Method Detail

values

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

Returns:

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

valueOf

public static SqlConformance 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

isSortByOrdinal

public boolean isSortByOrdinal()

Whether 'order by 2' is interpreted to mean 'sort by the 2nd column in the select list'.

isSortByAlias

public boolean isSortByAlias()

Whether 'order by x' is interpreted to mean 'sort by the select list item whose alias is x' even if there is a column called x.

isSortByAliasObscures

public boolean isSortByAliasObscures()

Whether "empno" is invalid in "select empno as x from emp order by empno" because the alias "x" obscures it.
