How To Populate Serial Key Field Postgres Insert Statement
- PostgreSQL Tutorial
A query (SELECT statement) that supplies the rows to be inserted. Refer to the SELECT statement for a description of the syntax. An expression to be computed and returned by the INSERT command after each row is inserted. The corresponding column will be filled with its default value. A query (SELECT statement) that supplies the rows to be inserted. Refer to the SELECT statement for a description of the syntax. An expression to be computed and returned by the INSERT command after each row is inserted. I am using a function call to insert the data, and while the create statement works, I am doing something wrong during the execution of it (so either a) I didn't write the statement properly or b) I didn't pass data in properly). CREATE TABLE main_data( id SERIAL PRIMARY KEY, field_1 TEXT, some_time DATE ); CREATE TABLE locale_data( locale. In PostgreSQL, you can also insert a record into a table using the DEFAULT VALUES syntax. For example: INSERT INTO contacts (contact_id, last_name, first_name, country) DEFAULT VALUES; This PostgreSQL INSERT statement would result in one record being inserted into the contacts table. Using the Serial Data Type. By far the simplest and most common technique for adding a primary key in Postgres is by using the SERIAL or BIGSERIAL data types when CREATING a new table. If the column is indeed defined as serial (there is no 'auto increment' in Postgres) then you should let Postgres do it's job and never mention it during insers: insert into context (some_column, some_other_column) values (42, 'foobar'); will make sure the default value for the context_id column is applied. Alternatively you could use.

Most efficient way to add a serial column to a huge table. Ask Question 9. The new bigserial column is missing in the SELECT of the INSERT and will be filled with its default value automatically. PostgreSQL replace primary key and converting non-serial to serial type.

PostgreSQL has the data types smallserial, serial and bigserial; these are not true types, but merely a notational convenience for creating unique identifier columns. These are similar to AUTO_INCREMENT property supported by some other databases.

The type name serial creates an integer columns. The type name bigserial creates a bigint column. bigserial should be used if you anticipate the use of more than 231 identifiers over the lifetime of the table. The type name smallserial creates a smallint column.
