Question

我有此代码基于django manage命令运行。它有助于使用临时表和熊猫库加载一堆数据

def MergeAce(table=None,user=1,db_instance=None):
    if db_instance:
        db = db_instance
    else:
        return False

    with connections[db].cursor() as cursor:
        result = cursor.execute(f"spMergeAce {user} , '{table}'")
        cursor.commit()
    return result

我知道我没有正确调用参数，并且当前 callproc 不适用于 pyobdc 。

但是，似乎某些代码在运行，但有些则没有。这是其调用过程的示例。请使用合并语句来记录它。

    UPDATE TARGET
    set

        TARGET.updatedate = getdate(),
        TARGET.[Inactive] = 1,
        TARGET.[InactiveDate] = getdate()
    from [dbo].[ACE] AS TARGET
    left join [dbo].['+ @table + '] AS SOURCE on TARGET.aclid = SOURCE.aclid and TARGET.hash = SOURCE.hash and TARGET.configline = SOURCE.configline
    where SOURCE.id is null AND TARGET.[Inactive] <> 1 AND TARGET.aclid in (
        SELECT distinct ace2.aclid from ace ace2 join acl on acl.id = ace2.aclid where acl.zoneid in (SELECT distinct zoneid from [dbo].['+ @table + '])); 

    drop table [dbo].['+ @table + '];
    '


    exec sp_executesql @query
    COMMIT
END

此外，如果我更新存储过程中的变量，则它可以在SSMS中工作。不知道django / pyobdc是调用存储过程的原因还是我的存储过程。

所以我错过了几件事。但这是解决问题的方法。 EXEC已添加


def MergeAcl(table=None,user=1,db_instance=None):
    if db_instance:
        db = db_instance
    else:
        return False
    with connections[db].cursor() as cursor:
        try:
            cursor.execute(f"EXEC [dbo].spMergeAcl @user = {user}, @table = [{table}]")
        except Exception as e:
            logger.error(e)
            return False
        rows = cursor.fetchall()
        while rows:
            logger.debug(rows) # not needed, just used for debugging
            if cursor.nextset():
                rows = cursor.fetchall()
            else:
                rows = None
    return True

Django调用存储过程，事务未提交或执行失败
