根因分析

查询连接了多个具有相同列名的表，且列引用未指定表名。

English

A query joins multiple tables that have a column with the same name, and the column reference is not qualified.

generic

解决方案

  1. 98% 成功率 Prefix column names with table names in the query 
    session.query(User.name, Address.city).join(Address).filter(User.name == 'Alice').all()
  2. 90% 成功率 Use column_property with explicit table qualifiers 
    from sqlalchemy import column
query = session.query(column('users.name'), column('addresses.city')).select_from(User).join(Address)

无效尝试

常见但无效的做法:

  1. Adding aliases to all columns indiscriminately 60% 失败

    Aliases may not resolve the ambiguity if the column is used in conditions.

  2. Using * in SELECT 75% 失败

    The wildcard still produces ambiguous column references in the result set.
