SQL CREATE TABLE Syntaxis - weergegeven door DBMS

Dit artikel bevat de SQL CREATE TABLE syntaxis, zoals geïmplementeerd door verschillende databasebeheersystemen (DBMS'en). De syntaxis wordt precies weergegeven zoals elke leverancier deze op hun website heeft vermeld. Klik op de toepasselijke link om meer details over de syntaxis voor een bepaalde leverancier te bekijken.

De gedekte DBMS'en zijn MySQL, SQL Server, PostgreSQL en Oracle Database.

PostgreSQL

Uit de PostgreSQL 9.5-handleiding:

) ]

[ ON COMMIT { PRESERVE ROWS | DELETE ROWS | DROP } ]
[ TABLESPACE tablespace_name ]

where column_constraint is:

[ CONSTRAINT constraint_name ]
{ NOT NULL |

  CHECK ( expression ) [ NO INHERIT ] |
  DEFAULT default_expr |
  UNIQUE index_parameters |
  PRIMARY KEY index_parameters |
  REFERENCES reftable [ ( refcolumn ) ] [ MATCH FULL | MATCH PARTIAL | MATCH SIMPLE ]
    [ ON DELETE action ] [ ON UPDATE action ] }
[ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]

and table_constraint is:

[ CONSTRAINT constraint_name ]
{ CHECK ( expression ) [ NO INHERIT ] |
  UNIQUE ( column_name [, ... ] ) index_parameters |
  PRIMARY KEY ( column_name [, ... ] ) index_parameters |
  EXCLUDE [ USING index_method ] ( exclude_element WITH operator [, ... ] ) index_parameters [ WHERE ( predicate ) ] |

[ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]

and like_option is:

{ INCLUDING | EXCLUDING } { DEFAULTS | CONSTRAINTS | INDEXES | STORAGE | COMMENTS | ALL }

index_parameters in UNIQUE, PRIMARY KEY, and EXCLUDE constraints are:

[ WITH ( storage_parameter [= value] [, ... ] ) ]
[ USING INDEX TABLESPACE tablespace_name ]

exclude_element in an EXCLUDE constraint is:

Oracle-database

Uit de Oracle Database Online Documentation 12c Release 1 (12.1):

CREATE [ GLOBAL TEMPORARY ] TABLE [ schema. ] table
  { relational_table | object_table | XMLType_table } ;

Het volgende geeft details over elk van de drie opties.

relational_table

[ (relational_properties) ]
[ ON COMMIT { DELETE | PRESERVE } ROWS ]
[ physical_properties ]
[ table_properties ]

object_table

OF
   [ schema. ] object_type
   [ object_table_substitution ]
   [ (object_properties) ]
   [ ON COMMIT { DELETE | PRESERVE } ROWS ]
   [ OID_clause ]
   [ OID_index_clause ]
   [ physical_properties ]
   [ table_properties ]

XMLType_table

OF XMLTYPE
  [ (oject_properties) ]
  [ XMLTYPE XMLType_storage ]
  [ XMLSchema_spec ]
  [ XMLType_virtual_columns ]
  [ ON COMMIT { DELETE | PRESERVE } ROWS ]
  [ OID_clause ]
  [ OID_index_clause ]
  [ physical_properties ]
  [ table_properties ]

Raadpleeg de officiële documentatie van Oracle voor meer informatie over de verdere beschikbare opties voor elk van deze.

De GUI gebruiken

Het maken van tabellen kan ook worden gedaan via de GUI in elk van de databasebeheersystemen, of door een van de GUI-tools te gebruiken die beschikbaar zijn voor gebruik met dat product.

U kunt bijvoorbeeld een tabel maken via de GUI wanneer u met MySQL Workbench werkt.
