generally require a lot of memory, so called expensive)Need to request memory, at the same time they can run out of computer memory.To prevent this from happening, SQL Server uses something called a " resource semaphore ." This will ensure that the total memory allocation of the query being executed will not exceedThe sum of memory in the current computer. When the total memory allocation is running out of

Since data can be ubiquitous, developers naturally want to write a query to join as much data as possible regardless of whether it is local or remote. As a result, the use of the linked server has come into being, but the misuse and unreasonable use of
