I need to do a conditional insert, and I am afraid that if I do it in 2 steps it will create bugs...I have a table called customers and a table called lockscustomers has 3 fields CustomerID, FirstName, and LastNamelocks has fields LockID, CustomerID, UserID, SessionID, and TimeStampI need to check if there are any records in Locks for a CustomerID and if there are none, I need to insert One.This is going to tell my application that this Customer record is locked so no one else can edit it, until the Lock record is deleted.I just don't want to make 2 trips, One to check if the Lock exists, then One to insert the Lock, since this could allow 2 locks to be created if the timing is correct.Any ideas or comments?

Now how can I reverse this to insert all the values back to tbl FULLSOURCE from maybe an updated SSOTARGET Tbl. FULLSOURCE looks like this:

I need to do a conditional because sometimes the select that returns data contains no records.
Hello all. I am inserting data into a table from a linked server (.XLS file). One of the columns deals with dates. In the .XLS file some ofthe dates are invalid (either wrong format or wrond data). What i am looking for is how to insert only the rows where the dates are correct. My basic structure is:

I am new to MSSQL and am trying to write a complicated SQL statement that I'm having trouble with. Any help that anyone can offer is much appreciated!
Here is the problem I am tackling:
I have a list of about 5,000 members of our organization stored in the MemberList MSSQL table. I have a separate MSSQL table (CityList) that has approximately 500,000 resident of a city.
I am trying to find matches between MemberList and CityList for the purposes of figuring out which of our members are registered voters.
The tricky part of this problem, is that there is no unique ID (such as a social security number) that is present in each list. Accordingly, I have decided to created several types of matches:
1. NameDOBMatch: Where the FirstName, LastName & DOB fields in MemberList table match the same fields in CityList table.
2. NameAddressMatch: Where the LastName, FirstName & Address fields in the MemberList table match the same fields in the CityList table.
3. DoubleMatch: A combination of the first two matches (i.e. where the LastName, FirstName, DOB, & Address fields in the MemberList table match the same fields in the CityList table).
My goal is to "loop" through the MemberList and CityList tables and to add a new row to a third MSSQL table (MemberMatch) each time one of the aforementioned matches is found. The MemberMatch table has the following fields: 1. MatchID (key) 2. MemberID (Unique ID of member from MemberList table) 3. ResidentID (Unqiue ID of matching member from CityList table). 4. MatchType (value of NameDOBMatch, NameAddressMatch or DoubleMatch, depending on match type).
If anyone could help me create an SQL statement that would accomplish that, I would very much appreciate it!
Is there any way to create a "Conditional Insert Trigger" My Scenario is this; When a user adds an email address to the database, I want to look to see if the email address is like '%@acme-holdings%' and if it is then to change the value to 'Not allowed', otherwise to leave it alone and go ahead with inserting the original email address

I've got a case where I am bringing older data into a brand new DB. Unfortunately, there are several versions of the old DB and I won't know ahead of time which one I will be running against. The data's basicaly the same, the table names are the same, but the column schema is NOT. Basiclly, I want to use a conditional on the Insert.
Code Block
CREATE TABLE TestTable (Col1 int NULL, Col2 varchar(50) NULL) GO
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_CATALOG= 'TestDB' AND TABLE_NAME ='TestTable' AND COLUMN_NAME= 'Fred')
This results in an "Unknown column" error. What am I missing here and how can I accomplish it. I know that I COULD build a SQL string and Exec it, but that is such a PITA and not very elegant.
I have several places where I need to get the id (primary key) of a resource, inserting a row if the resource does not exist (i.e. an artificial key to be used as an FK for another table). I should probably change this varchar key lookup to use a hash index, but that is beside the point.
So the table is essentially like: CREATE TABLE MyLookup(id int identity primary key nonclustered, mykey varchar(256)); CREATE CLUSTERED INDEX mylookup_cidx_mykey ON MyLookup(mykey);
I see two main approaches for how I can do my get-id-with-insert-if-needed.
(Approach 1) DECLARE @id INT; SELECT @id = id FROM MyLookup WHERE mykey = 'some key value'; IF (@id is null) BEGIN
INSERT MyLookup ('some key value'); SET @id = SCOPE_IDENTITY(); END
(Approach 2) DECLARE @id INT; INSERT MyLookup SELECT 'some key value' WHERE NOT EXISTS (SELECT id FROM MyLookup WHERE mykey = 'some key value'); IF (@@ROWCOUNT = 0)
SELECT @id = id FROM MyLookup WHERE mykey = 'some key value'; ELSE
SET @id = SCOPE_IDENTITY();
From some quick tests in profiler, approach 2 seems to be a bit faster and have lower resource utilization. But I'm not sure if it maybe takes some more aggressive locks even in the unnecessary case where the mykey row value of 'some key value' already exists. Approach 2 also looks cleaner to me, but I don't mind a bit of extra code if it gives me better scalability through less lock contention.
Any tip on what is considered the best practice for a conditional insert like this, or a tip on how to get detailed lock info for a query? The lock info for profiler was all greek to me, it just had a hex value with each lock acquired/released, so I have no idea what it was telling me. Is my only solution to just run exhaustive tests and look at the perf numbers from the black box?
MID, IIN and NUM_EVENTS are composite keys. and only NUM_EVENTS get incremented. All records start with NUM_EVENTS = 1.How can I create a query that only displays those records that only NUM_EVENTS = 1 meaning their still on the first stage of processing?

