Replacements of substrings in strings

This is not a piece of cake as I thought.

Have to replace few characters with few other characters in the string.

Now, I am using nested Replace:

(Replace(Replace(MyString,'','UE'),'','OE')

This example is simplified, number of replacements is more than eight of them.

Is there any other, more elegant, way to do this in just one command?No, but if you find yourself doing the same REPLACE in several places in your code, you can roll it into a function for ease of programming and clarity.|||Please ealborate a little...first read the sticky at the top of the forum...but my guess is you need to fix a table in one shot...

I would write a view, unload it, then reload the table...

Just a guess though

Repeatable error, with script, with code

Hello

I have spent the last weeks trying to solve this problem but with no
luck at all, I have a piece of code that looks like this

declare@.bestnr int,
@.artnr varchar(25),
@.journalnrrow int,
@.bestlevant decimal,
@.vb_inpris money

set @.bestnr = 33434
set @.artnr = '1441'
set @.journalnrrow = 11
set @.bestlevant = 50
set @.vb_inpris = 10

insert into bpl (bestnr, artnr, jibpjournal, bestlevant, vb_inpris,
bestlevantextqty)
values (@.bestnr, @.artnr, @.journalnrrow, @.bestlevant, @.vb_inpris,
@.bestlevant)

This code works just fine in query analyzer, but in SQL server agent
it does not work it creates an error message about string or bnary
data would be truncated, Simon suggested this has to do with
ansi_warnings being OFF in query analyser and ON when SQL srver agent
makes its connection.

I have scripted my entire DB at
http://donald.fruitsalad.org/microsoft/entiredb.sql

That script creates all the deps and tables and triggers for our DB,
any help would be appreciated, I just don't know where to turn, we
have hired a consultant but that did not help either as he could not
solve the problem.

If anyone know a good sql consultant in sweden that might have a clue
about this, please let us know we are getting pretty desperate.

Regards

Hi Matt,

To begin with: Simon (Hayes?) is correct. The reason that you see this
different behaviour is due to the settings Simon mentioned. These
settings are provided for historic reasons.

Previous versions of SQL Server had the feature of trimming strings
that didn't fit the declared length of a variable or column without
notice. For SQL Server 7.0, Microsoft wanted to certify as compliant
with the SQL-92 standard. One of the things this standard proscribed
was that trying to store a string in a columns with a shorter length
is an error condition. In order to provide backwards compatibility,
Microsoft supplied option that allow users to select the amount of
ANSI compliancy. The behaviour on string truncation is governed by the
ANSI_WARNINGS setting.

Try the following in Query Analyzer to see what I mean:

drop table test
go
create table test (try# int, shorttext varchar(6))
go
set ansi_warnings off
insert into test select 1, convert ( varchar(30) ,
COALESCE (SUser_SName () , 'XX' ) )
go
set ansi_warnings on
insert into test select 2, convert ( varchar(30) ,
COALESCE (SUser_SName () , 'XX' ) )
go
select * from test
go

Boy, am I glad I'm no longer on a dialup connection - almost 100MB!!
When I saw how long the download would take, I assumed you had lots of
inserts embedded in the script, but I now see that it's just the DDL.
You sure make some pretty complex databases... :-|

I killed the osql process that executed your script after more than 30
minutes, as I've already found the cause (though it's absolutely
possible that there are more culprits).

This line is taken from the create table statement for bpl:
[perssign] [varchar] (6) COLLATE Finnish_Swedish_CI_AS NOT NULL ,

This column has a default, specified in the (old and proprietary)
Transact-SQL syntax:

create default DefDbLoginId as convert ( varchar(30) ,
COALESCE (SUser_SName () , 'XX' ) )
GO
(...)
EXEC sp_bindefault N'[dbo].[DefDbLoginId]', N'[bpl].[perssign]'
GO

The default results in a varchar(30) value. You attempt to store this
in a varchar(6) column. That's why the error gets raised if the ANSI
warnings option is set to on.

Some ways to get around this:
a) Change the default DefDbLoginId - replace "varchar(30)" with
"varchar(6)" in the convert function call. (ANSI standards does permit
truncation of strings in explicit conversions).
b) Make sure you always run your code with ANSI warnings set to off.
c) Change the maximum length of bpl.perssign to varchar(30).

(*) Note on ANSI (and other) settings: a default for these settings
can be set per database. This default can be overriden for each
connection. Many tools (like Query Analyzer) will do so - the settings
QA usses for each connection can be found (and changed) via menu
option Query / Currenc Connection Properties and the defaults for new
connection via Tools / Options / Connection Properties. Within the
connection, the setting can be flipped as often as wanted with the SET
command (like I did in the example above).

In Sweden? No, sorry. I only know SQL consultants in the Netherlands.

Best, Hugo

reorder size of secondary data files?

Hello,
I have a database which secondary files are splitted into
4 pieces. Each Piece on a severall harddisk (18GB).
Now i have the following situation:
file1(.ndf)=5GB
file2(.ndf)=11GB
file3(.ndf)=17GB
file4(.ndf)=7GB
Is there a possibility to balance the filesize?
The harddisk for file3 is at the limit and doesn't spend
any performance!!!
10GB for Each file and a balanced growth would be nice!!!
Thanks a lot
CharibertYou can shrink the bigger files so that data from it gets "pushed" over to the smaller file (I
suggest you pre-increase the size of the smaller files before this).
Above is only way I can think of, unless you want to go through unload/import route.

> Charibert|||Hello,
I have noticed that SQL server tries to automatically
balance infill of the files in filegroup.
Recently I've added one file to each filegroup in
my DB but existed files weren't filled completely and
now I see that server insert new data into the new
files only and execution of INDEXDEFRAG is actively
moving data into new files!
So, in your case, it may be useful to increase size of
some files, run some reorganisation work (rebuilding
indexes is the best way), and later shrink files which
will get free space.
