There's a missing semicolon:

.BEGIN LOADING TABLENAME;
.RECORD 1;
.IMPORT INFILE name_arch FORMAT VARTEXT '09'XCV";

Hi Team,
I am able to execute the script successfully now but 60% of records go to error table2 and only 40% records inserted into actual table. I am not able to find any difference in records inserted into error and actual table.
Please help to identify the issue.

Your target table has a Unique Primary Index and your input has multiple records with the same PI value. For each PI value, one row is loaded and the others go to Error Table 2.

There are 3 locations. DBC.ColumnStats, DBC.IndexStats, and DBC.MultiColumnStats where the information for the stats used to get stored.i'm giving the below query to find that info regarding no of rows in a table or average row size  etc.
SEL* FROM DBC.COLUMNSTATS WHERE TABLENAME LIKE'%INFA_SOURCE12%'
This Query is not working for me .please correct me if i'm going wrong somewhere

What database version? Always use the "V" suffix version of DBC views (since TD12).
When you say it's "not working", do you mean that the query runs but returns no rows?

Teradata Syntax Trouble - response (9) by nhoigal

Hi all,
 
I would appriciate your help with the following code:

SELECT	vm.merchant_sf_id, vm.country_id,  vm.merchant_name_sf,
		vm.resp_employee_id, vm.main_category,
		vm.company_legal_name,
		emp.complete_name as "Owner_Name"
		,(Case when (count (vm.merchant_name_sf)in  (select merchant_name from sandbox.IL_inventory where inv.load_date > CURRENT_DATE -2 ))  >= 1 then 'TRUE' else 'FALSE'  end) as "Is_Live?"
FROM	dwh_base_sec_view.v_merchants_sf vm

join dwh_base_sec_view.v_employees as emp on emp.employee_id = vm.resp_employee_id
inner join sandbox.IL_inventory as inv on inv.merchant_name = vm.merchant_name_sf and inv.load_date > (CURRENT_DATE -2) 
where vm.country_id = 109

I get an error on the case line, for the operator >=
 
Any ideas?
 
Thanks :-)

Well, that's simply no valid SQL, I don't get what you're trying to do :-)
Show the working query without that CASE and explain what you're trying to do...

Hi Dieter,
 
The base query (without the case), shows a list of Merchants.
With the CASE I'm trying to find the merchant's name in another list, to see if he is currently active.
The CASE is a sort of lookup using count, with a result of TRUE if the merchant is Live at the moment, or FALSE if merchant is inactive.
 
Here is the code in Teradata without the CASE
 

SELECT vm.merchant_sf_id, vm.country_id,  vm.merchant_name_sf,

vm.resp_employee_id, vm.main_category,

vm.company_legal_name,

emp.complete_name as "Owner_Name"

 

FROM dwh_base_sec_view.v_merchants_sf vm

 

join dwh_base_sec_view.v_employees as emp on emp.employee_id = vm.resp_employee_id

inner join sandbox.IL_inventory as inv on inv.merchant_name = vm.merchant_name_sf and inv.load_date > (CURRENT_DATE -2) 

where vm.country_id = 109

If "active" is based on "inv.load_date > (CURRENT_DATE -2)" then you already retrun only active merchants. You might remove this conditon from WHERE and use:
 

,Case when inv.load_date > CURRENT_DATE -2
      then 'TRUE' 
      else 'FALSE' 
 end as "Is_Live?"

Or maybe you need somthing like this, check if any row for a given merchant quaifies as "active"

,Case when max(inv.load_date)
           over (partition by vm.merchant_name_sf)  > CURRENT_DATE - 
      then 'TRUE' 
      else 'FALSE' 
 end as "Is_Live?"

Are there any performance differences between running 1 backup job using 8 streams and 8 concurrent jobs using 1 stream?

Multiple sessions in Fastload - response (1) by cmedved

Fastload can only load one table per job. Increasing the sessions will generally increase the throughput of the load - the sessions can connect to multiple nodes to push data in parallel. All of the sessions are used to load the same table. The benefit of more sessions depends on the size of your system. The Multiload tool can load to multiple tables.
 
However, in general, you should use the newer TPT utilities (TPT Load, TPT Update). TPT Update is capable of loading to multiple tables.

You need to be aware of performance tail. If you run 8 jobs each with 1 parallel stream and 6 complete quickly, you will have a tail of 2 long running single stream jobs.
It will likely be better to run each single job with 8 parallel streams to ensure parallelism all the way through.
We also mix and match based on expected runtime with shorter jobs getting single streams and longer jobs getting parallel streams.
Of course, you have to ensure parallel streams are well tuned. Is 2 really faster than 1?

Each MLoad command must be preceded by a period and must end with a semicolon.
Each Teradata SQL command must not be preceded by a period and must end with a semicolon.
