用于为结果添加索引的sqlite查询

我有一个包含两个参数的表：组id和名称

CREATE TABLE inf_table (group_id INTEGER NOT NULL, name TEXT NOT NULL);
INSERT INTO  inf_table(group_id, name) values (1,'AA');
INSERT INTO  inf_table(group_id, name) values (1,'BB');
INSERT INTO  inf_table(group_id, name) values (1,'AB');
INSERT INTO  inf_table(group_id, name) values (2,'AA');
INSERT INTO  inf_table(group_id, name) values (2,'BA');
INSERT INTO  inf_table(group_id, name) values (2,'AB');
INSERT INTO  inf_table(group_id, name) values (2,'BB');

我运行了一个查询，按组id然后按名称对结果排序。按组id、名称从inf\u表顺序选择*； 得到：

但是，我想为每一行添加一个索引，以显示每个组中名称的索引：

1|1|AA
2|1|AB
3|1|BB
1|2|AA
2|2|AA
3|2|BA
4|2|BB

我怎么能

您必须对同一组中的行进行计数，并且在当前名称之前有一个名称：

SELECT (SELECT COUNT(*)
        FROM inf_table AS inf2
        WHERE inf2.group_id = inf_table.group_id
          AND inf2.name    <= inf_table.name    ) AS "index",
       group_id,
       name
FROM inf_table
ORDER BY group_id,
         name

在程序中读取行时，对行进行计数可能更有效

SELECT (SELECT COUNT(*)
        FROM inf_table AS inf2
        WHERE inf2.group_id = inf_table.group_id
          AND inf2.name    <= inf_table.name    ) AS "index",
       group_id,
       name
FROM inf_table
ORDER BY group_id,
         name
