Question

我尝试为我的项目编写函数，该函数允许用户部分搜索并使用sqlite3语句根据“名称”列突出显示行/记录。但是我不知道如何使用它与SQLite3语句一起使用的功能，并匹配树视图中的行/记录。

def saerch_medicine():
 #query with sqlite3
    conn = sqlite3.connect("pharmacy.db")
    cur = conn.cursor()
    conn.commit()
    cur.execute("SELECT name FROM medicine WHERE name LIKE '%"name_column"%'")
   selections=[] 
     for i in cur:
         tree. selections[0] 
    conn.close()

bt6 = Button(root,text="Serach according column name",width=10,command=saerch)
bt6.grid(row=11,column=1,pady=10,padx=20)
e6 = Entry(root,width=20)
e6.grid(row=11,column=3,pady=10,padx=20)

假设tree的第一列是name列，然后修改saerch_medicine()（saerch应该是search吗？），如下所示：< / p>


def saerch_medicine():
    srch_name = e6.get().strip()
    if srch_name:
        conn = sqlite3.connect("pharmacy.db")
        cur = conn.cursor()
        cur.execute('SELECT name FROM medicine WHERE name LIKE "%{}%"'.format(srch_name))
        matched = [rec[0] for rec in cur]
        conn.close()
        items = [row for row in tree.get_children() if tree.item(row, 'values')[0] in matched]
        tree.selection_set(items)

但是，如果所有记录都已插入tree，我想您可以直接搜索tree：

def saerch_medicine():
    srch_name = e6.get().strip()
    if srch_name:
        rows = [row for row in tree.get_children() if srch_name in tree.item(row, 'values')[0]]
        tree.selection_set(rows)

在数据库sqlite3中查询
