how to obtain data from hp vertica tables and from vertica projections?
I've connected to hp vertica database 7.1.2 and I want to obtain test data of tables created previously in my hp vertica database
I've installed vsql client and I've connected correctly to hp vertica database with vsql client.
Now I want to obtain data from vertica tables and from vertica projections.
I've executed some SELECT commands and these have fail.
vsql> \ select * from <table_name>
How could I obtain data from hp vertica projections and from vertica tables?
Which commands have I use to obtain data from vertica projections?
Could anyone indicate some example command to obtain data from tables and projections?
Thans in advance
Best regards

Vertica's SELECT statements are pretty standard SQL. It would be helpful to know the errors with your SELECT statements. I'm also not sure why you are starting your query with a leading backslash \ ?
Is there a specific reason you want to select data from a projection, rather than the underlying table and letting Vertica deal with it?
Hi ,
Your table (f its being created ) existing on some schema , to access the table , you need to specified the schema name as prefix to your query
Like select * from <Your Schema Name>.<table_name>
No avoid providing the schema as a prefix you can set you session search_path to reflect your schema name .
To see what is your existing search_path setting run the below command
try to select data dictionary
select * from v_catalog.projections - to observe all created projections
select * from v_catalog.tables - for tables
