Enum AutocommitDmlMode

java.lang.Object
java.lang.Enum<AutocommitDmlMode>
com.google.cloud.spanner.connection.AutocommitDmlMode
All Implemented Interfaces:
Serializable, Comparable<AutocommitDmlMode>
public enum AutocommitDmlMode extends Enum<AutocommitDmlMode>
Enum used to define the behavior of DML statements in autocommit mode

  • Enum Constant Details

    • TRANSACTIONAL

      public static final AutocommitDmlMode TRANSACTIONAL
      TRANSACTIONAL: DML statements use a standard atomic transaction.

    • PARTITIONED_NON_ATOMIC

      public static final AutocommitDmlMode PARTITIONED_NON_ATOMIC
      PARTITIONED_NON_ATOMIC: DML statements use a Partitioned DML transaction.

    • TRANSACTIONAL_WITH_FALLBACK_TO_PARTITIONED_NON_ATOMIC

      public static final AutocommitDmlMode TRANSACTIONAL_WITH_FALLBACK_TO_PARTITIONED_NON_ATOMIC
      TRANSACTIONAL_WITH_FALLBACK_TO_PARTITIONED_NON_ATOMIC: DML statements are first executed with a standard atomic transaction. If that fails due to the mutation limit being exceeded, the statement will automatically be retried using a Partitioned DML transaction. These statements are not guaranteed to be atomic. The corresponding TransactionRetryListener methods will be invoked when a DML statement falls back to Partitioned DML.

  • Method Details

    • values

      public static AutocommitDmlMode[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static AutocommitDmlMode valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null

    • getStatementString

      public String getStatementString()
      Use this method to get the correct format for use in a SQL statement. Autocommit dml mode must be wrapped between single quotes in SQL statements: SET AUTOCOMMIT_DML_MODE='TRANSACTIONAL' This method returns the value without the single quotes.
      Returns:
      a string representation of this AutocommitDmlMode that can be used in a SQL statement.
