MS Access To SQL 7 Migration And Programming
Dec 1, 1999Hi-
Can you give me any help/assistance on the development process involved with migration from MS Access to SQL Server 7.
Specifically, I need my current MS Access data migrated to SQL, and then I need two (2) fairly simple forms developed for data input and searching on the web.
The developers I have been speaking too seem to want to buy their Hawaiian condo from this one project...which seems like A LOT OF $$ for the development of an off-the-shelf product that costs $15,000.
Any leads and/or thoughts would be GREATLY APPRECIATED.
THANKS.

VB2008 SQL Database Programming Basics Question
Feb 25, 2008I am writing a program where I will be calculating some values that need to be sent to an SQL Database row by row. I am new to SQL Database programming and I was wondering what I need to include in my program as far as declarations, and data adapter connections in order to accomplish this. Or is it enough to already be connected to my database via a manual data connection? I also need to know some of the basic commands for inserting a new row, and adding data under existing columns, prior to moving on to the next row and repeating the process. If you can point me to a basic example that demonstrates this, including how to properly close out my database, I would appreciate it. If you know of a good VB2008 SQL Database book that covers all the basic & some advanced SQL Database programming, I would be interested in that as well.
For Example:
Row# Name CalcA CalcB CalcC CalcD
1 ? ? ? ? ?
2 ? ? ? ? ?
Etc€¦
Thanks.

Database Access Via COM Objects - V- Database Access Via Stored Procedures
Aug 17, 2000We have been asked to look into using stored procedures with SQL Server 7.0 as a way to speed up a clients site. 99% of all the articles I have read along with all the books all say Stored Procedure should be used whenever possible as opposed to putting the SQL in your ASP script. However one of my colleagues has been speaking to Microsoft and they said that that they were surprised that our client wanted to use Stored Procedures as this was the old method of database access and that now he should really consider using COM objects for data access as itis much faster. Has anyone got any views on this or know of any good aticles regarding this matter ?

Jun 10, 2015I have recently upgraded to SQL2014 on Win2012. The Access front end program works fine.
But, previously created Excel reports with built in MS Queries now fail with the above error for users with MS 2013. The queries still work for users still using MS 2007.Â
I also cannot create any new queries and get the same error message. If I log on as myself on the domain to another PC with 2007 installed it works fine, so I don't think it is anything to do with AD groups or permissions.

RMO Programming In VB.net
Aug 17, 2007Hi,
Currently I am using the BCP functionality to import/export tables between different SQL Server 2005 databases. The process is working ok, but it creates alot of manual work, when 70 or more tables need to be transferred, every week. I am new to RMO development and am interested if the following may be possible.
- I would like to build an interface in VB.net allowing users to select a source database, and select the tables that need to be transferred from the Source DB, to the Destination DB.
-Put in place RMO funtionality to replicate the source database tables into flat files.
-Within the Vb.net app transfer the created flat files into the destination database.
I would greatly appreciate any advice on this, or if there may be a better approach at replacing the BCP functionality.
Thanks,

Cannot Get Access To My Access 2003 Database Tables
Feb 5, 2007 I developed a database with Access 2003 and everything was working good until my tech came in and reformated my hard drive and install a new Ghost image that met our company standards.
Now I cannot go in and make any changes to any of the tables, queries and forms. All of this started when a new Ghost image was installed on my pc.
The message I get when I try to open my database is "You do not have permission to run "tblSwitchboard." I get the same error message when I try to do anything at all on the database.
I am at a loss as to what to do. Please help.

