I have data such as the following:
Field 1 (unique ID)     Date/time                       
1                               1/1/2016 01:05:09
2                               1/1/2016 01:05:09

/*I have two views in a company’s HR database I am pulling from. 

One gives a list of hiring actions. The first time an employee is hired, they’re given a sequence of 1. Each time after they’re given a sequence of 2, 3, 4 and so on.

The second view I’m querying has similar information for employees who were terminated. 

Teradata partitioning was originally released in V2R5.0. This presentation reviews partitioning and the changes to this feature (from DPE to columnar) that have occurred over the last twelve years.

Hi all,
I was extending the partition of some tables to host the 2015 and I have notice this strange behavior.
I have this table called Table1

Posted this on latest Paulsinclair blog post (2012) but I guess I'll it a try here :
Hi, I have a question about partition elimination in 14.00(.06.09) with a table partitioned on a timestamp column.
I've prepared 3 cases studies but first of all we need a materialized calendar table :

All of our tables have effective start and end date columns (EFF_STRT_DT, EFF_END_DT).  We want to create date partitions on some of our larger tables, and our fist instinct is to create the partition on EFF_END_DT, because we set that date to '9999-21-31' to represent "active" rows in our data warehouse.

Hi All,
I am aware that order of columns in defined PI doesn't matter.
But if we have multilevel Partition defined on the table and we are including the partitioning columns as a part of PI, does it matter in anyway how the PPI columns be included in the PI of the table.
I hope I made myself clear.

I'm new to Teradata and have a question on creating a table with a CPPI.
I have a table with a few hundered million rows. I want to create partitioning on a column called SAP_CODE whose structure is always four digits. The first digit is alphanumeric the last 3 digits are numeric, e.g. S001, M123, Z012.

I've just started playing around with column partitioning in R14. I created a table using a recent example that Paul Sinclair put into a recent Teradata Magazine article:


I have a tableA with partition given below,



sys =  1,

sys=   2,

sys=   3


cyc =  1,

cyc=   2,

cyc=   3 




All All,

I have a PPI table paritioned by end_dt

Accurately identifying how much a table has grown since statistics on a column were last collected is an important prerequisite for the statistics extrapolation process.  Once table growth has been detected, then stale statistics can be adjusted accordingly.  Extrapolations based on table growth will be be more accurate if statistics are being regularly collected on the system-derived column PARTITON, whether or not a table is partitioned.


Is there any way to partition directly on a small (ie. CHAR(3)) character column, without defining a CASE_N or RANGE_N for the column (ie. partition on all unique values of the column)?

What is the best way to extract the output of the 'Help statistics DbName.TblName column Partition;", for the purpose of extracting the value of the column 'Number of Rows'. If you have attempted this through SQL, please share your thoughts. What I've already have in place is the following methodology...
Run 'Collect Statistics on DbName.TblName Column (Partition);
Run 'Help Statistics DbName.TblName Column (Partition);' through BTEQ with SideTitles on

Is there any other way of reliably tell the optimizer to use the PPI other than hard-coding the minimal/maximal value (date) in a following case?

Here is a DDL for a big table with customer transactions:

PRIMARY INDEX NUPI_txn ( transaction_id )
INDEX NUSI_customer_id( customer_id)
