我必须将json对象传递给函数,但它不起作用:
import psycopg2
cur.execute(" SELECT mrp_sp_insert_jobdef( %s )",(json(_jobdef),) )
TypeError: 'module' object is not callable
或者:
cur.execute(" SELECT mrp_sp_insert_jobdef( % )",(json.dumps(_jobdef),) )
ValueError: unsupported format character ' ' (0x20) at index 31
答案 0 :(得分:1)
您可以使用包装器psycopg2.extras.Json(adapted, dumps=None)
,例如:
import psycopg2
from psycopg2.extras import Json
conn = psycopg2.connect("dbname=test user=postgres password=password")
cur = conn.cursor()
_jobdef = {'id': 1, 'name': 'product', 'amount': 230}
cur.execute("SELECT mrp_sp_insert_jobdef( %s )", (Json(_jobdef),) )
