Is possible to use like hint with subselect? , i mean i want to find all rows in table A that contains a word in a field(CALLED CONTENT) in table B, concretely in a field called content too, i show you the idea although the syntax is incorrect.
select
' + char (39) + @country + char (39) + ' as PAIS,
A.ID,
A.IDUSUARIO MSISDN,
NULL AS MSISDN_COD,
convert(char(19),A.FECHA_ALVENTO, 121) AS FECHA_MO_LOCAL,
NULL AS FECHA_MO_LOCAL_D,
Hope someone could help me in revising a long running query. Here is the query
select * from table1 where classid is null and productid not in ( select productid from table1 where classid = 67)
In here table1 could have several occurance of productid in which productid could have different classid. The possible values of classid are: NULL,1,2,3,67. Basically I am looking for all records whose classid is null but should never had an instance in table1 where its classid is 67.
Do you have something like a "join" statment that will only include all records in the left table that is not in the right table?
Hope someone could help me with this. Thanks in advance.

I am setting up filtered replication(tran repl) for a table that is 2+ TB in size. The filtered rows are less than 1% of total size.When I run the snapshot, sometimes it complete in 27 mins(I have already optimized the snapshot agent profile) and sometimes it runs for ever. Mostly it runs forever, so the chances of it finishing soon are really very less.I have infact created filtered index just to cater to the query in the filter i.e. on the filter predicates. The reason its flipping flopping is due to the incorrect plan that it chooses. I can force the right index and the filtered query runs just fine but. I cannot use the query hints when I am adding the filter in replication as its not allowed.
I then went ahead and created the plan guides to force the best plan. But the plan guide was not used because even if there is a single space in the actual query that replication runs in the background the plan guide will not be used(testing on plan guides has proved this). The query needs to be ditto same including whitespaces and carriage returns. I then ran profiler and found that there is a view that replication creates and executes to extract the filtered rows and BCP it. Got the text of the view and created the plan guide on it but it was still not used because sp_helptext output seems to be different than what is actually being fired by replication internally.
Further, I collected the verbose log with level 2 and tried to find out if the main query shows up there with no success.
(a) I can't use the plan guide because I do not know the exact syntax(I mean I have the query but I do not know the white spaces, carriage returns, etc) and
(b) I cannot use query hint while filtering the article.

I have two tables with the following relevant fields:
Apps appID appName
PBC pbcID appID appCT
These are joined on appID. appCT can be 1 of 2 values, either "PC" or "LA". So an example of a few records in PBC would be:
1 1 PC 2 1 LA 3 2 PC 4 2 LA 5 3 PC 6 4 LA ... ...
You can see that for each App, in PBC there can be two related records - PC and LA. But for example, record number 5 is App 3 PC, but there is no App 3 LA. I am trying to build a select to tell me which Apps are not in PBC at all, AND which Apps only have either LA or PC, not both.
I'm working on a purchasing website for a store. A request has many line items, and a line item can have many products. One of the characteristics of the line item data table is a total price, calculated from multiplying lineitems.quantity and product.price.
INSERT INTO lineitems (request_id, quantity, product_id, total_price)VALUES (@rid,@quant,@pid,@totalprice)WHERE @totalprice = (SELECT products.price * @quant FROM lineitems, products WHERE lineitems.product_id = products.id) Visual Studio isnt accepting this. Is there a way to do this better?
How do you combine the following 2 updates into one Update statement (1 SUBSELECT statement)
Update SPLL_Policy SET SPLL_Policy.Prog_Year = (Select TOP 1 Prog_Year From SPLL_WinsPolicy_Input Where SPLL_WinsPolicy_Input.Policy_Number = SPLL_Policy.Policy_Number ORDER BY SPLL_WinsPolicy_Input.DATE_TIME_RECEIVED DESC)
Update SPLL_Policy SET SPLL_Policy.Prog_NAME = (Select TOP 1 Prog_Name From SPLL_WinsPolicy_Input Where SPLL_WinsPolicy_Input.Policy_Number = SPLL_Policy.Policy_Number ORDER BY SPLL_WinsPolicy_Input.DATE_TIME_RECEIVED DESC)
I have the following table: CREATE TABLE ITEMS ([ITEMID] int, [itRULE] varchar(1)) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (11, 3) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (12, 3) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (21, 2) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (22, 2) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (31, 1) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (32, 1) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (41, 0) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (42, 0)
-- Those works and gives me 11,12,21,22 SELECT ITEMID FROM ITEMS WHERE itRULE IN (2,3) SELECT ITEMID FROM ITEMS WHERE itRULE IN ('2','3')
-- This doesn't works declare @Rule varchar(10) set @Rule='2,3' SELECT ITEMID FROM ITEMS WHERE itRULE IN (@Rule) Any idea? I don't mind to change the data type if it works.
