python - SQLAlchemy中模糊查询，如何like多个关键字

Question

比如需要找出u_name中既有“三”又有“猫”的记录：
SQL原生语句如下：

SELECT * FROM [user] WHERE u_name LIKE '%三%' AND u_name LIKE '%猫%'

请问这个如何在 SQLAlchemy 中实现呢

Answer 1

from sqlalchemy import and_


words = ['%三%', '%猫%']
rule = and_(*[table.u_name.like(w) for w in words])
table.query.filter(rule)

Answer 2

DBSession().query(user).filter(user.u_name.like('%三%')).filter(user.u_name.like('%猫%'))

Or you can use and_()

DBSession().query(user).filter(and_(user.u_name.like('%三%'), user.u_name.like('%猫%')))
