I am having in writing a simple select command........
here's My Problem
I am using the ASP SQLDataSources in VS2005.... and my need is that i need to show Products details in a Gridview......
Actually through QueryString a StoreID is being fetched..... and the Products under those StoreID are shown..... if there is nothing in query string then it should show all the results... ........ It means that my querystring should be something like this
select * from tblProducts where StoreID = <xyz>
and <xyz> should be some thing that could show all the rows in that table ........ i mean that it should show all the possible results that can be shown through...
This simple query is designed to show all members with the same first name as other members. The result I got shows duplicates of existing members an inconsistent number of times even though I specified not to show duplicates with WHERE m1.MemberID <> m2.MemberID

Any help in explaining where I have gone wrong here would be greatly appreciated.
I have a query as follow: SELECT @resRate = (SELECT resRate FROM ProjectAssign WHERE proNo = (SELECT projNo FROM Timer_Cust WHERE refNum = @actProjNo AND username= (SELECT username FROM Timer_Emp WHERE refNum = @actEmployee) ) ) the definition of table Timer_cust contains refNum(int), projNo(varchar) and projName(varchar).Timer_cust table doesn't contain column username. So this query shoud generate a runtime error. however it works fine without error.But if I run SELECT projNo FROM Timer_Cust WHERE refNum = @actProjNo AND username= (SELECT username FROM Timer_Emp WHERE refNum = @actEmployee)A runtime error message appears.Why?
hi there , i'm using sql server 2005 express and i have some problems with the two of my tables :), iwant to query both of my tables but the table entries are not in an equal count of rows for example:
incoming(table) outgoing(table)
money date corp money date corp 15 1,1,2006 ar 17 1,1,2006 ar 25 1,2,2007 ar 21 2,2,2007 es 35 2,2,2007 es 6 3,3,2007 ar
in this example the first table has more rows but the opposite is possible in my tables because this is an (account extract) query and here's my problem: first i used the "select incoming.money as m1,incoming date as d1,incoming.corp as c1,outgoing.money as m2,outgoing.date as d2,outgoing.corp as c2 from incoming left outer join outgoing on incoming.corp=outgoing.corp where incoming.corp='ar'(or don't use the where eliminating)" any way i couldn't get the correct results, then i used the (union all) select , the result was ok but the results form is not what i want here's the form i want and is it possible to query to tables to get this? in this query i just wanted the elements with the corporation named 'ar' for example:
m1 m2 d1 d2 c1 c2
15 17 1,1,2006 1,1,2006 ar ar 25 null(or (0)) 1,2,2007 6 null(or (0)) 3,3,2007
is it possible to achieve this form(and may be any of the tables may have more rows than the other, it's not exact) , i am in a very difficult position :) and now i need your help , thanks anybody to think of helping me

First off, let me get my disclaimer out of the way - I'm a relative newbie at this SQL lark, so please ignore the kludgy-ness of this code etc. Thanks ;-)

When I run this query in Query Analyser, it seems to work fine. IE. I get a table returned with the correct values. However, when I try and get this data into ASP via the old objRS.open "EXECUTE stored procedure <value>" command, no data is returned...
I'm not sure if this is an ASP problem, or a SQL problem... So, I altered the query slightly, and instead of a temporary table, I used a static one in the database, and it still didn't work - even though when I open the table in Enterprise manager the content is there...
Also, if I run the query via an ASP objCommand.execute "procedure <value> " and then use objRS.open "SELECT * from table" then it pulls the data in properly then...
If I was dealing with millions of recordsets in my original table, then I can understand that maybe the ASP isn't waiting long enough for SQL to return its final table. But I'm currently only dealing with about 50... I'd rather use the temporary table route rather than static incase of multiple hits at the procedure at the same time...
Any ideas? Please go easy - I refer you back to my disclaimer ;-)

