问题 A while I have posted an answer to this question PostgreSQL multiple criteria statement. Task was quite simple - select values from one table if there is no corresponding value in another table. Assuming we have tables like below: CREATE TABLE first (foo numeric); CREATE TABLE second (foo numeric); we would like to get all the values from first.foo which doesn’t occur in the second.foo . I've proposed two solutions: using LEFT JOIN SELECT first.foo FROM first LEFT JOIN second ON first.foo =

问题 There are two tables Document and DocumentPos . In Document there is column GUID and in DocumentPos is column DocumentGUID which refers to table Document . I want to have every row in DocumentPos where its DocumentGUID has now row in Documents' GUID . I've this query which returns 0 rows: select * FROM Document d, DocumentPos dp WHERE d.GUID = dp.DocumentGUID AND dp.DocumentGUID NOT IN ( SELECT d.GUID FROM Document ) But when when I execute select * from documentpos it returns for example a

问题 I need a list of users in one database that are not listed as the new_user_id in another. There are 112,815 matching users in both databases; user_id is the key in all queries tables. Query #1 works, and gives me 111,327 users who are NOT referenced as a new_user_Id. But it requires querying the same data twice. -- 111,327 GSU users are NOT listed as a CSS new user -- 1,488 GSU users ARE listed as a new user in CSS -- select count(gup.user_id) from gsu.user_profile gup join (select cud.user

问题 I would like to use not in statement with a data.frame in dplyr but it is not working. I would like to exclude values from a data.frame since I do have huge week numbers. Below is an example df1 = data.frame(week=c(1,2,3,4,5,6),sales=c(10,24,23,54,65,45)) week_e=data.frame(week=c(2,5)) so I would like to exclude weeks in week_e data frame from df1 and below is code and it is not working. Please help! Thank you. df1 %>% filter(!week %in% week_e) week sales 1 1 10 2 2 24 3 3 23 4 4 54 5 5 65 6

问题 How do you combine NOT IN and LIKE ? Let's assume we have a table that contains a column of names (something like 'blue cheese', 'gouda cheese' and so on) and I want to select all the names that doesn't contain 'cheese', 'milk', 'meat'. As far as I understand to look for something that is not in an array of strings you use NOT IN and the pass the strings SELECT names FROM some_table NOT IN('cheese','milk','meat'); but how do I pass LIKE '%cheese%' to it? 回答1: The construct LIKE ANY (ARRAY[...

问题 Trying to fix someone else's code. The NOT IN kills performance. I took it out and replaced with Not Exists and I'm getting different results. The commented out not in is just above my not exists. Anyone see anything stupid I'm doing here? IF @ProcessComplete = 1 BEGIN -- PRINT 'Group-Complete' INSERT INTO @ProcessIDTable SELECT DISTINCT(ProcessID) FROM vPortalInbox WHERE GroupUserIDs LIKE '%,' + CAST(@UserID AS VARCHAR(MAX)) + ',%' AND StepOwnerID IS NULL --AND ProcessID NOT IN (SELECT

问题 I have a query which is not working as expected Q1: SELECT id, name FROM vw_x WHERE id NOT IN (select pid from table_x) GROUP BY id, name Having max(c_date) > GETDATE() Q2: SELECT id, name FROM vw_x GROUP BY id, name Having max(c_date) > GETDATE() Q1 is not returning anything even though i know those ids are not in table_x Q2 runs correctly without NOT IN What could be wrong with my query? 回答1: you have a NULL value in the table try this SELECT id, name FROM vw_x WHERE id NOT IN (select pid

问题 I have a long piece of PL/SQL which is working well except for one small part of the where clause. I'm expecting that one row should be returned but, because the fields the where clause checks are null, the row is not being returned despite meeting the criteria. I read a very good note here : http://jonathanlewis.wordpress.com/2007/02/25/not-in/ It explains how Nulls affect NOT IN statements and I presume it's the same for NOT LIKE as well. What I haven't been able to find is the comparable
