  4. Using PosgreSQL at TCU • Login in to Riogrande and psql sanchez% ssh riogrande.cs.tcu.edu sanchez@riogrande.cs.tcu.edu's password: ******** Last login: Mon Oct 10 19:54:57 2005 from tt3322.mat.tcu.edu [sanchez@riogrande ~]$ psql Welcome to psql 8.0.3, the PostgreSQL interactive terminal. • Use a template1 the first time [sanchez@riogrande ~]$ psql

  5. Using PosgreSQL at TCU • Help command in terminal psql • \h for SQL commands CREATE [ database | index | table | trigger | schema | rule ], COMMENT, COMMIT, ROLLBACK INSERT, SELECT, SELECT INTO FETCH • \? For system commands (i.e. Non SQL) \q quit psql \c[onnect] [DBNAME|- [USER]] connect to new database (currently "sanchez") • Create a database sanchez-# CREATE DATABASE • Fittings database • Employee database

  6. Using PosgreSQL • Insert data • 10 rows per table • Do some basic SQL • SELECT FROM

  7. Creating Tables • CREATE [ [ GLOBAL | LOCAL ] { TEMPORARY | TEMP } ] TABLE table_name ( { column_namedata_type [ DEFAULT default_expr ] [ column_constraint [ ... ] ] | table_constraint | LIKE parent_table [ { INCLUDING | EXCLUDING } DEFAULTS ] } [, ... ])[ INHERITS ( parent_table [, ... ] ) ][ WITH OIDS | WITHOUT OIDS ][ ON COMMIT { PRESERVE ROWS | DELETE ROWS | DROP } ] where column_constraintis: [ CONSTRAINT constraint_name ]{ NOT NULL | NULL | UNIQUE | PRIMARY KEY | CHECK (expression) | REFERENCES reftable [ ( refcolumn ) ] [ MATCH FULL | MATCH PARTIAL | MATCH SIMPLE ] [ ON DELETE action ] [ ON UPDATE action ] }[ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ] Sources: http://www.cs.nott.ac.uk/TSG/manuals/databases/postgres/tutorial/ http://www.postgresql.org/docs/7.4/interactive/sql-createtable.html http://archives.postgresql.org/pgsql-docs/2001-04/msg00069.php

  8. Using SELECT SELECT [ALL|DISTINCT] { * | expr_1 [AS c_alias_1] [, ... [, expr_k [AS c_alias_k]]]} FROM table_name_1 [t_alias_1] [, ... [, table_name_n [t_alias_n]]] [WHERE condition] [GROUP BY name_of_attr_i [,... [, name_of_attr_j]] [HAVING condition]] [{UNION [ALL] | INTERSECT | EXCEPT} SELECT ...] [ORDER BY name_of_attr_i [ASC|DESC] Sources: http://www.cs.nott.ac.uk/TSG/manuals/databases/postgres/tutorial/ http://www.postgresql.org/docs/7.4/interactive/sql-createtable.html http://archives.postgresql.org/pgsql-docs/2001-04/msg00069.php
