depending on the complexity of the data set and the subquery itself, there can be performance or portability issues.
This query selects the record with the maximum value... the 'select … from … ' syntax
buried a bit in ...

I am have a problem with the syntax Hopefully someone can assist. When i type in the sql expression Pro 2.5 finds an error but i can't seem to find what the errors is. I even copied the script directly from the blog and only changed out the fields and table, but still no luck

GDP2006 > (SELECT MAX(GDP2005) FROM countries)
Not sure if or why but the query is on a stand alone table
Check the database / schema , and permissions to table / layer
(SELECT MAX(GDP2005) FROM gisdata.dbo.countries)
