Hi folks, I need Audit multiple database tables by using creation of generic stored procedure. Could you please help me on this? Thank you.

What would be a good way to aggregate data records (or data record types) to display in a list? Appian supports the aggregation of record types in charts - I wonder if there is an easy way to display aggegration results in tables.

I encounter with the question "join performs on 3 table and each table has many rows and queries, it returns many responses". live data not required and 2 hours refresh allowed?? which option we use and why?? options:--store procedures or materialized view

In version 21.4,   Export To Excel button is exporting only 1000 records from data base view where we have more records in DB view.  And also the number of records data shown in the grid is not same as the data exported into excel. what could be the issue ? How can we resolve this issue ?

Need help to design & create records for below requirement, Each day 1 parent file and 8 child files will be loaded into DB table. Each child file will be having separate columns except foreign keys. Consider fileReferenceId and dataId are foreign keys. I have to display parent file data on landing page and provide link on dataId. Once user clicked on any of the data Id, user will be redirected to new page where records from child table needs to be fetched & displayed using dataId and fileReferenceId. My Approach:  Create entity backed record using parent table. Whenever user click on dataId  , using 'fileReferenceId ' decide which child table needs to be called from 8 tables. Using 'fileReferenceId and DataId' display returned data on interface. Could you please suggest another approach to avoid so many DB calls. Is it possible to create separate record for each child table and link in the parent record. Thanks, Hemant.

Hi, I made changes to the View (added a column to the view with datatype = text). Added the same definition to the CDT by adding new column with datatype=text. When i try to verify the datastore, it is giving me the below error The data source schema does not match the type mappings: Wrong column type in Appian.p_my_view for column fs_structure. Found: text, expected: VARCHAR(341) (APNX-2-4056-000). see below for CDT definition and view definition. There are other column exists in the view with text and it doesnt complain. any help is appreciated.

We have a solution based on record centric approach, hence all the database tables are mapped to Records, which have relationships too that vary from 3-4 per record to 10-11 on some of the records. All the interfaces are using records to display the data, recently an issue has been occurring while retrieving the data from records has become dead slow, causing time-out errors, or sometimes the interface takes forever to load. I have looked into the performance logs and server logs for any related cause and made certain performance improvement changes too but the issue still persists. The issue occurs intermittently, hence it is hard to figure out the exact cause of the issue. I'm looking out for what could be causing this and the best solution for this problem. Thanks in advance, your help is highly appreciated.

I have implemented service backed record with daily sync enabled. But the data at the source(service) gets added frequently(in minutes) and the customer want to see the updated data in Appian once its get added at the source. I have gone through documentation where I saw "Sync Changed Data". Could someone help in achieving "Sync Changed Data"? Additional Information: 1) Identifiers of the data being returned by the service are not sequential but random in ascending. (Identifier's are unknown if I need to use "Sync Record" smart service) 2) Full Data Sync takes around seven minutes. (for now there are around 180K records being returned by service, in prod it will be around 490k and will increase)

hi,  I have built a bar chart with a simple measure of SUM of time but when I put the labels I see a value like 47.9499999999999996 I have checked the issue is not with data.. I do not have that kind of data. I have a solution that I round off the the time taken, store it in another variable and use it for SUM and it works.. but I cannot individually round off the time field.. the overall data deviates a lot. All I need is to round off the above data to 47.95 .. when I see the expression generated by the MEASURE function on the chart I see Is there a way i can modify this expression so that it returns a value upto 1 or 2 decimal places.. I tried using round func in this expression but that's not working thanks much  jaideep

Trying out record centric design for the first time and I have a multiple dropdown field on the interface. Using the recordType (no data yet, just structure) as a rule input does not allow for me to specify a field as an array (like can be done with a CDT). Is there a way around this or is it as simple as 'if a multiDropdown is involved a CDT must be ctreated?

Hello, I am trying to incorporate a milestone report that links to different tasks in a process model: a!milestoneField( links: { a!processTaskLink( label: "Tasks in progress", task: 536875568 ), a!processTaskLink( label: "Tasks in progress", task: 3808 ) My problem is that the task report ID changes every time the process is run. Is there a way to query my process report for the dynamic task ID? Thanks,

Hi, We have a requirement to write over 50 000 rows daily to our MariaDB database. I want to know what is the best way to get this done. We tried using a Record Type but the data was too large for it to handle and a breaker cancelled the synchronisation. I have seen that creating Multiple node instances is not recommended as we will create an excessive connexion pool with the DB. The only solution that comes to mind is to have a subprocess that gets fed smaller batches (100 or 1000 rows) looping through the data for insertion (sequential).

How to publish data storage

Hello, me and a colleague are trying to make a database where we have a table called "students" and one called "subjects", meaning many students can take many subjects. We've been researching for a bit and the way explained in the Appian Documentation is the one explained here, it says create both the parents and child CDTs, then create a third table where you have: a primary key, a foreign key that corresponds to the first table, a foreign key that corresponds to the second table, and an index. The problem is that by doing so, you can add duplicates of each, meaning that the same student can be assigned to the same subject twice (this screenshot is the Intermediary record type): (I made 3 record types, Subjects, Students and Intermediary). That's why I wanted to ask all of you for any suggestions so that this table does not take duplicates, or if there's anything that we are doing wrong. Thank you!
