QUESTION
I could not get the a nested logic to work. I need to combined data from 2 table and return it to the request. I do not want a join table as I need to return an individual record from tableA first then combine with tableB record before it is returned. Below is my simplified code

QUESTION
I am loading 2 large datasets into two separate HashMaps, sequentially. (The datasets are serialized into many Record objects, depicted below). The HashMaps are represented like so, with the key as the id of the Record:
...ANSWER
Answered 2021-Apr-29 at 16:59If the records are 'small enough' then I would not bother trying anything fancy. For large records, the easiest way seems to be to do what you're doing.
QUESTION
I have for example this dataset:
...ANSWER
Answered 2021-Mar-22 at 15:05You could take a closure over the wanted order and check the value if finite then return the delta or treat the values as string.
Inside sorting function iterate as long as the return value is falsy and take this value as return value for sorting.
QUESTION
how can I discard changes after Exception? I want to save recordB even when recordA failed to save.
...ANSWER
Answered 2021-Jan-28 at 03:44Can not be done in same transaction.
1: need to set globalRollbackOnParticipationFailure = true
2: start an new transaction with proper propagation, do everything and rollback within that transaction
QUESTION
I am using MultiRecordEngine() to read a delimited .txt file with no header and different type of records. The first two character of any record is the identifier which I am using to identify the type of the record.
The problem I am encountering is that in RecordB(see sample model below), I have a field which contains multiple values delimited with the same delimiter being used in the file. And also the field length is not fixed, it's length depends on the number of values in it. for e.g. FieldB-0000-1111-2222-3333-FieldD where 0000-1111-2222-3333 will need to be read in FieldC.
Note: FieldB contains an integer which denoted the amount of values that will be present in FieldC
I am using MultiRecordEngine() to read the file and map the records to my models for the different type of records.
A sample that looks close to what I have:
1 sample model
...ANSWER
Answered 2020-Dec-24 at 14:02I found a workaround. I'm using the model below to read only the record I know that contains the delimited field and splitting the values later and getting them by index.

It was supposed to be straightforward... I've broken down my problem to the barest, minimum code to reproduce my issue
First define a type with the general shape of all records

QUESTION
I'm trying to convert an sap iDoc to another xml file with a BizTalk map written in xslt. The problem is I need to group nodes based on a value that we can find in a specific subnode.
Muenchian grouping (I use XSLT 1.0) seems to be the solution but I can't find out how to make it works as I need to group on subnode value.

QUESTION
I'm developing a procedure and stopped at the step to validate a field separated by commas.
I need to validate that in this field there are two records separated by commas, if it exists, update the field by removing the entry record and keeping the other one. If there are more than 2 records, check which was the input record and validate if it is on the left or right side of the comma to perform the field update and keep the other records there.
I will demonstrate the field below:
...ANSWER
Answered 2020-Mar-09 at 14:20I don't understand what you're trying to do with your code, since you didn't post before/after example data. And how are you calling this procedure?
But this should answer your question well enough for you to figure out the rest.

QUESTION
Table A and Table B consists of three fields like pr_name,amount,date.
...ANSWER
Answered 2017-Nov-25 at 17:30There is no way to get the month name from sqlite using strftime so we will have to translate 1, 2, 3 ... into month names using a case statement. To be sure we get all months even if there are no data for a particular month, we can just generate numers 1 to 12 with rowid. For this use any table which has at least 12 rows. Then with subqueries we can get the desired summary data for these months:
