public static enum SqlCollation.Coercibility extends java.lang.Enum<SqlCollation.Coercibility>
A <character value expression> consisting of a column reference has the coercibility characteristic Implicit, with collating sequence as defined when the column was created. A <character value expression> consisting of a value other than a column (e.g., a host variable or a literal) has the coercibility characteristic Coercible, with the default collation for its character repertoire. A <character value expression> simply containing a <collate clause> has the coercibility characteristic Explicit, with the collating sequence specified in the <collate clause>.

values
public static SqlCollation.Coercibility[] 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 (SqlCollation.Coercibility c : SqlCollation.Coercibility.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static SqlCollation.Coercibility valueOf(java.lang.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:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
