枚举 SqlTableLike.FeatureOption

java.lang.Object

java.lang.Enum<SqlTableLike.FeatureOption>

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

所有已实现的接口:

Serializable, Comparable<SqlTableLike.FeatureOption>

封闭类:

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
 )

valueOf

public static SqlTableLike.FeatureOption valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
