Question

I want to use sqlite3 for my iphone application. But it is not working. Scenario is :- On click event of a button a method should run and retrieve the data from the database. But My sequence of program is not going into

if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) {
    const char *sqlStatement = "select * from records";
    sqlite3_stmt *compiledStatement;
    0NSLog(@"%s", sqlite3_errmsg(database)); // Results - no error
-
    if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK)    {
//here NSLog statement does not work.

There is no problem in opening a database. What should be the reason? Any solution appreciable.
Thanks

Here is a modified example of my own code :

  NSString *file = @"youdatabase.db"
  sqlite3 *db;    
  if(sqlite3_open([file UTF8String], &db) == SQLITE_OK)
  {
    NSString *req = @"SELECT * FROM totoTable";
    sqlite3_stmt *returnReq;

    if(sqlite3_prepare(db, [req cStringUsingEncoding:NSUTF8StringEncoding], -1, &returnReq, NULL) == SQLITE_OK)
    {
      while (sqlite3_step(returnReq) == SQLITE_ROW)
      {
         //Printf first returned value
        NSLog(@"%s", (char*)sqlite3_column_text(returnReq, 0));
      }     
    }
    sqlite3_close(db);
  }

Hope it will help you 😉
