Change Column Data In All Tables At Once
Sep 17, 2005
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' " ?
any ideas ? thanks.

I'm using VBE 2008 and in the edit table schema box it doesn't allow reordering the columns. Any solutions?

For our ETL process, we maintain a TransformationList table that has the source view and the destination table. Data is copied from the view into the table (INSERT INTO). I am trying to find column names in the Views that are not column names in the associated Table.
In the below example, want to end up with three records:
 1, View1, Column4
 2, View2, Column4
 2, View2, Column5
I have it almost working, except that there is a table, ChangeColPrefix table, that is used by the ETL process to change some of the view's column name prefixes. Some of the source views have column names with prefixes that do not match the destination table column names. Say view SouthBase has all the column names prefixed with SB - like SBAcct, SBName. And the Destination table of Area District has ADAcct, ADName. There would be a row in the ChangeColPrefix for SouthBase, SB, AD, 1, 2 that would be used by the ETL process to create the INSERT INTO Area District From SouthBase.
I need to use this ChangeColPreifx to find my unmatching columns between my source views and destination tables. With out that table SBAcct and SBName from SouthBase will not appear to match the columns of ADAcct and ADName, but they do match.
I want to end up with these three records as non-matching:
View1, Column4
View2, Column4
View2, Column5
View1 has Salumn2 and View2 has Salumn5, and they must be changed to Column2 and Column5 as per the ChangeColPrefix table before running the Select from INFORMATION_SCHEMA.COLUMNS EXCEPT Select from INFORMATION_SCHEMA.COLUMNS looking for unmatched columns.
/***** Set Up Test Data *****/
-- Create 2 test views
IF EXISTS(SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[View1]'))
DROP VIEW dbo.[View1]
GO
CREATE VIEW View1
AS SELECT '1' AS Column1 , '2' AS Salumn2 , '4' AS Column4;
[Code] ....

Hi.
I have tables (they are empty and there are no constraints) with columns typed as varchar. In a database I want to change the type of all the varchar columns in all the tables from varchar to nvarchar. What's the best way to do it? Can you suggest code?
I know that to get all the relevant columns I would issue a query like this
select *
from information_schema.columns
where data_type = 'varchar'
Then I would use a cursor... And that's exactly what I would not like to do. Is there any other way?
Thanx.

We have enabled Change Data Capture for auditing our table changes in SQL Server 2008. There is a request to NULL out a few columns (for all rows) in a couple CDC tables, due to compliance with a certification. Is there a compelling reason not to modify these tables and to leave the audit trail as-is?

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 two tables:
dtr
dataid........Subtype
data
docid....mimetype
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 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.

Hi All,
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 appreciate your help.
Thanks in advance,
Sinan Topuz

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
[Code] ....

I have Two Database that exist on Two seperate servers. The two database contain same schema and contains tables and columns of same name. Some tables have slight differences in terms of data types or Data type lenght.
For example if a Table on ServerA has a column named - CustomerSale with Varchar (100, Null) and a table on ServerB has a column named CustomerSale with Varchar (60, Null), how can i find if other columns have similar differences in all tables with the same name and columns in the two servers.
I am using SQL Server 2005. And the Two Servers are Linked Servers
What Script can i use to accomplish this task. Thanks

Problem is, the database collation is "SQL_Latin1_General_CP1_CI_AS" and some fields of some tables have the collation "Latin1_General_CI_AS". You know the Problem ... ;-)
As I don't want to change the columns one by one, I want to ask how can I change collation of all column in a table by 1 Transact SQL? Or how can I change the collation of all the tables?
Thanks, ON

I have inherited a SQL Server Database that has three tables related to one another. The DB uses a Access 2013 front end. I know access fairly well, but am not all that competent when it comes to SQL Server. I am using SQL Server Management Studio 12. I need to change the primary key in one of the tables. When I do so, I get the message illustrated below. How can I get around this?
I did find the place where there is a table option of "Prevent Saving changes that require table re-creation". However, there seems to be a lot of comments that indicate it should not be turned off. If I don't turn it off, how can I
make the changes to the table?

Hi,
it has to do with my unfamiliarity with creating users and dbo privileges. I'm trying to grant access to an outside vendor to import their latest version of a database. I set them up with a user account that had db_owner privileges, however when they ran the dts process it copied all the data as new tables rather than overwriting the existing tables and the new tables were all associated with the user is created instead of dbo user. What do I need to do to facilitate this process?

For a uncomplicated example, our database has 10 tables. Each table contains the column COMPANY. I need to change company from 1 to 4, and I don't want to have to update each table individually (because the number of tables is actually closer to 800).
COMPANY being a primary key isn't an issue.
Is there a painless way to update the COMPANY field in all user defined tables?
