Enum SqlTableLike.FeatureOption

java.lang.Object

java.lang.Enum<SqlTableLike.FeatureOption>

org.apache.flink.sql.parser.ddl.SqlTableLike.FeatureOption

All Implemented Interfaces:

Serializable, Comparable<SqlTableLike.FeatureOption>

Enclosing class:

SqlTableLike

public static enum SqlTableLike.FeatureOption
extends Enum<SqlTableLike.FeatureOption>

A feature of a table descriptor that will be merged into the new table. The way how a certain feature will be merged into the final descriptor is controlled with SqlTableLike.MergingStrategy.

• ALL - a shortcut to change the default merging strategy if none provided
• CONSTRAINTS - constraints such as primary and unique keys
• GENERATED - computed columns
• METADATA - metadata columns
• WATERMARKS - watermark declarations
• PARTITIONS - partition of the tables
• OPTIONS - connector options that describe connector and format properties

Example:

 LIKE `sourceTable` (
   INCLUDING ALL
   OVERWRITING OPTIONS
   EXCLUDING PARTITIONS
 )
 

is equivalent to:

 LIKE `sourceTable` (
   INCLUDING GENERATED
   INCLUDING CONSTRAINTS
   OVERWRITING OPTIONS
   EXCLUDING PARTITIONS
 )

Method Detail

values

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

Returns:

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

valueOf

public static SqlTableLike.FeatureOption 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
