What exactly is happening when a query is sent using the N in front of
the string to be found?
Under what conditions would someone use the N' in a query?
I have been testing out some chinese text. I set up some fields of
nVarchar, nText and it works with an N. Without the N, it wont work.
N also works with fields of varchar and text for english.
Would this ever cause a problem to a query depending on how the
machines regional settings are set? Why not just put N in all of the
queryies?
If anyone has some ideas, I would be grateful for any and all
information about the N.
I have a Log table which records items found on library shelves during a shelf scanning process. Each time a shelf is scanned all the items found are recorded in the log table and the ScanCount value is incremented (per shelf). This means that if I get the records with the highest available ScanCount value for each ShelfID, then I would have the most up to date picture of my library.
From this sample data I would like to return the latest rows (max scan count) for all shelves (which would be LogID: 7,8 (shelf A) 3,4 (Shelf B) 5,6 (Shelf C):
LogID ShelfID ScanCount ItemName 1 A 1 Dave 2 A 1 Alan 3 B 1 Mike 4 B 1 Andy 5 C 1 Mary 6 C 1 Mark 7 A 2 Sam 8 A 2 Will
I'm not sure how to do this - presumably with an inner select? Could someone help? thanks
This may be a more general question but I love SQL Server so Ill pose it here. I couldnt find this answer on google so that why Im asking. I was never taught (or I was too high to retain the info) form college in my one DB class.
What are the performace impacts, if any, on doing a "SELECT * FROM table" vs. "SELECT each, column, called, out, but, not, all, of, them FROM table" ?
--create a temp table like: select * into #tmp from (select 1 as ID union all select 2 union all select 3 union all select 4 ) as A
-then run this query: select B.ID,isNull(B.GID,0) as GID from (select #tmp.ID,A.GID from #tmp left outer join (select ID,1 as GID from #tmp where ID in (2,4)) A on #tmp.ID = A.ID ) as B
--I thougth it should return: 10 21 30 41 --but it actually returned: IDGID 11 21 31 41 --if I change GID value in '...(select ID,1 as GID from #tmp where ID in (2,4)...', for example 2, then it return: IDGID 12 22 32 42
Hi,I am getting errors in the following... Is it even possible to join onCONTAINS?SELECT ListA.ContentFROM ListA LEFT OUTER JOIN ListBON CONTAINS(ListB.Content, ListA.Content)WHERE ListB.Content IS NULLThanks!
where I can look for the user,who execute this statment?
It was 6.02.2007 or 7.02.2007. All users connect using SQL Serwer Authentication. It is test database and from 1 to 3 users connect to it, and submit not more then 10 SQl statmant per day.
Howdy,Is it okay to use a literal value with the IN clause. E.g.SELECT somefield, anotherfield.....WHERE ...etc.AND 1234 IN (SELECT userid FROM tblUsers)I was told it wasn't valid, but I'm pretty sure it worked for me. Justseeking clarification.cheers,
. . . UPDATE Employees set depth=0, hierarchy=NULL
UPDATE Employees set depth=1, hierarchy=right(@MaxPadLength + CAST(Employees.Parent AS varchar(255)),@DisplayPadLength) where Child = Parent
WHILE EXISTS ( SELECT * FROM Employees WHERE Depth=0 ) . . . I have many tables that have the same structure as the Employees table but have different names. I would like to pass the PS a paramater with the table name I want to process. My question is what is the correct syntax to use a parameter in place of the literals for the table name?
I am trying to extract the month from a date field, and I am able to get the integer for the month, however, when I try to convert the integer to the literal, e.g. 3 to March, I am having issues.
I have a field called PROCES, which represents a date processed, which is numeric(8).... i.e. 20061231.
I am using: SELECT datepart(mm,cast(convert(char(8),PROCES)as datetime)) which gives me the correct integer.
When I try: SELECT datename(mm,datepart(mm,cast(convert(char(8),PROCES)as datetime)))
I am trying to insert some values retrieved from textboxes into an Access DB using ASP.NET. When I try to run this code I get an error reading "Too many characters in character literal". What does this mean? Also, how do I break new lines, does way this look ok?
Hi, I want to convert literal string to unicode before insert into the database. and after insertion i want to retrive this value from data base and convert back to literal string. pls tell me how to incode and decode literal string to unicode and from unicode to literal string.
When a report is exported to Excel, the footer is set to a literal "page 1 of 1" even though it's specified as
="Page " + CStr(Globals!PageNumber) + " of " + CStr(Globals!TotalPages)
in the rldc report definition.
Hence, if you print from Excel every page has the 'page 1 of 1' footer. Not very useful.
Is there a way to either suppress the output of the footer (only when going to Excel cause you need it when exporting to PDF) -or- get it to generate the correct excel footer of 'page 1 of ?'????
