I want to change duplicate data in my sql server column.
the data= 'Barack Obama' , what I want
'Barack Obama 23453'
I have the following query:
UPDATE klant SET naamvoornaam=naamvoornaam + CAST(klantnummer AS VARCHAR)
WHERE naamvoornaam NOT IN (
SELECT(naamvoornaam)
FROM klant
GROUP BY naamvoornaam
HAVING ( COUNT(naamvoornaam) = 1 ))
Message from messages:
String or binary data would be truncated.
I think the max length exceeds the length of the destination column. I've tried:
Max(Len(naamvoornaam + CAST(klantnummer AS VARCHAR)))
message from messages:
An aggregate may not appear in the set list of an UPDATE statement.
This probably has been addressed before but I was unable to get the search to work properly on this site. I am needing a script/way of deleting all rows from a DB with the exception of one record left for each row that has duplicate column data. Example : Row 1 Field1 = 12345 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc. Row 2 Field1 = 12345 Field2 =zzzzzz Field 3=xxxxxx Field4=yyyyyy etc. Row3 Field1 = 12345 Field2 =20202 Field 3=11111 Field4=zzzzz etc. Row 4 Field1 = 54321 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc. Etc. Etc.
I want to be able to find the duplicates for Field1 and then delete all but 1 of those rows.( I don't care which one I keep just so only one is left.) The data in the other fields may or may not be unique.
I know how to find the duplicates it's just the deleting part I am having problems with. Any help would be much appreciated. Thanks,
I have a results table that was created from many different sources in SSIS. I have done calculations and created derived columns in it. I am trying to figure out if there is a way to remove duplicate rows from this table without first writing it to a temp sql table and then parsing through it to remove them.
each row has a like key in a column - I would like to remove like rows keeping specific columns in the resulting row based on the data in this key field.
How do I programatically change a column (say username) in a table (say tblusers) from varchar(25) to varchar(100)I am looking for something likealter tblusers set username as varchar(100) I know the above statement in nonsensical but it conveys the idea.
I would like to change column data in all tables in a single database at once.
For instance, i have many tables in a database, and about 30% of the tables has the column "orderplace". And all the data in orderplace (every tables in the database) are "houston". instead of going to each table and "update table set orderplace = 'dallas' " .... is there anyway that i could run a sql statement and it will update all the tables in database that has the orderplace column to "orderplace = 'dallas' " ?
How to modify/change data that is in a SQL table column. Here is what I need or have
I have 2 tables, Table 1 and Table 2, within those 2 tables there is 1 Column that has the same column heading aswell as data within,(I will call it the serial_number column) there is also a 2nd column that is labeled the Same in both tables, I would like to be able to update the Values in the 2nd column of table 1 with the values from table 2 column 3, using the Serial_number column as my matching reference between the 2, the data is not in the same order between the 2 Tables,
More or less I need to set the value of table 1/column 2 to match table 2/column 3, where the serial_numbers are the same in both tables serial_number columns, the data being changed is set as Small int...
I have a table say Friend which has a column "IsSingle VARCHAR(10)" and this column has values like yes or No Now I want to change type of column IsSingle from VARCHAR to BIT, if I try to do it manaually SQL throws error that cannot convert yes to bit etc. I know that we can write a script to do this task but i dont know how ? Any pointers,links, suggestions will help me to start with.
I need to change the value of column mimetype in table data, but only for these entries which have the value 144 in column "Subtype" in table dtr.
Here is my sql:
with cte as ( select DataID, SubType, MimeType from dtr A1, data A2 where A1.dataid=A2.Docid And A1.Subtype='144' AND A2.mimetype='application/news-message-id' ) update cte set MimeType = 'application/x-outlook-msg'
I've tested it and it works. Do you see any problems with this SQL?
As updates are risky I'll do a database backup. Is it possible to get all changed entries so that I can track my update, because I don't have a report about the changes? Maybe that everythin is transferred to an output file?
I am using SQL Server 2000 Enterprise Edition fully patched. Database is in Simple Recovery mode.
I need to change a column's data type from "int(4)" to "smallint(2)". I know for sure that there will be no data (precision) lost, because I know the possible values that this column could have.
My problem is that the table I am dealing with has 600,000,000 records in it. I dropped all indexes before I tried to alter the table. But still it is taking forever and filling up my 280GB disk with transaction log file.
I know that in Oracle, if I want I can turn off logging and do these kind of modifications relatively faster.
I was wondering if there is a way of disabling logging before running this alter command.
What is the best practice to handle a situation of this sort?
I have a query that produces unique rows. However, some of the unique rows have the column called testname that has the same test listed more than once. All I want to do is drop the older testname and keep the testdate column.
Select Distinct TestID, TestDate, TestName
From third.test
I want to keep testdate in the query....guessing I need to put in to a temp table then drop the oldest one somehow by doing a subquery using Select Max....
I want to fetch max of Field2 if duplicate records in Field1 and rest of the values of field1 , below is the sample format.
Field1 Field2 Field3 Field4 32 375 abc-xyz A 32 379 xyz-efg A 55 405 abc-xyz B 55 407 xyz-efg B 132 908 abc-xyz C 132 999 xyz-efg C 152 800 abc-xyz D 152 850 xyz-efg D 155 900 abc-xyz E 156 925 abc-xyz F 157 935 abc-xyz G
With the data example below I am trying to consolidate the duplicate rows by flattening the dealer and billcode, or putting those values in each of the columns instead of creating separate rows...

I need to update a large table, about 55 million rows, without filling the transaction log, in the shortest time as possible. The goal is to alter the table and change the data type for Text column from VARCHAR(7900) to NVARCHAR(MAX).
Since I cannot do it with an ALTER TABLE statement (it would fill up the transaction log) I'm thinking to:
- rename column Text in Text_OLD - add Text column of type NVARCHAR(MAX) - copy values in batches from Text_OLD to Text
The table is defined like:
create table DATATEXT( rID INTEGER NOT NULL, sID INTEGER NOT NULL, pID INTEGER NOT NULL, cID INTEGER NOT NULL, err TINYINT NOT NULL,
[Code] ....
I've thought about a stored procedure doing this but how to copy values in batch from Text_OLD to Text.
The code I would start with (doing just this part) is the following, but maybe there are more efficient ways to do it, or at least there's a better way to select @startSeq in the WHILE loop (avoiding to select a bunch of 100000 sequences and later selecting the max).
declare @startSeq timestamp declare @lastSeq timestamp select @lastSeq = MAX(sequence) from [DATATEXT] where [Text] is null select @startSeq = MIN(Sequence) FROM [DATATEXT] where [Text]is null BEGIN TRANSACTION T1 WHILE @startSeq < @lastSeq
There are 3 columns in the result set - part num, Qty and MO num. Each MO num has part numbers.So there might be same part numbers in MO's. Each part num has qty. So, if I group by part num, I get Qty.
1.There are duplicates of part.num and I want to remove duplicates and add quantities of those duplicates into one single quantity. For example, xxxx is a part num, then xxxx=1,xxxx=3,xxxx=5. I want xxxx=9. I want to sum those. Another question is, each MO has a user. I want to join user and MO num in MO.
Heres the code,
part.num , (woitem.qtytarget/wo.qtytarget) AS woitemqty,
(SELECT LIST(wo.num, ',') FROM wo INNER JOIN moitem ON wo.moitemid = moitem.id WHERE moitem.moid = mo.id) AS wonums FROM mo INNER JOIN moitem ON mo.id = moitem.moid
LEFT JOIN wo ON moitem.id = wo.moitemid
LEFT JOIN woitem ON wo.id = woitem.woid AND woitem.typeid = 10 LEFT JOIN (Select sum(woitem.qtytarget) as labor, woitem.woid, uom.code as uom from woitem JOIN part on woitem.partid = part.id and part.typeid = 21 JOIN uom on woitem.uomid = uom.id group by 2,3) as labor on wo.id = labor.woid LEFT JOIN part ON woitem.partid = part.id
I have a table in which a non-primary key column has a unique index on it. If I am inserting a record into this table with a duplicate column value for the indexed column, then what will be the error number of the error in above scenario? OR How could I find this out?
I have a requirement to implement CDC for 50+ tables to implement incremental data changes warehouse/reporting rather than exporting the whole table data. The largest table is having more than half a billion records.
The warehouse use a daily copy of OLTP db (daily DB refresh). How can I accomplish this. Is there a downside in implementing CDC just for the sake of taking incremental changes on the tables?
Is there any performance impact if we enable CDC on OLTP db?
Can we make use of the CDC tables on the environment we do daily db refresh so that the queries don't hit OLTP database?
What is the best way to implement CDC to take incremental changes for reporting.
hi all, I have created a table in sql server 2005 as follows: table name --> sampletest 1.id -->int ,identity,primary key 2. student_name --> varchar(50),not null 2. active --> bit, default value=1 Using vb.net 2005 , i entered names into sampletest. And when i check the table in the sql server 2005 the names are inserted and the active value is 1. In another page i added a drop down list which bind all the student_name from sampletest and a delete button. Now when i select a name and click the delete button that respective item's active column should be changed to 0. if any one who knows how to do this please help me.. thanks swapna. When i enter names into the student_name it's active state is "true".I do this programmatically using vb.net 2005.
I have one table with two columns, GUID and PID and another table with three columns, GUID, LastName, and FirstName. For each unique PID, I need to find the PID's that have more than one GUID and then match that with their respective FirstName and LastName from the other table.

I'm building a messaging functionality in to my application, I'm able to insert a message into the database and this message then appears inside the other users inbox. The issue I have it when I click on this message to view the conversation I make a call to the following sp as shown here:
@UserId bigint, @SenderId bigint AS BEGIN SET NOCOUNT ON;
[Code] .....
The problem with this is I'm trying to connect to the user photos table to return their profile picture, but for some reason even though I have specified IsProfilePic I get all the photos returned, instead it should be two photos, one for the @UserId and the other for the @SenderId, its equivalent to me doing this:
Select * From [User].[User_Photos] where (UserId = 1 or UserId = 2) and IsProfilePic = 1
In y sql server table has millions of records available. I don't want to drop the tables.
My requirement is I want to change the column order of an existing table. some tables I am able to saving on design window Like Below image.
Even I had generate a script and using that script trying to execute on Management Studio but unable to saving the new column orders. I am getting the Timeout expired error after couple of minutes. How can we save the orders without dropping the table !
When using Change Data Capture on SQL Server 2012 I have researched that you cannot truncate data in a table. Is this also true if one wanted to delete data from the table? Getting a little confused about what DDL statements can be ran against a table with CDC enabled. Does CDC have to be disabled before performing certain DDL statements against a table?
I would like to safeguard the truncation and dropping of certain tables within the dbo schema. Wondering if I could do this with one fail swoop with CDC enabled on those tables. The other option would be to use a DDL trigger to prevent certain DDL statements to be performed.
hello everyone, how to prevent putting same value into the column in the sqldatabase? while inserting value into the table from asp.net page dynamically,i dont want user to insert same data again and again. is there anyway i can make check the column in the database to look for the duplication value. if not then only i want to make it insert. thanks. jack.

Hi all, I have one table in which one column contains duplicate values. My question is how i can use T-SQL so that i can retrive values for all columns in the table which are distinct and retriving the single value from column which contains duplicate values.
INSERT INTO dbo.TestDpln VALUES('1','312','555','1212','212','1212','1') INSERT INTO dbo.TestDpln VALUES('1','312','555','1213','213','1213','1') INSERT INTO dbo.TestDpln VALUES('1','525','555','2212','212','2212','2') INSERT INTO dbo.TestDpln VALUES('1','525','555','2213','213','2213','2')
SELECT DISTINCT SiteIdx, COUNT(*) as "3-Digit Count" FROM dbo.TestDpln GROUP BY SiteIdx, "3-Digit" HAVING COUNT(*) > 1
but it only shows one column and one site I'm not sure how to get the '4 Digit Count' column to show up and the rest of the sites. below are the results I get so far.
I am in process to develop TSql code to identify change in data.
I read about Binary_checksum and hashbyte. Some people say hashbyte is better than binay_checksum as chances of collision are less.
But if we may consider following, chances exist in hashbyte too. My question is what is the best way to compare data to identify change (I can't configure CDC) ?
We have a table with 1 million rows with duplicates in a column which allows nulls.Can we enforce uniqueness for only future inserts by anyway(ignoring the old ones)? Thanks!
I am trying to get people from my table that have closed accounts. However, in my table many people have more than one account. They will have multiple closed accounts and some active accounts. I need to get the people with only closed accounts.
Values in the table
Code: name surname status Closed Number ----------- --------- ----------- ------------- ---------------------------- Jeff Burns closed 2012/01/01 142 Tina Drewmor closed 2008/05/20 546 Jeff Burns active 1900/01/01 354 Kyle Higgin active 1900/01/01 851 Tina Drewmor closed 2009/04/14 154
The query I am using so far is:
Code: select d.name, d.surname, s.status, s.closed, s.number from d d inner join s s on d.number = s.number where s.status = 'closed'
What I need to see in the results
Code: name surname status Closed Number ----------- --------- ----------- ------------ ----------------------------- Tina Drewmor closed 2008/05/20 546 Tina Drewmor closed 2009/04/14 154
