Given a database name and other qualifying information, this command
will query the system catalogs for information and format the results.
It must be issued on the server.

Command parameters
- -d dbname
- dbname is the name of the database for which
the command will query the system catalogs.
- -h
- Displays usage information.
- -l
- Turns on case sensitivity for the object name.
- -n name
- Specifies the name of the object.
- -o outfile
- Specifies the name of the output file.
- -p descriptor
- Specifies the name of the packed descriptor (pd) to display where descriptor is
one of the following values:
- check
- Display table check constraints packed descriptor.
- controls
- Displays packed descriptors for all enabled permissions and masks
for a given table.
- rel
- Display referential integrity constraint packed descriptor.
- table
- Display table packed descriptor. This includes the inline length
if at least one exists for the table.
- summary
- Display summary table packed descriptor.
- syscontrols
- Displays the packed descriptor for a given mask or permission.
- trig
- Display table trigger packed descriptor.
- view
- Display view packed descriptor.
- variable
- Display global variable packed descriptor.
- remote
- Display remote non-relational data sources packed descriptor.
- ast
- Display materialized query table packed descriptor.
- routine
- Display routine packed descriptor.
- sysplan
- Display package packed descriptor.
- datatype
- Display structured type packed descriptor.
- sequence
- Display sequence packed descriptor.
- esri
- Display key transformation thread and index extension packed descriptor.
- event
- Display event monitor packed descriptor.
- server
- Display server packed descriptor.
- auth
- Display privileges held by this grantee on this object.
- -vi versionID
- Specifies the version ID of the package packed descriptor. -vi is
only valid when -p sysplan is specified. If versionID is
omitted, the default is the empty string.
- -s schema
- Specifies the name of the object schema.
- -t
- Displays terminal output.
- -v
- Validates packed descriptor. This parameter is only valid for
table packed descriptors.
- -x
- Validates table space extent size in catalogs (does not require
a table name).
- -cb
- Cleans orphan rows from SYSCAT.BUFFERPOOLDBPARTITIONS (does
not require a table name).
Examples
- Example 1
The following command prints the packed descriptor information
for the table splt_tb1 with schema raguk from database testdb to terminal:
db2cat -d testdb -s raguk -t -n splt_tb1
Usage notes
- The options -d, -s and -n are
mandatory when executing the db2cat command.
- Table name and table schema may be supplied in LIKE predicate
form, which allows percent sign (%) and underscore (_) to be used
as pattern matching characters to select multiple sources with one
invocation.
- Prompting will occur for all fields that are not supplied or are
incompletely specified (except for the -h and -l options).
- If -o is specified without a file name, and -t is
not specified, you will be prompted for a file name (the default name
is db2cat.out).
- If neither -o nor -t is
specified, you will be prompted for a file name (the default is terminal
output).
- If -o and -t are both
specified, the output will be directed to the terminal.
