Enum EPseudoTableType

Object

Enum<EPseudoTableType>

gudusoft.gsqlparser.EPseudoTableType

All Implemented Interfaces:

Serializable, Comparable<EPseudoTableType>

public enum EPseudoTableType
extends Enum<EPseudoTableType>

Vendor-neutral enum for SQL pseudo table qualifiers used in DML OUTPUT/RETURNING clauses and trigger bodies.

SQL Server: INSERTED/DELETED in OUTPUT clauses and triggers Oracle/PostgreSQL/MySQL: OLD/NEW in trigger bodies

Example (SQL Server):

 UPDATE t SET col = val
 OUTPUT inserted.col, deleted.col INTO @changes;

Method Detail

values

public static EPseudoTableType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (EPseudoTableType c : EPseudoTableType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static EPseudoTableType 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
