I have a table that I would like to add new values to only if those values are not already in the DB.
The table has one Name column which has a unique key, so I only want to insert records if the new value for the name is not already in the database.
I could send everything to a loading table and then delete the duplicate records on that loading table and then copy the remaining records to my final destination, but I think that there should be a cleaner way.
I have 2 identical tables one contains current settings, the other contains all historical settings.I could create a union view to display the current values from table A and all historical values from table B, butthat would also require a Variable to hold the tblid for both select statements.
Q. Can this be done with one joined or conditional select statement?
DECLARE @tblid int = 501 SELECT 1,2,3,4,'CurrentSetting' FROM TableA ta WHERE tblid = @tblid UNION SELECT 1,2,3,4,'PreviosSetting' FROM Tableb tb WHERE tblid = @tblid
I am relatively new to SQL and as a project I have been asked to create the SQL for a simple database to record train details. I want to implement a check constraint which will prevent data from being inserted into a table if the weight of the train is more than the maximum towing weight of the locomotive. FOr instance, I need to add the unladen weight and maximum capacity of each wagon (located in the wagon type table) and compare it against the locomotive maximum pulling weight (the locomotive class table). I have the following SQL but it will not work:
check((select SUM(fwt.unladen_weight+fwt.maximum_payload) from hauls as h,freight_wagon as fw,freight_wagon_type as fwt,train as t where h.freight_wagon_serial_number = fw.freight_wagon_serial_number and fw.freight_wagon_type = fwt.freight_wagon_type and h.train_number = t.train_number) < (select lc.maximum_towing_weight from locomotive_class as lc,locomotive as l,train as t where lc.locomotive_class = l.locomotive_class and l.locomotive_serial_number = t.locomotive_serial_number))
The hauls table is where the constraint has been placed and is the intermediary table between train and freight wagon.
I may not have explained this very well; but in short, i need to compare the sum of two values in one table against a values located in another table...At present I keep getting a message telling me the sub query cannot return more than one row.
I have a table "abc" with there fields of same data type 'x','y','z'. 'x' is the primary key for the table 'abc', what I supposed to do is to copy the values under field 'y' to field 'z' irrespective of the values already with 'z'.
I'm guessing this is a fairly straight forward need, but want to make sure I am using the correct set of tasks:
In the dataflow, some values I need to carry forward from the previous row, such as a balance that I need to carry forward for the current customer record. This is similar to a running total, only I am not summing anything, but just carrying over from the previous records value (assuming dataset is sorted correctly, first by customer #, then by date).
Do I need the Dervied Column transform, and use a variable to store the previous value, or is there another transform that would be better suited?
I just discovered that a bigint column in one of my tables is getting it's values truncated when I run a DTS job to copy the data to another database. The DTS job is designed to refresh our test environments from our production database. All the other tables copy fine. This include another table that also contains a bigint column. But this one table consistenly has a problem where 60 or so records are translated from positive number to negative values. The only explaination I came up with was truncation at some point.
The following dbo.Tables of Northwind.mdf in my .SQLEXPRESS (SQL Server Management Studio Express) are missing: dbo.Categories dbo.CustomerCustomerDemo dbo.CustomerDemographics dbo.Customers dbo.Employees dbo.EmployeeTerritories dbo.Order Details dbo.Orders dbo.Products dbo.Regions dbo.Shippers dbo.Suppliers dbo.Territories.
But, I have these dbo.Tables in a different Database "xyzDatabase". How can I copy each of these dbo.Tables to the another blank dbo.Table of Northwind Database?
I right clicked on the dbo.Categories and I saw the following thing: dbo.Categories New Table... Modify Open Table Script Table as |> CREATYE To |> DROP To |> SELECT To |> INSERT To |> New Query Editor Window File.... Clipboard UPDATE To |> DELETE to |> From the above observation,I think it is possible to copy the dbo.Table from the one Database to the Northwind Database that needs to be repaired. Please help and advise me how to do this task or tell me where I can find the Microsoft document that gives the details of this X-copy thing.
Thanks in advance, Scott Chang
P. S. I am using VB 2005 Express to create a project to learn "Calling Stored Procedures with ADO.NET" (see Paul Kimmel's article in http://www.developer.com/db/article.php/3438221) that needs the dbo.Tables of Northwind Database and my Northwind Database has been screwed up for quite a while and needs a big repair.
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 need to replace all the "User Friendly Names" with "System Names" in the calculations, i.e., I need "Sales Units" to be replaced with "cSalesUnits", "AUR" replaced with "cAUR", "Comp Sales Units" with "cCompSalesUnits", and "Comp AUR" with "cCompAUR". (It isn't always as easy as removing spaces and added 'c' to the beginning of the string...)
