All Implemented Interfaces:

Serializable, Comparable<SqlTableLike.MergingStrategy>

Enclosing class:

SqlTableLike

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

A strategy that describes how the features of the parent source table should be merged with the features of the newly created table.

• EXCLUDING - does not include the given feature of the source table
• INCLUDING - includes feature of the source table, fails on duplicate entries, e.g. if an option with the same key exists in both tables.
• OVERWRITING - includes feature of the source table, overwrites duplicate entries of the source table with properties of the new table, e.g. if an option with the same key exists in both tables, the one from the current statement will be used.
