To retrieve all parent records along with their linked child records in a chained sequence, one can use the SQL JOIN clause to join the parent and child tables and retrieve the data. The JOIN clause connects two or more tables together based on a related column between them.
Here is an example SQL query to retrieve all parent records and their linked child records:
SELECT *
FROM parent_table
JOIN child_table ON parent_table.parent_id = child_table.parent_id
ORDER BY parent_table.parent_id
This query will retrieve all parent records along with their linked child records in a chained sequence based on the parentid column. The JOIN clause connects the parenttable and childtable based on the parentid column and retrieves all columns from both tables. The ORDER BY clause orders the results by the parent_id column.
Note: The specific syntax may vary depending on the database management system being used.
