I am having a hard time having restrictive matches on an equality select where nchar is involved.
The table is:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Download_Hash_Log](
[log_id] [int] IDENTITY(1,1) NOT NULL,
[hash_value] [nchar](16) COLLATE Latin1_General_BIN NOT NULL,
[log_date] [smalldatetime] NOT NULL,
CONSTRAINT [PK_Download_Hash_Log] PRIMARY KEY CLUSTERED
(
[log_id] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
There is exactly one row in the table. It has value 1234567890123456 for hash_value column.
SELECT *
FROM Download_Hash_Log
where convert(varbinary,hash_value) = convert(varbinary,N'1234567890123456')
returns the row - Good.
SELECT *
FROM Download_Hash_Log
where convert(varbinary,hash_value) = convert(varbinary,N'12345678901234')
doesn't return the row. Good.
SELECT *
FROM Download_Hash_Log
where convert(varbinary,hash_value) = convert(varbinary,N'123456789012345')
returns the row. WRONG.
SELECT *
FROM Download_Hash_Log
where convert(varbinary,hash_value) = convert(varbinary,N'1234567890123455')
returns the row. WRONG.
Please help me explain why the last 2 conditions are failing. Why is SQL doing a fuzzy match and returning the row even though it is literally different from the stored value? Is it ignoring the last byte?
I have a table Customer with column name "SerNo" the value of SerNo column is like below.

A bug in my front end application inserted a new line character in string values that were saved to a varchar field in the database. e.g. "This is a string" was modified to "This is a string" where represnts a new line character.
1) I want to write a SQL query to cleanse the data by replacing the new line characters in this field (say the field name is reason) with a single space.
2) I'd also like to be able to create a SQL query that allows me to specify such strings in the WHERE clause. e.g. SELECT * FROM table WHERE reason = "this is a string".
I have searched the SSIS forum for an answer to my question, and I think I have found my answer but what i have read does not come out directly and answer my question.
I am attempting to create an SSIS package that imports data from a Visual Foxpro table into a SQL Server table. From what I have read, the source and destination tables must match column for column. Is this correct? My SQL Server table has a few more columns in it. However, i consistently get "Cannot create connector. The destination component does not have any available inputs...blah".
From what i have read, it sound like the reasoning is that my source and destination tables do not match.
Is this correct, or am i barking up the wrong tree?

I add some records to two tables after createing operation completed.
Then i use dbcc page command to oversee the structures of data page in two tables. I found some interest things: The rows in two tabes take up same space:9 bytes
You can see the "9" on top of the data, for example:Slot 0, Offset 0x60, Length 9, DumpStyle BYTE or calculate from the offset array
I have a quite big SQL query which would be nice to be used using UNION betweern two Select and Where clauses. I noticed that if both Select clauses have Where part between UNION other is ignored. How can I prevent this?
I found a article in StackOverflow saying that if UNION has e.g. two Selects with Where conditions other one will not work. [URL] ....
I have installed SQL Server 2014 and I tried to use tricks mentioned in StackOverflow's article but couldn't succeeded.
Any example how to write two Selects with own Where clauses and those Selects are joined with UNION?
Hi, can anyone shed some light on this issue?SELECT Status from lupStatuswith a normal query it returns the correct recordcountSELECT Status from lupStatus GROUP BY Statusbut with a GROUP By clause or DISTINCT clause it return the recordcount= -1
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
) Once moved to SQL Server 2005 the statement would not return and showed SOS_SCHEDULER_YIELD to be the waittype when executed. This machine is SP1 and needs to be upgraded to SP2, something that is not going to happen near time.
I changed the SQL to the following, SQL Server now runs it in under a second, but now the app is not functioning correctly. Are the above and the following semantically the same?
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
1) Rows ordered using textual id rather than numeric id
Code Snippet select cast(v.id as nvarchar(2)) id from ( select 1 id union select 2 id union select 11 id ) v order by v.id
Result set is ordered as: 1, 11, 2 I expect: 1,2,11
if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
2) SQL server reject query below with next message
Server: Msg 169, Level 15, State 3, Line 16 A column has been specified more than once in the order by list. Columns in the order by list must be unique.
Code Snippet select cast(v.id as nvarchar(2)) id from ( select 1 id union select 2 id union select 11 id ) v cross join ( select 1 id union select 2 id union select 11 id ) u order by v.id ,u.id
Again, if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
It reproducible on

In both cases database collation is SQL_Latin1_General_CP1251_CS_AS
If I check quieries above on database with SQL_Latin1_General_CP1_CI_AS collation then it works fine again.
Could someone clarify - is it bug or expected behaviour?

I have a table having single column id and n number of rows and 1 want to know all combination of id's where sum or subtraction of any two id's is equal to 7.
Hello, I am writing a SP, inside the SP i have a select statement. I also have another SP, when i run it, it sends a list back with all the users that are currently online. Now in my first SP, i want to construct a select statement that returns a users data, but only for the users that are online.
This is the first SP (GetAllOnlineUsers), that produces a list with users online (just abit rewritten from the membership function total users online): SELECT u.Username FROM dbo.aspnet_Users u(NOLOCK), dbo.aspnet_Applications a(NOLOCK), dbo.aspnet_Membership m(NOLOCK) WHERE u.ApplicationId = a.ApplicationId AND LastActivityDate > @DateActive AND a.LoweredApplicationName = LOWER(@ApplicationName) AND u.UserId = m.UserId
This is my second SP, in witch i want to get the online users data: SELECT m.username, d.data1, d.data2 FROM m.userstable INNER JOIN data ON (data.username = m.username) WHERE (m.username IN (EXEC GetAllOnlineUsers)) Is it possible to exec a SP into a select statement?
It seems my sysindexes table is inaccurate on a nonclustered index. In my case the rowcount (rows and rowcnt) do not match the actual rowcount of the table. The command UPDATE STATISTICS doesn't change the rows or rowcount, adding 'FULSLCAN' won't budge rowcount either.
After I did a dbcc reindex, the number of rows matched, however, upon adding rows in the table both rows and rowcount are out of sync again.
It's a fairly straightforward table, no triggers, no computed fields, only integer, datetime, varchar and bigint columns. There's a clustered index on a bigint column and a nonclustered index on a integer column.
dbcc show_statistics show that the nonclustered index is updated and it's rows and rows sampled match the number of rows in the table (not in the sysindexes-table).
I'd like to know if I'm chasing ghosts here or if there's something very wrong here. What could be causing the counts being inaccurate? Anyone who could shed some light?
SELECT Countries.Name, Companies.ShortName, Persons.FirstName, Persons.LastName, PersonSkills.Skills FROM PersonSkills INNER JOIN....
How can I choose a certain value from PersonSkills.Skills?
for example, I would like to choose a value from PersonSkills.Skills that matches a certain product. I can do the Max/Min value but the selected value needs to match the product.
The tables that I have are: PersonSkills: id, ProductID, Skills
Product: id, ProductName
Ive been reading and playing around with this without success.
I want to select Property names or owner id from table A where there is no match between owner ID in table A and B , for example Property 3 in red. In table A only one person can be listed as owner of property. In table B many people can be listed as owner of the same property.
The way i script will return property 1 twice (as no match) because the owner ID from table A '123456' mismatch twice with owner ID from table B
'111111' and '222222'. I dont want Property 1 to be selected at all because the owner '123456' is listed as one of the owners in Table B
I have two tables in the same DB, one named “Client” one named “Case”.
-One column inside Client is “ClientID”, another is “ClientCode”.
-One column inside Case is “CaseID” and another is “ClientCode”, which corresponds to the ClientCode column in the previous table.
I need a file with output that looks like this CaseID+ClientID.
So, an example row from the “Client” table” could be ClientID = 123, ClientCode=999. An example row from the “Case table” could be CaseID=555, ClientCode=999. So, I need output of 555123 .
Scenario: 2 sets of data Set 1 (200 records): firstname, lastname, address, city, phone Set 2 (100 records): firstname, lastname, address, city, phone
I run a query using phone as criteria/condition (where xx.phone=yy.phone). I got 75 matches based on the phone numbers
However, if I deleted the phone numbers from set 2 data, used below query, the return result is only 45 matches. My question is what technique that I can use to optimize the result just based on criteria like first, last, and address.
select xx.firstname, xx.lastname, yy.Firstname, yy.Lastname, xx.address, yy.address, xx.city, yy.city, yy.phone from set2 xx, set1 yy where substring(soundex(xx.Firstname),0,3)=substring(soundex(yy.Firstname),0,3) and substring(soundex(xx.lastname),0,4)=substring(soundex(yy.Lastname),0,4) and substring(xx.address,1,7)= substring(yy.address,1,7) and xx.city=yy.city;
I have a table of employees and two sites. Most employees only do shifts at the one site but may occasionally work at the other site. What i want is the details of those who have worked at both sites.
for e.g.
Employees 1 Dave 2 Peter 3 John
Site 1 Mon John Tue Peter Wed John Thu John Fri Peter
Site 2 Mon Dave Tue Dave Wed Dave Thu Dave Fri Peter
So the answer should be 2 Peter. Hope this explains the problem. Probably very obvious but it has me stumped.
In the trading (stock market) industry there is a practice of rolling up (merging) multiple trades into a single trade in an effort to save on ticket charges. The way this is done is performing a SUM() on the quantities and calculating an average price. (Average price is the SUM(Qty * Price) / SUM(Qty).
