I'm getting syntax errors when I click check syntax (near keywords insert from and end).
one other note: this CASE END is nested inside a BEGIN END loop, is this the problem? Is the 'End" of the 'Case' closing the 'End' of the 'Begin'?
I am new to msSQL and ASP, I need some help writing an SQL statement that will first check to see if a combination or record exists, if none found thant it will add it. I am working a section of a site that adds favorites to the database. Each user can have more that one favorite hence it has to check for that unique combination of the fields, UserID and FavID
My Code: Dim objConnection, objRecordset, strSQL Dim strFavID, strUserID strFavID = request.Form("favid") strUserID = request.Form("userid")
Set objConnection = Server.CreateObject("ADODB.Connection") Set objRecordset = Server.CreateObject("ADODB.Recordset") objConnection.Open Application("ConnectionString")
strSQL = "INSERT INTO FAV (UserID,FavID) (SELECT DISTINCT " & strUserID & " AS UserID " & _ strFavID & " AS FavID" & " FROM FAV)" & _ " WHERE " & strUserID & " & " & strFavID & " NOT IN (SELECT UserID, FavID FROM FAV)" response.Write(strSQL) 'response.End()
If strFavID <> "" Then On Error Resume Next objConnection.Execute(strSQL)
objConnection.Close Set objConnection = Nothing End If
This code is giving me a syntax error, how do I write the correct statement. I am using MS Access 2k
I had implemented as in the link to insert or update http://blogs.conchango.com/jamiethomson/archive/2006/09/12/SSIS_3A00_-Checking-if-a-row-exists-and-if-it-does_2C00_-has-it-changed.aspx
What i want to know is... how can i assume there are no duplicate records. I used Distinct keyword and queried it showed me all are distint but some where i find some duplicates just don't know why i am having when i look at the data both are exactly same...
I am checking to see if the source record is available in the target table using a lookup transformation and if not found i have to insert this record. I have connected the error flow of the lookup transformation to the target. I am acheiving expected results, but is this the best practise? I have not connected to the green arrow to any task.
I've decided to post this as a sticky given the frequency this question is asked.
For those of you wishing to build a package that determines if a source row exists in the destination and if so update it else insert it, this link is for you.

Hello,I have a TextBox and an Insert Button, it works like this: protected void Button1_Click(object sender, EventArgs e) { String strConn=SqlDataSource1.ConnectionString; SqlCommand cmd = new SqlCommand("INSERT INTO My_Table_1 (Column_1) VALUES ("+TextBox1.Text+")", new SqlConnection(strConn)); cmd.Connection.Open(); cmd.ExecuteNonQuery(); cmd.Connection.Close(); } But, what code i must write for checking, if the value i am trying to insert already exists ??I mean something like this:if (TextBox1.Text does not Exists on any Record in My_Table_1) then Insert itelse Show Message : "Already exists a record with this value"Thank you SO MUCH, guys,Carlos.
Hello,I created the following SQL script to check if a record exists:IF (EXISTS (SELECT LevelName FROM dbo.by27_Levels WHERE LOWER(@LevelName) = LOWER(LevelName))) Return (1)ELSE Return (0)And I also found in a web page another solution:IF EXISTS(SELECT 1 FROM TABLENAME WHERE LevelName=@LevelName) SELECT 1ELSE SELECT 0- Which approach should I use?- Why "SELECT 1 FROM"?- And when should I use SELECT or RETURN?All I need is to know if the record exists ... nothing else.I will use this procedure on an ASP.NET 2.0 / C# web site.I am not sure if this important but anyway ...Thank You,Miguel
Hi, I was wondering if someone can help. In vb.net what is the best way to check if a record exists if you are using an sql data reader? For my application I need to display a button control (make it visible on the page) if a record is available after executing my sql select statement. cheers Mark :)
I can't seem to get this work. I'm using SQL2005 I want to check if a record exists before entering it. I just can't figure out how to check it before hand. Thanks in advance.

I've got two tables, one containing a list of company names(approx 10,000 records), the other containing a list of company employees (approx 30,000 records) joined by the CompanyID column.
I have a third table (approx 700 records) containing new employees to be added to the employee table. Each record in this table has the employees details plus the name of their company.
