Query for multiple joins
- by Shailaja
i have 3 tables named dataset,dataelem and transformdataelem with column names as below:
main.Dataset
------------
datasetID (PK)
applicationID
main.Dataelem
-------------
dataelemID(PK)
datasetID(FK)
dataelemname
biztermID
main.Transformdataelem
----------------------
OutputdataelemID
InputdataelemID
My requirement is:
All tables are referenced.
Extract all the dataelemId rows from dataelem table where applicationID of dataset table is equal to 1044 and biztermid shud be null.
Then whatever resultant dataelemIDs from the above query should be matched with outputdataelemID of Transformdataelem table and we shud get the respective input dataelemId's.
Again with these matched inputdataelemID's we shud get the dataelemname's from datelem table.
