sqlserver clear log

In the process of processing a full database log, it is found that sometimes the database log cannot be cleared. After experiments, it can be done in the following ways.

Use exec sp_cycle_errorlog to clear the temporary log of the SQL system itself.

dump transaction hisdb with no_log - clear log

backup log hisdb with no_log-truncate the log

backuplog hisdb to disk = 'd: \ hisdb_log.bak'

dbccshrinkfile('hisdb_log',1)

dbccshrinkfile('hisdb1_log',1)

Use the above command to clear the log.
