I'd like to create a temporary table in SQLAlchemy. I can build a CREATE TABLE statement with a TEMPORARY clause by calling table._prefixes.append('TEMPORARY') against a Table object, but that's less elegant than table.select().prefix_with开发者_运维知识库() used to add a prefix to data manipulation language expressions.
Is there an equivalent to .prefix_with() for DDL?
No, prefix_with() is defined for SELECT and INSERT only. But convenient way to add prefix to CREATE TABLE statement is passing it into table definition:
t = Table(
't', metadata,
Column('id', Integer, primary_key=True),
# ...
prefixes=['TEMPORARY'],
)
加载中,请稍侯......
