sql 语句 批量删除指定id

Posted 2023-04-13

a 表 b 字段里面只要是包含 .abc 的 就删除整条id纪录

例如b字段里面有365.abc 、468.abc ..........的id 等 就删除这条id
这些语句我用过了 没有作用 我是菜鸟谢谢大家

删除整条记录
delete from a where b like \'%.abc\'
只是清空含有.ACB的B字段:
update a set b = null where b like \'%.abc\' 参考技术A delect from a where b like '%.abc%' 参考技术B delete from a where b like '%.abc' 参考技术C delete a where b like '%abc'

批量执行SQL语句，进行删除，插入或者更改。

private bool ExecuteTransaction(List<string> list)
    {
        using (SqlConnection connection = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["LocalConnectionString"].ToString()))
        {
            SqlCommand command = new SqlCommand();
            SqlTransaction transaction = null;
            try
            {
                connection.Open();
                transaction = connection.BeginTransaction();
                command.Connection = connection;
                command.Transaction = transaction;

                for (int i = 0; i < list.Count; i++)
                {
                    command.CommandText = list[i];
                    command.ExecuteNonQuery();
                }

                transaction.Commit();
                connection.Close();
                return true;
            }
            catch
            {
                transaction.Rollback();
                connection.Close();
                return false;
            }
        }
    }

list是要执行的SQL语句。
