Rows that are inserted into a heap as the result of an insert action in a MERGE statement may also be minimally logged.Unlike the BULK INSERT statement, which holds a less restrictive Bulk Update (BU) lock, INSERT INTO … SELECT with the TABLOCK hint holds an exclusive (X) lock on the...
insert into t select * from temp_t; drop table temp_t; 1. 2. 3. 4. Insert唯一键冲突 对于有唯一键的表,插入数据时出现唯一性冲突比较常见, 这个例子在rc,rr下执行,session b都会进入block状态。 Session a在执行insert 发生唯一性冲突的时候,在冲突的索引上加了锁,一个next-key lock是由它的右边...

If this number is high, prefetchers are causing unnecessary I/O by reading pages into the buffer pool that will not be used. uow_client_idle_wait_time - Client idle time within a unit of work monitor element Indicates the time spent idle within a unit of work (UOW). The value is giv...
In order to keep the program memory saved, the compiler didn't allow us to "move" the array elements into the insert method because the array might be referenced in other parts of the program. So what we can do is to pass in a copy (duplicate) of an array element. Now it should ...
