DataSource.Error: Oracle: ORA-01795: maximum number of expressions in a list is 1000

Hello everyone,

 

Using the example from this page:  https://radacad.com/dynamic-sql-using-power-query#comments

I have a table call private_charges_facts where a column respondent_seq (unique identifier) which I turned into a list called Respondent_list (no duplicates).  I want to create a new query called respondent_DIM that will pass respondent_list into my new query to get only the records that I need from private_charges_facts.  All syntax went well until I refresh and hit the oracle limit (see below).  It's fine if my respondent_list is below 1000 records.  Any other way to approach this?

You could try to split the list into several smaller lists that has fewer than 1000 members, then use OR conditions in your WHERE statements for each list.
