Changing A Record After Comparing One Database Table To Another
May 26, 2007
I'm using SQL Server 2005 Express.
In my main database table I have many fields but the two following fields are my main concern.
1) email_address
2) unsubscribe
In my secondary database table I have one record only.
1) email_address
What I want to accomplish... I want to compare the email_address of the secondary database table to the email_address of the main database table and if it exist, change the value of the unsubscribe field. (or if I can't do that, then delete the record within the main database table completely.)
SELECTIndustry, 100.0 * SUM(CASE when ceoischairman = 'yes' then 1 else 0 end) / COUNT(DISTINCT CompID) AS [YesPercent], 100.0 * SUM(CASE when ceoischairman = 'no' then 1 else 0 end) / COUNT(DISTINCT CompID) AS [NoPercent] FROMTCompanies GROUP BYIndustry ORDER BYIndustry
This code above is working as I need it but I need to insert some additional functionality. Thanks
I need to add something like this:
IF YesPercent > NoPercent UPDATE tableX SET CEOIsChairman='Yes' WHERE Industry='<the industry value being evaluated>' Else If NoPercent > YesPercent UPDATE tableX SET CEOIsChairman='No' WHERE Industry='<the industry value being evaluated>' Else UPDATE tableX SET CEOIsChairman='Equal' WHERE Industry='<the industry value being evaluated>' End
I am trying to pull the records which are being affected i.e, comparing the values and if not same then populating the record.
I am using the below condition in where clause however i am getting runt time error as "Conversion failure when converting date and/or time from character string"
Condition in Where clause:
cast(isNull(tab1.Col1,'') as datetime) <> cast(isNull(tab2.col1,'') as datetime)
Hi guys, may I know is it possible to create an update trigger like this ? Assuming there are two database, database A and database B and both are having same tables called 'Payments' table. I would like to update the Payments records on database A automatically after Payments records on database B had been updated. I can't use replication because both tables might having different records and some records are the same. Hope can get any assistance here, thank you.
I have the problem of dynamically changing a field value in a row depending on the value of the same field in the previous row, assuming the table is sorted on that field. :( You may consider that field as a key of same sort as other values in the table do not help in selecting them uniquely. Ex. Before After 130 -> 130 130 -> 130A 140 -> 140 140 -> 140A
Got a question here and as I am no expert programmer, this should be easy for you gurus. I have this fairly generic code I've created where I return data from an SQL table in a DataList control. I want to take it to the next level and return only the last record in the table, but I am unsure of how to do that. Perhaps I shouldn't even be using a DataList control, I'm not sure.
I don't work much with the back end of software development so there is a lot about SQL Server I do not know. We are building a database. The database will have about 10 tables in it. 3 of these tables will probably have a huge amount of data in them. Specifically each one of the 3 tables will each have about a half a million database records in it. Each record is about 100 characters max in length.(Im am including numbers as characters and summing the individual columns/fields to come up with 100). Will a SQL server database table with A half a million records in it be possible? We have tried to normalize the database to cut down on the size of the table but it all comes out to about a half a million records per table. Any help is deeply appreciated. Bill
I have two tables in my database: order_id with fields order (text) and comp_ID (int) and another table called customers with comp_ID (int) and company name (text) and other company information fields. The link between the two tables is the comp_ID. With every order that's made the company that made the order is stored with it in the order_id table. If I type in the order id (text), I want to be able to use the order id to search the order_id table and find out what the comp_ID of the company that made that order is. Then use that comp_ID to pull up the record of company information from the customers table with the same comp_ID. Is there some way to do this in one query? Or how do I accomplish this?
,I am creating a database where each record is required to have a twin record in the database.These is a type a value and a type b value and both must be present for the record to be valid.
Customer_ID, Order_Type, Product_Code 54, a, 00345 54, b, 00356
Is this something that would have to be done programmatically, or is it possible to create a constraint of some sort to ensure this?
I am creating a simple application form using visual studio 2015. I can create database.mdf successfully and create dbo.table successfully. but when i tried to view table by expanding the table icon on the server explorer, the table should be able to show list of table but it didn't show any record and why is it like that.
I would like to know whether it is possible to add and updated date column in a slow changing dimension table using the slow changing dimension data flow transformation.
I would like to keep track of what record is updated in the dimension table based on the data being processed.
I want to be able to open URLs in a new window in my SSRS report, and the URLs keep changing in every record. The problem is these links are not the only things present in the record, and there is other data present. I keep seeing examples where they are considering only a link to be present in the record with no other data.
Also the data in the record includes HTML tags and I checked the option that says "HTML - Interpret HTML tags as styles" on the placeholder properties window.
Example of data in the record: Hello! Welcome to google, the most used search engine. Click on www.google.com to go the website
So when I click on the www.google.com URL, it should open in a new window.
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
In my production box is running on SQL7.0 with Merge replication and i want add one more table and i want add one more column existing replication table. Any body guide me how to add .This is very urgent Regards Don
Is that possible to restrict inserting the record if record already exist in the table.
Scenario: query should be
We are inserting a bulk information of data, it should not insert the row if it already exist in the table. excluding that it should insert the other rows.
Hi All,I have a table in SQL Server 2000 that contains several million memberids. Some of these member ids are duplicated in the table, and eachrecord is tagged with a 1 or a 2 in [recsrc] to indicate where theycame from.I want to remove all member ids records from the table that have arecsrc of 1 where the same member id also exists in the table with arecsrc of 2.So, if the member id has a recsrc of 1, and no other record exists inthe table with the same member id and a recsrc of 2, I want it leftuntouched.So, in a theortetical dataset of member id and recsrc:0001, 10002, 20001, 20003, 10004, 2I am looking to only delete the first record, because it has a recsrcof 1 and there is another record in the table with the same member idand a recsrc of 2.I'd very much appreciate it if someone could help me achieve this!Much warmth,Murray
I have a customer table with a postcode and a suburb fields and cutomer info which is manually entered by data entry people...
I am trying to compare the entries against a postcode table with the correct postcodes which have fields postcode and suburb and based on the postcode entered in the customer table it should be the same as the suburb in the postcode table, if they are not the same output them to a table for manual checking..How would I go about this
Hi, Lets suppose i am having 2 database that is Database1 and Database2 Then both datbases are same having same number of tables, sp's, vies and etc. Then wht i have done is i have added two tables in database1 tb23 and tb24, and at the same time i have added one table out of these two table that is tb23 in the database2, Now i want a querry by using that querry i am able to find out that how many objects are there that are present in database1 but not in database2. Basically i want to do comparison in between two databases. ANY QUERRY, OR ANY TOOL by using which we can acheive this..... HOW????
I would like to compare some values in two columns which are in the same table. I want to check that there are no differences between the values if the ID is Test1 and Test2
Example table
IDValue1Value 2 TEST1HouseTango TEST2HouseTango with test as ( select * from ExampleTable where ID= 'TEST' ),
I have two name columns in my table, NAME1 & NAME2 that I want to compare to see if they match. Only problem is that the order of the first, last, middle name can be either same or different between the two fields.
For example NAME1 = JAY JOHN SMITH NAME2 = JOHN SMITH JAY or SMITH JOHN JAY
Is there a way to somehow reorder these fields and then compare using SQL?
I have a list of names, all i have to do is check to see if any of them are in a table, if they are they get deleted. The unique field of the table is title and it is what i have. I don't really know how i am meant to do this. I thought of creating a new table, placing my values into it and comparing to the already existing table, but surely their is a simple way?
There are two tables in my Database, tb1 and tb2 which both have the same attribute ID. I would like to ensure that there is nothing in ID in tb1 which is not listed in ID in tb2, can anyone help?