I have created a CTE of all the "Look-up" values, and have tried all kinds of joins, and other functions to achieve this, but so far nothing has quite worked.
How can I accomplish this?
Here is some SQL for set up. There are over 500 formulas that need updating with over 400 different "look up" possibilities, so hard coding something isn't really an option.
Gurus, I have two list boxes, user can move items back n forth, from second listbox I am inserting values into a table. So far everything is working fine. Now I want to delete all the existing values from the table before inserting evertime..Please help me in this I dont know what to do. thanks kalloo
I'm trying to checking my production table table_a against a working table table_b (which i'm downlading data to)Here are the collumns i have in table_a and table_bDescription | FundID (this is not my PK) | Money I'm running an update if there is already vaule in the money collumn. I check to see if table_a matches table_b...if not i update table a with table b's value where FundID match up.What i'm having trouble on is if there is no record in table_a but there is a record in table_b. How can I insert that record into table_a? I would like to do all of this (the update and insert statement in one stored proc. if possible. )If anyone has this answer please let me know.Thanks,RB

Hi allI have two tables in SqlServer with Exactly Same Structure,I want to Copy all Records fromone of them to another one.I came across to "Insert....select..." statement But i have two problem 1) I don't know any thing about Columns name!!! i just know they have same structure and as far as i know , "Insert...select..." need the Column list to operate correctly, am i right? 2) these two table have One Prinary Key column with IDENTITY feature.

Hi i have set up two very simple tables, I want a user to be able to create a basic account ( data stored in User_Profile table with Id set as the Primery Key as Identity) I want the user to be able to be able to return to their account at a later date and then post multiple reviews of different bands they have seen at a later date. I kept the tables in my example very simple so I could get my head around the concept, but generally, I want to connect the Id (PK) value in User_Profile table to the User_Id filed in the User_Review table, so every review that user writes, will be connected directly to their Id.
Any help you could give would be fantastic a i have no idea where to start!!!
User_Profile
Id int, ( as primary Identity Key)
Name
City
Country
I have a second table called User Reviews
User_Revews
Revew_Id int , ( as primary Identity Key)
User_Id int, ( I want this to contain the Id value in the User profile Table)
Hi, All, I have agentID in product table. Now I add agentID column in transaction table. Now I want to copy all agentID from product table to transaction table based on the order_id in both table. Can you show me an example? Thanks Betty
When a record is inserted or updated records in Table1 I want a record to be inserted into table3 for each record ID that is in table2 if the table2.id does not already exist in table3. What is the best way to do this? Could this be done with a trigger? If it could how would I write such a trigger. I have never written one before and this sounds like a hand full for my first effort. Your help will be greatly appreciated.
I need to copy existing row data from one table into a new row in a different table, both in the same database. Can this be done in a stored procedure where the selected row is passed in as parameter value? Thank you,
Hello everyone, I have a local MSSQL server (I guess it's called MSDE), with some tables that I would like to use as a template for a set of new tables. I would simply like a Stored Procedure that takes these 3 tables, makes a copy of their structure (not data, since they will be empty), and name them by using a parameter given to the SP. I have made something that I thought would work, but after testing it a bit more, it seems to forget default values for the fields, which is of course not good enough :). I hope that someone can tell me how to duplicate these 3 tables, including every detail for the fields!
Hi.Like the title says - how do i do this?I was given the following example:INSERT INTO TABLE2 SELECT * FROM TABLE1 WHERE COL1 = 'A'The above statement threw the following error:An explicit value for the identity column in table 'TABLE2' can onlybe specified when a column list is used and IDENTITY_INSERT is ON.Then, after filling in all the column names in my above selectstatement I kept getting an error to the effect that the number ofsource and destination columns don't match. This is because one column"confirm_hash" does not exist in the destination table, just thesource table.could somebody show me how to get this to work?thanks!PS - MS SQL SERVER EXPRESS 2005
I want to put fields from four tables into one table. I created a new table, but how do i get the same fields from the other tables to this table along with primary and foreign keys.
I have a number of large tables (50,000,000 + rows and 30+ columns) that are refreshed once per month with data from another system. Data is first loaded into a staging table, that has an indentical strcuture to the final table, cleansed and then copy to the final table.
The current copy process is simple but inefficient:
Truncate Table <final-table> Insert Into <final-table> Select * from <staging-table>
If possible I don't want to use DTS for this and I'd like to use a batch size of around 10,000 rows to help reduce the size of the log file because I have 3 of these types of Inserts running concurrently.
