You can use the CREATE TABLE statement to create relational-database tables or to create typed tables (object-relational tables). For information on how to create temporary tables, see CREATE Temporary TABLE .

The CREATE TABLE statement can include various clauses, some of which are identified in the following list. Clauses whose names are followed by "(IDS)" are not supported by Extended Parallel Server. Similarly, clauses whose names are followed by "(XPS)" are not supported by Dynamic Server.
Clause | Page | What the Clause Specifies |
---|---|---|
Logging Options | Logging Options | Logging characteristics of the new table |
Column Definition | Column Definition | Name and other attributes of an individual column |
DEFAULT | DEFAULT Clause | Default value for an individual column |
Single-Column Constraint | Single-Column Constraint Format | Data-integrity constraints on an individual column |
REFERENCES | REFERENCES Clause | Referential-integrity constraints with other columns |
CHECK | CHECK Clause | Check constraints with other columns |
Constraint Definition (IDS) | Constraint Definition | Name and other attributes of a constraint |
Multiple-Column Constraint | Multiple-Column Constraint Format | Data-integrity constraints on a set of columns |
WITH CRDCOLS (IDS) | Using the WITH CRCOLS Option (IDS) | Two shadow columns for Enterprise Replication |
Storage Options | Storage Options | Attributes of where the table is physically stored |
IN | Using the IN Clause | Storage object to hold the new table (or part of it) |
FRAGMENT BY or PARTITION BY | FRAGMENT BY Clause | Distribution scheme of a fragmented table |
WITH ROWIDS (IDS) | Using the WITH ROWIDS Option (IDS) | Hidden column in a fragmented table |
RANGE METHOD (XPS) | RANGE Method Clause (XPS) | Fragmentation strategy based on column values |
PUT (IDS) | PUT Clause (IDS) | Storage location for BLOB or CLOB column values |
EXTENT SIZE | EXTENT SIZE Options | Size of the first and subsequent extents |
USING ACCESS METHOD (IDS) | USING Access-Method Clause (IDS) | How to access the new table |
LOCK MODE | LOCK MODE Options | Locking granularity of the new table |
OF TYPE (IDS) | OF TYPE Clause (IDS) | Named ROW type of a new typed table |
UNDER (IDS) | Using the UNDER Clause | Supertable of a new subtable in a table hierarchy |
When you create a new table, every column must have a data type associated with it. The table name must be unique among all the names of tables, views, sequences, and synonyms within the same database, but the names of columns need only be unique among the column names of the same table.
In an ANSI-compliant database, the combination owner.table must be unique among tables, synonyms, views, and sequence objects within the database.
In DB–Access, using CREATE TABLE outside the CREATE SCHEMA statement generates warnings if you use the -ansi flag or if you set DBANSIWARN.
In ESQL/C, using CREATE TABLE generates warnings if you compile with the -ansi flag or set DBANSIWARN. For information about the DBANSIWARN environment variable, see the IBM Informix Guide to SQL: Reference.
