ios - Getting unable to open database file while inserting bulk data in sqlite db -


i using following code insert rows more 5000 in ios app. if not using line sqlite3_close(dbv); statement got error unable open database. , if use statement sqlite3_close(dbv) data insertion taking around 10-15 mins. can insert record faster without getting error.

-(void)insertrecordintotable:(nsstring*)sqlstatement {     nsstring *sqlstr=sqlstatement;     const char *sql=[sqlstr utf8string];      const char* key = [@"strongpassword" utf8string];     sqlite3_stmt *statement1;     @try {          int res = sqlite3_open([[self.databaseurl path] utf8string], &dbv);         if (res != sqlite_ok)             sqlite3_open([[self.databaseurl path] utf8string], &dbv);          sqlite3_key(dbv, key, (int)strlen(key));          if(sqlite3_prepare_v2(dbv, sql, -1, &statement1, nil)==sqlite_ok)         {             nslog(@"done");         }         else         {              nslog(@"the error occurred here %s ",sqlite3_errmsg(dbv));         }          res =sqlite3_step(statement1);          if(res !=sqlite_done)           nslog(@"error upadating table");          sqlite3_finalize(statement1);         sqlite3_close(dbv);     }     @catch (nsexception *exception) {      }     @finally {         sql=null;         sqlstr=null;         sqlstatement=null;     } }

after opening database add code 

sqlite3_exec(mdb, "begin transaction", null, null, &errormessage);

and, before closing database add code

sqlite3_exec(mdb, "commit transaction", null, null, &errormessage);
