“SELECT INTO”会导致 SQL Server 上的任何表锁定吗？

Question

select * 
into BCK_PH 
from purchase_history
where cast(end_dt as date) <= '2018-06-30';  

Do we get any table locks and any performance issue, if we run the above query? is there any alternative

Answer 1

The base table that is "purchase_history" will be accessible during the query execution time. But the new table "BCK_PH" only be available to access just after the query execution finished. Click for more details .
