In the example below, I add to my insert clause the "returning" along with the primary key of my table, then after the execute, I do a fetch getting an array with the value of the last inserted id. Sometimes it is useful to obtain data from modified rows while they are being manipulated. Responses .

This function used to be called pg_getlastoid(). Otherwise oid is zero.. PostgreSQL 8.0 function is necessary. PL/pgSQL variables will be substituted into the rest of the query, and the plan is cached, just as described above for commands that do not return rows. // Yup, your eyes are ok, NOT exec but query!!!

It should be noted that, at least for MySQL using InnoDB tables, with transactions PDO will report the last insert id as 0 after the commit, the real ids are only reported before committing. This is not so useful in trivial inserts, since it would just repeat the data provided by the client. into the newindex variable for further actions. It should be mentioned that this function DOES NOT retrieve the ID (Primary key) of the row but it's OID instead. Currently I'm doing it with two queries: About the connections created through classes, Easiest solution I've found for MSSQL to obtain the last inserted ID is, "SELECT CAST(COALESCE(SCOPE_IDENTITY(), @@IDENTITY) AS int)". no available OID. function, naming the sequence whose last value is required.

This function is not available for MSSQL either. For PostgreSQL you can still use the old solution to return the last Id of an INSERT, selecting the currval of a table's id_sequence. a sequence object for the name parameter. To combat this put it into a transaction and dont commit till you have done all the work. If you need to insert a varying value into such a command, do so as part of constructing the string value, or use USING, as illustrated in Section 40.5.4. I think I get a nice solution in Postgres to get the ID using the RETURNING that comes with Postgress since version 8.2. A string containing the OID assigned to the most recently inserted in this video we Create postgresql database and connect iti using php codes RETURNING id; By using the RETURNING keyword on the end of my insert query, I can have PostgreSQL return those new values to me as part of the same operation.
