All Implemented Interfaces:

Serializable, Comparable<DdlInTransactionMode>

public enum DdlInTransactionMode
extends Enum<DdlInTransactionMode>

Enum used for setting the behavior of DDL in read/write transactions.

Enum Constant Summary

Enum Constants

Enum Constant	Description
ALLOW_IN_EMPTY_TRANSACTION	DDL statements in an empty transaction are allowed.
AUTO_COMMIT_TRANSACTION	DDL statements automatically cause the current transaction to be committed and the DDL statement is subsequently executed without a transaction.
FAIL	All DDL statements in a read/write transaction fail.

Method Summary

Modifier and Type	Method	Description
static DdlInTransactionMode	valueOf(String name)	Returns the enum constant of this type with the specified name.

Enum Constant Details

FAIL

public static final DdlInTransactionMode FAIL

All DDL statements in a read/write transaction fail.

ALLOW_IN_EMPTY_TRANSACTION

public static final DdlInTransactionMode ALLOW_IN_EMPTY_TRANSACTION

DDL statements in an empty transaction are allowed. That is; if the connection is in AutoCommit=false mode and no other statement has been executed, then executing a DDL statement or a DDL batch is allowed.

AUTO_COMMIT_TRANSACTION

public static final DdlInTransactionMode AUTO_COMMIT_TRANSACTION

DDL statements automatically cause the current transaction to be committed and the DDL statement is subsequently executed without a transaction. This is equal to how MySQL and Oracle behave.

Method Details

values

public static DdlInTransactionMode[] 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 DdlInTransactionMode 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
