问题 I am doing some calculation but my calculation is off because my date field is showing the time-stamp and i only want to use as Date only when i am doing the calculation. How can i just ignore the minutes and just use the date when doing the calculation? Here is what i have: SELECT EF.DSCH_TS, CASE WHEN EXTRACT (DAY FROM EF.DSCH_TS - EF.ADMT_TS)>=0 THEN 'GroupA' END AS CAL FROM MainTable EF; 回答1: You may want to consider rewriting your case statement to return an interval. This will allow for

问题 Is there a query I can write to search all the column names for a particular database in Netezza? 回答1: Within the same database you can use the following query: select * from _v_odbc_columns1 where column_name like '%columnname%' or a less Netezza specific query select * from information_schema.columns where column_name like '%columnname%' 回答2: You would access something similar to an information_schema. Column Name, %COW%', would use % as a wildcard...gathering any column that has 'COW' in

问题 I have extended ascii chars in Oracle table data which I am able extract to a file using sqlplus with the \ escape character prefixed. I want to use nzload to load the exact same data into a netezza table. nzload adds a couple of extra bytes when it encounters this char seq (c2bf) in the extracted file data: echo "PROFESSIONAL¿" | od -x 0000000 5052 4f46 4553 5349 4f4e 414c **c2bf** 0a00 after nzload: echo "PROFESSIONAL¿" | od -x 0000000 5052 4f46 4553 5349 4f4e 414c **c382 c2bf** on the

问题 It appears that the lack of support for enforcing 2 basic constraints (unique and foreign key), is a reason for loss of many man-hours debugging and troubleshooting difficult problems. What starts as a trivial, easy-to-fix problem (dup rows /inconsistent primary-detail tables) goes un-noticed, grows and raises complex edge-scenarios in our application, or even in our hardware (e.g. self-join with dups can cause inflation and storage exhaustion). Netezza serves multiple purposes in our

问题 I have a table with the following columns in a Netezza Database Id field1 field2 1 0.9 sum(field1)/0.9 2 1.7 sum(field1)/1.7 3 6.9 sum(field1)/6.9 4 0.4 sum(field1)/0.4 5 0.2 sum(field1)/0.2 6 2.8 sum(field1)/2.8 7 7.0 sum(field1)/7.0 The field2 column is to be generated and will hold values as shown in the table. For this example the sum of field1 is 19.9 . Also the field1 values will change frequently. Please help with a query that will help calculate the field2 value also the values are in

问题 Suppose I have a table: HH SLOT RN -------------- 1 1 null 1 2 null 1 3 null -------------- 2 1 null 2 2 null 2 3 null I want to set RN to be a random number between 1 and 10. It's ok for the number to repeat across the entire table, but it's bad to repeat the number within any given HH. E.g.,: HH SLOT RN_GOOD RN_BAD -------------------------- 1 1 9 3 1 2 4 8 1 3 7 3 <--!!! -------------------------- 2 1 2 1 2 2 4 6 2 3 9 4 This is on Netezza if it makes any difference. This one's being a

问题 This mail is to discuss on a use case, on which my team is working. It's to export metadata and data from a HIVE server to RDBMS. On doing that, export to MySQL and ORACLE is working good, but export to Netezza is failing with error message: 17/02/09 16:03:07 INFO DAGScheduler: Job 1 finished: json at RdbmsSandboxExecution.java:80, took 0.433405 s 17/02/09 16:03:07 INFO TaskSetManager: Finished task 0.0 in stage 3.0 (TID 3) in 143 ms on localhost (1/1) 17/02/09 16:03:07 INFO TaskSchedulerImpl

问题 In Netezza, GROUP_CONCAT function does not support ORDER BY, it uses its own internal order by, which is order by the column you use as parameter. SELECT 'GROUP BY '||TOOLKIT.SQLEXT.GROUP_CONCAT(PRIMARY_KEY, ', ') AS GROUP_BY FROM ( SELECT 1 AS SEQ, 'DATA_DATE' AS PRIMARY_KEY UNION ALL SELECT 2 AS SEQ, 'ACCT_ID' AS PRIMARY_KEY ) S; This will return: GROUP_BY GROUP BY ACCT_ID, DATA_DATE But how to get result order by SEQ instead of PRIMARY_KEY to get result like this: GROUP_BY GROUP BY DATA

问题 I am trying to do a incremental load from Sql server 2008 to Netezza (Nps6) using SSIS. Netezza 5.x version OLEDB driver used. I am using Table or View - Fast Load option with Maximum insert commit size = 0 . Here I am trying to insert few thousands of records to a Netezza table. This destination table contains millions of records. This Data flow task was taking a hours to complete. When I looked into the Netezza Administrator Active Queries I could see that a query like below was the problem

问题 I am trying to output some files using NZSQL CLI but not able to output as tab delimited files. Can somebody who has worked on NZ share your thoughts on this below command. Tried so far :- nzsql -o sample.txt -F= -A -t -c "SELECT * FROM DW_ETL.USER WHERE datasliceid % 20 = 2 LIMIT 5;" 回答1: To specify tab as the delimiter use $ in conjunction with the -F option. nzsql -o sample.txt -F $'\t' -A -t -c "SELECT * FROM DW_ETL.USER WHERE datasliceid % 20 = 2 LIMIT 5;" This is documented in the nzsql
