示例1: init_clause
# 需要导入模块: from sqlalchemy.engine import util [as 别名]
# 或者: from sqlalchemy.engine.util import _distill_params [as 别名]
def init_clause(cls, dialect, elem, multiparams, params, connection):
# partially copied from:
# sqlalchemy.engine.base.Connection:_execute_clauseelement
distilled_params = _distill_params(multiparams, params)
if distilled_params:
# note this is usually dict but we support RowProxy
# as well; but dict.keys() as an iterable is OK
keys = distilled_params[0].keys()
else:
keys = []
compiled_sql = elem.compile(
dialect=dialect, column_keys=keys,
inline=len(distilled_params) > 1,
)
conn = ConnectionAdaptor(dialect, connection, compiled_sql)
rv = cls._init_compiled(
dialect, conn, conn, compiled_sql, distilled_params)
return rv 示例2: __init__
