Question

Is there any equivalent to MySQL’s SHOW CREATE TABLE <tablename> in informix? I would like to run it in the SQL Manager on the Server Studio and would also like to obtain information about a tables columns and their types. Is this possible? I’ve found the systables, syscolumns and information schema, but wasn’t lucky with the results I got with the output of select * from... .

I don’t know such SQL command. From command line you can use dbschema utility:

C:\Informix>dbschema -t abc -d test
DBSCHEMA Schema Utility       INFORMIX-SQL Version 11.50.TC6DE

{ TABLE "informix".abc row size = 4 number of columns = 1 index size = 0 }
create table "informix".abc
  (
    xxx integer
  );

revoke all on "informix".abc from "public" as "informix";

If you want to read systables, then look at my script that dumps info about tables, columns, indexes etc: http://code.activestate.com/recipes/576621-dump-informix-schema-to-text/?in=user-186902 . In its source you will find systables queries you can use.
