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.
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)
