Django正在调用存储过程，事务未提交或无法执行

Question

我有一个基于django manage命令运行的代码。它有助于使用temp表和pandas库加载大量数据

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不能与pyobdc一起工作。你知道吗

但是，似乎有些代码运行了，但有些没有运行。这是调用它的过程的示例。请注意它使用合并语句。你知道吗

    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，如果更新存储过程中的变量，它将在SSMS中工作。不确定django/pyobdc是调用存储过程的原因还是我的存储过程。你知道吗

所以我错过了一些东西。但这就是解决问题的方法。已添加EXEC

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
