Direct Discovery

Anonymous — Tue, 18 Dec 2012 12:25:20 GMT

Hello Everyone,

My questions goes to new functionality of Direct Discovery (QV 11.2).

Is it possible to load more then one table like this?
Is it possible to make WHERE limitations to source data while using DIRECT?

I tried like this - and third statement failed (it fails even when I remove WHERE clause). It loads only tableA.

ODBC CONNECT TO ODBC_Teradata (XUserId is zyzyryxy, XPassword is blablablasimple);
DIRECT SELECT column_a, column_b IMPLICIT column_c
FROM schema.tableA;
DIRECT SELECT column_a,column_d IMPLICIT column_e
FROM schema.tableB 
WHERE date_of_day > date - 1;

Thanks in advance for info.

Best regards,

Paweł

Hi Paweł,

As far as I know, only one direct discovery table is allowed per load script / QVW file for the time being, so it makes sense that the second throws an error. You should use two different QVW applications if you want to use those two queries.

Hope that helps.

Miguel

Use view at db side. Create common structure and provide data source indicator on result data set. Passing parameters value of particular table get data direct from db and draw what you want.
