How to get DB2 Table details using C#

Question

How I can connect and use DB2 in the C# application? How I can get the table names of a DB2 database? How I can see the each column name, its datatype, size, etc of a table using C#?

Answer 1

This assumes you're using DB2 for Linux/Unix/Windows. If you're using another platform, it will likely have a different catalog table.

Once you have connected to the database, you can query the information from the system catalog, specifically SYSCAT.COLUMNS .

For example, if you have a table called SCHEMA.TABLE , you could get the list of all the columns using a query like this:

SELECT *
FROM SYSCAT.COLUMNS
WHERE TABSCHEMA='SCHEMA'
  AND TABNAME  ='TABLE'
