I have a query that consists of three fields. This query is then placed in a form. I would like to set the physical length of my fields because one field consists of 4 digit numbers (I want the size of this to be relatively small) and the other two field consist of categories (field that need more space so that the user may see each letter of the category) Please help.
View RepliesWill keeping your field size shorter result in a smaller MDB file?
Or does Access only use as much space as there is real data in its fields.
Way back in the dBASE III days, dBASE would pad all your "real" information with as many spaces as necessary to fill up your field. I suspect that the MDB structure is probably smarter than that.
Another question on the same topic - I believe there is a maximum number of characters in a record (4000?). Can your field sizes add up to more than 4000, as long as the actual data, all combined, never totals 4000...?
Thanks............

View 2 Replies View RelatedI've done some searches on this, and wasn't able to find an answer--just a hint that this isn't possible. So, I'm asking to be sure.
I know there is a limit to field size at 255--but is there ANY way around that?? I'm transferring a file where some fields have a lot of information, usually not more than 255, but what's there HAS to be there.
If there's no way around it, I'll just have to make an overflow field and move them manually. There have been too many changes made to the table already to start from scratch.
Can I just state... for the record.. that 255 is a stupid limit. It's stupid to HAVE a limit.. it's like Gates saying that we'll never need more then 24 or 500k or whatever the number was.
Thanks,

Is there any way of increasing a text field size to above 255?
View 3 Replies View RelatedHi.
I have a main table (with other tables related to it).
It has the 255 max number of fields. (I know... But bear with me.)
ANyway, I need to change some field's size to smaller sizes. But if I try to change them, even 1 at a time, I get the cannot do because I have too many fields defined.
Ideas???

MS documentation states that space is not reserved for unused characters in a text field. Does this mean that there is no storage penaly for having a text field 255 as opposed to 80.
On a more general note are there any tools to help calculate the size of a table?
Im doing a coursework on ms access on School Management System. I have a table 'tblSubject' containing fields: 'Subject ID' and 'Subject Name' . A student has the right only to choose a maximum of 8 subjects, that is , the field 'Subject ID' must have only 8 records/entries. How to do this ???????
View 1 Replies View RelatedHi,
I have searched on this and it says: it doesn't matter as long as it's of type text. It matter if it's long integer..etc. I am not quite sure.
I wonder if default size '50 of fields' of type text occupies that size in memory even though the data in the field is not 50 chars.

View 2 Replies View RelatedI just discovered that field lengths don't influence table size because Access doesn't pad fields.
A text field with length 20 or 255 doesn't impact the size of the table, just the data in the field does.
I did a test to confirm this.
This blew me away.
So now I ask why do we specify field length for text fields?
I have a subform that shows notes entered but if there is more text in the field then you cant see it all. Can I make it so that this field will grow so the whole input is visible or can I make it so when you click on it it opens in a larger window showing all the txt?

Table tTrades

I get an error message when I try to change either of these Code fields from size 10 to 16 characters
Error message - you cannot change the data type of field size. It is part of one or more relationships. Te change the data type of this field, first delete its relationships in the relationships window.
I deleted all relationships in the relationships window. But I still get the same error message.
If I click on relationship window > "All realtionships", Access reproduces all my relationships in the relationship window. Somehow it knows them. I deleted them all again and saved. But I still get the same error message.

I deleted this form ftTrades. But I still get the same error message.

If I have a DB with several tables containing thousands of records, and most of those records only ever need say 8 characters, does anyone know if changing the field size from default 255 chars to 8 chars will actually benefits the the DB?
Potential benefits I'm thinking may occur are reduced filesize and maybe some speed?

View 1 Replies View RelatedFor some reason I cannot enter decimal values without the number rounding up or down. I've already set it to 'Number' and 'double' and have also tried 'Fixed' set to 2 decimal places. Right now the only way it works is if I set it to 'Text'. However I need to do some calculations with these values eventually.
What's strange is I have another table in the same database that is NOT rounding and is working just fine.
I have a form that utilizes a combo box with 2 options: 0 & 0.5. If I select 0.5 on the combo box the field in the table records it as 2. Why doesn't it reflect as 0.5? And how do I fix it?
This is the general info that I have for the field properties:
Field Size - Double
Decimal Places - 1
Default Value - 0
I have created code to import and excel file and create a table from that info. Now I need to confirm that the import has the correct Datatype of Number and Fieldsize of Double for one of the columns.
View 2 Replies View RelatedI have a form that contains a blank text box for each field in a record. Until very recently it functioned correctly for years. Lately data enterers tried to fill a ten character field with five characters (ANNNN format, example X9999). Some records require an entry in this text box, some do not, so their field is left blank. Lately when a new entry is tried in this field, only the first three characters are accepted, blocking character four through ten from being entered. It acts as if the text length for this text box has been changed to three characters, but it is still the correct length in the Properties box.
The system keeps track of clients who have attended a nutrition education class and the form involved is the location the class was taught.
I have a form to input data into a table1. On the form I have a combo box to read from a next table exchange rate to input into the table1. Field in Tablet for the exchange rate is set to Field size double, Format currency, and decimals 6.
I am unable to set the field size on the form to read the 6 decimals. The combo box is set to Currency decimal 6. I tried General Number and it still only shows only one decimal.
