Question

I have executed the following create statement using SQLWorkbench at my target postgresql database:

  CREATE TABLE Config (    
  id serial  PRIMARY KEY,       
  pub_ip_range_low  varchar(100),       
  pub_ip_range_high varchar(100)            
  );

Right after table creation I request the table content by typing ‘select * from config;’ and see that table could be retrieved. Nevertheless, my java program that uses JDBC type 4 driver cannot access the table when I issue the same select statement in it. An exception is thrown when the program tries to access it which says says "Undefined relation" for the config table.

My questions are:

1. Why sqlworkbench where I had previously run the create statement recognizes the table while my java program cannot find it?
2. Where does the postgressql DBMS puts the tables I created? I don’t see them neither in public nor in information schema.

NOTE:
I checked target postgres database and cannot see the table Config anywhere although SQL workbench can query it. Then I opened another SQL workbench instance and noticed that the table cannot be queried (i.e. not found). So, my conclusion is that PostgreSQL puts the table I created in the first running SQLBench instance into some location that is bound to that session. Another SQL Workbench instance or my java program is not bound to session, so cannot query the previously created table config.

Answer 1

Maybe the create failed on the extra trailing comma?

 CREATE TABLE config (
  id serial  PRIMARY KEY,       
  pub_ip_range_low  varchar(100),       
  pub_ip_range_high varchar(100)   -- >> ,           
  );