Hi all,Using SQL Server 2000, SP4.I have a table of street names (Rua) whose ids (cod_rua) are foreignkeys into a consumer table (Consumidor). It turns out that the "Rua"table has many unused records which I'd like to wipe out. For instance,there are some 2800 unused records in the "Rua" table, and only some200 records actually being used by the "Consumidor" table (which,itself, has some 5000 records).Attempting to find the unused records, I issued the following query:a)SELECT COD_RUA FROM RUAWHERE COD_RUA NOT IN (SELECT COD_RUA FROM CONSUMIDOR)To my surprise, the query came out empty. But the following queryshowed the 200 or so records which *are* being used:b)SELECT COD_RUA FROM RUAWHERE COD_RUA IN (SELECT COD_RUA FROM CONSUMIDOR)I've found two solutions for the query to list the records *notexisting* in the Consumidor table:c)SELECT COD_RUA FROM RUAWHERE COD_RUA NOT IN (SELECT COD_RUA FROM CONSUMIDORWHERE COD_RUA IS NOT NULL)d)SELECT COD_RUA FROM RUAWHERE COD_RUA NOT IN (SELECT COD_RUA FROM RUAWHERE COD_RUA IN (SELECT COD_RUA FROM CONSUMIDOR))I know that there are many other possible solutions to the query(including left joins), but what I don't understand is why the query a)failed.Can some of you, oh mighty gurus, enlighten me?For the record, here's how both tables are (partially) declared:CREATE TABLE Rua (Cod_Rua int NOT NULL ,Rua varchar (35) NULL ,-- ...-- other unrelated fields-- ...CONSTRAINT Pk_CodRuaPRIMARY KEY (Cod_Rua))CREATE TABLE Consumidor (Cod_Consumidor int NOT NULL ,Cod_Rua int NULL ,-- ...-- other unrelated fields-- ...CONSTRAINT Pk_CodConsumidorPRIMARY KEY(Cod_Consumidor) ,CONSTRAINT Fk_CodRua_ConsumidorFOREIGN KEY (Cod_Rua)REFERENCES Rua (Cod_Rua))Regards,Branco Medeiros
Hi everibody,it's the first time i post on this newsgroup. I'm Stefano from Milano,italy.I'm a beginners with Sql2000.

Last week we've made some modifications to our 20 GB database(with 2 huge tables (around 30 million rows)): 1. we've created 8 filegroups on 8 physical disks with RAID 1+0. In each of them we have one big table and others small tables unrelated with the big table. We've also created a filegroup for the nonclustered indexes from those big tables. 2. The Server is running SQL Server 2000 with SP3a 3. We've reindexed the database, updated statistics on all tables Now, we have a SP that on the old configuration took about 20 min to complete. But now, on our new configuration with the modifications listed above it's taking about 3 HOURS. This is the SP's body: is calling a function: create proc X as begin Select dbo.myfunc(mytable.field) from mytable end
The function used in select statement is querying those 2 huge tables.
If the select statement is runned for only one record it's done instantly, but for 20000 recs it is taking almost 3 hours. I must specify that also the function is running instantly, but in that select statement something is happening and we don't know what!!!
If you have any ideeas on what to do or what to check Thanks a lot Dan
I am seeming strange results with a query. I have two tables, lets call them Table1 and Table2. Table1 has an ID field, Table2 does not have an ID field. To be sure I wasn't blind, the query
'SELECT ID FROM Table2'
returns: Invalid column name 'ID'. OK. Now when I run the query
'SELECT * FROM Table1 WHERE ID IN (SELECT ID FROM Table2)'
it returns all the records from Table1.
What gives? Is this a bug, or am I missing something?
Jezemine, No, the number of reads is approximately the same. I can also confirm the disk read speed is the same on the test vs. production server. Update stats is run regularly on the production server - as I test, I ran sp_updatestats and then immediately ran the query a few times but it didn't affect the duration. Apart from the durations in the profiler traces, I can't see any differences. Clearly, something is causing the increased duration on the prod server but I don't know where to look to find it. It's definitely within SQL Server 2000.
I have been trying to get this code work, but I could not. Every thing seems going well. However, The result of running the sql query is strange. It shows the field names twice. Eg:) if you have a table called "newtable" that has two fields[Custnumber, Custname], you will get somthing like this [Custnumber, Custname Custnumber, Custname]. I have tried many times, but I couldn't fix it.

