Insert values into table at the end of the query

Insert values into table at the end of the query

In my query im using for loop. Each and every time when for loop is
executed, at the end some values has to be inserted into table. This is
time consuming because for loop has many records. Due to this each and
every time when for loop is executed, insertion is happening. Is there any
other way to perform insertion at the end after the for loop is executed.
