아이폰 앱의 sqlite db 오류 : 해당 테이블이 없습니다

Question

아이폰 애플리케이션의 sqlite 데이터베이스에 데이터를 푸시 할 때 문제가 있습니다. 만들기가 정상으로

-(IBAction)createButtonPressed:(id)sender

모든 것이 : 는 여기에 내가 데이터베이스를 만드는 방법은 다음과 같습니다. 하지만! 가 나는 오류가 내 테이블에 데이터를 밀어하려고하지 않을 때 : "그런 테이블 JOB" 밀어 데이터 코드 :

NSLog(@"populateButtonPressed: called"); 
status.text=[status.text stringByAppendingString:@"populate button pressed.\n"]; 

NSFileManager *filemgr = [NSFileManager defaultManager]; 

if ([filemgr fileExistsAtPath: databasePath ] == YES)

     char *errMsg; 
     const char *sql_stmt; 
     NSString *sqlStatement=[[NSString alloc] init]; 

     /* 
     POPULATING JOB TABLE 
     */ 
     sqlStatement=@"INSERT INTO JOB (NUMBER, DATE_LOADING, DATE_DEPARTURE, DATE_UNLOADING, ORIGIN, DESTINATION, SUPPLIER, RAILROAD, FOREMAN, WEATHER, COMMENT, MODIFY_STATUS) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)"; 

     sql_stmt = [sqlStatement UTF8String]; 
     sqlite3_stmt *stmt; 
     sqlite3_prepare_v2(database, sql_stmt, -1, &stmt, nil); 
     sqlite3_bind_text(stmt, 1, "number", -1, SQLITE_STATIC); //number

     sqlite3_bind_text(stmt, 11, "commentstring", -1, SQLITE_STATIC); //comment 
     sqlite3_bind_int(stmt, 12, 1); 

     if (sqlite3_step(stmt)!=SQLITE_DONE) 
     { 
      status.text=[status.text stringByAppendingString:@"WARNING!!! Could not step (execute) stmt\n"];

     if(sqlite3_finalize(stmt)==SQLITE_DONE) 
     { 
      status.text=[status.text stringByAppendingString:@"finalizing stmt was successfull\n"]; 
     }

     }; 


     status.text=[status.text stringByAppendingString:@"closing database...\n"]; 
     sqlite3_close(database); 

    } 
    else

}; 

[status scrollRangeToVisible:NSMakeRange([status.text length], 0)]; 

데이터베이스 경로에 존재하고 성공적으로 열립니다. iOS5 ipad 응용 프로그램, ARC를 사용하고 libsqlite3.dylib, 시뮬레이터에서 응용 프로그램을 실행하고 있습니다.

db 경로가 맞습니까? 왜 처음에 터미널을 체크인하지 않습니까?