I have two tables in which I need to select data from and I don't know what construct to use. The two tables are SY and MV. SY contains stocks and MV contains a log of all price changes of these stocks. I need to produce a report of price changes between the latest price and the previous price and take the difference between the two. I'm using MSSQL. Here are the important fields in my tables:
SELECT sy.syid, sy.sycode, mv.price, (SELECT TOP 1(mv.price) FROM MV, SY WHERE mv.syid = sy.syid AND mv.date < '8/27/2007' AND sy.ACTIVE = '1' ORDER BY mv.date DESC) AS lastprice, (mv.price - (SELECT TOP 1(mv.price) FROM MV, SY WHERE mv.syid = sy.syid AND mv.date < '8/27/2007' AND sy.ACTIVE = '1' ORDER BY mv.date DESC)) AS diff, (mv.price - (SELECT TOP 1(mv.price) FROM MV, SY WHERE mv.syid = sy.syid AND mv.date < '8/27/2007' AND sy.ACTIVE = '1' ORDER BY mv.date DESC)) / (SELECT TOP 1(mv.price) FROM MV, SY WHERE mv.syid = sy.syid AND mv.date < '8/27/2007' AND sy.ACTIVE = '1' ORDER BY mv.date DESC) * 100 AS percentdiff, mv.date FROM mv, sy WHERE mv.syid = sy.syid AND mv.date = '8/27/2007' AND sy.ACTIVE = '1' ORDER BY sy.syid, mv.date DESC
I have a query which contains 2 subselects joined with a union all. The select for each is just a count, so I'm only returning 2 rows. I then want to be able to perform a calculation between these 2 results... ie divide one by the other to get the percentage.
The only way I could think of doing that was make the whole query a subselect of another query where I could then perform the calculation in the new select statement, however it doesn't like this. I just get incorrect syntax near the closing bracket of the from section.
Any ideas? Thanks!

Hello,I have a problem with a subselect I use in a stored procedure:UPDATE #TEMP_TABLESET P_ID_1=(SELECT top 1 b.P_ID_1 from #TEMP_TABLE b whereb.ID=PARENT_ID),P_ID_2=PARENT_ID,P_ID_3=IDWHERE PARENT_ID IN (SELECT P_ID_2FROM #TEMP_TABLE b)So the subselect is (SELECT top 1 b.P_ID_1 from #TEMP_TABLE b whereb.ID=PARENT_ID), and it returns NULL. The cause of that is mostprobably the fact that I try to link ID from inner table b withPARENT_ID from the outer table. I thought it had to be done this way,but obviously not. Can somebody help me with this syntax problem?Thx,Bart
Not sure if this is the right group to post this to but.This is the current query that I have.select tableA.id,tableB.artist,tableB.image,from tableA,tableB wheretableA.image = tableB.image AND tableB.price >0 AND tableB.price < 20order by tableB.price DESC'What I need is, for each row returned I need information from a thirdand fourth table. tableC, and tableD.tableC has information ( the tableA.id = tableC.eventId) that I need toobtain tableC.accountId = tableD.accountId in order do select thethe binding information in tableD between a Vendor(name,address..etc..)and tableB.imageAny help would be greatly appreciated.
I have a stored procedure what produces N number of rows.The rows are ordered by a cataegoryType as followscatAcatBcatCWhat is needed to do on the C++ code side is break these out intotheir respective categories by iterating through the rows and checkingthe category type. Is there a way to let the DB do this via some sort ofsubselect on the rows returned via the stored procedure.Thanks in advance.
