Moving A Poorly Designed Database To SQL

Sep 27, 2001

I have a Access database which has a address field with multiple data sets in it. I am new to writing code and am having trouble finding a example which will help me split these values out into three seperate fields.

Notice how there is no good order in how they are placed.... Some entry's have commas and some don't. Some have periods and some don't.
EX:
[BILL_ADDR3]
AMHERST, WI. 54406
ASHLAND, WI 54806
ASKOV MN 55704

I then need to convert the state to a state code ie:

2 AK
3 AL
4 AR
5 CA
6 CO
7 CT
8 DC
9 DE
10 FL
11 GA
12 HI
13 IA
14 ID
15 IL
16 IN
17 KS
18 KY


Any good sources of information would be greatly appreciated..... Thank You

Working With A Poorly Documented SQL Database.

Feb 6, 2008

One of the primary parts of my job is working with the SQL database of our Enterprise ERP software. One of my primary responsibilities is writing reports based on it's data and since it is not well documented and this is one of my biggest challenges. To top it all off, it's hard to even use their reports to learn the links between tables as the reports run completely in Visual Foxpro.

Is there reasonably priced software that will analyze the database for me and make it easier for me to figure out the relationships between certain tables and such?

TIA,

Dave

Transaction Log Full Due To Poorly Configured SQL Database

Dec 23, 2005

Good evening all,

I am new to Microsoft SQL and have been dumped right into the deep end with an anchor around my ankles.

The problem I am experiencing is about 6 months back a guy setup a Microsoft SQL server at my client. He then took his bags and left. Then a developer developed an application which uses a database on this sql server. Everything worked well for around 4 months.

Yesterday IBM Director notified me that I am running dangerously low on disk space on the server. By the time I came in to work this morning I had 12mb free disk space. The evil thing here is the transaction log for the downtime database. It has grown to over 60gb, all because the correct measures were not implemented to prevent this.

The problem that is occuring is no one can do anything on the database now due to the lack of free space. I have tried reading the sql books online but due to my lack of sql experience and knowledge I am stuck.

Can someone please help me? What I would like to do is pull my transaction log down to an acceptable size.

I was thinking of creating a new database and then importing all the data from the current database and then just deleting the current database however am slightly concerned that this may result in some data being lost.

Thanks in advance,

Richard

I Need To Generate The Query To Build A Database I've Designed. Please Help..

Apr 3, 2007

I've registered with GoDaddy for my site. I've used Visual Web Dev 2005 with SQL Server Mgmt Express 2005 to create my database etc. Now with GoDaddy, I need to "recreate" the database on their server again, but I don't want to go throug the whole process again. I just want to use their query editor to generate the database online.GoDaddy mentions a "personal-sql" file that SQL Server 2000 generates, but I can't find anything like that with what I have. Thanks.

Poorly Chosen Query Plan

Oct 12, 2000

I'm running the same query on two computers but getting a different query plan. On one of the servers, the query returns in 10 seconds, on the other server it takes over a minute. What the heck!

1. same hardware configuration on both computers
2. same user databases on both computers
3. same NT setup on both computers
4. same software installed on both computers

I can only imagine that MSSQL7 was setup differently and the query optimizer is making a stupid choice. I've compared numerous SQL server options and they are both the same.

1. sp_configure (same on both computers)
2. properties sheet on each server from enterprise manager (same on both computers)


any ideas???

Trouble With Query For Poorly Normalized Db

Aug 21, 2007

I'm working with a database that is poorly normalized and am doing my best to increase the speed of our queries (changing the database itself is not an option right now). Any help with the following situation would be very much appreciated.

There are two tables involved, described below.

DataTable:




Code Snippet

CodeA char(4),
CodeB char(4),
CodeC char(2),
ColA float,
ColB float,
ColC float,
...
ColZ float

NameTable:




Code Snippet

Abbr char(2),
FullName varchar(50)

In the DataTable, the columns named ColA, ColB, ColC, etc., are described in the NameTable where Abbr would be A, B, C, etc., and FullName would be a "nice" text version describing what's stored in that column. For instance, a record in the NameTable might include Abbr = 'A' and FullName = 'Computer Science', and that means that ColA in the DataTable refers to 'ComputerScience'.

