SQL - Insert Into Table Where Not Exists In Another Table
Mar 15, 2007
I am getting info from one table, CalibrationReview, that is not in
another table, tblEquipments.
SELECT EquipmentNumber, Model, SerialNumber, Make, CalLabName, CalDate
FROM CalibrationReview
WHERE NOT EXISTS (SELECT AssignedID FROM tblEquipments WHERE AssignedID = CalibrationReview.EquipmentNumber)
Now, I need to take these rows and INSERT them into tblEquipments,
but with some conditions.
tblEquipments has some contraints, so, the following needs to be done:
Using dbo.CalibrationReview.EquipmentNumber, get CalibrationMaster.TestTechnology where dbo.CalibrationReview.EquipmentNumber = dbo.CalibrationMaster.EquipmentID
Then take CalibrationMaster.TestTechnology and read tblTestTechnology.testTechnology and get tblTestTechnology.id
So,
tblEquipments.testTechnology = tblTestTechnology.id OR 1 if not found
WHERE dbo.CalibrationReview.EquipmentNumber = dbo.CalibrationMaster.EquipmentID and CalibrationMaster.TestTechnology = tblTestTechnology.testTechnology
And similar for CalibrationReview.CalLabName.
tblEquipments.calLab = tblLabs.ID where tblLabs.LabName = CalibrationReview.CalLabName
I hope this is clear as I can write this in code behind, but it's
much better using sql simply because it's faster and only needs to
be run once.
Inheriting databases and combining all of them to develop a large
.Net management system is fun, huh?
I need to find out if a Transaction ID exists in Table A that does not exist in Table B. If that is the case, then I need to insert into Table B all of the Transaction IDs and Descriptions that are not already in. Seems to me this would involve If Not Exists and then an insert into Table B. This would work easily if there were only one row. What is the best way to handle it if there are a bunch of rows? Should there be some type of looping?
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...
This is on Sybase but I'm guessing that the same situation would happen on SQL Server. (Please confirm if you know).
I'm looking at these new databases and I'm seeing code similar to this all over the place:
if not exists (select 1 from dbo.t1 where f1 = @p1) begin select @errno = @errno | 1 end
There's a unique clustered in dex on t1.f1.
The execution plan shows this for this statement:
FROM TABLE dbo.t1 EXISTS TABLE : nested iteration. Table Scan. Forward scan. Positioning at start of table.
It's not using my index!!!!!
It seems to be the case with EXISTS statements. Can anybody confirm?
I also hinted to use the index but it still didn't use it.
If the existence check really doesn't use the index, what's a good code alternative to this check?
I did this and it's working great but I wonder if there's a better alternative. I don't really like doing the SET ROWCOUNT 1 and then SET ROWCOUNT 0 thing. SELECT TOP 1 won't work on Sybase, :-(.
SET ROWCOUNT 1 SELECT @cnt = (SELECT 1 FROM dbo.t1 (index ix01) WHERE f1 = @p1 ) SET ROWCOUNT 0
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.
I have created a table Table with name as Varchar and id as int. Now i have started inserting the rows like, insert into Table values ('arun',20).Yes i have inserted a row in the table. Now i have got the values " arun's ", 50. insert into Table values('arun's',20) My sqlserver is giving me an error instead of inserting the row. How will you solve this problem?
I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual (empno, accrued_vacation, accrued_sick_effective_date, accrued_sick, import_date)
For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.
Say you have a fact table with a few columns that all reference the same key column in a dimension table, you want to write a view to return the information for those keys?
USE MyTestDB; GO SET NOCOUNT ON; IF OBJECT_ID ('dbo.FactTemp' ,'U') IS NOT NULL DROP TABLE dbo.FactTemp;

I'm using very small data at the moment, and the query plan and statistics don't really say which way.
table2 is intially populated (basically this will serve as historical table for view); temptable and table2 will are similar except that table2 has two extra columns which are insertdt and updatedt
process: 1. get data from an existing view and insert in temptable 2. truncate/delete contents of table1 3. insert data in table1 by comparing temptable vs table2 (values that exists in temptable but not in table2 will be inserted) 4. insert data in table2 which are not yet present (comparing ID in t2 and temptable) 5. UPDATE table2 whose field/column VALUE is not equal with temptable. (meaning UNMATCHED VALUE)
* for #5 if a value from table2 (historical table) has changed compared to temptable (new result of view) this must be updated as well as the updateddt field value.