I have a sqldatasource, and on the selectcommand I'm trying to use a case statement with a subselect.

Background:I am currently working on a mission critical web based applicationthat is accessed 24 hours a day by users from just about every timezone. We use MS SQL Server as our database and we have lots ofproblems with time-outs. We used to have lots of problems with locksuntil my management decided that we would use the WITH (NOLOCK) hinton EVERY select statement and WITH (ROWLOCK) on EVERY updatestatement. I have argued since the beginning that the NOLOCK hintshould be the exception and not the rule. Meanwhile we continue tohave problems related to time-outs.Problem:I'm the one that they call when there are time-out errors.I am a programmer first and a DBA when I have to be. I'd really liketo hear from some of you who are the opposite. I realize that thereare many factors that contribute to slow response from a databaseserver (indexes, RAM, disk speed, etc.), but what I really need tohear from an expert is whether or not using NOLOCK on **EVERY** queryin a 30GB database that has 344 tables is a bad idea.Thanks in advance,Stephen McMahonJoin Bytes!
Help!I'm trying to understand the new ANSI join syntax (after many years ofcoding using the old style). I am now working with an application that onlyunderstands ANSI syntax so I am struggling.My first (old style syntax) SQL statement below produces 60 rows:SELECT A1.CONTACTID, A1.LASTNAME, A1.FIRSTNAME, A1.ACCOUNT,A6.CITY, A6.STATE, A1.WORKPHONE, A1.FAX, A1.EMAILFROM CONTACT A1,ADDRESS A6WHERE A1.ADDRESSID=A6.ADDRESSIDAND A1.CONTACTID IN(SELECT A4.CONTACTIDFROM CONTACT_LEADSOURCE A4,LEADSOURCE A5WHERE A4.LEADSOURCEID = A5.LEADSOURCEIDAND A5.DESCRIPTION = 'some_description' )AND A1.CONTACTID IN(SELECT A2.CONTACTIDFROM TICKET A2,ENROLLHX A3,EVENT A7WHERE A3.STATUS IN ('R', 'Confirmed')AND A2.TICKETID = A3.EVXEVTICKETIDAND A3.EVENTID = A7.EVENTIDAND A7.CODE IN('AHS00','AHS01','AHS02','AHS03','AHS04','AHS98',' AHS99'))ORDER BY A1.LASTNAME ASCI am trying to convert this to the newer ANSI sytax. My second SQL statementbelow produces 67 rows (duplicates):SELECT A1.CONTACTID, A1.LASTNAME, A1.FIRSTNAME, A1.ACCOUNT,A6.CITY, A6.STATE, A1.WORKPHONE, A1.FAX, A1.EMAILFROM CONTACT A1JOIN ADDRESS A6 ON (A1.ADDRESSID=A6.ADDRESSID)JOIN( SELECT C.CONTACTIDFROM CONTACT CJOIN CONTACT_LEADSOURCE A4 ON (C.CONTACTID= A4.CONTACTID)JOIN LEADSOURCE A5 ON (A4.LEADSOURCEID =A5.LEADSOURCEIDAND A5.DESCRIPTION ='some_description' )) AS C1 ON C1.CONTACTID = A1.CONTACTIDJOIN(SELECT C2.CONTACTIDFROM CONTACT C2JOIN TICKET A2 ON (C2.CONTACTID =A2.CONTACTID)JOIN ENROLLHX A3 ON (A2.TICKETID =A3.TICKETID AND A3.STATUS in ('R', 'Confirmed'))JOIN EVENT A7 ON (A3.EVENTID = A7.EVENTIDAND A7.CODE IN ('AHS00','AHS01','AHS02','AHS03','AHS04','AHS98',' AHS99')))AS C3 ON C3.CONTACTID = A1.CONTACTIDCan anyone shed some light on what I am missing?cheers,Norm
Hi all If i have a view: CREATE VIEW vw_Users AS SELECT * FROM Users WITH(NOLOCK)
Is it suggested to use nolock in views? And if i needed to use this view in stored procs is it then suggested to apply the nolock hint? CREATE PROC [dbo] .[usp_GetCompanyUsers] AS SELECT * FROM Companies WITH(NOLOCK) JOIN vw_Users WITH(NOLOCK) --<< ---is this suggested?
