what is difference between commit and rollback.?
Answer Posted / malli.gontla
suppose u have one table which is in database. The table
contains some records. U want to modify one record of table.
after modification, u don't want that new values for
the record. just u use rollback command. previous values are
placed in database.
Example:
Case 1: Roll Back
sno name palce
1 abc hyderabad
2 xyz bangalore.
This is the table and it contains some records.
Suppose if u want change the 2nd record, means palce
is changed to chennai.
After modification:
sno name palce
1 abc hyderabad
2 xyz Chennai.
Suppose if u want old values, means u don't want new
values. At that time u use roll back command
After useing rollback:
sno name palce
1 abc hyderabad
2 xyz bangalore.
after using roll back, the records are comes like
above(original records)
Case 2: Commit
sno name palce
1 abc hyderabad
2 xyz bangalore.
This is the table and it contains some records.
Suppose if u want change the 2nd record, means palce
is changed to chennai.
After modification:
sno name palce
1 abc hyderabad
2 xyz Chennai.
After useing commit:
sno name palce
1 abc hyderabad
2 xyz Chennai.
after using commit, the table is finilased.u can't get
old values by uisng roll back.
Once if u use commit,u can't get old values for using of
rollback. Before commit, u can get old values for rollback.
