SQL Syntax for Access database
This pertains to LV only due to the fact that LV requires a slightly different syntax for SQL statements for use with Access than what you will see in the Access Queries SQL view. For instance, I discovered that if you use a ? for a character placeholder (can be any single character) in Access, you need to use an _ (underscore) for this feature. I also discoverd that you use a % sign instead of an * (asterisk) for any number of characters.
The lat thing I am having trouble with is specifying a range of characters that could be in a certain position in the text field. For instance, if the first character can be only an alpha between A and Z, and the next two characters can be numbers anywhere from 1 to 12, I would use LIKE "[A-Z][1-12]*" In LV, the double quotes are are replaced with single quotes but I cannot figure out what to replace the brackets with.
The brackets do not return a syntax error but also do not return any results that should fit the pattern.
I have tried parenthesis, double quotes, using a TO in place of the dash, etc.
Any input on this is very much appreciated.
Doug
I guess sometimes writing the problem out helps one deduce the answer by taking a closer look at what has been tried and what has not.
So LIKE "[A-Z][1-12]*" in Access will be LIKE ('[A-Z][01-12]%') in LV. I hadn't tried the pecent sign in place of the asterisk using the brackets. Too bad this stuff isn't spelled out in detail somewhere.

Thanks Danubio for the links. The one for the SQL utility may be helpful as I go forward.
Mike, yes I am using the connectivity toolkit. It's what I cut my teeth on and up to this point, has not caused me any issues. I rarely make changes after implementation but if I do, the use of typedef's keeps it pretty painless. A brief read on the doc included in your referenced zip file confirms there are alternate methods to talks to the database tables (I am not a one table programmer). When time permits, I will do some trials and if warranted, will try some of your techniques at some point. Simply not enough time currently.
As I posted intially, I actually solved my problem before there were any replies and included my solution in the first post. Why there is a syntax difference going from LV to an mdb is an unknown to me but it exists nonetheless.
Thanks for the input on this

The syntax for accessing MS SQL db from JSP
Can anybody help me with the syntax for accessing MS SQL db from JSP???

One way of doing this is to use ODBC. Here's an example:

Thin driver for Access Database
Hi Guys,
I want to know the exact thin JBBC driver for access database,
For oracle we have "jdbc:oracle:thin:@host:port:sid" driver, I need the similar type of driver for Access,
Where can I find
Thankslet me be a bit more descriptive..
there's no free, publicly available type 3 or 4 driver for Access.
However, if you want to buy one, take a look at this URL: http://industry.java.sun.com/products/jdbc/drivers .
It'll help you identify third-party vendors who sell what you're looking for...

What is the proper SQL syntax for dates input as variable
Hello,
I am working on an ASP JavaScript page that requests totals
from an Access database for a specific date range. I can write the
SQL statement to query the DB and get the results I need using the
WHERE statement below.
...WHERE LABOR_DATE BETWEEN #7/15/2006# AND #7/18/2006# GROUP
BY [LABOR].[JOB_NUMBER_NAME]
I have another page that I want to pass two variables in
Dreamweaver specifying the date range varBeginDate and varEndDate
and query the database using the date range input by the user.
What is the correct syntax for replacing the actual dates in
the example above with my variable values?Short answer - you can't. There's no automatic link between file paths and mounting servers. There are lots of valid reasons for this (e.g. preventing malicious links from automatically opening files from remote servers), but you can get there in a controlled environment.
You can configure Automounts on any directory. That way whenever any application tries to access a particular path the OS will automatically mount the directory, but it needs to be told in advance which directories (and which servers) to mount.
For example, if you'd configured your iTunes Library to be saved at /mnt/itunes and it's served from afp://mediaserver.your.net/path/to/itunes you would configure an automount to mount the AFP server at /mnt/itunes.
Since its an automount, the OS wouldn't mount the server until some process tried to read /mnt/itunes.
There are several ways of specifying automounts, and for each there are several tutorials online that walk you through the process. Try Mike Bombich's site for a starter. -
Problems with Dynamical SQL Querys on Access Databases!

I am attempting to write a SQL command for a Crystal report that links tables from two different databases, both of them Progress databases.I keep getting syntax errors that the table from the other db (meaning not the one I opened in DB Expert) can't be found. If someone has experience with Progress or otherwise has any ideas it would be greatly appreciated.
I'm not familiar with Progress, but does it have something like MS SQL's OPENQUERY using Linked Servers (which allows you to query a different DB server from the one you're connected to)? If not, you'll probably have to use two different SQL Commands to base the report on, then use Crystal to link the returned data sets. (I'm assuming "a different database" means "a different database server", not a different database on the same server instance...)

