I'm currently working on a functionality that involves view with huge dataset in Appian and I am planning to replace it with record relationship. I have a situation where I'm using a left join with a table and implementing a self-join with three conditions using the AND operator.
Here's the view that I want to replace.
SELECT `snapFrom`.`id` AS `id`, `snapFrom`.`material` AS `material`, CAST( `snapFrom`.`FCFinalTotal` AS DOUBLE ) AS `FCFinalTotalFrom`, CAST(`snapTo`.`FCFinalTotal` AS DOUBLE) AS `FCFinalTotalTo`, `snapFrom`.`snapshot` AS `snapFrom`, `snapTo`.`snapshot` AS `snapTo`, `snapTo`.`FCFinalTotal` - `snapFrom`.`FCFinalTotal` AS `diffValue`, CONCAT( SUBSTRING_INDEX(`snapFrom`.`calWeek`, '.', -1), '.', SUBSTRING_INDEX(`snapFrom`.`calWeek`, '.', 1) ) AS `calWeek`, `m`.`basecode` AS `baseCode`FROM ( ( `Appian`.`SOE_STAGING_FORECAST_WEEKLY` `snapFrom` LEFT JOIN `Appian`.`SOE_STAGING_FORECAST_WEEKLY` `snapTo` ON ( `snapFrom`.`calWeek` = `snapTo`.`calWeek` AND `snapFrom`.`material` = `snapTo`.`material` AND `snapFrom`.`companyCode` = `snapTo`.`companyCode` ) ) LEFT JOIN `Appian`.`SOE_MaterialMasterData` `m` ON ( `m`.`material` = `snapFrom`.`material` AND `m`.`companyCode` = `snapFrom`.`companyCode` ) )WHERE `m`.`basecode` IS NOT NULL
I have created three records and established the relationship, but i am struggling to add join condition, can someone advice how we can add these join conditions.

I am pretty uncertain, what you mean by "

Records have no real joins. you can adress other data through foreign keys perhaps this page will help you more there.https://docs.appian.com/suite/help/23.4/data-modeling-with-appian-records.html
