With SQL, how do you select all the records from a table named "Persons" where the value of the column "FirstName" starts with an "a"?

To select all the records from a table named "Persons" where the value of the column "FirstName" starts with an "a", you can use the following SQL query:

SELECT * FROM Persons WHERE FirstName LIKE 'a%';

Here's a breakdown of the query:

1. The SELECT statement is used to retrieve data from the table.
2. The * symbol is a wildcard that represents all columns in the table.
3. The FROM keyword specifies the table name "Persons" from which the data will be retrieved.
4. The WHERE clause is used to filter the records based on a condition.
5. The FirstName column is specified after the WHERE keyword.
6. The LIKE operator is used to match patterns in the column values.
7. 'a%' is the pattern used to match values that start with the letter "a".
8. The semicolon (;) is used to end the SQL statement.

Executing this query will return all the records from the "Persons" table where the value of the "FirstName" column starts with an "a".