Do we need run catbundle.sql file for new databases.
dear all,
i have doubt over execution of catbundle.sql or not?
scenario:
i have insatlled 10gr2 on rhel5 and applied patchset 4 (10.2.0.5) and applied Oracle® Database Patch 10248542 - 10.2.0.5.2 Patch Set Update
after this i have create fresh database.
now,
in Oracle® Database Patch 10248542 - 10.2.0.5.2 Patch Set Update document it has specified in belwo section
3.4 Post Installation Instructions for Databases Created or Upgraded after Installation of PSU 10.2.0.5.2 in the Oracle Home
These instructions are for a database that is created or upgraded after the installation of PSU 10.2.0.5.2.
You must execute the steps in Section 3.3.2, "Loading Modified SQL Files into the Database" for any new database only if it was created by any of the following methods:
Using DBCA (Database Configuration Assistant) to select a sample database (General, Data Warehouse, Transaction Processing)
Using a script that was created by DBCA that creates a database from a sample database
Cloning a database that was created by either of the two preceding methods, and if the steps in Section 3.3.2, "Loading Modified SQL Files into the Database" were not executed after PSU 10.2.0.5.2 was applied
Upgraded databases do not require any post-installation steps.
so do we need to run catbundle here or not.
since i have created fresh database after applying 10.2.0.5 PSU2 why does it required.

Access vs. SQL Server for online database
I have a client who insisted on using Access for his online
database because he wanted to be able to download it quickly and
easily to be able to manipulate data on his end. However, after
importing about 20 thousand records into his existing database,
he's not happy with the speed at which it's now processing searches
- the search criteria and underlying queries are very complicated
to begin with. We had the SQL Server discussion previously, but he
wanted to keep it in Access. So, my question is...how much faster
can SQL Server process data over Microsoft Access? Will the results
be significant enough to justify converting the database to SQL
Server? Would his data process faster if he was on a dedicated
server instead of a shared server? Thanks!If you can get away with using 3 digit zip code areas for
some of your partners, that might cut down on the total number of
records in your database. Also, in addition to indexing, indexing,
indexing, be aware that the "distinct" keyword is a pretty big
resource hog as well. Might be best to stay away from that one.
Not sure if I remember if Access supports stored procedures
or not, but any queries that you can precompile on the database
side will speed things up a bit.
Of course, you could just explain to him that downloading a
20,000 record access file, waiting for it to finish, editing it,
uploading it back to the server, and waiting for it to finish is
not exactly a very effective work flow. You could switch everything
over to MS SQL and then just give him a bound data grid into the
data in CF if he really wants to manipulate the records like that.
But then again, I know how these things go. My
condolences. -

Cannot connect and run query for Access database
Hi,
I have a html file and a servlet file which contains code to connect to a database. I also have a sales database with customer table along with other tables in Access. I have created a DSN in Windows named sales which connects to the sales database. Now, when I am running the html form, the servlet does not run the query "Select * from Customer". It seems it cannot make any connection to the database.
Any help is appreciated. I am very new to JDBC technology. Thanks.

con = DriverManager.getConnection(url);
The username and password aren't needed, so you can just use the above call instead. Perhaps the ODBC is trying to find a user called "" with a password "" and puking on itself, who knows... but you should post whatever exceptions or specific problems you're having that make you think you're not connecting. -

PreparedStatement updt = db.prepareStatement("insert into tablename values (?, ?, ?, ?, ?)");
updt.setInt(1, number);
updt.setInt(2, 1);
updt.setString(3, staffName);
updt.setString(4, description);
updt.setDate(5, today);Oh...
but when I use microsoft access, it didn't seems to work
error is:
SQL data type out of array
the PreparedStatement and it's associate syntax don't work with ODBC? -
Facing permission problem for accessing database
{color:#0000ff}Hello All,
I have just started in this forum. I am very new to j2me and facing problem and I need your help.
I had successfully signed the application and it was working properly on device. Next I added login module in my application where I am accessing a PHP from server which is having MySQL DB connection for usercheck. When I try with unsigned jar it works properly and when I try using signed jar it is showing me wrong username/password. I think it is midlet permission problem.
It would be very nice if someone can tell me what might be the possibilities that it is going wrong.
Thank you.
Regards,
-Anuradha{color}.Signing MIDlet has nothing to do with how data is send over the network. So please be sure that your signed MIDlet is not corrupting your data.
If you are receiving correct username / password at server side, then its server's responsibility to validate it Your MIDlet has posted the parameters right way.
I would suggest you to check following things
1) Check if server is validating the username / password.
2) What response does server sends you back after validating username / password. Check on both ends.
3) Check how your midlet processing the response from the server.
4) Do you get any exceptions?
but I am doing database connection through php which is on server, I hope it is not wrong way of doing it.Doesn't matter what technology is used at server side to connect to the database.
