在vb.net中获取最近更新的行mysql的ID

Question

I tried using SELECT LAST_INSERT_ID() to get last id updated but it gives me zero. please help me

Answer 1

If you're using Connector/.NET, you will find that the MySqlCommand object has a LastInsertedId property. You can use retrieve that property value immediately after your INSERT query, and you don't have to execute another query.

If you're not doing INSERT operations, you won't get any LAST_INSERTED_ID() value. If all you're doing is UPDATE querys, forget about LAST_INSERTED_ID() .

Answer 2

add your table a new column with DATETIME type. and choose on update CURRENT timestamp option from attribute section. In this way whenever an update occurs in the column your database will update this row automaticly. Then all yo need to do is writing your SQL command from your script.

SELECT id fROM table  ORDER BY name_of_datetime_column DESC LIMIT 1

will return only one column which is last updated one
