When using IBM DB2, there may come a time where you wish to view the structure of your database or even of specific tables. In this brief tutorial, we’ll explore two different methods of examining your database tables in more detail to see just what the
schema
really looks like.Using SYSIBM Catalogs
The first method for examining your database table structure makes use of the handy
SYSIBM
catalogs provided by DB2, which contain a wide array of meta information about the database and the tables therein.Specifically, we can utilize either
SYSIBM.SYSTABLES
or SYSIBM.SYSCOLUMNS
. For generic meta data about the table itself, you’ll likely wish to query SYSIBM.SYSTABLES
, but if you’re specifically looking for the schema
(column names, data types, etc), you’ll instead need to use SYSIBM.SYSCOLUMNS
.Contains information about all columns in all tables and views. This table resides in the DSNDB06 database in each location. Don't select generated columns in target table ( table1) insert into table1 select col2,col3,col4 from table2. Assume col1 in table is generated column. 60 rows The SYSIBM.SYSTABLES table contains one row for each table, view, or alias. How to get the last generated value of an identity column. How to get the last generated value of an identity column for a given table? DB2 Database Forums on Bytes.
A basic query using
.SYSCOLUMNS
would look something like this:The column names we’re selecting are fairly self-explanatory, with perhaps the exception of
SCALE
which defines the number of fractional digits for DECIMAL
column types.For example, if we wanted to return a query of column information about our
books
table, we’d just replace MyTableName
with books
:Using the DESCRIBE Command

For a simpler query that forgoes control over the data returned in the result set, you may also use the
DESCRIBE
command.DESCRIBE
essentially displays the meta data contained within the assorted SYSIBM
catalogs mentioned above, but only does so based on the type of DESCRIBE
query you execute. You can ask DB2 to DESCRIBE
information about tables
, indexes
, columns
, and even specific SELECT
statement queries, if so desired.Sysibm Table For Auto Generated Key 2016
For our purposes, we’ll use
DESCRIBE
to once again retrieve the details of a specific table
, which is performed with this simple query:Thus, if we want to retrieve information about our
books
table that is part of our bookstore
schema, we’d simply execute the following query:Battlefield 4 Premium gets you all the best weapons, camos, vehicles and more in one simple package.Experience all the action of the with, a new installment that will make you live Second World War like never before, with great customization options and remarkable improvements regarding team mechanics among other novelties.Compare game prices.

In addition to the basic column information above, you may also wish to view the indices that are part of your table. Thankfully, there is a simple option with the
DESCRIBE
keyword to query this data quite easily:Sysibm Table For Auto Generated Key Fob

The result set is a detailed list of all indices connected to that table, like so:
