Sqlite查询不起作用

Question

我想获取特定行类型的所有行详细信息。

Select * from MainTable where JOB1=@Paint 

这不起作用。我尝试了更多的选择，但没有取得成功。任何人都可以告诉我Objective-C中正确的格式是什么？

完整的代码是这样

if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) { 
    //const char *sqlStatement = "SELECT * FROM MainTable"; ??it is working 

    const char *sqlStatement = "SELECT * FROM MainTable where JOB1='Paint'";//but not this one 


    sqlite3_stmt *compiledStatement; 
    NSLog(@"query set"); 

    if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) { 

     while(sqlite3_step(compiledStatement) == SQLITE_ROW) { 

      NSString *job = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 0)]; 
      NSString *image = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)]; 
      NSString *tools = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)]; 
      NSString *materials = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 3)]; 
      NSString *people = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 4)]; 
      NSString *safety = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 5)]; 
      NSLog(@"%@",job); 
      NSLog(@"image %@",image); 
      NSLog(@"tools %@",tools); 
      NSLog(@"materials %@",materials); 
      NSLog(@"people %@",people); 
      NSLog(@"safety %@",safety);

你可以火的SQLite数据库的查询用firefox插件SQLite的经理

相同的查询，你可以写程序。如果仍然没有运行，请发布您的代码片段。