The table I'm trying to optimize the creation of in our ASP.NET application needs to have column headings that could be retrieved like this:
SELECT DISTINCT CodeB, CodeC FROM DataTable WHERE CodeA = @CodeA
(Note that CodeC is really just a different representation of CodeB--think 4-digit year vs. 2-digit year--for any given CodeA.)

The row headings for the table could be retrieved like this:
SELECT FullName FROM NameTable

The cells of the table at any given intersection of a row heading and a column heading can be retrieved like this:
SELECT Col? FROM DataTable WHERE CodeA = @CodeA AND CodeB = @CodeB (this selects a single value)
Where the ? of Col? is determined by the Abbr version of FullName shown in the row heading, and @CodeB is determined by CodeB from the column heading.

Right now this table is generated using a lot of loops in the code of the page that require it to query the database for nearly every cell in the table. Even with this poor database design, there has to be a better way than that. I'm hoping there is a way to create a stored procedure that uses temporary tables and joins, or views, or something like that to create the table on the SQL Server and just send the data to the ASP.NET page in a form that can be directly databound to a GridView.

Thanks in advance for any help!

Relationships Correctly Designed?

Feb 26, 2008

I am new to SQL Server 2005. I have tried to be a good student and learn on my own about designing the database. However, I am facing a blockage of getting data into the database. I want to verify I have setup the relationships correctly. Here is the tables.

1. A Manufacture has an Address.
2. A Manufacturer has one or more Distribution Points.
3. A Distribution Point has an Address.

The Manufacturer --> Address is a one-to-one relationship.
The Distribution Point --> Address is a one-to-one relationship.
The Manufacturer --> Distribution Point is a one-to-many relationship.

The manufacturer table has a FK to the address id (PK).
The distribution table has a FK to the address id (PK).
The distribution table has a FK to the Manufacturer id (PK).
Address has several other FK, but not used in this scenario.

The INSERT and UPDATE Specification for the Delete Rule and Update Rule is set to "No Action" for the Manufacturer and Address tables. In the Distribution Point table, the relationship for the update rule involving the relationship with the Address and Manufacturer tables is set to CASCADE. What this tells me is SQL Server 2005 will update the table should changes occur in Address and Manufacturer table.

Is there anything else I can check to be sure the issue I am facing is NOT the deisgn of the database?

Thanks for taking the time to read my post.

Who's The Idiot That Designed The File Destination?

Jan 23, 2007

It's funny:

Everyone thinks that CSVs are awesome to transport data. I mean after all, SSIS defaults to Comma Delimited files. Even Excel defaults to it. Microsoft is supposed to be our leader! They should get this right. And get the terminology correct too. How many people describe the file as comma separated? It's delimited! Even SQL server calls it delimited by the "delimited" drop down.

CSVs suck and i will tell you why:

When you transport any text field (especially Address) it has the possibility of containing a comma. This causes data to be parsed into the wrong fields. Why in God's grace would you EVER get in the habit of choosing a delimiter that SOMETIMES doesn't work?

I'll tell you a little short story:

I have been waiting (at work) for like a month for a guy to export data and give me this file. Well today i finally got that file. He was in a hurry and used the Defaults to export this file. I don't blame him for being in a hurry and using the defaults. Well the defaults made the import NOT work because the data parsed into the wrong columns. Comma delimited would work if there was a text qualifier. But the default is comma delimited and NO text qualifier. What idiot thought that would be good. Or it was the separation of duties that eff'd this one up? Who knows?

Fix your products!

That's my .02

Querying A Really Badly Designed Table

Mar 28, 2006

I am working on an application with a number of tables (which I can't
change) that have data of the form a1, b1, c1... a2, b2, c2...a3, b3,
c3... The tables contain 5 to 10 sets of data in each row.



