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.
View 3 Replies View RelatedI 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.
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

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 tables namely lu_parameter and tbl_param_values. The lu_parameter table consists of param_id and parameter column containing id numbers for the parameter names.
The tbl_param_values table consists of values corresponding to the parameters with the param_id value as the column header.
I want to join these two tables so that in the result query instead of param_id value as column heading, I need to have the parameter value as the column heading.
I have attached the screenshot of the data for reference. I am not that much aware of sql queries.

Hi
I am using one Publisher with many subscribers for Merge replication of a database.
I wanted to change size one column in a table. So I added a dummy column (through Filter column).
Copied data, dropped old column (through Filter column), added new column, copied data, and dropped dummy column.
On subscriber A, replication is OK. On subscriber B, I get the following message.
--------------------
Initializing
Connecting to Publisher 'REPLIC'
Retrieving publication information
Retrieving subscription information
A column was added to or dropped from the replicated table.
The schema script 'exec sp_repladdcolumn '[dbo].[Items]','C1',[NVARCHAR(1000) NULL], '%', 1' could not be propagated to the subscriber.
The schema script 'exec sp_repladdcolumn '[dbo].[Items]','C1',[NVARCHAR(1000) NULL], '%', 1' could not be propagated to the subscriber.
A column was added to or dropped from the replicated table.
--------------------
I made a new snapshot, reintialized subscription with upload, and tried to sychronize again.
But same message.
Question 1. Is there anyway to make replication?
Question 2. If not, can I at least upload data changes before dropping and making new publication?

I have some data that was entered in the DB in ALL CAPS. I would like to reformat all the rows so that it follows the normal "Capitalization". What is the best way to do this? Shoud I create a console application to accomplish this or is there some way to do it natively in sql server 2005.
View 2 Replies View RelatedHello,How do I change the datatype of a column in a CSV file. Preferably in the select statement (apparently Cast, Convert, & Replace functions don't work when selecting from a CSV). I have a page where users upload their CSV files to and then I use SQLBulkCopy to insert all the records into my sql table. The problem is with columns of money data. EX: "$2,000" >> 2000The CSV file interprets the "$2,000" as a string of text. How do I convert it to a decimal so I can insert it into my sql database?
View 4 Replies View RelatedWe have a little app to help us move applications from developent --> stage --> production. It uploads the files, runs the new stored procedures etc.
One of the things it does is create new columns in existing tables. In EM you can create a new column in any position, but ALTER TABLE seems to only add columns to the end of the table. Is there a way in TSQL to create columns in arbitrary positions in the table? Or do I have to recreate the whole table?
I know we could change the data type or width of a table column in SQl 7 database, but I am not certain if this column is a primary key. Can we change a primary key column width? If we can, how about this column as a foreign key in another table? Will it be automatically updated to the same width? Thanks in advance for your input.
View 1 Replies View RelatedThis one is giving me quite a bit more difficulty then I ever imagined it would...
Essentially I would like to use one table to store the change history for multiple tables. I would like to use an update trigger to check which fields have changed in each record, and write a single record for each field that changed containing the table name, field name, previous value and new value to a history table.
I can't seem to find a good way to do this.
I would like to change the output of a column into a hyperlink however I am not sure that is possible without some further post-processing. I am aware I would have to do:
Code:
select
'<a href="' + URL + '" target="_blank" nav="web">' + tbl_ID.ID + '</a>'
from tbl_ID
however this obviously just exports the text
<a href="[URL]" target="_blank" nav="web">[ID]</a>
This would work fine if I was exporting it into some sort of HTML table however this doesn't work with excel for example. Is there a way to make this possible or would I have to create a macro in excel to add the url with the ID separately?
I have a column in the following select startement called displayvalue. Displayvalue is a varchar column. Primary everything entered into this column is numeric, but there are times when NR is entered. In the select query if it sees NR, I would like to have NR changed in the resultset to NULL or blank. NR doesn't come up all of the time, but I have not idea how to do this in the select statment.
Here goes..
