代码如下。当有记录要删除时,它返回“DELETE 1”,没有时记录“DELETE 0”。但是,如果有记录,它实际上并不删除记录。粘贴到pgAdmin III中的完全相同的SQL(用%s
替换为tournament_id
)删除记录。我在木材/树木阶段。有任何想法吗?python Psycopg删除不起作用
def deletePlayers(tournamentId):
# takes tournamentId and deletes all records from tournament_player
# with that tournamentId
# but not an error if no records to delete
# check tournamentId set if not return
if tournamentId < 1:
returnStr = "ERROR - tournamentId not set"
return returnStr
DB = connect()
cur = DB.cursor()
# delete data
SQL = "DELETE from tournament_player where tournament_id = %s;"
data = (tournamentId,)
cur.execute(SQL, data)
returnStr = cur.statusmessage
DB.commit
# tidy up
cur.close
DB.close
return returnStr
非常感谢,这固定它 - 我会得到一个锂充值。 – 2015-03-02 16:38:02
