postgres select from insert returning

But how do I catch the value into the variable? * PostgreSQL Stored Procedures and Functions - Getting Started To return one or more result sets (cursors in terms of PostgreSQL), you have to use refcursor return type. The RETURNING syntax is more convenient if you need to use the returned IDs or values … Both stored procedures and user-defined functions are created with CREATE FUNCTION statement in PostgreSQL. I want to build a function which will insert an email if the email value doesn't exist in the table and return the email_id of the row. Also how can I return the id if the email was not inserted and it already exist in the DB? INSERT INTO upsert_table VALUES (2, 6, 'upserted') ON CONFLICT DO NOTHING RETURNING *; id | sub_id | status ----+-----+----- (0 rows) Note as well that RETURNING returns nothing, because no tuples have been inserted. On successful completion, an INSERT command returns a command tag of the form. RETURNING * -- DB2 SELECT * FROM FINAL TABLE (INSERT INTO ..) Oracle also knows of a similar clause. INSERT conforms to the SQL standard, except that the RETURNING clause is a PostgreSQL extension, as is the ability to use WITH with INSERT. Furthermore, note that this option requires writing two separate queries, whereas PostgreSQL’s RETURNING clause allows you to return data after an insert with just one query. Do I need to perform another SELECT? You can get confusing results that way. INSERT oid count. On Postgres and DB2, you can also execute this for INSERT statements: ResultSet rs = statement.executeQuery(); The SQL syntax to fetch a java.sql.ResultSet from an INSERT statement works like this:-- Postgres INSERT INTO .. The RETURNING keyword in PostgreSQL gives an opportunity to return from the insert or update statement the values of any columns after the insert or update was run. Now with DO UPDATE, it is possible to perform operations on the tuple there is a conflict with. The newest releases of PostgreSQL are … return newindex; end; Well, the problem is that I want the id of the new post to be saved into the newindex variable for further actions. Outputs. The RETURNING keyword in PostgreSQL gives you an opportunity to return, from the insert or update statement, the values of any columns after the insert or update was run. For PostgreSQL 10, I have worked on a feature called “identity columns”. The count is the number of rows inserted or updated.oid is always 0 (it used to be the OID assigned to the inserted row if count was exactly one and the target table was declared WITH OIDS and 0 otherwise, but creating a table WITH OIDS is not supported anymore). How can I do this? INSERT INTO .. Depesz already wrote a blog post about it and showed that it works pretty much like serial columns: CREATE TABLE test_old ( id serial PRIMARY KEY, payload text ); INSERT INTO test_old (payload) VALUES ('a'), ('b'), ('c') RETURNING *; and CREATE TABLE […] Becuse the queries are executed in the same snapshot, the SELECT will not see the effects of the UPDATE statement. WITH updated AS (UPDATE test SET description = 'test' RETURNING id) SELECT * FROM test WHERE id IN (SELECT id FROM updated); Be careful with selecting from the just modified table. Again, this only works if your IDs form a discrete sequence, which is the case with the SERIAL auto-incrementing integer type. Should I do: select id from insert into foo (a,b) values (default,bvalue) returning id;? I mentioned this in passing in a few of my talks that touch on PostgreSQL recently, and it often gets twitter comment so here's a quick example of the RETURNING keyword in PostgreSQL. Also, the case in which a column name list is omitted, but not all the columns are filled from the VALUES clause or query , is disallowed by the standard.
