MarkLogic Server 11.0 Product Documentationop:join-doc-cols
op:join-doc-cols( $cols as map:map, $sourceCol as item() ) as map:map
Summary
This function populates the view with the uri, doc, collections, metadata, permissions, and / or quality document descriptor columns for database document values.
| Parameters | |
|---|---|
| $cols | Supplies a document column identifier map to specify which document columns to join and their names. The names cannot conflict with existing column names. To use the default column names, use op:doc-cols or an empty sequence. |
| $sourceCol | The source column to join. This is either an op:fragment-id-col specifying a fragment id column or a op:col, op:view-col or op:schema-col that contains document uris. Joining on a fragment id is more efficient than joining on an uri column. |
