Hi All,
is it possible to update a single attributes of a Dynamodb Item with out overriding the existing details of other attributes ??
Example :
attributes in a dynamo item -> Employee_Id(partition key), Employee_Department(sort key), Employee_Address, Employee_experience
and want to update only employee_experience with only providing Employee_Department (sort key) in query
Currently I am using the following query to update the Employee_experience however Employedd_address is getting overriden to empty after executing this query
Query ::
QueryEnhancedRequest.builder()
.queryConditional(QueryConditional.keyEqualTo(Key.builder().partitionValue(Employee_Department).build()))
.exclusiveStartKey(startKey)
.scanIndexForward(false)
.build();
Please kindly let me know if you need any further details

Hi @Leeroy Hannigan, Thanks for the suggestion I changed the logic to update a item in dynamoDB which helped me to solve the problem Initially I used : employeeTable.updateItem(Employeeitem) Note : *EmployeeItem = the modelled item to be inserted into or updated in the database table.
Updated logic: I updated the logic to use updateItem(UpdateItemEnhancedRequest<T> request) with UpdateQuery
UpdateItemEnhancedRequest<Employee> request = UpdateItemEnhancedRequest .builder(Employee.class) .item(employee) .ignoreNulls(true) -> this actually helped me avoid overriding the existing data with null values in update query .build();
Thanks for you help and pointing to me correct documentation
