Why BULK InsertTo insert 10,000 data, if you do not bulk INSERT, then we will execute the SQL statement is 10,000 insertInsert into member (GROUP_ID, user_id, role, extend) VALUES (101, 3, NULL)Insert into member (GROUP_ID, user_id, role, extend) VALUES (101, 101, 3, NULL)Insert into member (GROUP_ID, user_id, role, extend) VALUES (

. When a transaction acquires a row lock, the transaction also needs to obtain the table lock of the table where the row of data is located. The table lock prevents conflicting DDL operations, that is, the database automatically adds an exclusive lock to the updated row and adds a sub-exclusive lock to the table where the row is located. Row locks and concurrency The following uses an example to understand the relationship between row locks and concurrency. First, create the following table and

data in parallel. When a transaction acquires a row lock, the transaction also needs to obtain the table lock of the table where the row of data is located.

routers or route switches. 3. create and apply control lists in routing mode: The create control list is similar to that of CISCO, but I feel better than CISCO in configuration mode: set qos policy-soure local; use the local policy ip access-list 101 1 permit ip 10.10.10.2 any; first, put your access address out of ip access-list 101 50 permit ip 192.168.0.0 0.0.255 any; put a segment of the address and so
