It is often the case that developers new to databases will try to perform large data modifications without batching. When this happens in most cases the modification will fail with the error of the transaction log being full after you are presented with the message The transaction log in the database
To correct this it is good practice to perform your database modifications in batches, and upon each iteration of the batch to clear your log transaction file. The dump tran command notifies Sybase that you want to clear the transaction log of a database and with which options. In these cases you simply want to clear it without backing up the log to a file so you would use the with turncate_only option.
