Invalid operand to binary +

Question

Hi,

I am getting this invalid operand to binary error when I am trying to pass Parcel ID from a text box casted into an integer. Although, I do not need to convert its cast into integer, but I am not sure how can I compare searchBar.text value with "Title_Lookup" fieldAliases?

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
 parcelsQuery = [AGSQuery query];
 NSString *start = searchBar.text;
 int startValue = [start integerValue]; 
 parcelsQuery.where = @Title_Lookup = ' +startValue+ "'";
 parcelsQuery.outFields = [NSArray arrayWithObject:@*];
 [parcelsQueryTask executeWithQuery:parcelsQuery];
 
 [searchBar resignFirstResponder];
 [AGSMapView showNetworkActivityIndicator:YES];
}

On the other hand this code (below) does not throw any exception nor the results?

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
 parcelsQuery = [AGSQuery query];
 parcelsQuery.where = @Title_Lookup = 'searchBar.text';
 parcelsQuery.outFields = [NSArray arrayWithObject:@*];
 [parcelsQueryTask executeWithQuery:parcelsQuery];
 
 [searchBar resignFirstResponder];
 [AGSMapView showNetworkActivityIndicator:YES];
}

Only this code (below) shows me the result, but I want to pass the Parcel ID dynamically right out of text box casted or without casted..any help will do it.
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
 parcelsQuery = [AGSQuery query];
 parcelsQuery.where = @Title_Lookup = '0022884928';
 parcelsQuery.outFields = [NSArray arrayWithObject:@*];
 [parcelsQueryTask executeWithQuery:parcelsQuery];
 
 [searchBar resignFirstResponder];
 [AGSMapView showNetworkActivityIndicator:YES];
}

Hi Nimesh,

Thanks, yeah I fixed it yesterday. Since I came from .Net and didn't know that I need to buildup the string with format before I pass it as a parameter. I've done almost the same thing as you did the code as follow.

parcelsQuery = [AGSQuery query];
self.parcelsQuery.where = [NSString stringWithFormat:@Title_Lookup = '%@'", self.parcelsQuery.text = searchBar.text];
[parcelsQueryTask executeWithQuery:self.parcelsQuery];

GeoSurfInc.Try changing your code like this and see if it works..

parcelsQuery = [AGSQuery query];
 NSString *start = searchBar.text;
 //int startValue = [start integerValue]; 
 //parcelsQuery.where = @Title_Lookup = ' +startValue+ "'";
 parcelsQuery.where = [@Title_Lookup= stringByAppendingString:start];
 parcelsQuery.outFields = [NSArray arrayWithObject:@*];
 [parcelsQueryTask executeWithQueryarcelsQuery];