I want to create a stored procedure to return a cursor with a row for
each set of data for a row of the table. I know I can use unions:



select a1 as a, b1 as b , c1 as c... from sometable where pk=@pk

union

select a2, b2, c2... from sometable where pk=@pk

union

select a3...



Is there a way that is more efficient (eliminates requerying the table and all the unions)?

How To Collapsible A Column When The Report Was Designed In Table Mode?

Jun 30, 2006

Hi folks, I'm trying to collapse a column on a report that's designed in table mode. I was trying to mimick what happens in a matrix where you have a column that has a '+' in it that makes toggles the visibility of a column to its immediate right (The reason I'm not using Matrix mode is I continually get "out of memory" errors on the report I'm generating.).

When I select the column and mark visible to 'false' in the properties, it of course asks me for a TextBox. My problem is that I am unable to find a scenario where the textbox is "in the proper group". Is this something that's supported, and if so, I'd appreciate some pointers to lead me in the right direction.

Thanks.

How To Show SQL Server Data Validation Error Messages In The VB 2005 Designed Interface ???

Apr 27, 2008

I'm developing a database-driven program using SQL server 2000 and Visual Basic 2005.

Most of the guys say professional programming is doing the validation stuff (such as the constraints and data integrity stuff like" [0-9][1] " and the use of LIKE IN keywords etc.) in the databse itself.

say i did the data validation contraints in SQL server itself. and now i connect the database with the interface made in 2005. and say a person enters some invalid data through the interface. but the error messages are generated by SQL server. how am i to display the SQL server generated error messages in the VB made interface??

Hi
I want to transfer a database from one PC to another. (Both running SQL Server 2005 express)
I have copied the files (SQL Server Database Primary Data File and SQL Server Database Transaction Log File) from the C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData folder of the source PC to the destination PC (Same folder).
I was under the impression that using Microsoft SQL Server 2005 - SQL Server Management Studio Express these files would be picked up and could be used, do I infact need to do something to attach the files/database so that they will appear in SQL Server management?

Moving A Database

Nov 14, 2007

I have two computers, both with SQL Express 2005 and SQL Server Management Studio Express. I created a database on one computer, and need to copy it to the other computer. I'd like to do it all through the Management Studio interface, without using SQL commands, since I only need to do this manually.

I detached the two files, copied them to the second computer, and tried to attach them. This is generating lots of messages about not having the necessary permissions of various sorts. I think the main problem is that I don't know how to set up the database's users in a way that allows the second computer to attach the database.

I've tried Windows authentication, using a Windows user that has the same name and password on both computers, and I've defined that Windows user as a user within the database. I've connected to SQL when logged in as that user.
I've tried SQL authentication also, defining the same SQL user within both SQL Servers, as db_owner. But when I try to attach the database, I see no place to specify the user that I intend it to use, and it still fails. If I connect to SQL as that user, then SQL doesn't have permission to look at the file system to find the MDF file.

I'd appreciate the help in learning how to do this with both Windows authentication and SQL authentication, via the Management Studio's GUI. Most of the documentation I've seen covers how to do it by using SQL language commands, and I'd like to avoid that.

Moving Database Roles

I also need to copy over the user or database access information from one box to another. I tried to use dts but it only copied over the users and the database roles but did not copy over the Database user properties which allows the user access and places the user into security groups.

Any help would be appreciated.

Moving A Database To A New Server

Jul 15, 1998

Hi,
I have a database that resides on a server that`s become too old. It spans
2 devices that sit on 2 different drive letters - D: and E:.
I bought a new server, installed and configured NT4.0 and SQL6.5.
Initially I restored the database to the new server from a dump .It worked
fine, however all the login information was lost. Then I tried partitioning
the new server the same way as the old one and copying all the DAT files
over. Thus I was hoping to retain the information contained in the MASTER.DAT,
drop the database, repartition to create 1 physical drivewith 1 database device,
and restore from a dump to it.
After copying the DATs, though, SQL Server would not start.
Help Please!
