问题 I would like to create a SELECT query that results in a view that is 30 fields long and 1 record thick. 2 records if we're counting the title. The specific part of the larger query in question is: WHERE CAST(EVENT_TIMESTAMP AS DATE) - CONTRACT_EFFECTIVE_DATE = 1 This produces the results desired - records where the days between EVENT_TIMESTAMP and CONTRACT_EFFECTIVE_DATE is 1. But I'd like this for 30 days. Something like: WHERE CAST(EVENT_TIMESTAMP AS DATE) - CONTRACT_EFFECTIVE_DATE = 1:30

问题 Can you please help me concerning this matter (I didn´t found it in the Teradata documentation, which is honestly little overwhelming): My table had this column -BAN DECIMAL(9,0)-, and now I want to change it to - BAN DECIMAL(15,0) COMPRESS 0.- How can I do it? What does COMPRESS constraint 0. or any other mean anyway? I hope this is possible, and I don`t have to create a new table and then copy the data form the old table. The table is very very big - when I do COUNT(*) form that table I get

问题 I am trying get the default database name from the connection for Teradata. I am using Teradata JDBC Driver 15.10.00.33. The following code gives me this abstract method error. Can anyone suggest me how I can get default database name using jdbc?

问题 Simple Problem: I want to connect my linux based C++ program to a Teradata database. How do I accomplish this? I searched the web but I only found some ADO and ODBC based solutions for .net or JDBC drivers. Is there any lib out there that can do the job on linux without ODBC and .net?

问题 I have a decimal(6,2) field storing data in seconds. I want those seconds to be converted in to HH:MM:SS. For ex: '19,500' seconds should be shown as 05:25:00 回答1: Assuming that the datatype is a typo (you can't store 19500 in a decimal(6,2)): col * INTERVAL '00:00:01' HOUR TO SECOND -- no fractional seconds col * INTERVAL '00:00:01.00' HOUR TO SECOND -- fractional seconds 来源： https://stackoverflow.com/questions/38521268/convert-seconds-to-hhmmss-in-teradata

问题 I have the following table.

The table below is what the desired end result would be. Animal Vaccine_Date Vaccine Dog 1/1/2016 x Dog 2/1/2016 y,z Cat 2/1/2016 y,z I have tried to create a volatile table to do so but I am not having any luck and I don't think Teradata

问题 I am trying to build an insert into statement that will include a URL string which has a valid "?" in it. I am using Teradata SQL Assistant (Windows XP) and it is trying to translate this into a parameter. Is there any way to override this and treat it as a character value? Example URL: https://www.location.com/livelink.exe?func=ll 回答1: Go to the Query tab on the Tools -> Options... page and uncheck the box labeled "Allow use of Named Parameters in queries". Here are the settings I use: That

问题 R3.0 is not compatible with TeradataR and there are no plans to update the package or release the source code. Does anyone have a code snippet that shows how to write a dataframe to a new or existing Teradata table? sql <- "CREATE TABLE teradata.aaa (yr BIGINT, ct BIGINT, tax BIGINT)" tbl <- sqlQuery(ch, sql) # Creates a table, works # What syntax to insert a dataframe 'myData' into this table? 回答1: Sadly, I learned that bulk uploads are not supported. I had to simply INSERT each line of the

问题 Is this valid ANSI SQL?: SELECT 1 AS X ,2 * X AS Y ,3 * Y AS Z Because Teradata (12) can do this, as well as this (yes, crazy isn't it): SELECT 3 * Y AS Z ,2 * X AS Y ,1 AS X But SQL Server 2005 requires something like this: SELECT X ,Y ,3 * Y AS Z FROM ( SELECT X ,2 * X AS Y FROM ( SELECT 1 AS X ) AS X ) AS Y 回答1: No, it's not valid ANSI. ANSI assumes that all SELECT clause items are evaluated at once. And I'd've written it in SQL 2005 as: SELECT * FROM (SELECT 1 AS X) X CROSS APPLY (SELECT
