如何在sqlalchemy中执行LIKE查询？

Question

我用来sqlalchemy从表中获取数据。现在，从名为 的表中获取所有记录audit_trail_table正在按预期工作。

select_stmt = select([self.audit_trail_table]).where(self.audit_trail_table.c.id == int(id))
row = conn.execute(select_stmt).fetchone()

现在我希望对多个列执行LIKE查询，如下所示：

filter_query = #(some value which will work as a filter_query while fetching )records
filter_stmt = select([self.audit_trail_table]).where(self.audit_trail_table.c.first_name like '%' + filter_query + '%' or self.audit_trail_table.c.last_name like '%')

但它在 LIKE 时给出错误。我怎样才能实现这个目标？

Answer 1

您可以使用like运算符：

select([self.audit_trail_table]).where(
    self.audit_trail_table.c.first_name.like('%' + filter_query + '%') or 
    self.audit_trail_table.c.last_name.like('%abc%')
)
