Data loader behaviour when a record fails to upsert
I upserted 150 records wiith salesforce data loader. The batch size was set as 200.A single record in that 150 records failed to upload but the error was shown for all the 150 and none of the record was upserted,but in a seperate incident the data loader upserted 149 records and showed error for only that one record. What is this behaviour of data loader and how can it be changed ?
In APEX terms there are 2 options one is Insert and othetr one is Database.Insert
In INsert - the system will either upload all the records or reject all the records.
In Database.Insert the system will upload all those which pass the validations and only ones with errors will not be loaded.
By Default Dataloader loads in Database.Insert type of uploads.
Looks like it is a one off issue due to some internal server issues, Try again and it should load the ones without errors.

What is the difference between database.insert and insert ?
Ans:
insert is the DML statement which is same as databse.insert. However, database.insert gives more flexibility like rollback, default assignment rules etc. we can achieve the database.insert behavior in insert by using the method setOptions(Database.DMLOptions)
Important Difference:
If we use the DML statement (insert), then in bulk operation if error occurs, the execution will stop and Apex code throws an error which can be handled in try catch block.
If DML database methods (Database.insert) used, then if error occurs the remaining records will be inserted / updated means partial DML operation will be done.