I want to write a query that will check each row in the third table to see if a) the employee exists in the Employees table b) the company exists in the Companies table and c) the employee is listed under the correct company
The query should also handle any combination of the above. So if the company doesn't exist but the employee does, create the company on the companies table and update the appropriate record on the employees table with the new CompanyID etc. etc.
Oh, forgot to mention. The company names in the third table won't be exactly the same as the ones in the Company table so will need to use CharIndex.
I'm trying to check which price grids are in use using the price grid_id, and seeing whether this grid_id exists in another query that checks all active contracts. If the grid_id is present (active) I want to return 'Yes', if not I want it to return 'No'.
There are 385 price grids, but my query is only returning the 315 that are active, and ignoring any that are not used. My code is below, how I can see all the records whether Yes or No:
Select distinct pg.grid_id [Price Grid], pg.grid_name [Grid Name], case when exists (Select c.grid_id from customers c inner join deltickhdr dh on dh.acct = c.custnum and dh.stage <5 where c.type = 'C' and dh.dticket is not null) then 'Yes' else 'No' end [Active]
From gridhdr pg inner join customers c on c.grid_id = pg.grid_id
I have two tables with the same field layout, and they both have the same field as the Primary Key. They just contain different data. I would like to know if a record exists in one, or both, tables.
The tables are InvTemp1 and SalesTemp1. The key for both is stock_number.
Here is the command so far:
SELECT COUNT(*)
FROM InvTemp1 INNER JOIN SalesTemp1 ON InvTemp1.Stock_number = SalesTemp1.Stock_number
I have a client who needs to copy an existing sale. The problem isthe Sale is made up of three tables: Sale, SaleEquipment, SaleParts.Each sale can have multiple pieces of equipment with correspondingparts, or parts without equipment. My problem in copying is when I goto copy the parts, how do I get the NEW sale equipment ids updatedcorrectly on their corresponding parts?I can provide more information if necessary.Thank you!!Maria
Hi I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Hey gang, I've got a query and I'm really not sure how to get what I need. I've got a unix datasource that I've setup a linked server for on my SQL database so I'm using Select * From OpenQuery(DataSource, 'Query') I am able to select all of the records from the first two tables that I need. The problem I'm having is the last step. I need a field in the select statement that is going to be a simple yes or no based off of if a customer number is present in a different table. The table that I need to look into can have up to 99 instances of the customer number. It's a "Note" table that stores a string, the customer number and the sequence number of the note. Obviously I don't want to do a straight join and query because I don't want to get 99 duplicates records in the query I'm already pulling. Here's my current Query this works fine: Select *From OpenQuery(UnixData, 'Select CPAREC.CustomerNo, CPBASC_All.CustorCompName, CPAREC.DateAdded, CPAREC.Terms, CPAREC.CreditLimit, CPAREC.PowerNum From CPAREC Inner Join CPBASC_All on CPAREC.CustomerNo = CPBASC_All.CustomerNo Where DateAdded >= #12/01/07# and DateAdded <= #12/31/07#') What I need to add is one more column to the results of this query that will let me know if the Customer number is found in a "Notes" table. This table has 3 fields CustomerNo, SequenceNo, Note. I don't want to join and select on customer number as the customer number maybe repeated as much as 99 times in the Notes table. I just need to know if a single instance of the customer number was found in that table so I can set a column in my select statement as NotesExist (Yes or No) Any advice would be greatly appreciated.
SELECT 'abc' + '-' + CAST(SeqNo AS VARCHAR) + '-' + CAST(Payment AS VARCHAR) FROM abc WHERE SeqNo = 1 UNION SELECT 'def' + '-' + CAST(SeqNo AS VARCHAR) + '-' + CAST(Payment AS VARCHAR) FROM def WHERE SeqNo = 1 abc-1-200.00 abc-1-500.00
As you can see since 1 doesn't exists in table 'def' nothing is returned as expected. However, if a row isn't returned I want to be able to enter my own row such as

Basically, I need to insert the wbs2 and wbs3 where it does not exist in each wbs1.