--- expected results please execute below block ( per each segment 2 records will insert if there is segment ='VEC_BAL' or 'PPC_BAL' ). If there is no Vec_Bal or PPC BAL then no additional inserts, if there is only VEC_BAL no PPC_BAL then only 2 records insert SELECT L.Segment , l.email, l.Addr1 , l.City ,l.ST, l.code, s.Fname , s.LName into #expctresults1 FROM #LIST L JOIN #Subject S ON l.Segment =s.Segment union

Hi,I'm trying to do calculations in a SQL statement, but depending on onevariable (a.type in example) I'll need to pull another variable fromseperate tables.Here is my code thus far:select a.DeptCode DeptCode,a.Type Type,(a.ExpenseUnit / (select volume from TargetData b where b.type =a.type)) ExpenseFromcalc1 aThe problem... a.Type can be FYTD, Budget, or Target... and dependingon which one it is, I need to make b either FYTDData, TargetData, orBudgetData. I'm thinking a case statement might do the trick, but Ican't find any syntax on how to use Case in an MS SQL statement. EvenIf statements will work (if that's possible), though case would beless messy.Any suggestions would be much appriciative. Thanks...Alex.
Hello, I've been researching this for some time. Does anyone know if you can conditionally jump to a report? Something like this:
=iif(Fields!TEST.Value = "?????" And Fields!TEST2.Value > 0, TestDetailReport, "") I've tried this based on the text color also but keep getting errors like this:
The expression for the textbox €˜TESTBOX€™ contains an error: [BC30451] Name 'TestDetailReport' is not declared.
I am using conditional split Checking to see if a record exists and if so update else insert. But this cause database dead lock any one has suggestion?
Hi everybody !!! I have a problem with database SQL server 2000, and I need anyone help me.
I have PC machine with hardware configuration following:
+ RAM : 512M
+ CPU : 2.4 GHz (intel Pentium 4)
+ System : Microsoft Windows Server 2003 Enterprice Edition , Service Pack 1
(this is call Machine1 )
and other Server machine with hardware configuration the following :
+ RAM : 2G
+ CPU : 3.6 GHz( intel Xeon)
+System : Microsoft Windows Server 2003 Enterprice Edition , Service Pack 2
(use RAID 5)
(this is call Machine2 )
.And SQL Server 2000 is installed in these machine.
I created one table and one script to insert several records into this table. and script for inserting:
declare @count int , @max int
set @count =1
set @max = 5000
WHILE (@count < @max or @count = @max)
BEGIN
insert into TBAT_STOCKEOD(TRDT,SEQNO,COMPID,TRANSTYPE) values('20071219',cast(@count as varchar(5)),'13215','1')
set @count = @count +1
END
I execute this script on Machine1 and Machine2 :
+ Machine1 : spent 3 seconds.
+ Machine2 : spent 30 seconds. I don't understand why Machine2 is slower than Machine1 ( while configuration of Machine2 is better than Machine1's ). I don't know what happen.
I checked resource usages in perfmon when SQL server execute script and result following :
Machine1:
Proccessor used 100%
whereas,Machine2 used physical Disk 100%
Is there the way to configurate SQL server to improve speed writting of hard disk?

