All Implemented Interfaces:

Serializable, Comparable<BinaryWidthSpelling>, Constable

public enum BinaryWidthSpelling
extends Enum<BinaryWidthSpelling>

How a BINARY's width is spelled where the plan names the type — SYSTEM$TYPEOF and the argument-type refusals (live-verified):

                                                   SYSTEM$TYPEOF         refusal
   DECLARED  a column, X'..', CAST(x AS BINARY(n))  BINARY(n)             BINARY(n)
   UNSIZED   TO_BINARY, CAST(x AS BINARY), DECRYPT  BINARY                BINARY(67108864)
   MAXIMUM   COALESCE(b5, TO_BINARY(s))             BINARY(67108864)      BINARY(67108864)
 

The spelling is carried beside the width a binary is held at, which it never changes.

Enum Constant Summary

Enum Constants

Enum Constant	Description
DECLARED	Sized at its own width.
MAXIMUM	Sized at the 64MB maximum: a fold that met an unsized branch after a sized one.
UNSIZED	Never sized by the plan: the result of a conversion, a cast to a bare BINARY, a SQL UDF.

Method Summary

Modifier and Type	Method	Description
BinaryWidthSpelling	meeting(BinaryWidthSpelling later)	The spelling a fold takes where a branch spelled later follows branches spelled this one.
static BinaryWidthSpelling	valueOf(String name)	Returns the enum constant of this class with the specified name.
static BinaryWidthSpelling[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

DECLARED

public static final BinaryWidthSpelling DECLARED

Sized at its own width.

UNSIZED

public static final BinaryWidthSpelling UNSIZED

Never sized by the plan: the result of a conversion, a cast to a bare BINARY, a SQL UDF.

MAXIMUM

public static final BinaryWidthSpelling MAXIMUM

Sized at the 64MB maximum: a fold that met an unsized branch after a sized one.

Method Details

values

public static BinaryWidthSpelling[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static BinaryWidthSpelling valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

meeting

public BinaryWidthSpelling meeting(BinaryWidthSpelling later)

The spelling a fold takes where a branch spelled later follows branches spelled this one. The lead decides: an unsized lead keeps the fold unsized, and a sized lead meeting anything unsized takes it to the maximum — live, IFF(c, TO_BINARY(s), X'00') is bare BINARY while IFF(c, X'00', TO_BINARY(s)) is BINARY(67108864).

Parameters:

later - the following branch's spelling

Returns:

the folded spelling
