Which SQL query retrieves all rows where the 'name' column does not start with the letter 'A'?

To retrieve all rows where the 'name' column does not start with the letter 'A', you can use the SQL query with the NOT LIKE operator. Here is the step by step process:

1. Start with the SELECT statement. This is used to select data from a database. The data returned is stored in a result table, called the result-set.

2. Specify the column(s) you want to select. In this case, we want to select all columns, so we use *.

3. Use the FROM keyword, which is used to specify the table from which to retrieve the data.

4. Specify the table name.

5. Use the WHERE clause to filter records. This is where we specify that the 'name' column should not start with 'A'.

6. Use the NOT LIKE operator to search for a specified pattern in a column.

7. The pattern we're looking for is any name that does not start with 'A'. In SQL, we can use the % wildcard to represent zero, one or multiple characters. So, we specify 'A%' to represent any string that starts with 'A'.

Here is the complete SQL query:

SELECT * FROM table_name
WHERE name NOT LIKE 'A%';

Replace table_name with the name of your table. This query will return all rows from the table where the 'name' column does not start with the letter 'A'.
