Neoview Command Interface (NCI) Guide (R2.3)

Example
This command shows that the current schema of the session is PERSNL:
SQL>show schema
SCHEMA PERSNL
For more information, see “Setting and Showing the Current Schema” (page 65).
SHOW SCHEMAS Command
The SHOW SCHEMAS command displays all or a set of the schemas that exist in the default
catalog of the current NCI session.
Syntax
SHOW SCHEMAS [wild-card-pattern]
wild-card-pattern
is a character string used to search for and display schemas with names that match the
character string. wild-card-pattern matches an uppercase string unless you enclose it
within double quotes. To look for similar values, specify only part of the characters of
wild-card-pattern combined with these wild-card characters:
Use a percent sign (%) to indicate zero or more
characters of any type. For example, %art% matches
SMART, ARTIFICIAL, and PARTICULAR but not smart
or Hearts. "%art%" matches smart and Hearts but
not SMART, ARTIFICIAL, or PARTICULAR.
%
Use an asterisk (*) to indicate zero or more characters
of any type. For example, *art* matches SMART,
ARTIFICIAL, and PARTICULAR but not smart or
Hearts. "*art*" matches smart and Hearts but not
SMART, ARTIFICIAL, or PARTICULAR.
*
Use an underscore (_) to indicate any single character.
For example, boo_ matches BOOK and BOOT but not
BOO or BOOTS. "boo_" matches book and boot but
not boo or boots.
_
Use a question mark (?) to indicate any single character.
For example, boo? matches BOOK and BOOT but not
BOO or BOOTS. "boo?" matches book and boot but
not boo or boots.

Considerations
• You must enter the command on one line. The command does not require an SQL terminator.
• You can execute this command only in SQL mode.
• If you do not specify a wild-card pattern in a SHOW SCHEMAS command, NCI displays
all the schemas that exist in the default catalog.
• If you specify a wild-card pattern in a SHOW SCHEMAS command, NCI displays only the
schema names that match the wild-card pattern.
• If the SET TIMING command is set to ON, the elapsed time information is displayed.
Examples
• This command shows all the schemas that exist in the default catalog of the current session:
SQL>show schemas
