Question

我试图通过使用mysql从文本字段中获取日期，并且我只获取了年份（2017）这是我的问题：

theQuery("insert into Files11(FileName,Date,Coding,Demo,Audit,Lop,Denials,Cs,Comments,Percentage) values('"+JT_FileName.getText()+"','"+JT_Date1.getText()+"','"+Coding.getText()+"','"+Demo.getText()+"','"+Audit.getText()+"','"+Lop.getText()+"','"+Denials.getText()+"','"+Cs.getText()+"','"+Comments.getText()+"','"+Percentage.getText()+"')");

以前我使用此查询获取完整日期：

theQuery("insert into Files5(FileName,LinesCount,UserId,Date) values('"+JT_FileName.getText()+"','"+JT_LinesCount.getText()+"','"+text.getText()+"','"+JT_Date1.getText()+"')");

获取：我使用过这个查询

String sql = "SELECT * FROM Files11";

任何人都可以帮助我，我在这里缺少什么？这是我的整个源代码：

Answer 1

这是由于粗心的错误，我返回了整数（Rs.getint）而不是String（Rs.getString）。这很有趣，但我花了很多时间才找到。

我试图从textfield获取日期，但我只获得了一年（2017年）获取
