问题 I have a problem with a ORACLE Procedure, it seems that SELECT SUM ignores my WHERE clause, and Sums up ALL of the columns instead of only those that i want to (deptno). However if i use one of this functions like this for example : select SUM(SAL) AS SALSUM FROM SCOTT.EMP WHERE SCOTT.EMP.DEPTNO = 10; It displays the proper SUM. What may be the problem? Thanks for help. CREATE OR REPLACE PROCEDURE PROCEDURE1(numerdept IN number, money OUT number) IS SALSUM NUMBER; COMMSUM NUMBER; WYJATEK

问题 What I'm trying to do is take a record that looks like this: Start_DT End_DT ID 4/5/2013 4/9/2013 1 and change it to look like this: DT ID 4/5/2013 1 4/6/2013 1 4/7/2013 1 4/8/2013 1 4/9/2013 1 it can be done in Python but I am not sure if it is possible with SQL Oracle?

问题 SELECT round(COUNT(dmd_1wk),2) AS NBR_ITEMS_1WK FROM table; Field dmd_1wk has so many zeros in it. How do I Count the non zero values? 回答1: Methinks bluefeets answer is probably what you are really looking for, as it sounds like you just want to count non-zeros; but this will get you a count of zero and non-zero items if that's not the case: SELECT ROUND(SUM(CASE NVL(dmd_1wk, 0) = 0 THEN 1 ELSE 0 END), 2) AS "Zeros", ROUND(SUM(CASE NVL(dmd_1wk, 0) != 0 THEN 1 ELSE 0 END), 2) AS "NonZeros"

问题 In my application, I have a connection pool that I use to obtain connections to Oracle database. I need to execute statements that call stored procedures that might affect the database session context/variables so that these changes affect only the current use of the connection. When I close the connection and obtain another connection from the pool, I want it like a new connection/session at which the effect of the procedure doesn't exist. Unfortunately, this doesn't happen. So I obtain a

问题 I set a numeric primary key, and an alphanumeric field that stores truck FINS, which is just a random mix of numbers and letters.