I'm struggling with the syntax for qualifying an openquery's results with a where clause. I copied this from examples on the web but get the error incorrect syntax near '32810'.
declare @sysid varchar(50) = '32810C534D01C920E7CB07EBC0A80122' declare @sql varchar(500) = 'select * from OPENQUERY(WAREHOUSE,''select * from xxx.yyyy where sys_id = ''' + @sysid + ''''')' exec(@sql) selecting @sql it looks like select * from OPENQUERY(WAREHOUSE,'select * from xxx.yyyy where sys_id = '32810C534D01C920E7CB07EBC0A80122'')
I'm a newbee to SQL Server. I have a very simple question to you experts: How should I code a literal of the "datetime"-Datatype? For Example in the VALUES-clause of an SQL-statement. I have tested several "formats" ('20.04.2006 11:15:00' with an 4-digit year enclosed in single apostrophes) but all i earned is an exception!
Any help very appreciated!
Thanks in advance and best regards

PS.: I'm using a german-localized database (thus the date-format dd.MM.yyyy).
The proc below does two queries that are functionally identical. The only difference is that one LIKE 'foo%', and the other uses LIKE @searchText, where @searchText = 'foo%'.
But the first does an index seek, and the second does an index scan -- and it makes a big difference in performance. (Timing stats are below.)
How can I make the second query seek instead of scanning?
From what I've read, SQL Server is supposed to do a phrase match when you do a full text search that contains quoted literals. So, for example, if I did a full text search on the phrase "time out" and I put it in quotes, it's supposed to search for the full phrase "time out" and not just look for rows that contain the words "time" or "out." However, this isn't working for me.
Here is the query that I'm using :
SELECT * FROM Content_Items ci INNER JOIN FREETEXTTABLE(Content_Items, hed, '"time out"') AS ft ON ci.contentItemId = ft.[KEY] ORDER BY ft.RANK DESC
What's it's doing is this : it's returning a bunch of rows that have the words "time" or "out" in the column called hed. It's also returning rows that have the full phrase "time out", but it's giving those rows the same rank as rows that only contain the word "time." In this case, that rank is 180.
Is there anything else I should be doing in my query, or is there some configuration option I should have turned on?
The Web Service Task seems to support calling methods using parameters but not (as far as I can see) using the Document/Literal calling convention. Is this correct? Is this likely to change in the future?
Hi, I have a datareader component of which i am dynamically setting its sqlcommand statement with expression (click the background of dataflow > properties > expressions). Now my sql select statement has about 600 fields so that makes my expression statment "select field1, field2, .....from table1 where field2 >=" + @[User::dateforfield2] but when i evalute the expresssion (which is right), i get the error: A string literal in the expression exceeds the maximum allowed length of 4000 character and i think its because of the fields in my select statment causing my string literal to grow more than 4000 characters. Is there any way to increase the max string literal for expressions. Please help.
how SQL 2012 would treat a literal string for a comparison similar to below. I want to ensure that the server isn't implicitly converting the value as it runs the SQL, so I'd rather change the data type in one of my tables, as unicode isn't required.
Declare @T Table (S varchar(2)) Declare @S nvarchar(255) Insert into @T Values ('AR'), ('AT'), ('AW') Set @S = 'Auto Repairs' Select * from @T T where case @S when 'Auto Repairs' then 'AR' when 'Auto Target' then 'AT' when 'Auto Wash' then 'AW' end = T.STo summarise
in the above would AR, AT and AW in the case statement be treated as a nvarchar, as that's the field the case is wrapped around, or would it be treated as a varchar, as that's what I'm comparing it to.
Hello all, I have two mult-value parameters in my report. Both of them working with selecting one or more values. But, when I test using "(Select All)" values for both parameters , only one parameter works. The "available values" for these two parameters are both from the data set.

I have a problem where my users complain that a select statement takes too long, at 90 seconds, to read 120 records out of a database. The select statement reads from 9 tables three of which contain 1000000 records, the others contain between 100 and 250000 records. I have checked that each column in the joins are indexed - they are (but some of them are clustered indexes, not unclustered). I have run the SQL Profiler trace from the run of the query through the "Database Engine Tuning Advisor". That just suggested two statistics items which I added (no benefit) and two indexes for tables that are not involved at all in the query (I didn't add these). I also ran the query through the Query window in SSMS with "Include Actual Execution Plan" enabled. This showed that all the execution time was being taken up by searches of the clustered indexes. I have tried running the select with just three tables involved, and it completes fast. I added a fourth and it took 7 seconds. However there was no WHERE clause for the fourth table, so I got a cartesian product which might have explained the problem. So my question is: Is it normal for such a type of read query to take 90 seconds to complete? Is there anything I could do to speed it up. Any other thoughts? Thanks
Hey guys i have a stock table and a stock type table and what i would like to do is say for every different piece of stock find out how many are available The two tables are like thisstockIDconsumableIDstockAvailableconsumableIDconsumableName So i want to,Select every consumableName in my table and then group all the stock by the consumable ID with some form of total where stockavailable = 1I should then end up with a table like thisEpson T001 - Available 6Epson T002 - Available 0Epson T003 - Available 4If anyone can help me i would be very appreciative. If you want excact table names etc then i can put that here but for now i thought i would ask how you would do it and then give it a go myself.ThanksMatt
