op:write( [$docDescCols as map:map?] ) as map:map
Summary
Inserts or overwrites the documents identified by the uri column with the data supplied by the other document descriptor columns.
| Parameters | |
|---|---|
| $docDescCols | A map to specify which document columns to use when writing. If this parameter is not passed in op:doc-cols() is used as default. |
Usage Notes
op:write() needs to be run as an update transaction. Use 'declare option xdmp:update "true";' in the prolog, or use xdmp:invoke/xdmp:invoke-function with update="true".See Also
