DB2 view all tables and their information

Question

Is there a statement that will let me view all the tables on a database, their respective column names, and any other pertinent data?

I imagine I have to query the system catalogs? I am new to DB2 and unsure of how to proceed.

Answer 1

Connect to the database:

db2 connect to <database-name>

List all tables:

db2 list tables for all

To list all tables in selected schema, use:

db2 list tables for schema <schema-name>

To describe a table, type:

db2 describe table <table-schema.table-name>

Answer 2

Yes there is, the COLUMNS view

DB2 for i select * from sysibm.columns http://pic.dhe.ibm.com/infocenter/iseries/v7r1m0/topic/db2/rbafzcatalog.htm

DB2 for LUW select * from syscat.columns http://pic.dhe.ibm.com/infocenter/db2luw/v10r5/topic/com.ibm.db2.luw.sql.ref.doc/doc/r0008443.html
