NAME

       rollback-transaction -  (database)

PURPOSE

       Rollbacks a SQL transaction.

SYNTAX

           rollback-transaction [ @<database> ] \
               [ on-error-continue | on-error-exit ] \
               [ error <error> ] [ error-text <error text> ] \
               [ options <options> ]

DESCRIPTION

       rollback-transaction will roll back a transaction started with begin-transaction.

       <options> (in "options" clause) is any additional options to send to database you wish to supply for this
       functionality.

       Once you start a transaction with begin-transaction, you must either commit it with commit-transaction or
       rollback  with  rollback-transaction.  If  you  do neither, your transaction will be rolled back once the
       request has completed and your program will stop with  an  error  message.  This  is  because  opening  a
       transaction and leaving without committing or a rollback is a bug in your program.

       You  must  use  begin-transaction,  commit-transaction  and  rollback-transaction instead of calling this
       functionality through run-query.

       DATABASE

       <database> is specified in "@" clause and is the name  of  the  database-config-file.  If  omitted,  your
       program must use exactly one database (see --db option in gg).

       ERROR HANDLING

       The  error  code  is  available  in  <error>  variable  in  "error"  clause  - this code is always "0" if
       successful. The <error> code may or may not be a number but is always returned as a string value. In case
       of error, error text is available in "error-text" clause in <error text> string.

       "on-error-continue" clause specifies that request processing will continue in case of an  error,  whereas
       "on-error-exit"  clause  specifies  that it will exit. This setting overrides database-level db-error for
       this specific statement only. If you use "on-error-continue", be sure to check the error code.

       Note that if database connection was lost, and could not be reestablished, the  request  will  error  out
       (see error-handling).

EXAMPLES

           begin-transaction @mydb
           run-query @mydb="insert into employee (name, dateOfHire) values ('Terry', now())"
           run-query @mydb="insert into payroll (name, salary) values ('Terry', 100000)"
           rollback-transaction @mydb
