Sqlalchemy 核心，插入语句返回 *（所有列）

Question

I am using sqlalchemy core (query builder) to do an insert using a table definition. For example:

table.insert().values(a,b,c)

and I can make it return specific columns:

table.insert().values(a,b,c).returning(table.c.id, table.c.name)

but I am using postgres which has a RETURNING * syntax, which returns all the columns in the row. Is there a way to do that with sqlalchemy core?

Answer 1

query = table.insert().values(a,b,c).returning(literal_column('*'))

And you can access it like

for col in execute(query, stmt):
   print(col)

Answer 2

要获取所有表列，还可以执行以下查询：

table.insert().values(a,b,c).returning(table)

Answer 3

或者，您可以扩展表列：

table.insert().returning(*table.c).values(a,b,c)
