Annotation Type SQLInsert


  • @Target({TYPE,FIELD,METHOD})
    @Retention(RUNTIME)
    @Repeatable(SQLInserts.class)
    public @interface SQLInsert
    Specifies a custom SQL DML statement to be used in place of the default SQL generated by Hibernate when an entity or collection row is inserted in the database.

    The given SQL statement must have exactly the number of JDBC ? parameters that Hibernate expects, that is, one for each column mapped by the entity, in the exact order Hibernate expects. In particular, the primary key columns must come last.

    If a column should not be written as part of the insert statement, and has no corresponding JDBC parameter in the custom SQL, it must be mapped using insertable=false.

    A custom SQL insert statement might assign a value to a mapped column as it is written. In this case, the corresponding property of the entity remains unassigned after the insert is executed unless @Generated is specified, forcing Hibernate to reread the state of the entity after each insert.

    Similarly, a custom insert statement might transform a mapped column value as it is written. In this case, the state of the entity held in memory loses synchronization with the database after the insert is executed unless @Generated(writable=true) is specified, again forcing Hibernate to reread the state of the entity after each insert.

    If an entity has secondary tables, it may have a @SQLInsert annotation for each secondary table. The table() member must specify the name of the secondary table.
