Example 1 with DeleteStatement

use of org.hibernate.hql.internal.ast.tree.DeleteStatement in project hibernate-orm by hibernate.

the class LocalTemporaryTableBulkIdStrategy method buildDeleteHandler.

@Override
public DeleteHandler buildDeleteHandler(SessionFactoryImplementor factory, HqlSqlWalker walker) {
    final DeleteStatement updateStatement = (DeleteStatement) walker.getAST();
    final FromElement fromElement = updateStatement.getFromClause().getFromElement();
    final Queryable targetedPersister = fromElement.getQueryable();
    final IdTableInfoImpl tableInfo = getIdTableInfo(targetedPersister);
    return new TableBasedDeleteHandlerImpl(factory, walker, tableInfo) {

        @Override
        protected void prepareForUse(Queryable persister, SharedSessionContractImplementor session) {
            Helper.INSTANCE.createTempTable(tableInfo, ddlTransactionHandling, session);
        }

        @Override
        protected void releaseFromUse(Queryable persister, SharedSessionContractImplementor session) {
            Helper.INSTANCE.releaseTempTable(tableInfo, afterUseAction, ddlTransactionHandling, session);
        }
    };
}