We have SQL server 7 installed. And we experiencing the performance problem. When I tried to solve this problem I have found the interesting thing: We have the table S_EVT_ACT with the non clustered index S_EVT_ACT_F4 created on [OWNER_PER_ID], [APPT_REPT_FLG] fields and another clustered one S_EVT_ACT_M4 created on [ROW_STATUS], [OWNER_PER_ID] fields I use the next select statement and before run this statement I declare the variable @P1 - @P5 and set the values to them:
declare @P1 as char(1) declare @P2 as char(1) declare @P3 as char(1) declare @P4 as varchar(10) declare @P5 as char(1)
set @P1 = 'Y' set @P2 = 'Y' set @P3 = 'N' set @P4 = '1-K56' set @P5 = 'Y'
SELECT .. ... ... FROM dbo.S_EVT_ACT T1 --(index = S_EVT_ACT_F4) LEFT OUTER JOIN dbo.S_CONTACT T2 ON T1.TARGET_PER_ID = T2.ROW_ID LEFT OUTER JOIN dbo.S_OPTY T3 ON T1.OPTY_ID = T3.ROW_ID LEFT OUTER JOIN dbo.S_ORG_EXT T4 ON T1.TARGET_OU_ID = T4.ROW_ID LEFT OUTER JOIN dbo.S_EVT_ACT_X T5 ON T1.ROW_ID = T5.PAR_ROW_ID WHERE ((T1.ALARM_FLAG = @P1 OR T1.APPT_REPT_REPL_CD IS NOT NULL) AND (T1.APPT_REPT_FLG = @P2 AND (T1.CAL_DISP_FLG = @P3 OR T1.CAL_DISP_FLG IS NULL)) AND (T1.OWNER_PER_ID = @P4) AND (T1.TEMPLATE_FLG != @P5 OR T1.TEMPLATE_FLG IS NULL)) ORDER BY T1.CREATED
In this case Query Analyzer uses S_EVT_ACT_M4 index and the performance is bad!
But when I try to run the same statement and use hard code 'Y' instead of the variable @P2 the Query Analyzer uses the S_EVT_ACT_F4 index and performance is PERFECT.
Question: What the difference between using variable @P2 and hard code 'Y' in the select statement and how to configure SQL server to use the right index in the situation when I can't change the Select statement and use the hard coding?
Any Idea will be very Appreciated.

I am trying to make a single display page for an author's books.the books page only displays books of a type "type" (novels, non-fiction, etc)I would like to make it so that it can also show all books if "type" isn't selected. I THOUGHT the string would look like this: <asp:SqlDataSource ID="SqlDSBooks" runat="server" ConnectionString="<%$ ConnectionStrings:csK2Reader %>" SelectCommand="SELECT * FROM [Books] ( If @Type <> "" then WHERE ([Type] = @Type)) ORDER BY [SortDate] DESC"> But it doesn't seem to want to work. I get a "server tag is not well formed" error.
I have a table called "member" that has two fields (amongst others) called "firstname" and "city"I want to return a list that sorts people who live in the same city, but does not return people who do not have a city in common.For example if this is my data:Karen - ParisMike - RomeTim - Dallas
Jim - ParisChris - DallasJohn - ManhattanSarah - OrlandoDavid - DallasThe query would return this:Dallas - ChrisDallas - DavidDallas - TimParis - JimParis - KarenI have this SQL so far: Select city, firstname From member Order By city, firstnamebut it includes all the cities including those that only have 1 resident.Can someone tell me how to do this?Thanks a lot,Chris

