When migrating from Voyager to Alma you may want to identify and review those MFHDs that have an 866 subfield 8 encoded as "0" (zero). 

These two queries, which can be run using Voyager Prepackaged Access Reports, first create a table where there is an 866 subfield 8.  The second query then checks the table for those subfields which are encoded with "0".

NOTE that the first query is a BLOB query and can take a long time to run.

Run this query first to create your table:

SELECT MFHD_MASTER.MFHD_ID, MFHD_MASTER.RECORD_TYPE, getfieldall(getmfhdblob([mfhd_id]),'866','8') AS mfhd866subf8 INTO mfhds_866subf8_table
FROM MFHD_MASTER
WHERE (((MFHD_MASTER.RECORD_TYPE)='y'));

Then run this second query to check the results of the first for any row where subfield 8 is "0":

SELECT mfhds_866subf8_table.MFHD_ID, mfhds_866subf8_table.mfhd866subf8
FROM mfhds_866subf8_table
WHERE (((mfhds_866subf8_table.mfhd866subf8) Like "*0*"));
