I have a requirement like i need to convert a recursive CTE in sql server into netezza ! Will netezza even support Recursive CTE ? Can anyone help me on this ? Thanks in advance, Manirathinam. Recursive CTEs are not supported in Netezza as of version 7.2. If you can tell us what you are trying to accomplish in your particular case, we might be able to offer a workaround/rewrite. 来源： https://stackoverflow.com/questions/29358821/convert-a-recursive-cte-in-sql-server-to-netezza

I have data from a flat file that I am loading into netezza via nzload . Some of the field types are numeric however, the data received can sometimes contain invalid characters. How can i check to make sure that the data isnumeric in my import? I saw try_cast for T-Sql but didn't see anything similar in netezza. Netezza doesn't have an equivalent to try-cast , you can however test if the value is numeric a few different ways. If you have the SQL Extensions Toolkit installed you can use a regex function. sql_functions.admin.regexp_like(<Column Name>, '^[+-]?[0-9]*[.]?[0-9]*$') Otherwise you can

I am trying to load data from text file to External table in Netezza . Here is my command INSERT INTO XTABLE_DHARMESH SELECT * FROM EXTERNAL 'C:\Dhams\mergeresult.txt' USING (delimiter ',' REMOTESOURCE 'ODBC' LOGDIR 'C:\Dhams'); I am getting ERROR [08S01] Communication link failure. This error is occurring when I have 1 millions of records in file whereas it is working fine for 1000 records in my textfile. I have found in Windows 7 and Windows Server 2008 R2 TCP Chimney Settings were the culprit. http://blogs.dirteam.com/blogs/sanderberkouwer/archive/2008/05/15/backward-compatible-networking

I'm working in Netezza -- or, you know, pure data for Analytics -- nzsql, but I think this is an ANSI SQL question. The question is so basic, I don't even know how to search for it. CREATE TEMPORARY TABLE DEMO1 AS SELECT 'SMORK' AS SMORK, 'PLONK' AS PLONK, 'SPROING' AS SPROING; SELECT SMORK AS PLONK, PLONK, SPROING AS CLUNK, CLUNK FROM DEMO1; This returns 'SMORK, PLONK, SPROING, SPROING', which is to say, the query is fine reusing the CLUNK alias, but the PLONK alias is overwritten by the column from the source table. Now, if I really wanted the column from the source table, I could write

I have a Netezza query where I reference a couple of dates in a series of case statements. Instead of replacing all of these dates every time I'd like to declaire a variable at the beginning and use that throughout the query. In SAS I'd do it like this: %LET end_p = '31DEC2014'd; proc sql; create table want as select distinct id, sum(case when (INCUR_DT) >= (&end_p-30) and ip_op_cd = 'IP' then net_allow_at else 0 end) as ip_d_30, sum(case when (INCUR_DT) >= (&end_p-90) and ip_op_cd = 'IP' then net_allow_at else 0 end) as ip_d_90, sum(case when (INCUR_DT) >= (&end_p-180) and ip_op_cd = 'IP'
