Checking Whether Record ID Exists In Another Query
Jan 10, 2014
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 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. Protected Sub BTNCreateProdIDandName_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BTNCreateProdIDandName.Click ' Define data objects Dim conn As SqlConnection Dim comm As SqlCommand

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 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.
If you want to do a similar concept to Jamie's blog post above, but with the Konesan's Checksum Transformation to quickly compare MANY fields, you can visit here: http://www.ssistalk.com/2007/03/09/ssis-using-a-checksum-to-determine-if-a-row-has-changed/
I know there is a way to determine if a file exists using T-SQL, but I can't seem to find a way to determine if a directory exists. I need to be able to determine this so I can delete the directory if it already exists before I run other queries.
I would like to be able to check if a certain entry exists in a SQL table. Ideally, the output would be a boolean so I can use it in an IF statement which would tell it what to do depending on whether or not the entry exists. Thanks for anyone that helps. :)
I am getting an error between the IF THEN Else statement. The copy works after the THEN! I need some help!

I have two tables with script in a view. 1. newusers 2. blacklist I want to compare that "PresentEmail, RemoteComputer,Email" thats in newuser table is not in blacklists, and if this is true, then copy from newuser (the record not on blacklist) to blacklist using a where statement for second condition.
IF (NOT EXISTS (SELECT * FROM newusers AS d WHERE ISNULL(PresentEmail, 'NULL') IS BadEmail))
THEN
Insert into blacklist (BadNewEmail, BadIpAddress, BadEmail)
I'm trying to put scripts to create our stored procedures under version control.
However I don't want these scripts to be run if the stored procedure already exists (we'll be using update scripts to alter existing stored procedure I think).
Anyway I tried :
Code:
SET QUOTED_IDENTIFIER OFF GO SET ANSI_NULLS ON GO
/****** Object: Stored Procedure dbo.getEnglandHotelsByATOPResort Script Date: 26/10/2005 10:40:01 ******/ if NOT EXISTS (SELECT object_id('procedureName','p')) CREATE PROCEDURE [dbo].[procedureName] @location char(2) AS ...Procedure...
GO
SET QUOTED_IDENTIFIER OFF GO SET ANSI_NULLS ON GO
I know that the if NOT EXISTS ... part works as doing the following returns the expected result :
Code:
IF NOT EXISTS (SELECT object_id('procedureName','p')) SELECT 'FALSE' ELSE SELECT 'TRUE'
However when trying to do this before the CREATE PROCEDURE I get :
Server: Msg 156, Level 15, State 1, Line 4 Incorrect syntax near the keyword 'PROCEDURE'. Server: Msg 137, Level 15, State 1, Line 12 Must declare the variable '@location'.
I have a table called as Events and below are its columns
ID int EventFromDate datetime EventToDate datetime EventDesc nvarchar IsHoliday bit
This is a master table where the admin would enter the Events/Holidays for the entire year.
The data would be as below:
IDEventFromdateEventTodateEventDesc isHoliday 126-01-201526-01-2015RepublicdayYes 230-01-201531-01-2015TeamOutingNo 301-05-201501-05-2015Labour day Yes
Now, suppose a employee applies leave on 26/01/2015 to 26/01/2015 then it should not insert into table and return a value "Not updated"
How to handle the scenario if a employee applies leave between the range 23/01/2015 to 27/01/2015, since 26/01/2015 is a holiday in between. how the data can still be inserted excluding 26/01/2015
Can we exclude a non-working day or a sunday.
Leavedetails table to insert leaves applied by employee is as follows
LeaveDetailID int LeaveTypeId int FromDate datetime EndDate datetime Remarks nvarchar
I have 1+ CSV files (using a foreach loop) which I'm doing a lot of transform work on and then inserting into a SQL database table. Each CSV file usually contains about 2 days worth of data (contains date stamps) - somewhere in the region of 60k records per day. The destination table currently contains 3 million+ rows and will get bigger. I need to make sure that before inserting into the destination table, the data doesn't already exist.
I've read the following article: http://www.sqlis.com/311.aspx While the lookup method works, it takes ages and eats up memory as it caches the 3m+ records before running for each CSV. Obviously this will only get worse as the table grows in size.
