[英]How to Optimize the SQL Query in Jooq to return Table Object
I am using below code run a query with Join 我在下面的代码中使用Join运行查询
@Transactional
public Result<Record> getFolderFeeList(int argFolderRSN, String argOrderBy) {
Transaction transaction = Transaction.current();
// List<ValidAccountFeeRow> validSiteOptionList = transaction.daos().getValidAccountFeeDao().findAll();
SelectQuery<Record> selectQuery = transaction.selectQuery();
selectQuery.addSelect(
Routines.fFoldername(argFolderRSN).as("FolderName"),
AccountBillFee.ACCOUNT_BILL_FEE.FOLDER_RSN,
AccountBillFee.ACCOUNT_BILL_FEE.PARENT_ACCOUNT_BILL_FEE_RSN,
AccountBillFee.ACCOUNT_BILL_FEE.FEE_CODE,
AccountBillFee.ACCOUNT_BILL_FEE.PROCESS_RSN,
AccountBillFee.ACCOUNT_BILL_FEE.SECURITY_CODE,
AccountBillFee.ACCOUNT_BILL_FEE.FEE_AMOUNT,
Routines.fGetpaidinfullflag(AccountBillFee.ACCOUNT_BILL_FEE.BILL_NUMBER, AccountBill.ACCOUNT_BILL.PAYMENT_OPTION,
AccountBillFee.ACCOUNT_BILL_FEE.FEE_LEFT.cast(Double.class), AccountBill.ACCOUNT_BILL.PAID_IN_FULL_FLAG.cast(String.class))
.as("PaidInFullFlag"), AccountBillFee.ACCOUNT_BILL_FEE.MANDATORY_FLAG, AccountBill.ACCOUNT_BILL.DUE_DATE,
AccountBillFee.ACCOUNT_BILL_FEE.BILL_NUMBER, AccountBillFee.ACCOUNT_BILL_FEE.ACCOUNT_BILL_FEE_RSN,
AccountBillFee.ACCOUNT_BILL_FEE.FEE_COMMENT);
selectQuery.addFrom(AccountBillFee.ACCOUNT_BILL_FEE);
selectQuery.addJoin(AccountBill.ACCOUNT_BILL, JoinType.LEFT_OUTER_JOIN,
AccountBill.ACCOUNT_BILL.BILL_NUMBER.eq(AccountBillFee.ACCOUNT_BILL_FEE.BILL_NUMBER));
selectQuery.addJoin(ValidAccountFee.VALID_ACCOUNT_FEE,
AccountBillFee.ACCOUNT_BILL_FEE.FEE_CODE.eq(ValidAccountFee.VALID_ACCOUNT_FEE.FEE_CODE));
selectQuery.addConditions(AccountBillFee.ACCOUNT_BILL_FEE.FOLDER_RSN.eq(argFolderRSN));
if (argOrderBy == null) {
selectQuery.addOrderBy(AccountBillFee.ACCOUNT_BILL_FEE.FOLDER_RSN.asc(), AccountBillFee.ACCOUNT_BILL_FEE.BILL_NUMBER.asc(),
AccountBillFee.ACCOUNT_BILL_FEE.FEE_CODE.asc());
} else {
// To Do selectQuery.addOrderBy(argOrderBy);
}
Result<Record> result = selectQuery.fetch();
return result;
}
Now is it pssible somehow this query will return me AccountBillFee
table whole object as well as functions values? 现在是不是这样查询将返回我的
AccountBillFee
表整个对象以及函数值? As i saw in JOOQ if i am creating a object by my self its always inserting a new record rather than updating it. 正如我在JOOQ中看到的那样,如果我自己创建一个对象,它总是插入一条新记录而不是更新它。
You can add all of AccountBillFee
's columns to your SELECT
statement in one go: 您可以一次性将所有
AccountBillFee
列添加到SELECT
语句中:
selectQuery.addSelect(AccountBillFee.fields());
Since you want to store the fetched (enriched) AccountBillFeeRecord
record again to the database, I suggest you try something like: 由于您希望将获取的(丰富的)
AccountBillFeeRecord
记录再次存储到数据库,我建议您尝试以下方法:
// This is the "weakly typed", generic record with the additional columns
Record record =
DSL.using(configuration)
.select(...)
.from(ACCOUNT_BILL_FEE)
.fetchOne();
// This is one way to transform the above record into a
// "table-typed" record that you can store
AccountBillFeeRecord r1 = record.into(ACCOUNT_BILL_FEE);
r1.update();
Thanks to @Lukas here is Solution which i was looking 感谢@Lukas,这是我正在寻找的解决方案
@Transactional
public Result<Record> getFolderFeeList(int argFolderRSN, String argOrderBy) {

// List<ValidAccountFeeRow> validSiteOptionList transaction.daos().getValidAccountFeeDao().findAll();

selectQuery.addSelect(Routines.fFoldername(argFolderRSN).as("FolderName"),
Routines.fGetpaidinfullflag(AccountBillFee.ACCOUNT_BILL_FEE.BILL_NUMBER, AccountBill.ACCOUNT_BILL.PAYMENT_OPTION,
AccountBillFee.ACCOUNT_BILL_FEE.FEE_LEFT.cast(Double.class), AccountBill.ACCOUNT_BILL.PAID_IN_FULL_FLAG.cast(String.class))
.as("PaidInFullFlag"),AccountBill.ACCOUNT_BILL.DUE_DATE);
selectQuery.addSelect(AccountBillFee.ACCOUNT_BILL_FEE.fields());
selectQuery.addFrom(AccountBillFee.ACCOUNT_BILL_FEE);
selectQuery.addJoin(AccountBill.ACCOUNT_BILL, JoinType.LEFT_OUTER_JOIN,
AccountBill.ACCOUNT_BILL.BILL_NUMBER.eq(AccountBillFee.ACCOUNT_BILL_FEE.BILL_NUMBER));
selectQuery.addJoin(ValidAccountFee.VALID_ACCOUNT_FEE,
AccountBillFee.ACCOUNT_BILL_FEE.FEE_CODE.eq(ValidAccountFee.VALID_ACCOUNT_FEE.FEE_CODE));

} else {
// To Do selectQuery.addOrderBy(argOrderBy);
}
Result<Record> result = selectQuery.fetch();
for(Record record : result){
AccountBillFeeRecord r1 = record.into(AccountBillFee.ACCOUNT_BILL_FEE);
System.out.println(record.getValue("FolderName"));
}
return result;
