Question

I’ve almost got the query below working, however the two fields qcare_end and warranty_end both generate an invalid identifier error when executing the script
Also – i’m hoping to use this script (and a couple like it) to generate a series of operations that will take a subset of data from our oracle contract and part management database and squirt it into a mysql database which we use in support when logging incidents

    Select
    'Insert Into mysqldbtable (system_id, customer_code,, serial_no, system_type, description, qcare_end, warranty_end) Values (''' 
    || system_id || ''',''' || customer_code || ''',''' || serial_no || ''',''' || system_type || ''',''' || description ||  ''')'
  FROM (SELECT SYSTEMS.SYSTEM_ID
               --            ,SYSTEMS.SITE_NAME
              , CUSTOMER_ADDRESSES.CUSTOMER_CODE

where ROWNUM <= 10 ORDER BY SERIAL_NO;

This just returns 10 results, and it seems pretty sane – but if I re-add the qcare and warranty end dates, it fails with the following error:

65 where ROWNUM <= 10 ORDER BY SERIAL_NO;
|| system_id || ”’,”’ || customer_code || ”’,”’ || serial_no || ”’,”’ || system_type || ”’,”’ || description || ”’,”’
||qcare_end|| ”’,”’ ||warranty_end|| ”’)’
* ERROR at line 3: ORA-00904: “WARRANTY_END”: invalid identifier

I’m not sure why table aliases wouldn’t work – it seems to be fine in regular queries, but not when I’m trying to generate the import statements that I can then pipe into mysql periodically.

Any thoughts on what I’m missing?

Answer 1

Scott,

The aliases don’t work because you’ve put them in double quotes and in mixed case (hint: don’t do that). That means you have to reference them that way:

SELECT "qcare" FROM (your_query)

You probably want this instead, which makes your aliases all upper case:

, TO_DATE(NULL) AS qcare_end
, MAX(systems.warranty_end) AS warranty_end

And

, MAX(EI.END_DATE) AS QCare_End
, TO_DATE(NULL) Warranty_End

Technically, you don’t need the aliases in the second half of the union anyway, it’s the first half of the union that drives the column names for the in-line view.