Hi All,I have a question about lock hint for you :If the first user currently run a select commandwith share lock and hold it. What kind oflock (lock hint) should be used by the second userin the select command (from the same table) so thatthis command will wait until the first user releasesthe lock ?I have tried using tablock, tablockx, xlock andupdlock hint in the select command for the seconduser, but it is not successful. Below is myunsuccessful test :The first user :Begin Transactionselect fprefix from ut1 where fprefix = '000'The second user :select * from ut1 with (tablockx)Please help meThanks in advanceAnita Hery*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
Can I use the NO Lock hint when running a SELECT against a view that points to another server? Will the no lock "travel" to the other server through the view?
I need to get back the actual characters (without trailing blanks) contained in a char(43) field. So i tried: - substring(fieldname,1,len(fieldname)) which yields a 43 char column - using a variable that contains the actual length in substring(fieldname,1,@nchar)) the same. - tricking by concatenating the resulting string with a dummy like "" didn't work either. So apparently I am at a dead end. Anybody a clue, hint or solution???? Thanks to all contributors
Is it possible to place an exclusive row lock when running a SELECT query by using a lock hint (or otherwise).
Basically, when a select statement is run against a table I don't won't any other users to read that row until it has been updated - at some later stage.
Any suggestions on whether this is possible would be welcome.
I want to implement the following pattern (pseudo-code follows):
[for index in x different databases, where x is rather big]
create database MyDatabase_#{index}_Temp launch a dedicated ssis package on this database if I detect no error, proudly rename MyDatabase_#{index}_Temp to MyDatabase_#{index}_Last_Known_Good (drop the last_known_good first if it exist)
Later on, a consolidation process collect the data in Last_Known_Good versions of the databases.
My question: what is the simpliest way to achieve the rename operation (step 3) ?
I have tried an "alter database #{old_database_name} modify name = #{new_database_name}", but it works only once: once renamed, the database keeps the old mdf and ldf filenames, and the next create database will choke on this.
I have also tried to rename the logical filenames with ALTER DATABASE XXX MODIFY FILE (NAME = YYY, NEWNAME = ZZZ) but it doesn't work either.
I'd like to avoid specifying absolute mdf and ldf filenames myself, is it possible ?
An interesting discussion yesterday. One of the programmers asked about the use of the NOLOCK optimizer hint with an iterator table aka table of numbers. His comment was that this optimizer hint was not efficient. Rather than give a knee-jerk response I thought it would be better to ask. The main circumstance is that the iterator table is completely static with a fill factor of 100%. My purpose is to eliminate lock contention if I can.
Are there reasons to not use the NOLOCK hint in this case to potentially improve performance?
My God! What happens if I miss a step, or put it in a different order??? I know I can specify ORDER BY StepID, but what about a missing step? I do have "missing ranges" script, but posting questions filtered through the script process may become a full-time job in itself...What to do, what to do...
Hi All,I want to lock 2 tables on 2 servers using TABLOCKXhint. These tables function as semaphores in myapplication. It means when the tables are lockedthen other users will not be able to access themand automatically they can not continue their works.I have tried using the following code, but itdoes not work. I always got the error :"Cannot specify an index or locking hint fora remote data source" on the select command.begin transelect * from server1.accounting.dbo.semtabwith (tablockx) where fprefix = '000'select * from server2.accounting.dbo.semtabwith (tablockx) where fprefix = '000'--commit tranThe error will disappear if I remove the servername, like this :select * from accounting.dbo.semtabwith (tablockx) where fprefix = '000'But, it does not meet my requirement.It only locks one table on one server(default).Please help meThanks in advanceJohn S.*** Sent via Devdex http://www.devdex.com ***Don't just participate in USENET...get rewarded for it!
Hello! I would like when I compare query plans to be able to compare 2 queries where the 1. is the "normal" version and the 2. the version where I forced compiler not to use a specific index (i don't want to force at table scan, so hint index(0) can't be used).
The only way I see how I could achieve something similar is to to drop the index and compare response time before and after. But building index could be time consuming...
Is it possible?
