How to get the actual result size of a SOQL

Question

I am using SOAP API to execute a SOQL. I need to get the size of my result

Does QueryResult.size() returns the actual size or the number of rows returned in the current execution

Consider I've a 45000 records and I want to get the count of the records. Executing a query will result in 500 records if I didn't modify the batch size.

So my question is, does QueryResult.size() will return me 45000 or 500? If it returns 500, is there any other way to get the count. I don't want to use select count() as the query is not constructed in my applicationm instead it is fed from some where.

Thanks in advance

According to the docs it's the number of records retrieved by the query, so I take that to mean 45,000 in your example:

Your client application can use this value to determine whether the query retrieved any rows (size > 0) or not (size = 0). Total number of rows retrieved in the query.

The QueryResult also includes a query locator which makes it easier to get the next group of records:

QueryLocator

In the QueryResult object returned by the query() call, queryLocator contains a value that you will use in the subsequent queryMore() call. Note the following guidelines:

• Use a given queryLocator value only once. When you pass it in a queryMore() call, the API returns a new queryLocator in the QueryResult .
• QueryLocator objects expire automatically after 15 minutes of inactivity.
