sqliteHow do I use a SQLite join to combine two tables?
A SQLite join is used to combine two tables by combining their columns. The syntax for a join is as follows:
SELECT <columns_to_select>
FROM <table1>
JOIN <table2>
ON <table1>.<column> = <table2>.<column>;
The SELECT
clause is used to specify which columns you want to view from the two tables. The FROM
clause is used to specify which tables you want to join. The JOIN
clause is used to specify how the two tables are to be joined. The ON
clause is used to specify which columns are used to match up the two tables. For example, if you have two tables named customers
and orders
, you could join them together like this:
SELECT customers.name, orders.order_date
FROM customers
JOIN orders
ON customers.customer_id = orders.customer_id;
This would return the names of customers and the dates of their orders.
