问题 I need to find the missing records in a table. Table 1: ID|Num X|1 X|2 X|3 X|4 Y|1 Y|3 Y|5 Table 2: Num 1 2 3 4 5 I need to return: ID|Num X|5 Y|2 Y|4 I've found other solutions that would give me 5,2,4 but I need the ID associated with the missing record as well. 回答1: If you want the missing numbers, use a cross join to generate all numbers and then filter out the ones that exist: select i.id, t2.num from (select distinct id from t1) i cross join table2 t2 left join t1 on t1.id = i.id and t1

问题 I am trying to use AWS Glue for pulling data from my on-premise Netezza database into S3. The code I have written so far (not complete) df = glueContext.read.format("jdbc")\ .option("driver", "org.netezza.Driver")\ .option("url", "jdbc:netezza://NetezzaHost01:5480/Netezza_DB")\ .option("dbtable", "ADMIN.table1")\ .option("user", "myUser")\ .option("password", "myPassword")\ .load() print(df.count()) I am using a custom JDBC driver jar since AWS Glue does not support Netezza natively (the

问题 While researching an unrelated topic, I noticed the use of LIMIT ALL in an example on the IBM Knowledge Center website for Netezza. I'm unclear about the benefits of specifying LIMIT ALL here, and I am seeking clarification of the explanation (quoted below) from IBM. When might I need to specify LIMIT ALL? SELECT CASE WHEN rand = .1 THEN 'A' WHEN rand = .2 THEN 'B' ELSE 'C' END FROM (SELECT random() rand FROM tblA LIMIT ALL) subset From the IBM Knowledge Center: "The LIMIT ALL in the subquery

问题 I found that Netezza stores history of data in HISDB schema. Is it possible to join them so I would get history of which table has been modified by what procedure? Reason for this is I have DataStage job that loads Netezza table and after SQL command triggers procedures that add another set of data to that same table. I am in need to have all events documented for data lineage purpose. Current query I made returns procedure's call time. Issue is with joining to USER_HISTDB."$hist_table_access

问题 Any replacement or quick solution in NETEZZA for the Oracle function LISTAGG or WM_CONCAT ? SELECT deptno, LISTAGG(ename, ',') WITHIN GROUP (ORDER BY ename) AS employee FROM emp GROUP BY deptno; DEPTNO EMPLOYEE 10 JOHN,MICHEL,SAM 20 PHILIP,FORD,SCOT,SUNNY,JOSEPH 30 ALLEN,RUBY,BETTY,MARTIN,LEON,FRANK Thanks. 回答1: IBM provides a sample UDF/UDA that may meet your needs. Look for GROUP_CONCAT on this page. The direct link to source install file is here: group_concat.tgz. TESTDB.ADMIN(ADMIN)=>
