Transaction

interface Transaction : Closeable (source code)

Representation of a transaction.

Transactional code can use this interface to retrieve the backend connection, and
to programmatically trigger a commit or rollback (instead of implicit commits and rollbacks
of using Database.useTransaction).

Properties

Name	Summary
connection	`abstract val connection: Connection` The backend JDBC connection of this transaction.

Functions

Name	Summary
close	`abstract fun close(): Unit` Close the transaction and release its underlying resources (e.g. the backend connection).
commit	`abstract fun commit(): Unit` Commit the transaction.
rollback	`abstract fun rollback(): Unit` Rollback the transaction.

Extension Functions

Name	Summary
eq	`infix fun <T : Any> T.eq( expr: ColumnDeclaring<T> ): BinaryExpression<Boolean>` Equal operator, translated to `=` in SQL.
neq	`infix fun <T : Any> T.neq( expr: ColumnDeclaring<T> ): BinaryExpression<Boolean>` Not-equal operator, translated to `<>` in SQL.
notEq	`infix fun <T : Any> T.notEq( expr: ColumnDeclaring<T> ): BinaryExpression<Boolean>` Not-equal operator, translated to `<>` in SQL.
use	`fun <T : AutoCloseable?, R> T.use(block: (T) -> R): R` Execute the given block function on this resource and then close it down correctly whether an exception is thrown or not.
