teradata

I'm trying to connect to Teradata in SAS. I set up an teradata ODBC on the machine. The assumption currently for me is that using ODBC is the only way for me to access the database. And here is the syntax of my connection command: Libname Teradata ODBC dsn = 'dsnname' uid = 'uid' pwd = 'pwd'; results: Error: The ODBC engine cannot be found. Error: Error in the LIBNAME statement. It keeps saying that the ODBC engine cannot be found. I'm really confused now. Is there anything wrong with the command? Or I have to do something else outside SAS? I check the licence Proc Setinit; result: SAS/ACCESS

I am trying to connect to teradata server and load a dataframe into a table using python. Here is my code - import sqlalchemy engine = sqlalchemy.create_engine("teradata://username:passwor@hostname:port/") f3.to_sql(con=engine, name='sample', if_exists='replace', schema = 'schema_name') But I am getting the following error - InterfaceError: (teradata.api.InterfaceError) ('DRIVER_NOT_FOUND', "No driver found for 'Teradata'. Available drivers: SQL Server,SQL Server Native Client 11.0,ODBC Driver 13 for SQL Server") Can anybody help me to figure out whats wrong in my approach? There's is

Sorry if the title is unclear. Basically I'm trying to select certain records from multiple tables then update a certain column value for the returned records. T-SQL Implementation UPDATE CUSTOMERS SET LIKES_US = 'Y' FROM RESTAURANT REST INNER JOIN CUSTOMERS CUST ON REST.LINK_ID = CUST.LINK_ID WHERE REST.REST_TYPE = 'Diner' AND CUST.LIKES_US IS NULL Oracle UPDATE (SELECT CUST.LIKES_US FROM CUSTOMERS CUST INNER JOIN RESTAURANT REST ON CUST.LINK_ID=REST.LINK_ID WHERE REST.REST_TYPE = 'Diner' AND CUST.LIKES_US IS NULL) NEW_CUST SET NEW_CUST.LIKES_US = 'Y'; I am tried doing the same thing in

I´m trying to connect R and Teradata using RJDBC. I´ve found this link that has an example using mysql, but i´m nos sure how to do the same with teradata. library(RJDBC) drv <- JDBC("com.mysql.jdbc.Driver", "/etc/jdbc/mysql-connector-java-3.1.14-bin.jar", identifier.quote="`") conn <- dbConnect(drv, "jdbc:mysql://localhost/test", "user", "pwd") I´ve downloaded this driver: http://downloads.teradata.com/download/connectivity/jdbc-driver But i´m not sure where i should reference the directory. I know there is a teradataR package out there , but i don´t know if it really works with the R 3.0.0.

This challenge is based on a real life use-case involving IP ranges. The solution I came with is based on the stack trace challenge I've presented previously. Each range start is treated as a PUSH operation and each range end + 1 is treated as a POP operation. The Challenge We have a data set of ranges where each range has a starting point, ending point and a value. create table ranges ( range_start int not null ,range_end int not null ,range_val char(1) not null ) ; A range can contain another range or follow another range, but cannot be equal to another range or intersect with another range.

My real life use-case was to merge nested ranges . I've drew some sketches and then I saw the resemblance between ranges starting and ending to stack PUSH and POP operations. I understood that solving this problem will also solve the original problem. The op column can actually be removed from the question. When val is NULL then it is a POP operation otherwise it is a PUSH operation. The Puzzle A table, stack_trace ,contains the following columns: i - Integer value that represents a point in time. op - 2 possible operations: I ("in"/"push") and O ("out"/"pop"). val - The value inserted by the
