Queries :: Hexadecimal String To Binary
Sep 24, 2013
I have a text column with hexadecimal strings like "4E1B0A65FE3299FE", ie. of length 16.I'm doing an ALTER COLUMN query to convert the column to varbinary, but Access is doing conversion by ASCII, which results in a varbinary field of size 32, I think this is because the text column is in Unicode.
SQL Server has something called "styles" which are used with CONVERT.where you can choose to convert by two characters at a time 2:1..How do I do the same in an Access query? CONVERT/CAST are no supported.

I am looking for some help, I have a access database that is interfacing to a sql storage.
The problem I am having, is I have a Image that is containing archives for emails, however I have been yet to figure out hor to read that text stored in the image.
So far I have been able to come up with the data being stored in binary, but am unable to read it in a access form.
Make sence? Hope so.
Through SQL, I am able to run a query to read the data:
SELECT CONVERT(varchar(8000),CAST (body AS binary(8000) )) from arc_bodies
However I would like this text to be read through a form in access, and am unable to figure out how... Please help if possible, would be greatly appreciated.

I am trying to store binary values (as decimal long integers) and then use bitwise comparisons to update the values. MS help suggest that the standard logical operators (And or etc) can do bitwise comparison as opposed to comparing boolean logical values for expressions; but I have found no way of making this work.
Is this possible? Any ideas. Doing it mechanically, by splitting the decimal into the relevant parts for any bit is very tedious!

Hi
I have a problem in binary type in access
I have some values that are between 1 to 32 byte
I want to specify the type of my field to something like "varbinary" such as SQL server but I have not this type
actually I used OLE object type but it doesn't like it.
for example when I use:
insert into t_t1(i,j) values(1,23)
while j's type is OLE object,
the row is inserted but I can not see the value of j column and I can not select on j column too for example
select * from t_t1 where j=23
has no result.
furthermore, I want to use hex values but I can not do it.
when I use
insert into t_t1(i,j) values(1,0xAD)
I got an error that says the type is mismatched
I know it may shows I expect unreasonably from access but please help me to find the solution
thanks for your attention
Best regard

Hi there,
I have a simple bit of VBcode in my database which reads the password a user enters and 'encrypts' it for storing in the user table. It's more obfuscation than encryption to be honest, and I feel limited by the 'text' data type assigned to the password field.
At the moment it works by taking the password entered, and converting the whole lot into a byte array, then for each 'character' in the array, changing its binary value. At the moment it's then converted back into a string and dumped into the 'password' field, as garbage characters. But they are still characters, and if I go out of range of the character set it results in horrible errors :D.
I feel I may be missing the blindingly obvious and could just not convert it back to string, and write the binary into a text field instead, but I'm not sure how I'd get intelligible data back.
The reason it's not exactly encryption is because the key is the same for all characters on all passwords (I just multiply the binary value by 2!) what I want is to have a key as well, stored in another field alongside, but again can't implement this due to character-set range issues.
So my question is - is there a 'raw' data field hidden somewhere amongst the features of microsoft access, or should I be thinking about just storing the numbers themselves? For the moment I'll investigate the latter, but I'll appreciate any help! Thanks :)

This the first time I post in this forum and I tried looking for an answer to my question before posting, so I apologize if my question has been answered previously.
Is it possible to determine, in Access 2000, the data type in a Make-Table query of a new column with null value so that it does not default to binary.
Here is my sample sql:
SELECT tblAddressBook.Name, Null AS Email INTO tblTestTable
FROM tblAddressBook;
The output is tblTestTable with two columns: Name and Email. The data type of column Email defaults to Binary. How do I make it default to Text.
Thank you.

I am looking for a function that will allow me to encrypt/decrypt single image files as and when required. I have built my own simple one to encrypt a string that will be stored in a filename as all the ones I found created unusable filenames.
However I don't know where to start with the image file encryption.
(Any better way to encrypt a string that can be used in a file name that would be great too. My method is a bit basic).

I am working on a project that requires data transfer using TCPIP sockets. I am using a 3rd party Library (Ostrosoft) that handles the wsock32.dll api calls.
The project calls for the creation of a header that logs into a user account.
The first part of the header is a marker, with a value of 4,275,878,552. It is to be supplied in a Binary format of length 4.
My quesion is "How do I create this marker".
What I have tried so far is a string variable - strMarker thus:
strMarker = ChrB(&HFE) & ChrB(&HDC) & ChrB(&HBA) & ChrB(&H98)
Using the ChrB function to convert the Hex version of that number (FEDCBA98)

I have a text field in a Table and on a Query called "Notes" In that field that has data like below:
[04/02/2015:BD] Project is to be assessed by Solutions Planning
[03/27/2015:BD] Project prioritized
[03/14/15:BR] Entered to system
Im trying to find a way to pull just the most recent line of text, in this case
[04/02/2015:BD] Project is to be assessed by Solutions Planning
into the field next to "Notes" or wherever - an empty field in the query. I searched around, found some stuff and I was thinking of having the code look at the first "[" and count the length to the next "[" and pull out whats in between. Looks like the bracket causes issues in the module.