Hi everybody,I just wrote my first two triggers and from the minimal amount of testing Ihave done, they work! However, I was hoping I could get some feedback fromthose of you more experienced in writing triggers.Here is the first one:CREATE TRIGGER DecreInters ON InteractionFOR DELETEASdeclare @stu INTdeclare @num INTselect @stu = Student_FK from deletedselect @num = (select Inters from Student where Student_Key = @stu)UPDATE StudentSET Inters = @num - 1FROM StudentWHERE Student.Student_Key = @stuHere is the second one:CREATE TRIGGER IncreIntersON InteractionAFTER INSERTASdeclare @stu INTdeclare @num INTdeclare @last_rec INTselect @last_rec = @@IDENTITYselect @stu = (select Student_FK from Interaction where Interaction_ID =@last_rec)select @num = (select Inters from Student where Student_Key = @stu)UPDATE StudentSET Inters = @num + 1FROM StudentWHERE Student.Student_Key = @stuAre there any shortcuts I could use or things I could do to make thesetriggers more efficient. Please give me some feedback and let me know ofany problems that might possibly be caused due to my doing this improperly.Thanks ahead,Corey
Hi, How can i store the record insert/update timestamp in a SQL server 2000 db programacally. ? what are the date/time functions in ASP.NET 2.0 ? I know that this can be done by setting the default valut to getdate() function in SQL, but any other way on ASP page or code-behind page ???
I have current current sql server 2000 database containing some columns in big5. To display these cols correctly, my asp.net nust have directive with CodePage="1252" ContentType="text/html;charset=BIG5". I can not update, or insert big5 character into these columns via .aspx page. I'm using .net framework 2.0. Please help me, thanks a lot for any help.
Im having a lot of trouble inserting a small time value into a table cell. I gave the cell column the data type 'DateTime', i found i couldnt manually insert a time only value such as '12:30 PM' into a column with 'SmallDateTime'. Something about a "SmallDateTime Overflow Error". However if i enter a similar time value into a table column with the data type 'DateTime' it will happily accept it and leave it as entered.
The real problem seems to be when i try to send a time value to that column with my ASP.NET application. Because it inserts the time value and todays date. So that if i send:
12:30 PM
It will be stored as:
15/11/2003 12:30:00 PM
I only want to store the short time, not the date especially not the date that row was created on because thats useless for the purposes of what my application is trying to achieve and just creates problems down the track when selecting rows.

I'm running a resource-intensive stored procedure, which reads a filewith about 50,000 lines with a BULK INSERT into a temp table, thengoes through it and inserts a record for each line into another table.While this procedure is running, SQL server stops accepting any otherrequests coming from the website.Question:Is there a way to make SQL server "listen", or emulate an "interrupt"to other requests while in the middle of a long intensive process?I really appreciate your replies.Thank you,Oleg.

Is there a way in order to execute a subscribed report based on a certain criteria?
For example, let's say send a report to users when data exist on the report else if no data is returned by the query executed by the report then it will not send the report to users.
My current situation here is that users tend to say that this should not happen, since no pertinent information is contained in the report, why would they receive email with blank data in it.
I have the following code in the color property of a textbox. However, when I run my report all of the values in this column display in green regardless of their value.
I need to add a join in my select query depending upon a variable @LoggedUser. the Join is to be there if @loggedUser is 1 else i do not need it. Currently I am using two different queries one with join and one without it under If (@LoggedUser check).
the join is like - JOIN (SELECT CAST(CONVERT(VARCHAR(8),Analyst_Effective_date , 1) AS DATETIME) Analyst_Effective_date FROM Users us (NOLOCK) JOIN Primary_Analysts (NOLOCK) ON User_Count_Id = Analyst_Id_fk WHERE User_Count_Id in ((SELECT VALUE FROM dbo.fParseString(@Analyst, ',')) )) Ana ON dep.Departure_Code = Ana.Primary_Analyst_Departure_Code_fk )
Any way that the join can be added conditionally in the query so i do not have to write the whole code again for one join.
I have two tables tabA (cola1, cola2, cola3) and tabB(colb1, colb2, colb3, colb4) which I need to join on all 3 columns of table A.
Of the 3 columns in tabA, few can be NULL, in that case I want to check the joining condition for the rest of the columns, so its conditional joining. Let me rephrase what I am trying to acheive - I need to check if the columns in joining condition is NULL in my 1st table (tabA), If so I need to check the joining condition for the rest of the two columns, if 2nd column is again NULL, I need to check the joining condition on the third column.
What I am trying to do is as below. Its working, but is very slow when one of the tables is huge. Can I optimize it or rewrite in a better way ?
--- First Create two tables Create table tabA (cola1 nvarchar(100), cola2 nvarchar(100), cola3 nvarchar(100)) Insert into tabA values (NULL,'A1','A2') Select * from tabA create table tabB
