在标签中传递SQL结果

Question

我有一个选择语句，可以查询获得高分的前5名球员

selectStmt = new SQLStatement();
selectStmt.sqlConnection = conn;            
selectStmt.text="SELECT name, level, score FROM highscores WHERE ROWID <=5 ORDER BY score DESC";        
selectStmt.execute();

我希望标签中显示的名称，级别和分数。如何在标签中传递结果？

Answer 1

你必须：

1. 倾听SQLEvent.RESULT
2. 执行您的查询
3. 处理结果

selectStmt = new SQLStatement();
selectStmt.sqlConnection = conn;
selectStmt.text="SELECT name, level, score FROM highscores WHERE ROWID <=5 ORDER BY score DESC";

// Create a listener in order to process the results
var resultHandler:Function = function(event:SQLEvent):void {
    selectStmt.removeEventListener(SQLEvent.RESULT, resultHandler);

    // Get the result
    var result:SQLResult = dbStatement.getResult();
    if (result != null) {
        // Iterate through each entries
        for each (var entry:Object in result.data) {
            // Trace entry
            trace(entry.name, entry.level, entry.score);
        }
    }
};

// Add a listener in order to read the results when the request will be done
selectStmt.addEventListener(SQLEvent.RESULT, resultHandler);
selectStmt.execute();
