SQLite 原始查询出现问题！
我正在尝试在 SQLite 中执行原始查询。
我想从一个表中选择所有 id 等于另一个表中的另一列的内容，但无法使其正常工作。
我一直在尝试执行的查询处于当前状态：
"SELECT * FROM " + table1 + " WHERE " +
id + " EQUALS " + FriendsIntId +
" FROM " + table2
这里显然有问题，有人可以向我指出吗？
I'm trying to do a raw query in SQLite.
I want to select all from one table where id equals another column from another table, but can't get it to work properly.
The query I've been trying to do is in it's current state:
"SELECT * FROM " + table1 + " WHERE " +
id + " EQUALS " + FriendsIntId +
" FROM " + table2
There is obviously something wrong here, can someone point it out to me?

=代替。多个
FROM子句没有任何意义。阅读有关选择的 SQLite SQL 语法 文档。也许你想要一个子选择：?
EQUALSkeyword does not exist in SQLite. Use=instead.Multiple
FROMclauses have no meaning. Read the SQLite SQL syntax documentation on selects. Maybe you want a subselect:?