I have a textbox1 control where a zip code is entered. What is the most efficient way in C# code behind to see if that zip code exists in tblZipCode? I only need to know if it is there, do not need to know how many occurances.
HI, having a problem with a data loading from 2005 to 2000. Im using export & import wizard. But the problem comes when the user drops a table on 2005. Anyway to check if table exista then use the E&I to load the data. I cant use the BCP as xp_shellcmd is disable.
Hi all,I am in the process of creating a page that checks to see if a particular user exists in the database and if it does then send to welcome.aspx if not then accessdenied.aspx. The userid is requested from the query string.I have done some research and cannot find anything directly related, I have tried to add bits of code into what i think is the right place but I dont think what i am doing is correct. Can someone help and show me where my code is going wrong? Also is there a better/more efficient way to do what I am doing?Thanks in advance. default.aspx.csusing System;using System.Data;using System.Data.SqlClient;using System.Configuration;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;public partial class _Default : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { string UserID = Request.QueryString["uid"]; //string TransferPage; if (UserID != null) { //initiate connection to db SqlConnection objConnect = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["MyConnection"].ConnectionString); string sql = "SELECT COUNT(*) FROM members WHERE UserID = '" + UserID + "'"; SqlCommand query = new SqlCommand(cmd, test); int count = (int)query.ExecuteScalar(); int aantal = -1; // some default value if can't insert record if (count == 0) // no existing record for username { Server.Transfer("accessdenied.aspx"); } else { Session["UID"] = UserID; Server.Transfer("welcome.aspx"); } } }}
i am using vb.net and ms sql server 2005 express.....what is the syntax for dropping a table if existsi have used this but it says incorrect syntax near if Dim cmda As New SqlCommand("drop table " + test + " if exists", New SqlConnection(strdb)) cmda.Connection.Open() cmda.ExecuteNonQuery() cmda.Connection.Close()any solutions???? plz only answer in vb.net and sql server express
What is the best way to programmatically determine if a temp table exists? In 6.5, I would use
IF EXISTS(SELECT * from tempdb..sysobjects where id = object_id('tempdb..#MyTable') and type = 'U')
But now that it is strongly discouraged to code against system tables, how could I re-write this statement?
The proper way to check the existence of a table would be:
IF OBJECTPROPERTY(object_id('tablename'), 'IsTable') = 1
However, to get this to run for a temp table, I think you'd have to change the database context to tempdb and then back to your database. That doesn't seem efficient.
I could use
IF object_id('tempdb..#MyTable') IS NOT NULL
But that's not guarenteeing that it's a table, right?
How do I find out if a temporary table named '##test' exists? I have a stored procedure that creates this table and if it exists another stored procedure should do one thing, if it does not exist I want the SP to do something else. Any help as to how I can determine if this table exists at the current time would be greatly appreciated.
This my first time using the link server to read the files directly from within SQL2005, so issues the following link:-
EXEC sp_addlinkedserver @server = N'MYVFPSERVER', -- Your linked server name here @srvproduct=N'Visual FoxPro 9', -- can be anything @provider=N'VFPOLEDB', @datasrc=N'"C:PROGRAM FILESMICROSOFT VISUAL FOXPRO 9Samplesdata estdata.dbc"'
After that i can open query and do the import issues, but how can check if the table exists before issues the query.
Hi,I am trying to create a script that deletes transaction tables and leavesmaster data like customer, vendors, inventory items, etc. How can I useTRUNCATE TABLE with an Exists? My problem is I have 200+ tables, if Isimply use a list like:truncate table01truncate table02truncate table03....I get errors if the table does not exist and have to manually run thetruncate statements. Some tables may not exist if that part of the app isnever used. I'm trying to make a list of all tables that could existwithout it erroring out 50+ times.Thanks in advance.
Hi... I was hoping if someone could share me some thoughts with the issue that I am having at the moment.
Problem: When I run the package in my local machine and update local SS DB/table - new records writes OK in the table. BUT when I changed my destination meaning write record into another physical SS DB/table there is no INSERT data occurs. AND SO when I move/copy over that same package into another server (e.g. server that do not write record earlier) and run it locally IT WORKS fine too.
