Hi Ken, I'm using EOUtilities.rawRowsForSQL
Here's an example from my code
> public int numOfTotalMessages(EOEditingContext ec) {
> String sqlTerm = "SELECT COUNT(*) FROM PMSMessage WHERE ownerUserID =
> "+this.primaryKey();
> NSArray resultsRows = EOUtilities.rawRowsForSQL(ec, "PMSModel",
> sqlTerm, new NSArray("count"));
> return ((Number) ((NSDictionary)
> resultsRows.objectAtIndex(0)).objectForKey("count")).intValue();
> }
It takes 4 params:
1. an EOEditingContext. Take one you already have or create a new one.
2. the "name" of your model as String.
3. a SQL term. Just write plain SQL or even MySQL dialect (if you use MySQL
only)
3. an array of key-names that are used in the dictionaries returned. In case of
a count-query, it's pretty useless, since you get exactly one result row with a
one-line dict.
OK?
