Use stringByReplacingCharactersInRange to replace only the first ‘AND’:

NSString* s = @"Select *  from Store_Master where AND  VDivison = 'Casual Dining' AND VBrand_Name = 'Pinkberry' AND VCountry_Name = 'Egypt' AND VCity = 'Cairo' AND VBuilding_mall_name = 'Dandy Mega Mall' GROUP BY VStore_Name";
NSRange replaceRange = [s rangeOfString:@"AND"];
if (replaceRange.location != NSNotFound){
    NSString* result = [s stringByReplacingCharactersInRange:replaceRange withString:@""];
}

That would result in:

Select *  from Store_Master where   VDivison = 'Casual Dining' AND VBrand_Name = 'Pinkberry' AND VCountry_Name = 'Egypt' AND VCity = 'Cairo' AND VBuilding_mall_name = 'Dandy Mega Mall' GROUP BY VStore_Name

EDITED:

If you want to remove the occurrences of AND in a case insensitive way (no matter uppercase of lowercase), use the NSStringCompareOptions when you create the NSRange, like this:

NSRange replaceRange = [s rangeOfString:@"and" options:NSCaseInsensitiveSearch];

The rest of the code is the same.
