Shredding the Lock Plan Information | Teradata Vantage - Shredding the Lock Plan Information in the XML Lock Log Table, DBQLXMLLockTbl - Advanced SQL Engine - Teradata Database

You can shred (format as a table) the lock plan information in the XMLTextInfo column of DBQLXMLLockTbl to be able to query it and read it. Without shredding, output from that column typically looks like this:

sel xmltextinfo from dbc.dbqlxmllocktbl;
 *** Query completed. 7 rows found. One column returned.
 *** Total elapsed time was 1 second.
