Custom Tag Search
« on: March 14, 2018, 08:33:59 am »
I tried the following search in the SQL scratch pad, and it works correctly.

select as Name
from (t_object c
inner join t_objectproperties op on op.Object_ID = c.Object_ID)
where op.Property = 'MyTagName' and op.Value = 'Yes'

but i want to use this same search to create a TimeSeriesChart, but when i paste the code in, and test the query, it pops up with

"The multi-part identifier "t_object.Package_ID" could not be bound"

Any ideas what I'm doing wrong?

Are you sure its the same query that's causing this eror?  I have similar queries in my charts (SQL Server) and they seem to work fine.

may be this thread could help.

I suspect what's happened is that you have also selected a package or branch to limit the search, so EA tries to add 'AND t_object.Package_ID IN (...)' to the where clause but it doesn't work because you have aliased t_object. Try re-writing your query without the table aliases.
