Enum Constant Summary

Enum Constants

Enum Constant	Description
INSENSITIVE	The INSENSITIVE mode does not care the window framing without LEAD/LAG agg function, for example RANK/DENSE_RANK/PERCENT_RANK/ROW_NUMBER/NTILE.
OFFSET	The OFFSET mode does not care the window framing with LEAD/LAG agg function, see SqlLeadLagAggFunction.
RANGE	The RANGE mode allows window framing with RANGE clause.
ROW	The ROW mode allows window framing with ROW clause.

Method Detail

values

public static BatchExecOverAggregateBase.OverWindowMode[] 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 (BatchExecOverAggregateBase.OverWindowMode c : BatchExecOverAggregateBase.OverWindowMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static BatchExecOverAggregateBase.OverWindowMode 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
