Updating an expiration date Comment from Frank Fish @ 11/30/2014
OK, I found it; I needed to place [] around the field (as you showed in the video)

Updating an expiration date Comment from Frank Fish @ 11/30/2014
Richard, I was updating a expiration date in my (backup)database, and used:
Replace("CACExpiration","12/16/2014","03/16/2015")

The result of the update removed the old date, and left the field blank. Did I miss something? are dates "updated" differently? Thanks FWFII

Find function to find the space Comment from Bruce Reynolds @ 11/25/2014
Couldn't you use the find function to find the space in the FN calculated field in the query instead of SpacePos-1?


Reply from Alex Hedley:

There are usually more than one way to achieve the same goal.

Do you have an example where you've used FIND you can share?

There's the FIND Function that's a member of the Access.Module but it's not well documented from my quick research.

Many To Many Update Queries Comment from Richard W @ 8/26/2014
I did it myself.  No inter!!  I'm "on vacation" (ha).  I had imported both the schools and teachers into separate tables.  I then exported them in to separate Excel spreadsheets with the ID numbers, I matched the names up (with some effort), changed the numbers by hand and reimported them into Access.  No perfect, but I am getting there.  What's more, my wife, for whom this is all being done, SEEMS to be using the not yet complete database successfully.  I don't tackle small problems to begin with. Actually, I have three separate databases in Act! that I am trying to consolidate into one in Access.  I think it will work, but NONE of it deals with products, vendors, etc, so I have to use my imagination to interpret what you teach into my situation!  But I think I can at about the third or fourth time through a lesson.


Reply from Richard Rost:

That's wonderful. Playing around with it like that is the best way to learn... watch my examples and then figure out how to apply them to YOUR project.

Many To Many Update Queries Comment from Richard Wilson @ 8/21/2014
Richard, I have watched all the lessons on Many to Many Relationships, the Relationship Seminar, the Action Queries, etc and cannot find an answer to my problem.  I have a Many to Many situation in which teachers hold faculty positions at several Universities, and a University will have many teachers.  I have all the data which I have imported from Excel Spreadsheets into tables: SchoolT and TeacherT.  Now I need to get it straightened out via a junction table.  Out of about 750 Teachers and 300 schools there are about 100 teachers with at least two schools.  Can you point to the lesson in which you might have covered something that would help in this problem.  I can do it by hand, but that is tedious at best.  Thanks.


Reply from Richard Rost:

This all depends on how you have your data set up. You've got the schools and the teachers in their respective tables, but where do you have listed which teachers belong to which schools? If that's in a spreadsheet somewhere, you may be able to import it and then use an UPDATE QUERY to change the school name, for example, to an ID value, and then use an APPEND QUERY to add all of those to a junction table. Without seeing a sample of your data, I really can't tell. I will say that in most cases like this, you can't easily get away from some manual data entry. Hire an intern. :)

Perhaps you already cover this somewhere but I wou Comment from Alan Lipps @ 8/18/2014
Perhaps you already cover this somewhere but I would like to know how to take column headings from an Excel file and place them in a single Access field.

for Example:

In Excel:
Id     Q1     Q2         Q3
1      5       6         5
2      6       5         6
3      5       5         5

(ID is the foreign key; Q 1-3 values can be any number--in my case between 0 and 9)

to (Access)
ID    Question     Score
1        1           5
1        2           6
1        3           5
2        1           6
2        2           5
2        3           6
3        1           5
3        2           5
3        3           5


Reply from Richard Rost:

You would need to do this with action queries. Set up the table, then you'll need APPEND queries for each of your fields.

SQL to split First and Last name Comment from Alex Hedley @ 11/1/2013
Saw a nice piece of SQL to do this whilst surfing some forums:

SELECT
Left([Names of employees], InStr([Names of employees]," ")) As FirstName,
Mid([Names of employees], InStr([Names of employees]," ")+1) As LastName
FROM Names;

Separate First Last Names Comment from Deon Riley @ 10/13/2013
Hi Richard,

Your teaching makes so easy for me to split bad data and to replace and minipulate data; however, this next scenario frustrates me, which is:

I've inherited and now have to fix a Table with Staff data that looks like this:

ID StaffName      
1  DeonRiley
2  RicardoRosti
3  KarynJones
4  BevCramer
5  StevePlessis
6  JockHobbs
7  MelSmithy
8  PeachesGedore
etc. over 10000 records

As you can see the above bad data the First and Last names are joined into one string with no spaces or any delimeter except, the UCase letter of the surname.

What process would I use to Parse the first and second part of the name into separate FirstName and LastName fields.

Thank you for your help with this Richard.

Kindest regards,

Deon


Reply from Richard Rost:

That's not going to be easy, but it's not impossible. You would have to create a custom function in VBA and loop down the field looking for the first capital letter (either by ASC char value or with a string). Once you have that, you can use the rest of my techniques to split the field. If you can't figure out how to do it, let me know and I can put the function together for you. Probably take me about half an hour.
