Update the current query band name:value pairs as follows.
- If the query band name matches a name in the current query band, then the system replaces the value.
- If the query band name does not match a name in the current query band, then the system adds the name:value pair.
The only way to remove a name:value pair from a query band is to replace the entire query band.
If an update causes the new query band to exceed the maximum allowable length, the system returns an error to the requestor.
Note that a name can be set to a zero-length string by specifying ‘ pair_name =;’.
If you do not specify UPDATE, then the entire current query band is replaced by the new query band.
You cannot specify both the NONE option and the UPDATE option within the same request.