I got this script from the query analyzer templates as a database basic template:
IF EXISTS (SELECT *

WHERE name = N'<database_name, sysname, test_db>')
DROP DATABASE <database_name, sysname, test_db>
GO
CREATE DATABASE <database_name, sysname, test_db>

can someone give me guidance please...
Transact-SQL Programming
Aug 3, 2000I have a table containing almost 700000 records. The table contains the following fields:
table_id, member#, car_eff_dt, car_term_dt, mbr_occur.
A member can occur more than one time and his effective date/termination date are sorted sequentially.
An example would look like this:
table_id member# car_eff_dt car_term_dt mbr_occur
1 12345678901 01/01/1995 12/31/1995 null
2 12345678901 01/01/1996 12/31/1996 null
3 12345678901 01/01/1997 12/31/1997 null
4 10987654321 07/15/1998 02/16/1999 null
5 10987654321 04/01/2000 12/31/9999 null
Using Transact-SQL, is it possible to generate a unique number for each occurance of a particular member#?
table_id member# car_eff_dt car_term_dt mbr_occur
1 12345678901 01/01/1995 12/31/1995 1
2 12345678901 01/01/1996 12/31/1996 2
3 12345678901 01/01/1997 12/31/1997 3
4 10987654321 07/15/1998 02/16/1999 1
5 10987654321 04/01/2000 12/31/9999 2
Currently, I am running the code in an Access/VBA module through an ODBC connection, but I would like to be able to run all my code directly on the server.
Thanks in advance for any help you might be able to provide.

What Programming Language Is Behind SQL?
Dec 9, 2004I am looking into a production geared software called MassGroup. (www.massgroup.com) It says that its FactoryServer builds are on a standardized SQL framework and web architecture for data collection, work order requests, reporting and asset management. My questions are:
1. Is SQL its own programming language? If not what is it?
Answer: After going thru several pages and reading the fine print I discovered they use VB, ASP, COM technology, and Crystal Reports.
2. How powerful do you think this would be at gathering data and does it have the capability of creating a number sequence automatically? (example: 0001; 0002; 0003...)
Any help would be appreciated.
Thank you in advance!!!!!
Help!! Hate Programming Sql
Mar 3, 2008I have just started in Sql 6 months ago. I was an IT major in graduate school and am now in my late 30's (career change). It took me 4 years to finally get what I thought was my dream job. Well, I was promised training which I have yet to receive and bascially went from doing basic queries that I did in class in college to doing advance Sql - stored procs, etc. I completely hate it. I do not know if it is from the lack of training or if it just not for me. I am completely bored out of mind. I am also tired of struggling everyday to complete assignments. The first 2 assignments I received were way out of my league. I was told this by a project mgr who did a similiar assignment and they have years of sql experience and it took her 3 months with assistance to complete it. I have been with the company for almost 6 years. I am not sure if I should just complete my current assignments and ask if they can reassign me to a different IT department, look for a new job or just continue to struggle and pull my hair out. Please give me some feedback as to how you would handle this situation.

VB And SQL Programming Question
Apr 21, 2006I currently have a table with the fields:
- StudentID as an Identity and is the Primary Key field (PK)
- FName as varchar(15)
- LName as varchar(20)
When I use a combo box, I place the information in it as follows:
- LName, FName/StudentID Ex: Rogers, James/4
In order to find our the student I want, I parse the above field for the StudentID.
Question:
How can I display the student's name only and still get to their StudentID?
Would I have to use an array holding/pointing to the StudentID? Or What?
Thanks In Advance.

SQL Programming Question
Jun 21, 2007Not sure if this is right place to ask this. I have a table where I want a single field to show up in separate columns. (wow its hard to describe what I want. Here is an example
Store_Group_Product_Tbl
store, group id, product
Let's say we have these records:
Store 1 - group 1 - hats
Store 1 - group 1 - clothes
Store 1 - group 1 - shoes
Store 1 - group 2 - drink
Store 1 - group 2 - food
I want my select statement to return:
Store 1 - group 1 - hats - clothes - shoes
Store 1 - group 2 - drink - food - NULL
(and in this case I will be selecting on where store = a selected store)
Is there a way to join it back to itself to get the data I want? Or will I have to select everything into an array and then manipulate that array to get everything columned up correctly?

Programming With Null Fields
Apr 9, 2000I am working on Sql Server 7.0 with a group of Visual Basic programmers that have made the following request:
1.They want all decimals/integer fields in the database to default to 0(zero).
Is there an way to do this for all fields instead of on an individual basis?
2.They don't want a null returned on any character string field.
What is the best way to take care of these 2 requests? Thanks in advance.