What I am trying to do is very simple - Add new records in a SS table using SSIS . I only care for new rows and not even changed rows. Here is my logic - 1. Create Ole DB source to RemoteSERVER - using SELECT stmt 2. I have LoopUp component that will look for NEW records - Directs all rows that don't find match and redirect rows (error output). 3. Since I don't care for any rows that is matched in my lookup - I do nothing or I trash the rows 4. I send the error rows (NEW rows) into OleDB destination
RESULTS when I run the package locally and destination table is also local - WORKS FINE; But when I run the package locally and destination table is in another Sserver (remote) - now rows is written.
The package is run thru BIDS manually so there is no sucurity restrictions attached to it.
I am not sure what I am missing. And I do not see error in my package either. It is not failing.
I have SQL Server Management Studio Express (SSMS Express) and SQL Server 2005 Express (SS Express) installed in my Windows XP Pro PC that is on Microsoft Windows NT 4 LAN System. My Computer Administrator grants me the Administror Privilege to use my PC. I tried to use SQLQuery.sql (see the code below) to create a table "LabResults" and insert 20 data (values) into the table. I got Error Messages 102 and 156 when I did "Parse" or "Execute". This is my first time to apply the data type 'decimal' and the "VALUES" into the table. I do not know what is wrong with the 'decimal' and how to add the "VALUES": (1) Do I put the precision and scale of the decimal wrong? (2) Do I have to use "GO" after each "VALUES"? Please help and advise.
Thanks in advance,
Scott Chang

I'm trying to insert data into a table from two tables into a single table along with a hard coded value.
insert into TABLE1 (THING,PERSONORGROUP,ACCESSRIGHTS) VALUES ((select SYSTEM_ID from TABLE2 where AUTHOR IN (select SYSTEM_ID from TABLE2 where USER_ID =('USER1'))),(select SYSTEM_ID from TABLE2 where USER_ID =('USER2')),255)
I get the following-
Msg 512, Level 16, State 1, Line 1
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
My question is: How can I insert a row for each unique TemplateId. So let's say I have templateIds like, 2,5,6,7... For each unique templateId, how can I insert one more row?
SET @QUERY = "INSERT INTO tblDocTable(FileName, FileType, ImportExportID, BuildingID, Document)
SELECT '"+@fName+"' AS FileName, '"+@fType+"' AS FileType, " + cast(@fID as nvarchar(18)) + " as ImportExportID, '"+@bID+"' AS BuildingID, * FROM OPENROWSET( BULK '" +@fPath+"' ,SINGLE_BLOB)
AS Document"
EXEC (@QUERY)
This puts some values including a pdf or .doc file into a table, tblDocTable.
Is it possible to change this so that I can get the values from a table rather than as parameters. The Query would be in the form of: insert into tblDocTable (a, b, c, d) select a,b,c,d from tblimportExport.
tblImportExport has the path for the document (DocPath) so I would subsitute that field, ie. DocPath, for the @fPath variable.
Otherwise I can see only doing a Fetch next from tblIportExport where I would put every field into a variable and then run this exec query on these. Thus looping thru every row in tblImportExport.
What’s the easiest way to check if a single value exists in a table column? I’m building a simple login page, and I want to get the username and check if it exists in my Users table. Here’s my SQL: SELECT UserID FROM UsersWHERE UserID = "admin" Could someone give me code to check for “admin” in my UserID column? Here’s some code I tried, using my SqlDataSource, but it returns an error “Could not load type 'System.Data.OleDb'” protected void Button1_Click(object sender, EventArgs e) { // Retreive the results from the SqlDataSource as a DataReader OleDbDataReader reader = (OleDbDataReader) SqlDataSource1.Select(DataSourceSelectArguments.Empty); // Read in the value if (reader.Read()) { } // Close the reader reader.Close(); } I don’t have to use the SqlDataSource, but originally thought it might be easier. I know how to use SqlDataSource to fill a whole GridView but this is different.
Basically, i am still relatively new to ASP.net and SQL. And i have the following query. I have a skills table to which the user enters their skills using the following fields: Skillcatagory, SKill, Current Level, Target Level, target date and comments and the serial of the user. I need to check via our staff table, which people have had a skill entered for them. And then produce a report on who has not had a skill entered for them. This table has a serial of the user column aswell which is unique. If there is more information that i can give you to assist me, please ask me. You help would be greatly appreciated.
I need to do some processing but only if a specific table 'table1' exists in the SQL Server database. How can I check if this 'table1' exists using either ADO.Net code or SQL Server query?
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.