Here is my dilema: If given a set of trades, I need to loop through them and check every combination to determine which one matches the expected rolled-up final trade. In other words,
If I know that the final trade is:
15 $10
And I have the following trades in my set:
TradeId Qty Price 1 10 $10 2 7 $20 3 5 $10
I need to check the roll-up of trades (1, 2), (1, 3), and (2, 3) and determine that it final trade was made by rolling up trades 1 and 3.
In the real situation, the number of trades that I need to check is not set to a specific number.
Any help would be appreciated. Cursors, temp tables, functions, recursive calls, .NET (I am running SQL 2005 so have access to CLR) are ALL acceptable solutions...
Here is a sample SQL code (table and data) to work with.
what is differance between conditions put in ON clause and in WHERE clause in JOINS????
see conditions that shown in brown color
select d1.SourceID, d1.PID, d1.SummaryID, d1.EffectiveDate, d1.Audit, d1.ExpirationDate, d1.Indicator from[DB1].[dbo].[Implicit] d1 inner join [DB2].[dbo].[Implicit] d2 on d1.SummaryID=d2.SummaryID AND d1.ListType = d2.ListType AND (d1.EffectiveDate <= d2.ExpirationDate or d2.ExpirationDate is null) AND (d1.ExpirationDate >= d2.EffectiveDate or d1.ExpirationDate is null) whered1.ImplicitID >= d2.ImplicitID AND (d1.SourceID<>d2.SourceID OR (d1.SourceID IS NULL AND d2.SourceID IS NOT NULL) OR (d1.SourceID IS NOT NULL AND d2.SourceID IS NULL) )
select d1.SourceID, d1.PID, d1.SummaryID, d1.EffectiveDate, d1.Audit, d1.ExpirationDate, d1.Indicator from[DB1].[dbo].[Implicit] d1 inner join [DB2].[dbo].[Implicit] d2 on d1.SummaryID=d2.SummaryID AND d1.ImplicitID = d1.ImplicitIDAND d1.ListType = d2.ListType AND (d1.EffectiveDate <= d2.ExpirationDate or d2.ExpirationDate is null) AND (d1.ExpirationDate >= d2.EffectiveDate or d1.ExpirationDate is null) whered1.ImplicitID >= d2.ImplicitID AND (d1.SourceID<>d2.SourceID OR (d1.SourceID IS NULL AND d2.SourceID IS NOT NULL) OR (d1.SourceID IS NOT NULL AND d2.SourceID IS NULL) )
another thing...
if we put AND d1.ImplicitID = d1.ImplicitID condition in second query then shall we remove d1.ImplicitID >= d2.ImplicitID from WHERE clause????
Hi everyone, I saw some queries where SQL inner join clause and the where clause is used at the same time. I knew that "on" is used instead of the "where" clause. Would anyone please exaplin me why both "where" and "on" clause is used in some sql Select queries ?
i have two tables one with id and one with storyid which match. i need to check which record is at top of table two. and then pull top four from table one where the top story from table two (storyid) is not one of the top four in table one (id). is this possible? can anyone help?
I have a need to execute a query in T-SQL on a numeric field in a SQL table. However if there is no exact match I'd likea query that will return the row that is just below my value. As an example if the table has values: 1,2,4,5,7,9, 15 and 20 for instance and I am matching with a varibale containing the value 9 then I'd like it to return that row. however if my variable has the value 19 I want the row containign 15 returned. Is this possible? Can anyone help me with such a query? Regards Clive
Find value match in SQL table Is there any application that can compare two tables and find the similarities (there is no high rate of exact match on the field values but there are similarities)?
I'm trying to correct an error that a user is getting when running SQL Server 7.0 SP3, Desktop edition/ Windows NT 4.0 SP6. The error says that C:WINNTSYSTEM32odbcint.dll and C:WINNTSYSTEM32odbccp32.dll are different versions. I tried to install MDAC 2.5 sp1 to correct this problem but this message continues throughout the install. This is causing sqlagent service to hang. Any ideas of how to reinstall ODBC components without reinstalling the OS?
I asked this question in the mysql forums, but I am also interested in any info regarding MSSQL. I've seen databases with search systems with the functionality I seek below. I just have no idea how they are doing it. Thank you.
We have an mysql inventory database. We want to be able to put in 4984.600 and choose "match any portion" and it finds 4984600 which is in our database.
Does Mysql have a "match any portion" search function? In this case LIKE didn't work which we tried already.
Any ideas? or are we stuck with using MSSQL. We know this will work with MSSQL.
Thank you very much. This is a huge problem for us.
I asked this question about mysql on another forum, but I would also like to know about MSSQL. I may need to switch to this platform if Mysql doesn't work. Here's my problem:
Instead of "match", I am looking for a "match any portion" way to do searches with mysql.
