你可以在数据展示页面添加一个QLineEdit和一个QPushButton,让用户输入员工ID并点击按钮进行筛选。
具体实现方法如下:
1. 在QueryResultWindow类的初始化函数中添加以下代码来创建QLineEdit和QPushButton:
```
self.id_line_edit = QLineEdit()
self.filter_button = QPushButton('筛选')
self.filter_button.clicked.connect(self.filter_result)
```
2. 在layout中添加这两个控件:
```
layout.addWidget(self.id_line_edit)
layout.addWidget(self.filter_button)
```
3. 添加filter_result函数来执行筛选操作:
```
def filter_result(self):
id = self.id_line_edit.text().strip()
if len(id) == 0:
QMessageBox.warning(self, '提示', '请输入员工ID')
return
db = pymysql.connect(host='39.99.214.172', user='root', password='Solotion.123', db='jj_tset')
cursor = db.cursor()
db_sql = f"SELECT * FROM table_name WHERE id = '{id}'"
cursor.execute(db_sql)
result = cursor.fetchall()
db.close()
if len(result) == 0:
QMessageBox.information(self, "提示", "没有找到符合条件的记录")
return
self.table_widget.setRowCount(0)
for row_num, row_data in enumerate(result):
self.table_widget.insertRow(row_num)
for col_num, col_data in enumerate(row_data):
self.table_widget.setItem(row_num, col_num, QTableWidgetItem(str(col_data)))
```
注意替换db_sql中的table_name为你的表名。这个函数会从数据库中查询符合条件的记录并展示在表格中。
4. 修改show_query1_result函数,在最开始添加以下代码,用于展示所有记录:
```
db = pymysql.connect(host='39.99.214.172', user='root', password='Solotion.123', db='jj_tset')
cursor = db.cursor()
db_sql = """SELECT * FROM table_name"""
cursor.execute(db_sql)
result = cursor.fetchall()
db.close()
if len(result) == 0:
QMessageBox.information(self, "提示", "今日无员工工资记录")
return
```
注意同样替换db_sql中的table_name为你的表名。这个代码块会在进入数据展示页面时展示所有记录。
通过以上修改,你就可以在数据展示页面添加筛选功能了。
