Enum SqlCollation.Coercibility

java.lang.Object
  java.lang.Enum<SqlCollation.Coercibility>
      org.eigenbase.sql.SqlCollation.Coercibility

All Implemented Interfaces:

Serializable, Comparable<SqlCollation.Coercibility>

Enclosing class:

SqlCollation

public static enum SqlCollation.Coercibility
extends 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>.

Method Detail

values

public static final SqlCollation.Coercibility[] values()

Returns an array containing the constants of this enum type, in the order they're 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're declared

valueOf

public static SqlCollation.Coercibility 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
