【问题描述】:
代码如下。有要删除的记录时返回“DELETE 1”,没有要删除的记录时返回“DELETE 0”。但是当那里有记录时,它实际上并没有删除记录。粘贴到 pgAdmin III 中的完全相同的 SQL(%s 替换为 tournament_id)会删除记录。我在木头/树木阶段。有什么想法吗?
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