To make things a little more efficient what I'd like to do, is first derive the dates I'm dealing with in the current file - essentially storing the max(date) and min(date) in variables. Then in the lookup SQL use those vars, to reduce the amount of data that needs to be brought into the transformation to check against before inserting into the destination table. Lookup SQL eg. SELECT * FROM MyTable WHERE Date BETWEEN varMinDate AND varMaxDate.
Ideally I'd use an aggregate transformation and then use the subsequent output from that either in the lookup query or store the output in vars, but I don't think you can do that and I get the feeling I'm approaching this with the wrong mindset.
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...)
Good morning everyone I am writing a windows forms application that will work similar to the windows messenger popup. I need this application to display a message to the user whenever a record is added to table in my DB. Any help would be appreciated in explaining how I can check the DB for new records.
I am trying to write a trigger that, on an update, will check to see if more than one record is being updated. If more than one record is being updated, rollback the transaction and print a message. If not, then commit the transaction and print an OK message.
My problem is I am having troubles writing this trigger. I will post my SQL trigger code so far.
I am new with Triggers, so any help or advice is appreciated.
Code:
CREATE TRIGGER trgPaperCheck ON BOOK AFTER UPDATE AS IF UPDATE(Paperback) BEGIN DECLARE @count AS INT SELECT @count = COUNT(Paperback) FROM Book IF @count > 1 BEGIN PRINT('Only one Book record can be updated at a time!') ROLLBACK TRANSACTION END ELSE IF @count =1 BEGIN PRINT('Paperback Updated') COMMIT TRANSACTION END END
Hello, I am using sql server 2000 as my backend.If there is any null record in my table , I am getting following error:*********** Conversion from type 'DBNull' to type 'String' is not valid. ************** to overcome this error I want to check if its null then don't do anything else do something.I have tried like this:If rs.fields("ph").value="NULL" thenelse.................end if But this does not solve my problem.Please help me i anyone can.Thanks.
Hello, I have an SSIS package that affects data in fourteen tables. This SSIS packge is supposed to insert, update, delete and apply various business rules to the data in the new database tabes in the same way that it occurs in the DTS package that affects the old tables in the former database.
After both the DTS packge and SSIS packages are run, the data in the fourteen tables from both databases need to mirror each other. I figure this is the best way that I can know that the new SSIS package is working correctly.
Is there something I can do in an SSIS package that can compare all of the tables between the two databases, record for record then (maybe as error output) produce output in the case where a mistmatch was detected between two given tables? Would a lookup transformation be helpful for this kind or thing, or should I think about doing it some other way?
The old database is on SQL Server 2000, and the new one on SQL Server 2005 64 bit. I've run into problems creating a linked server between the two to where I could just run queries to do this kind of check.
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 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
/*if key values exist don't insert new record*/ SELECT
/*if exists don't insert*/ CASE WHEN ISNULL(gradeId, -1) = -1 THEN INSERT INTO tblScores (gtStudentId, assignmentId, score) VALUES (@nStudent, @nAssignment, 0) END
FROM tblScores WHERE gtStudentId = @nStudent AND assignmentId = @nAssignment
tblScores has two fields comprising its primary key (gtStudentId, assignmentId) and the gradeId field is a required filed in this table.
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 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 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
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
Hi, I remember seeing a fancy query that checked for multiple fields in a table (I think using a select statement in the where clause but not sure), but can't remember how to do it... here is what I want to do (and maybe there is a much easier way). Thanks!
Table1 id item color 1 shoe red 2 shoe blue 3 coat green 4 coat black
Table2 item color shoe red coat green
I want everything in Table1 where item and color are not a match.
So my results should be: 2 shoe blue 4 coat black
I'm sorry if this is a dumb question... it's been that kind of a day!
We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.
If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.
Thanks, Sarah
The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.
This is running on a Websphere Application Server v6.1.
Suppose I have two tables(Customer and Order) which are as follows:
Code: Customer customer_id first_name
[Code]....
Another thing I am concerned about is that in the line INNER JOIN Order ON Customer.customer_id = Order.customer_id , I have written Customer.customer_id on the left hand side. Is that correct or I should write it on the right hand side of the equal sign?
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
[Code] .....
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.
