Methods

getAccountRecordsInState(String state) → List<Account>

Demonstrates how to use a bound variable in a WHERE clause

Type

getChunksOfLargeNumbersOfRecords() → Integer[]

One of the little known features of SOQL for loops is that you can iterate not only over each record returned by the query, but also over each chunk of records. As the code below demonstrates, specifying the iteration variable as a list/array will return 200 record chunks from the query, rather than individual records. Note: Normally, if you're only dealing with counts of records, you'd utilize the Count() soql method, but in this case we're demonstrating that this form of a soql for loop gives you access both to a list of records, and to the records themselves.
