这个问题在这里已经有了答案:
在非递归过程中超过递归限制(1个答案)
两年前关门了。
当我试图调用c#中的存储过程时。这是回报:
例程delete\u medikalislem超过递归限制0(由max\u sp\u recursion\u depth变量设置)
删除medikalislem程序:
DELETE FROM medikal WHERE islem_id = p_id;
存储参数:name:p\u id,type:varchar,length:25
using (MySqlConnection connect = new MySqlConnection(connectionString))
{
using (MySqlCommand cmd = new MySqlCommand(mw.db_name+ ".delete_medikalislem", connect))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("p_id", mw.medikalislem[0]);
connect.Open();
cmd.ExecuteNonQuery();
connect.Close();
}
}
i使用后删除触发器:
BEGIN
DECLARE tl_ integer default 0;
DECLARE usd_ integer default 0;
DECLARE eur_ integer default 0;
DECLARE gbp_ integer default 0;
DECLARE toplam_ integer default 0;
SELECT tl, usd, eur, gbp INTO tl_, usd_, eur_, gbp_ FROM medikalfirmalar WHERE isim = OLD.medikal_isim;
DELETE FROM medikal_caritahsilat WHERE islem_id = OLD.islem_id;
IF (OLD.birim='TL') THEN
SET toplam_= tl_ - OLD.tutar;
UPDATE medikalfirmalar SET tl = toplam_ WHERE isim = OLD.medikal_isim;
END IF;
IF (OLD.birim='USD') THEN
SET toplam_= usd_ - OLD.tutar;
UPDATE medikalfirmalar SET usd = toplam_ WHERE isim = OLD.medikal_isim;
END IF;
IF (OLD.birim='EUR') THEN
SET toplam_= eur_ - OLD.tutar;
UPDATE medikalfirmalar SET eur = toplam_ WHERE isim = OLD.medikal_isim;
END IF;
IF (OLD.birim='GBP') THEN
SET toplam_= gbp_ - OLD.tutar;
UPDATE medikalfirmalar SET gbp = toplam_ WHERE isim = OLD.medikal_isim;
END IF;
END
我该怎么修?

它只是sql在抱怨递归性。
你必须明确地告诉它递归可以有多少层。
在程序开始时添加以下内容:
