Change Data Type In Many Tables In One Go

May 14, 2008



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.

Change Data Type Of Variable

Oct 3, 2007



Is there anyway to change the data type of a variable while in an expression?
My problem is I am trying to compare a variable w/ a string data type to a variable w/ an object data type. I would change the data type of the variable from object to string but if I do that my sql task fails when it tries to write a value to that variable. The variable w/ the object data type is the result of an openquery sql stmnt. So I guess there are two ways around my problem.

1. Change data type of variable while in an expression..ie flow constriant
or
2. Change data type of vraiable from object to string and still get the openquery result to work.

Any help???
Thanks !!

What Is The Best Practice To Change A Column's Data Type In A Very Big Table?

Dec 11, 2007



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

Update On Large Table - Change Data Type For Text Column

Dec 10, 2014

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] ....

Archiving Data From Some Tables - Timestamp Data Type?

Aug 21, 2015

I'm working on archiving data from some tables. I've duplicated the data structure, with the exception of not including the IDENTITY specifier on INT columns, so that the archive table will keep the value that was generated in the original table. This is all going well, until I tried to copy the data over where the column is specified as a timestamp data type. I've looked this up and found a couple of things. First, documentation for SQL 2000 says,

Timestamp is a data type that exposes automatically generated binary numbers, which are guaranteed to be unique within a database. Timestamp is used typically as a mechanism for version-stamping table rows. The storage size is 8 bytes.

And then documentation for the soon to be released SQL 2016 on the rowversion data type says,

The timestamp syntax is deprecated. This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

and

Is a data type that exposes automatically generated, unique binary numbers within a database. rowversion is generally used as a mechanism for version-stamping table rows. The storage size is 8 bytes. The rowversion data type is just an incrementing number and does not preserve a date or a time.

OK, I've read the descriptions, but I don't get it. Why have a timestamp/rowversion data type?

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.

Need To Alter Data Type On All Tables..

Jul 17, 2003

I need to alter datatypes from
numeric(18,0) to 'int' type across all the tables in the database of about 200 tables. Nearly 200 PK/FKs will be affected with this change..How can I do this with a script? Can anyone help witha script which drops all the constraints/indexs etc and then alters the datatype before re-creating the constraints/indexs..?

P.s. No rounding problem is expected as data is already in whole numbers.

Thanks,
Di.

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.

Changing Data Type To The Fields Of My Tables.

Nov 21, 2006

Hello.

i have a database with 300 tables. All the data types of the fields of my tables are custom. Ex. IFGint:int and stuff like that.

I want to know how can i through a stored procedure, change in batch mode all the fields of my tables. I don't want to modify by hand everytable. It's a lot of work and i think that maybe there might be a way for this programatically.

Using Inserted / Deleted Tables With Text / NText / Image Data Type

Oct 6, 2004

Hi folks,

Table:

a int,
b int,
c int,
d text

I need to change my AFTER - Trigger from this (example!):

select * into #ins from inserted

to something like

select *(without Text / nText / image -columns) into #ins from inserted.

So I tried to build a string like this: (using INFORMATIONSCHEMES)

select @sql = 'select a,b,c into #ins from inserted'
exec(@sql)

a,b,c are not of Text, nText or Image datatype.

After executing the trigger, I get an error, that inserted is unknown.

Does anyone know how to solve this ?

Thx.

datetime data type resulted in an out-of-range datetime value.

Converting A Data Type Double To A Type Float Using A Data Adapter &&amp; SSCE 3.5

Feb 13, 2008

Hi,

I can populate a dataTable with type double (C#) of say '1055.01' however when I save these to the CE3.5 database using a float(CE3.5) I lose the decimal portion. The 'offending' code is:


this.court0TableAdapter1.Update(this.mycourtsDataSet1.Court0);

this.mycourtsDataSet1.AcceptChanges();

this.court0TableAdapter1.Fill(this.mycourtsDataSet1.Court0);


This did not happen with VS2005/CE3.01.

I have tried changing all references to decimal (or money in CE3.5) without luck.

I'm beginning to think that string may be the way to go!!!!!!!

Can someone shed some light on my problem.

Thanks,

Later:

It's necessary to update the datatable adapter as the 3.01 and 3.5 CE are not compatible.
