teradata

I have a TIMESTAMP column in a teradata table. I want to convert the timestamp to epoch value. Can someone shed some light on how to do this. This is a SQL UDF I wrote a few years ago. If you don't have access rights to create a function, you mighty ask you dab or simply cut & paste the calculation. /********** Converting a Timestamp to Unix/POSIX/epoch time Unix time: Number of seconds since 1970-01-01 00:00:00 UTC not counting leap seconds (currently 34 in 2010) The maximum range of Timestamps is based on the range of INTEGERs: 1901-12-13 20:45:52 (-2147483648) to 2038-01-19 03:14:07

For example a query : create table ; select xxx ; delete ; How to execute it in one session ? I saw one answer to a similar question about mysql. The trick is to turn on allow multiple queries String dbUrl = "jdbc:mysql:///test?allowMultiQueries=true"; For teradata specifically, what is the solution ? I tried String dbUrl = "jdbc:odbc:dsn?allowMultiQueries=true"; It is not properly working ? You're looking for a Multi Statement Request (MSR). It's simply sending multiple SQL statements to the server sepatarated by semicolons. But you can't mix DDL and DML in a single MSR because DDL must be

At the moment I have to rerun data selection query every month, where I create one base table. This table is named something like MyDB.MyTable_Current_Date , so for today that would be MyDB.MyTable_201811 using YYYYMM date format. Instead of having to set the name manually (using ctrl + h), I would like this to be done automaticaly. My goal is that I can open the SQL and run the query where the the table that is created is MyTable_YYYYMM . Note: eventually I want to also let the SQL run automatically every month, but for now this is a nice first step for my understanding. I made the below

Is there a way to raise errors inside of Teradata stored procedures? For example, I want to check if a table is empty. If the table is empty I wish to cause the stored procedure to error out with the error message "Table Empty". That will allow me to bubble up the error to the calling application. dnoeth TD13+ implements Standard SQL's SIGNAL/RESIGNAL . 来源： https://stackoverflow.com/questions/23399461/teradata-how-can-i-raise-an-error-in-a-stored-procedures

I successfully installed pyodbc module for python 2.7. However, when input the following code to connect to teradata, import pyodbc conn = pyodbc.connect('DRIVER={Teradata};DBCNAME=<tdwc>;UID=<UID>;PWD=<UID>;QUIETMODE=YES;') I got the following error; Traceback (most recent call last): File "", line 1, in pyodbc.connect('DRIVER={Teradata};DBCNAME=;UID=;PWD=;QUIETMODE=YES;') Error: ('00000', '[00000] [iODBC][Driver Manager]dlopen(/Library/Application Support/teradata/client/ODBC/lib/tdata.dylib, 6): Library not loaded: libtdparse.dylib\n Referenced from: /Library/Application Support/teradata

I need to insert the data from an excel sheet into a teradata table. and I need this to be done using a MACRO. I have data in an excel sheet like COL1 COL2 COL3 COL4 1 2 3 4 2 5 8 10 . . so on and i need to keep a button in the excel sheet and assign a macro to that button so that when i click the button the rows in the excel sheet should be inserted into a database table. The requirement is that I will send the empty excel sheet to the person, he will fill in the sheet with the data and he clicks the button in the excel and the data has to be inserted into the database table. I would prefer
