OrientDB批量更新后如何返回指定属性而非RecordLink？

The issue with your current batch command is that you're returning an array of full records (represented as OrientDBRecordLink objects), which don't directly give you the key-value format you want. Instead, you need to build a map incrementally in your batch script that maps each updated name to its RID.

Here's the corrected batch command that will return the exact format you're looking for:

begin;
-- Initialize an empty map to store our name-RID pairs
let result = {};

-- First update: modify the record and capture the updated version
let a0 = update #44:845 merge {"name": "B4"} return after;
-- Add the name and RID to our result map (convert RID to string for the desired format)
let result = result.put($a0.name, $a0.@rid.toString());

-- Second update
let a1 = update #44:849 merge {"name": "Name4"} return after;
let result = result.put($a1.name, $a1.@rid.toString());

-- Repeat the above two lines for all your updates...

-- Commit the transaction with retry logic
commit retry 100;

-- Return the final map
return result;

Key Details: #

1. Initializing the Map: We start with let result = {} to create an empty dictionary that will hold our key-value pairs.
2. Capturing Updated Records: Each update ... return after statement stores the fully updated record in a variable (like $a0). This gives us access to both the new name property and the record's @rid.
3. Building the Map: Using result.put(key, value), we add each entry to the map. We call toString() on @rid because it's an ORecordId object by default—converting it to a string gives you the familiar #44:845 format.
4. Commit and Return: After all updates are processed, we commit the transaction and return the completed map.

Important Notes: #

• If multiple updates set the same name value, the last one will overwrite the previous entry in the map (since map keys must be unique).
• The merge operation ensures the name property is set (even if it didn't exist before), so you don't have to worry about missing values in the result.
