Sometimes users might need to add a additional query to an already existing one that is being used to populate a value select list in the ProjectWise.

In this scenario we have a already existing query that returns a list by filtering it trough filter attribute and a form value(filter and some_attribute) it returns us a list, but we need to have a fixed amount of values added to a list that can be accessed by using another filter value.

So if original query(Select name, description from env_table_name where filter = ‘filter name’ AND some_attribute = '$EDIT#Attribute1$’ ORDER BY sort_attribute) would return:

Value 1

Value 2

Value 3

And additional
query(Select name, description from env_table_name where filter = ‘some value’ ORDER BY sort_attribute)would return:

Test1

Test2

Test3

The end result we are going for is:

Value1

Value2

Value3

Test1

Test2

Test3

How to combine two select queries to return a single list in ProjectWise attribute form:

We could use UNION operator but this is a rather highly depending on format and might not work at all so the best way to go around in this case is to use OR operator:

SELECT name, description from env_table_name where filter = ‘filter name’ AND( some_attribute = ‘$EDIT#Attribute1$’ OR filter = ‘some value’) ORDER BY sort_attribute
