If your MySQL installation supports InnoDB tables, simply add a TYPE = InnoDB definition to the table creation statement.įor example, the following code creates an InnoDB table called tcount_tbl mysql -u root -p password įor more details on InnoDB, you can click on the following link − InnoDB If your MySQL version does not have InnoDB support, ask your Internet Service Provider to build a version of MySQL with support for InnoDB table types or download and install the MySQL-Max Binary Distribution for Windows or Linux/UNIX and work with the table type in a development environment. Support for InnoDB tables requires a specific compilation parameter when compiling MySQL from the source. There are many types of tables, which support transactions, but the most popular one is InnoDB. If you plan to use transactions in your MySQL programming, then you need to create your tables in a special way. However, they are not safe and guaranteed. You cannot use transactions directly, but for certain exceptions you can. If there is any error, then issue a ROLLBACK command, otherwise issue a COMMIT command.

Issue one or more SQL commands like SELECT, INSERT, UPDATE or DELETE.Ĭheck if there is no error and everything is according to your requirement. You can execute these SQL commands in PHP by using the mysql_query() function.īegin transaction by issuing the SQL command BEGIN WORK.

When AUTOCOMMIT is set to 0, by issuing the SET AUTOCOMMIT = 0 command, the subsequent series of statements acts like a transaction and no activities are committed until an explicit COMMIT statement is issued. If AUTOCOMMIT is set to 1 (the default), then each SQL statement (within a transaction or not) is considered a complete transaction and committed by default when it finishes. You can control the behavior of a transaction by setting session variable called AUTOCOMMIT. If a failure occurs, a ROLLBACK command should be issued to return every table referenced in the transaction to its previous state. When a successful transaction is completed, the COMMIT command should be issued so that the changes to all involved tables will take effect. These two keywords Commit and Rollback are mainly used for MySQL Transactions. The SQL commands between the beginning and ending statements form the bulk of the transaction. In MySQL, the transactions begin with the statement BEGIN WORK and end with either a COMMIT or a ROLLBACK statement. Isolation − This enables transactions to operate independently on and transparent to each other.ĭurability − This ensures that the result or effect of a committed transaction persists in case of a system failure. Transactions have the following four standard properties, usually referred to by the acronym ACID −Ītomicity − This ensures that all operations within the work unit are completed successfully otherwise, the transaction is aborted at the point of failure and previous operations are rolled back to their former state.Ĭonsistency − This ensures that the database properly changes states upon a successfully committed transaction. Practically, you will club many SQL queries into a group and you will execute all of them together as a part of a transaction. If any operation within the transaction fails, the entire transaction will fail. In other words, a transaction will never be complete unless each individual operation within the group is successful. A transaction is a sequential group of database manipulation operations, which is performed as if it were one single work unit.