What I have now will find the values that need to be inserted for a particular project but I don't know how to go through each project and perform the insert:
Select * from PR_template Where Not Exists (Select Wbs1, Wbs2, Wbs3 from PR where PR.WBS2 = PR_Template.WBS2 And PR.WBS3 = PR_Template.Wbs3 and pr.wbs1 = '123-456') Order by wbs2, wbs3 asc
it's me again :) I've got a - what I think - simple question. There is table A with Col1,Col2,Col3 and Table B with Col1,Col2,Col3
I want all rows from B in A. If a row already exist in A, then update all columns, else just insert the row. Can someone please help me with a small syntax. Thank you!
I am using the following code to insert records into a destination tablethat has a three column primary key i.e. (PupilID, TermID &SubjectGroup). The source table records all the pupils in a school with(amongst other things) a column (about 50) for each subject the pupilmight potentially sit. In these columns are recorded the study groupthat they belong to for those subjects. The destination table holds arecord per pupil per subject per term, against which the teacher willultimately record the pupils performance.The code as shown runs perfectly until the operator tries to insert aselection of records that include some that already exist. What I wouldlike it to do is, record those, which do not exist and discard theremainder. However, whenever a single duplicate occurs SQL rejects thewhole batch. I know that my solution will probably involve using the‘NOT EXISTS’ expression, but try as I might I cannot get it to work. Tofurther complicate things, the code is being run from within VBA usingthe RunSQL command.The variables ‘strFieldName’, ‘strGroup’ & ‘strTerm are declared at thestart of the procedure and originate from options selected on an Accessform.INSERT INTO dbo.yInterimReportData (PupilID, LastName, FirstName,TermID, SubjectGroup) SELECT PupilID, LastName, FirstName," & "'" &strTerm & "'" & "," & "'" & strGroup & "'" & "FROM dbo.Pupils WHERE (" &strFieldName & " = " & "'" & strGroup & "')Any Ideas?RegardsColin*** Sent via Developersdex http://www.developersdex.com ***
Hi I am trying to populate a table with 2 FKs as its PK (SiteID and ProductDescID). First 1) I add in all the products whose Manfacturer and Category are supposed to appear on the site and then 2) I add in all the extra products that are needed regardless of their manufacturer or category. The problem I am having is if the product has already been added to the ProductCatTable due to its Manufacturer or Cateogry but is also in the SatForceProduct table. The can’t insert duplicate PK error is thrown. I don’t know how to do this IF NOT EXISTS statement (or what ever else may be needed) so that I can check whether a line from the Forced table needs to be added. I am not passing in any parameters and I am expecting more than 1 line to be inserted in each of the statements. Please help -- 1) Populate INSERT INTO dbo.ProductCatTable (SiteID, ProductDescID) SELECT dbo.SatSite.SiteID, dbo.ProductDesc.ProductDescID FROM dbo.SatManu INNER JOIN dbo.ProductDesc ON dbo.SatManu.Manu = dbo.ProductDesc.Manu INNER JOIN dbo.SatCats ON dbo.ProductDesc.Cat = dbo.SatCats.Cat INNER JOIN dbo.SatSite ON dbo.SatManu.SatID = dbo.SatSite.SiteID AND dbo.SatCats.SatID = dbo.SatSite.SiteID 2) Add Force Ins IF NOT EXISTS(SELECT SiteID, ProductDescID FROM ProductCatTable WHERE ????????) BEGIN INSERT INTO dbo. ProductCatTable (SiteID, ProductDescID) SELECT SiteID, ProductDescID FROM dbo.SatForceProduct END Thanks in advance J
I have a 'Products' table (with: 'uid' and 'CatName' columns) and 'ProductCategory' table (with: 'uid', 'ProductID', 'CategoryID' columns).
I got stored procedure below to update or insert new row to 'ProductCategory' table whenever 'Products' table has been updated or new products has been added to it.