Can anyone tell me how a program like this might work:http://www.red-gate.com/products/SQ...mpare/index.htmI want to backup databases into a central repository but I only wantthe records that have changed for that day. This program seems to do itefficiently. Does Sql Server, Oracle, etc offer any sort of built inway of doing this via metadata or a similar mechanism?I want to be able to mirror databases in such a way that I dont need tohave the admin password for them. I don't want to alter the databaseschema in any way.The only way I can think off the top of my head is to assign MD5checksum values to rows and then compare the checksums in the masterand copy, however, to do it efficiently, you'd have to save the MD5values as you go, which would involve altering the schema on the mastertable.
have to recordsets with the following with the following SQL
SELECT place, count(minus)as countminus order by place group by place
THE RESULT WOULD BE
PLACE countminus
ABC 10 DEF 50 HIJ 5 KLM 2 MNO 0
MY OTHER QUERY IS SELECT plus, count(plus) as countplus GROUP BY plus ORDER BY plus
THE RESULT WOULD BE:
PLUS COUNTPLUS
ABC 10 DEF 20
my problem is i need to add another column to the first resultset (if possible) or create a table with the same field and values of the first result set with the additional column OF THE second resultset COUNTPLUS...
with this condition..
I need to loop with single row from the column PLACE on the first result set and compare it with the column PLUS on the second result set. if there is a value of the PLACE=PLUS get the corresponding value of the COLUMN COUNTPLUS AND WRITE it on the COUNTPLUS ON THE NEW TABLE.. ELSE THE VALUE IS 0 this i would do it up to the END OF FILE EOF...
THE RESULT WOULD BE THIS.....
PLACE countminus COUNTPLUS
ABC 10 10 DEF 50 20 HIJ 5 0 KLM 2 0 MNO 0 0
I WAS WORKING ON THIS BUT COULDN'T GET THROUGH IT ANYTHING WOULD BE A BIG HELP FOR ME FROM YOU GUYS
How do I only select rows with duplicate dates for each person (id)? (The actual table has approximately 13000 rows with approximately 3000 unique ids)
I have an entry form allowing customers to enter up to 15 skus (productid) at a time, so they can make a multiple order, instead of enteringone sku, then submitting it, then returing to the form to submit thesecond one, and so forth.From time to time, the sku they enter will be wrong, or discontiued, soit will not submit an order.Therefore, when they are done submitting their 15 skus through the orderform, I want a list showing them all of those skus that came back blank,or were not found in the database.I'm doing this by creating two tables. A shopping cart, which holds allthe skus that were returned, and a holding table, that holds all theskus that were submitted. I want to then delete all the skus in theholding page that match the skus in teh cart (because they are goodskus) which will then leave the unmatched skus in the holding table.I'll then scroll out the contents of the holding table, to show them theskus that were not found in the database.(confused yet?)So what I want to do is have some sql that will delete from the holdingtable where the sku = the sku in the cart. I've tried writing this, butit dosn't work.I tiried this delete from holding_table where sku = cart.skuI was hoping this would work, but it dosn't. Is there a way for me to dothis?Thanks!Bill*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
I would be very grateful if someone could help me. I have very little SQL knowledge and would like a push in the right direction:
I have a application that receives GPS lattitude and longitude values. I was originally using file base system where I would load all the points from the file into memory and do the calculations in the software but I now would like to use SQL Server Express.
I have created the tables:
[Table 1] GPS Points: id int Primary key latitude real longitude real desc nvarchar(128)
[Table 2] GPS Locations (comprises of one or more GPS Points from [1] above) to form a boundary: GPS Locations database structure is: locationId int primary key gpspoint1 int gpspoint2 int gpspoint3 int gpspoint4 int desc nvarchar(128)
Table 2 contains up to 4 gps points ids from table 1 and GpsPoints1-4 can be null.
I have created the tables and I have inserted GPS values into both tables.
My problem: I am trying to compare the current Lat/Lon (which are passed into the SQL fuction as two real datatype value) and I want to return all Table 2 locationId's where the current Lat/Lon are withing GPSPoints1-4 area. gpspoint1, gpspoint2, gpspoint3, gpspoint4 reference an id from Table 1. I am not sure how I can do this?
I have implemetned a SQL function that returns all points from Table 1 that are within the predefined radius of 1.5 miles from the current Lat/Lon values passed in.
where 3963.191 is earths radius in miles, radius is 1.5, @LatDec is the current latitude and @LonDec is the current longitude
Uses a lot of Trig and (for me) is quite complicated. This works very well and is very accurate. It also only uses a single table. I want to be able to now look for the current position within a boundary of 3 or more positions from Table 1 and this is where I am struggling?
Also, any suggestions on how I could do this better would be very much appreciated?
