Batch Apex : Can we pass record number to scope object?

Hi,

 

When we call Batch apex using Query in developer console, Can we specify number of record which we need to process at a time after the query?

 

For eg:

 

Id batchInstant = executeBatch(new BatchClass(Select id, Name from Account), 200);

 

In above syntax, 200 represents batch size of 200 So SF will chuncks number of records in 200 records batch.

My question is, if there are 5000 records can we pass directly at 200 place in the above query?

 

Thanks.

It will take 2000 not 200.

Yes. But the maximum value is 2000 only.

 

Each execution of a batch Apex job is considered a discrete transaction. For example, a batch Apex job that contains 1,000 records and is executed without the optional scopeparameter fromDatabase.executeBatchis considered five transactions of 200 records each. The Apex governor limits are reset for each transaction. If the first transaction succeeds but the second fails, the database updates made in the first transaction are not rolled back.