Update part works just fine but when new row has been added to 'Products' this storedProc dosn't insert it into 'ProductCategory' table, it does that only when 'ProductCategory' table is empty, I'm afraid it's because first column 'uid' in 'ProductCategory' table is an Identity column... I’m not sure how should I go about that problem. This is my stored procedure:
DECLARE @CatNo INT, @CatName varchar(10) SET @CatNo = 2 SET @CatName = 'bracket'
IF exists (SELECT ProductID from ProductCategory, Products where ProductCategory.ProductID = Products.uid and Products.CatName = @CatName ) BEGIN UPDATE ProductCategory SET CategoryID = @CatNo FROM Products WHERE Products.CatName = @CatName and ProductCategory.ProductID = Products.uid END ELSE BEGIN INSERT INTO ProductCategory ( ProductID, CategoryID) SELECT uid, @CatNo FROM Products WHERE Products.CatName = @CatName END
SET @CatNo = 3 SET @CatName = 'cable'
IF exists (SELECT ProductID from ProductCategory, Products where ProductCategory.ProductID = Products.uid and Products.CatName = @CatName ) BEGIN UPDATE ProductCategory SET CategoryID = @CatNo FROM Products WHERE Products.CatName = @CatName and ProductCategory.ProductID = Products.uid END ELSE BEGIN INSERT INTO ProductCategory ( ProductID, CategoryID) SELECT uid, @CatNo FROM Products WHERE Products.CatName = @CatName END (... Goes for another 37 categories)

In MS Access I can do in one SQL statement a update if exists else ainsert.Assuming my source staging table is called - SOURCE and my targettable is called - DEST and both of them have the same structure asfollowsKeycolumns==========MaterialCustomerYearNonKeyColumns=============SalesIn Access I can do a update if the record exists else do a insert inone update SQL statement as follows:UPDATE DEST SET DEST.SALES = SOURCE.SALESfrom DEST RIGHT OUTER JOIN SOURCEON (DEST.MATERIAL = SOURCE.MATERIAL ANDDEST.CUSTOMER = SOURCE.CUSTOMER ANDDEST.YEAR = SOURCE.YEAR)This query will add a record in SOURCE into DEST if that record doesnot exist in DEST else it does a update.

Here is the steps I should take... 1- Check for the log table and find run status ( there is a date field which tells the day run) 2- Lets say last day was 2008-05-15, So I have to check A1.DDDDMMYYY file exists in the folder for each day like A1.20080516,A1.20080517 and A1.20060518 ( until today) 3- if A1.20080516 text file exist then I have to move it to the table and same thing for other dates like if A1.20080517 exists I have to load it to table and so on
it looks like for each loop, first I have to get the last date and then I have to check the file exists for each date and if the date file exists then I have to load it into table...
Please tell me How can I do it. it looks complex looping...
I have an address table, and a log table will only record changes in it. So we wrote a after udpate trigger for it. In our case the trigger only need to record historical changes into the log table. so it only needs to be an after update trigger.The trigger works fine until a day we found out there are same addresses exist in the log table for the same student. so below is what I modified the trigger to. I tested, it seems working OK. Also would like to know do I need to use if not exists statement, or just use in the where not exists like what I did in the following code:
ALTER TRIGGER [dbo].[trg_stuPropertyAddressChangeLog] ON [dbo].[stuPropertyAddress] FOR UPDATE AS DECLARE @rc AS INT ;
Background: After Insert Trigger runs a sproc that inserts values into another table IF items on the form were populated. THose all work great, but last scenario wont work: Creating a row insert based on Checking that all 22 other items from the prior insert (values of i.columns) were NULL:
IF EXISTS(select DISTINCT i.notes, i.M_Prior, i.M_Worksheet, ... from inserted i WHERE i.notes IS NOT NULL AND i.M_Prior = NULL AND i.M_Worksheet = NULL AND...)
ID varchar (contains alphanumeric values,not unique) Territory (combined with ID unique) Total_Used int can be null Date_ date (date of the import of the data) ID Territory Total_Used Date_ ACASC CAL071287 2014-06-01 ACASC CAL071287 2014-08-01 ACASC CAL071288 2014-09-01

Now the problem,per month I need the most recent value so I'm expecting
Previously same records exists in table having primary key and table having foreign key . we have faced 7 records were lost from primary key table but same record exists in foreign key table.
Ok this is a simple question but i cant seem to find out how since i had the access of a query builder for web matrix.I have the following:A Table called Customer, with Cust_Name, Cust_phoneI have modified my CreateUserWizard to accomodate mroe text boxes which would finally store to vales for Cust_Name, Cust_phone.Question is how can i perform an INSERT query? or rather i noticed that the query builder doesnt allow me to, instead the query builder is towards inserting new records thur GridView and FormView.I've designed a query to handle wildcards i.e @Cust_Nameso i'm thinking if i can have a working insert statment i can do something liketbCust_name.txt = @Cust_Namethen finally perform the insert queryAny ideas? thanks
