Examples with TransactionAccessMode io.trino.sql.tree.TransactionAccessMode used on opensource projects

Example 1 with TransactionAccessMode

use of io.trino.sql.tree.TransactionAccessMode in project trino by trinodb.

the class TestStartTransactionTask method testStartTransactionTooManyAccessModes.

@Test
public void testStartTransactionTooManyAccessModes() {
    Session session = sessionBuilder().setClientTransactionSupport().build();
    TransactionManager transactionManager = createTestTransactionManager();
    QueryStateMachine stateMachine = createQueryStateMachine("START TRANSACTION", session, transactionManager);
    assertFalse(stateMachine.getSession().getTransactionId().isPresent());
    assertTrinoExceptionThrownBy(() -> getFutureValue(new StartTransactionTask(transactionManager).execute(new StartTransaction(ImmutableList.of(new TransactionAccessMode(true), new TransactionAccessMode(true))), stateMachine, emptyList(), WarningCollector.NOOP))).hasErrorCode(SYNTAX_ERROR);
    assertTrue(transactionManager.getAllTransactionInfos().isEmpty());
    assertFalse(stateMachine.getQueryInfo(Optional.empty()).isClearTransactionId());
    assertFalse(stateMachine.getQueryInfo(Optional.empty()).getStartedTransactionId().isPresent());
}

Example 2 with TransactionAccessMode

use of io.trino.sql.tree.TransactionAccessMode in project trino by trinodb.

the class TestStartTransactionTask method testStartTransactionExplicitModes.

@Test
public void testStartTransactionExplicitModes() {
    Session session = sessionBuilder().setClientTransactionSupport().build();
    TransactionManager transactionManager = createTestTransactionManager();
    QueryStateMachine stateMachine = createQueryStateMachine("START TRANSACTION", session, transactionManager);
    assertFalse(stateMachine.getSession().getTransactionId().isPresent());
    getFutureValue(new StartTransactionTask(transactionManager).execute(new StartTransaction(ImmutableList.of(new Isolation(Isolation.Level.SERIALIZABLE), new TransactionAccessMode(true))), stateMachine, emptyList(), WarningCollector.NOOP));
    assertFalse(stateMachine.getQueryInfo(Optional.empty()).isClearTransactionId());
    assertTrue(stateMachine.getQueryInfo(Optional.empty()).getStartedTransactionId().isPresent());
    assertEquals(transactionManager.getAllTransactionInfos().size(), 1);
    TransactionInfo transactionInfo = transactionManager.getTransactionInfo(stateMachine.getQueryInfo(Optional.empty()).getStartedTransactionId().get());
    assertEquals(transactionInfo.getIsolationLevel(), IsolationLevel.SERIALIZABLE);
    assertTrue(transactionInfo.isReadOnly());
    assertFalse(transactionInfo.isAutoCommitContext());
}

Example 3 with TransactionAccessMode
