问题 I have xml documents stored as text in a VARCHAR column. I'd like to convert the text to XML documents in order to perform XQUERY selects on the documents. An example document looks like: <a> <b foor="bar"/> <c/> </a> My query looks like: SELECT XMLQUERY('//c' PASSING XMLCAST('<a><b foor="bar"/><c/></a>' AS XML)) FROM SYSIBM.sysdummy1 But instead of returning a element I get the following error message: SQL Error [10507]: The Context item in an axis step must be a node. SQLCODE=-16012,

问题 Topic says it all. I'm trying to do some magic, via a function, that turns a second integer into a string "DD:HH:MM:SS". Snip input: 278543 output: "3D 5H 22M 23S " What I'd like to do, more gracefully if possible, is pad the numbers (So that 5M shows as 05M) and right align them so that "3D 5H 22M 23S " is " 3D 5H 22M 23S" instead. edit: Latest cut that seems to work. Would love to have it prettier, but this definitely works as far as I can tell: CREATE FUNCTION DHMS(secondsElapsed INT)

问题 I have two db2 tables on the mainframe 'old' and 'new'. These tables have 1 billion records each as of now with 70-80 columns. These tables are getting populated from two different systems, so the table structure is not identical, i.e. there are some differences in the columns with both tables sharing some common columns which have to be compared for different data values. for example : OLD id A B C 1 x y z 1 x y z 3 m n o 4 e f g NEW id B C D E 1 y a a b 1 y a a b 2 n o c d 4 g g l m So in

问题 Let's say I have a table T_SWA.This is my prepared statement. Select version From (Select id, version, creator, created_date ROW_NUMBER() OVER(order by created_date) cnt From T_SWA Where cnt=3 and id=35); I need to select the 3rd recent version from the T_SWA table. Can anyone suggest a replacement for this query without using ROW_NUM() and OVER() functiions? 回答1: First take the three most recent and then from those three take the first. select id, version, creator, created_date from ( select

问题 I currently have a query that reads from a table which is written to daily, so I have totals for every day. What I'm trying to do is modify this query so that I can use days of the week as an aggregate, if that makes sense.
