Problem in data binding in NSString?
- by Rajendra Bhole
Hi,
I selecting the row of the table. The text of the row i stored in the application delegate object as a NSString. That NSString i want to retrieving or binding in SELECT statement of SQLite query, For that i written code in the TableView Class
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
selectedText = [appDelegate.categoryArray objectAtIndex:indexPath.row];
appDelegate.selectedTextOfRow = selectedText;
ListOfPrayersViewController *listVC = [[ListOfPrayersViewController alloc] init];
[self.navigationController pushViewController:listVC animated:YES];
[listVC release];
}
and database class class code is.
+ (void) getDuas:(NSString *)dbPath{
if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK){
SalahAppDelegate *appDelegate = (SalahAppDelegate *)[[UIApplication sharedApplication] delegate];
NSString *categoryTextForQuery =[NSString stringWithFormat:@"SELECT Category FROM Prayer WHERE Category ='%s'", appDelegate.selectedTextOfRow ];
NSLog(@"The Text %@", categoryTextForQuery);
//const char *sqlQuery1 = (char *)categoryTextForQuery;
//const char *sqlQuery = "SELECT Category FROM Prayer WHERE Category = 'Invocations for the beginning of the prayer'";
sqlite3_stmt *selectstmt;
if(sqlite3_prepare_v2(database, [categoryTextForQuery UTF8String], -1, &selectstmt, NULL) == SQLITE_OK){
appDelegate.duasArray =[[NSMutableArray alloc] init];
while(sqlite3_step(selectstmt) == SQLITE_ROW){
NSString *dua = [[NSString alloc] initWithCString:(char *)sqlite3_column_text(selectstmt,0) encoding:NSASCIIStringEncoding];
Prayer *prayerObj = [[Prayer alloc] initwithDuas:dua];
prayerObj.DuaName = dua;
[appDelegate.duasArray addObject:prayerObj];
}
}
}
}
The code is comes out of loop on the statement or starting the loop of the
while(sqlite3_step(selectstmt) == SQLITE_ROW)
Why?
How i bind the table selected text in SELECT statement of sqlite?
