Data Rules Violations
I have a table of 19,000 records with about 225 fields in each record. It is
not an indexed table, just a table of educational transactions. Some how when I go to update the historical table seven (7) records have gotten some bad info in them. I know I can copy the table to another database and look at them one field at a time, but this will take forever. Does anyone know a quick method of finding the seven bad records? Thanks in Advance John Q |

Thanks in Advance John Q It depends how you define bad. If you have a criteria, then you can write a query to ientify those "bad" records. John... Visio MVP |

Hello John,
When a table has 225 fields, it is a certainty that your database tables are misdesigned. This is a substantail problem that needs solved. What constitutes a bad record? You can find the seven bad records with an appropriate query. Steve "John Quinn" wrote in message ... I have a table of 19,000 records with about 225 fields in each record.

It sounds like you have a spreadsheet like Excel instead of a relational database that is the intended purpose of Access. If your data was 'normalized' then it might be easier to find something. -- Build a little, test a little. "John Quinn" wrote: I have a table of 19,000 records with about 225 fields in each record.

What "historical table"? If it truly is historical info only, why are you "updating" it? How do you know that there are 7? Do you know which field(s) contain the bad info? Does "bad" = corrupted, or does "bad" = inaccurate? More info, please...

Hi -
How did you determine that 7 records had 'bad' data? Did MS Access give you an error message on a data import, or did you just happen to notice the bad data? If the 'bad' data is actually in the tables, then it is not likely to be a problem with MS Access - more likely to be a problem with the source of the data. As has been pointed out, 225 fields is a REALLY large table - can you give us an idea of what it contains? It might be that there is a much more efficient way of reaching your goal.

Sorry Staeve;
Every field depends on the previous field. If I designed a table for each scenario, I would have about 200 tables being linked to I do not know how many other tables. Testing applications have become very difficult and are now one of the toughest applications to design. Microsoft consultants were at the Texas headquarters because so many people have had comments like yours. Did could not come up with a better design either. It cost the State of Texas $275,000.00 to do almost exactly what we did. Some applications do not coincide with Microsoft's or IBM rules! Thanks for getting back however!

The legal community for the Department of Education is now requiring a weekly
account of all the students we test and grade. I move the infor to the SQL database in the event of a law suit by the parents. Thanks for getting back! Hope this gives you an understanding of what we face in education. John Q. "Jeff Boyce" wrote: John What "historical table"? If it truly is historical info only, why are you "updating" it?

It is a sequence of information and approvals for each subject, grade,
homework and tests. If a student is taking English then we need to show all scorces given and the relationship to the previous grad or score. With each entry you must always carrt fields of data for who reviewed it, approved it, made suggestions or rejected the educational technique used. There is also a comparison made to grades when the student goes into the next level of education. For example from grade school to middles school, from middle school to junior high and from junior high to college. We even have to know that the student entered college and if that student graduated or not. The designers at Fort Hood, indicated iot was the toughest applications they have ever seen. Microsoft consultants were amazed at what the attorney's in Washington DC want us to keep an accounting of. The bad data message comes from an append query. The tables are suppose to be identical but for some reason this happens once in a while. I eventually find out where the problem is, but it takes so long. Thanks for the interest. John Q.
