Python 2.7 如何使用sqlparser将SQL查询和子查询解析为python

要解析sql连接查询，请选择sub query into python。我正在使用sqlparse库。但我无法解析子查询。如何解析整个查询

e、 g:

我无法解析此

从res\u partner中选择名称，其中id=1

子查询。

不太优雅，但可以：

import sqlparse
from sqlparse.sql import Where, Comparison, Parenthesis

query = """
select
    id,fname,lname,address
from
    res_users as r
    left join
        res_partner as p
    on
        p.id=r.partner_id
where
    name = (select name from res_partner where id = 1)"""

query_tokens = sqlparse.parse(query)[0]
where = next(token for token in query_tokens.tokens if isinstance(token, Where))
condition = next(token for token in where.tokens if isinstance(token, Comparison))
subquery = next(token for token in condition.tokens if isinstance(token, Parenthesis))
print subquery

印刷品：

(select name from res_partner where id = 1)

这个库可以解析和生成SQL

(select name from res_partner where id = 1)