How to reference current row in SQL string? I have a qst while using RowSource. I have 3 tables:
[1] CITY
col: _value _name
[2] STREET
col: _city _value _name
[3] ADDRESS
cal: city street
The problem ocurred when i designed ADDRESS table:
The RowSource of [city] is "SELECT _name, _value FROM CITY".
And I set the binding-column as 2, so that _name can be displayed and the real value is _value(integer).
But here comes the trouble: how can i set the RowSource of [street]?
The _value of STREET table depends on _city, and _city is _value in CITY table.
E.g. _name of STREET is "Wall Street" when (_city,_value) = (1,1),
But "Lincoln Avenue" when (_city,_value) = (2,1)
I want to use "SELECT _name, _value FROM STREET WHERE _city=CurrentRow.city" as RowSource, but what can replace the "CurrentRow"?

I have a criteria in a parameter query that asks the user to enter a Subsystem number (such as 4596-666-001).
The source data for my database has Systems (e.g, 4596-666) and each system has several Subsystems associated with it (e.g, 4596-666-001, 4596-666-002, etc). The System and Subsystem numbers are stored in the same column of the source data spreadsheet, and hence the same field in my database.
The source data is structured in such a way that Systems and Subsystems have different information. I would like to set up a query that shows the System information as well as the Subsystem information.
For example, if the user enters 4596-666-001 into the parameter dialog box the query returns all the information for 4596-666-001 and 4596-666 (but NOT any other Subsystem).
As a work around I have set up an OR situation where the user first enters the Subsystem number and then another parameter query dialog opens and they enter the System number. This works but is not as nice as simply entering the Subsystem number and having all information returned.
Is there a way to set up my query so the when 4596-666-001 is entered an OR is generated using the first 8 characters of the Subsystem number?

I have a field called PropertyID which stores a unique 13 digit number, the 10th digit is always a 3. I want to remove the 3 to leave a 12 digit number.
I've tried running an Update query using Replace([PropertyID],"3","",10,1) but no joy, what am I doing wrong?

I am trying to extract the first instance of 3 numbers from a string using an update query to update another field in the same table(Master Equipment) titled "Code". the field is called "Equipment". the strings vary in length as well as the location of the 3 numbers needed, but I have examples of all possible locations the 3 number series could be located below. As you will notice, some fields do not contain 3 numbers together, for these I don't want to return a value.

Here are the 2 tables that I am working with:
Account
Account
0041980041
0051670051
0052330052
0053490053
Conversion
Account Conversion
0041 10000151
0051 10000152
0052 10000153
0053 100001524
I need to update the Account table using the Conversion table by replacing the first 4 digits in the Account table with the Conversion value. For example, the first record should be updated from 0041980041 to 10000151980041.

Do access VBA implements parameters passed to query strings in all following parameters?I've been working in ASP.NET/Razor C# and this would be an example of how it would be done:
Code:
db.Query("INSERT INTO threads (name, date_of_creation, user_id, area_id, user_group_id)" +
" VALUES(@0, @1, @2, @3, @4)",
Request["txtThreadTitle"],
DateTime.Now,

I'm familiar with writing a replace query to replace characters or strings but what I'm trying to do this time is a bit unique to me. I have a string of numbers that will either be 8 or 9 digits in length. The first 1 or 2 digits will be the State code (1-50 hence the discrepancy in number of total digits), then a 2 digit agency code, then the last 5 digits are a producer code. What I need to do is change the 2 digits for the agency part both to 0. So basically characters 6 and 7 if you're counting from the right. To me it feels like I'm trying to do it backwards so I'm having a hard time writing it.

I have a weight field that I've been populating with the weight and the unit of measure. I want to seperate those into 2 different fields. I've created a new field called UnitofMeasure and now I need to go back and remove all the instances of 'oz' and 'lbs' from the first field.
Is this possible with SQL?

In my query I want to extract the last 10 characters of a string in a column which represent a date in the format DD.MM.YY and then convert these to a real date format to be available for further processing.
My query looks like this:
SELECT Angebotskopf.[Laufende Nummer], Angebotskopf.Angebotsnummer, Angebotskopf.Angebotsdatum, Angebotskopf.Anfragedatum, Angebotskopf.Kunde, Angebotskopf.Ansprechpartner, Angebotskopf.Telefonnummer, Angebotskopf.Faxnummer, Angebotskopf.Projekt, Angebotskopf.Preis, CONVERT(varchar(10), RIGHT(Angebotskopf.Projekt, 8),104) AS TestAngebot
FROM Angebotskopf;
But Access gives an error message "unknown function 'CONVERT'"
The "RIGHT" functions works but the resulting column is not being recognized as a date, it is a only a string and therefore useless for processing of any date related calculation.
