Sorry guys, I had no idea how to phrase this one, but I have the following in a where clause: person_id not in ( SELECT distinct person_id FROM protocol_application_log_devl pal WHERE pal.set_id = @set_id ) When the subquery returns no results, my whole select fails to return anything. To work around this, I replaced person_id in the subquery with isnull(person_id, '00000000-0000-0000-0000-000000000000') . It seems to work, but is there a better way to solve this? It is better to use NOT EXISTS anyway: WHERE NOT EXISTS( SELECT 1 FROM protocol_application_log_devl pal WHERE pal.person_id =

This question already has an answer here: Check if something is (not) in a list in Python 2 answers I have two lists: mylist = ['total','age','gender','region','sex'] checklist = ['total','civic'] I have to work with some code I have inherited which looks like this: for item in mylist: if item in checklist: do something: How can I work with the code above to tell me that 'civic' is not in mylist ?. This would've been the ideal way to do it but I cant use it, don't ask me why. for item in checklist: if item not in mylist: print item Outcome: civic How about this? for item in mylist: if item in

I'm looking for the CouchDB JS view equivalent of the following LinQ query : var query = from f in context.Feed where !(from ds in context.DataSource select ds.Feed_ID) .Contains(f.ID) select f; Where DataSources have a foreign key to Feeds. In a word : get all Feeds not associated with a DataSource Thank you You can use the view collation to join feeds and data sources in map: function(doc) { if (!doc.type) return; if (doc.type == "feed") emit(doc._id, null); if (doc.type == "ds" && doc.feed) emit(doc.feed, null); } and reduce to filter those feed ids which have data source documents linking

I'm using Postgres with this query select * from Entity this_ where (this_.ID not in (null)) Why does this give me no results? I would expect to get all rows where id is not null with (this_.ID not in (1)) i get the expected results The result of [not] in (null) will always be null. To compare to null you need is [not] null or is [not] distinct from null select * from Entity this_ where this_.ID is not null If you want where (ID not in (1,null)) as in your comment you can do where ID is not null and ID not in (1) PostgreSQL uses NULL as undefined value. What you're asking is to return the

CREATE TEMP TABLE TMP_EMPLY_BRND AS ( Select EMPLY_SRRGT_ID, EMPLY_PRMRY_BRND_PRDCT_DPRTMNT_EFF_STRT_DT_KEY, EMPLY_PRMRY_PRDCT_DPRTMNT_GRP_SRRGT_ID, From (( (SELECT E.EMPLY_SRRGT_ID, E.EMPLY_PRMRY_BRND_PRDCT_DPRTMNT_EFF_STRT_DT_KEY, FROM INS_EDW_CP.EMPLY

I need to build a query that will show me records that are in Table 1, but that are not in Table 2, based on the make-model-serial number combination. I know for fact that there are 4 records that differ, but my query always comes back blank. SELECT * FROM Table1 WHERE MAKE+MODEL+[Serial Number] NOT IN (SELECT make+model+[serial number] FROM Table2) Table 1 has 5 records. When I change the query to IN , I get 1 record. What am I doing wrong with the NOT ? Dave Markle It's because of the way NOT IN works . To avoid these headaches (and for a faster query in many cases), I always prefer NOT

Could some one please provide how to write following sql query using joins. I do not want use not in as well as if possible I would like to replace where condition as well. SELECT d1.Short_Code FROM domain1 d1 WHERE d1.Short_Code NOT IN ( SELECT d2.Short_Code FROM Domain2 d2 ) I am using SQL Server 2008 This article: NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL: SQL Server may be if interest to you. In a couple of words, this query: SELECT d1.short_code FROM domain1 d1 LEFT JOIN domain2 d2 ON d2.short_code = d1.short_code WHERE d2.short_code IS NULL will work but it is less efficient than a