Hi All Can anyone tell me what this simple SQL query would be: Find all the words "black", "dvd" and "player" from any of the fields "Product", "Brand" or "Description".
I am trying to select players from a database based on the userid not having any user's name in it with an order by ASC. I basically want all the players that haven't been taken. Here is what I came up with and it gives me empty.
strSQLA="SELECT UserID, playerName from Allplayers WHERE UserID = '' ORDER BY playername ASC"
I hope it's considered appropriate to post a SQL query question here; it's not I'll gladly post this question elsewhere. That having been said, I've run into a simple but quite tricky SQL query and was wondering if the community might be able to help. Here's what's going on: I have a "Documents" table. Let's call it DI have a "Benefits" table. Let's call it B.There is a many-to-many relationship between D and B so I have a third table to store the relationships. Let's call that table BD. When I create a document it creates a row in D. Let's call that D1, D2...DN. When I create a benefit it creates a row in B. Let's call that B1, B2...BN When I associate a document to a paritcular benefit, let's say that if D1 and B2 are associated, that I created row B2-D1 in my BD table. Now here's what my challenge is. Suppose I have these entries in my tables: D: D1, D2, D3B: B1, B2, B3 Table BD:B1-D1B2-D1B2-D2 When the user goes to add documents to benefit B1, I want to show the user only documents that are not yet added to B1. In this case, I want to show the user D2 and D3 but not D1 since that one's already added. How do I write a SQL query to do this? Here's what I've been using, but it shows too many results (e.g. included D1, D2, D3) SELECT D.*, BD.*FROM Documents AS d LEFT JOIN rel_BenefitsDocuments AS bd ON d.doc_id = bd.doc_idWHERE (benefit_id <> @benefit_id OR benefit_id IS NULL) Any thoughts?
I want to write a sql query for an asp page which will display only unique rows from the specified column along with the number of count for each unique row.
Example:
Table that I want to query
Last Name || First Name Gates || Bill Boyce || Mike Gates || Bill Gates || Phil
Results I want:
Last Name || First Name || Count Gates || Bill || 2 Boyce || Mike || 1 Gates || Phil || 1
I am new to SQL and this question may be most easiest to many of you. Here is what I need.
I have two identical tables (exactly the same in structure) having a compound primary key with a combination of 3 columns. Can someone give me the most efficient query that fetches all the rows from table1 that are not in table2.
from sales_contact sc , invoice i , invoice_line_item il , sales_region_special_section srss , sales_region sr , issue_date idd
where sc.sales_contact_id = i.sales_contact and i.invoice_id = il.invoice and srss.sales_region = sr.sales_region_id and il.issue_date = idd.issue_date_id and srss.invoice_line_item = il.invoice_line_item_id
order by sc.sales_contact_id

heres some of the result set I want only the records with the greatest id for each unique sales contact...

This should be easy, I'm just having a brainfart at the moment, can't remember how to do this:
Say I have a bunch of records in a table, with an ID field as Key. I want to return the count of times each ID shows up, so for the following example data:
This should be obvious but for some reason I can't see it.
When this is done I'm going to join in another table to get a name based on the ID with the highest count. I believe it's faster to do a TOP 1 here rather than after the join, but I want to verify that while I'm at it also.
I am a complete newbie to SQL. I have a simple query to make in SQL, but I'm not being able to construct the statement properly. I've already tried googling this info, but with little luck. If someone could help me here, I'd be very thankful.
The problem:
I have a table with a list of questions. All questions have a serial number. The query has to return whether a particular question is the last one in the table or not (according to serial no.)
Logically, this is the query -
Code:
select islast = 0 if count(*) from question where serialno > $serial != 0 else select islast = 1;
The '$serial' part will get replaced dynamically before query execution through another program.
Any idea how to code this in valid SQL? I would like to make it a simple statement and not a stored procedure. Thanks.
Hey.. hope someone can help, i desperatly need some assistance. I have a few query issues but first things first.. one is that i have a table of messages and users having an online conversation, so fields are msg id, subject, topic, message, user, reply to and time it was sent. Im trying to do a query that will tell me which user sent the most messages, ive tried using count and stuff like that but not really getting anywhere. It will basically have to count each time a user has spoken and then give me the name of the user that has sent the most messages, ive been playing around with stuff like SELECT Count(*) AS Expr1 FROM Table1 WHERE User='andro8472' OR User='bumies';
That will count the times those users have spoken but cant get further
any help would be greatly appreciated really stuck at the mo..
