Elephants can also drink up to 50 gallons of water a day about as much as a standard bathtub holds. Elephants are a keystone species that influence the composition of their environment while often benefiting other species.
Log Sequence Number. Every record in SQL Server transaction log has its own log sequence number or LSN. Log sequence numbers are ordered in such a way that changes related to the record with greater LSN occurred after the changes related to records with smaller LSN. Each backup that is set in SQL Server has FirstLSN and LastLSN values.
For example, Texas residents were given SSNs with the first three numbers in the range of 449-467. However, to help prevent identity theft and provide numbering flexibility, SSNs are now assigned on a random basis to new SSN recipients. Current SSN holders will not have their number affected by the new random system.
