3.7.22TABLE

Syntax

T[ABLE] [ tablename ] ;

Description

The TABLE statement with no argument displays a list of all the user tables in the database that are owned by the current user.

With the tablename argument, the TABLE statement displays a brief description of the col- umns in the specified table.

Examples

You can use the TABLE statement to see the structure of system tables. Unless you are logged in as the c-treeSQL database administrator (the user ADMIN, by default), you need to qualify the system table name with the administrator user name, as in the following example:

ISQL> table ADMIN.systables	NULL ?	TYPE	LENGTH
COLNAME	NULL ?	TYPE	LENGTH
-------	------	----	------
id	NOT NULL	INT	4
tbl	NOT NULL	VARCHAR	32
creator	NOT NULL	VARCHAR	32
owner	NOT NULL	VARCHAR	32
tbltype	NOT NULL	VARCHAR	1
tblpctfree	NOT NULL	INT	4
segid	NOT NULL	INT	4
has_pcnstrs	NOT NULL	VARCHAR	1
has_fcnstrs	NOT NULL	VARCHAR	1
