I have the following query (119 lines long) which runs fine in Oracle SQL Developer and give me exactly what I need.

When I then try to use is in Microsoft PBI I get the following error "ORA-01843: not a valid month" The stage thing is there is month in the query.

Any ideas?

Thanks in advance.

    Hi, @User_3KSKY

    Whenever you have a question, please post CREATE TABLE and INSERT statements for a little sample data, so the people who want to help you can re-create the problem and test their ideas. Also post the exact results you want from that data, and explain why you want those results from that data. Always post your complete Oracle version (e.g.

    Simplify the problem. Eliminate all tables and columns that have nothing to do with the issue.

    Never write, let alone post, unformatted code.

    Hi, @User_3KSKY

    "ORA-01843: not a valid month" is caused by a bad DATE or TIMESTAMP conversion, including implicit conversions (where you use some other data type where a DATE or TIMESTAMP is required). Check all the places where you are using DATEs or TIMESTAMPs. For example:

    dstamp >= to_timestamp(trunc(SYSDATE-(1/24)))

    is a mistake. The first argument to TO_TIMESTAMP is supposed to be a string, but you're passing a DATE instead. (The value returned by TRUNC is a DATE.) Also, don't call TO_TIMESTAMP with only one argument; explicitly give a second argument, because the default may not be what you want or expect.
