Tables :: Performance Analyzer - Change Data Type To Long Integer
Dec 22, 2012
When I run the analyzer on all object types it recommends to change the data type for field "zip" (zip code) to "long integer to:
"benefit that table and potentially other objects in my database"
The field type is currently set to text, And I have the same setting for the same field in a separate table, yet it does not come up with a recommendation for that table.
Additionally, I don't seem to have the option "long integer" for the field data type???
Have a few questions after I ran the Access performance analyzer. Now these ideas are they good or just some generic recommendations. Dont know if I should take care of all these or not?
Anyone know if I should do all these things and about how I should do it?
I have encountered an issue when I was inserting a string (with newlines about 176 characters) into access table. This field in access has the data type TEXT and it was truncated after the insertion. It is strange because I have three other fields with the same format and no truncation at all. May I know what could be the reason and how/what is the recommend data type for storing long text?
I have two tables(see below). I want to set up a query, link these 2 tables together. I set a one-to-one relationship between Client ID in two table. But got error message :"Type mismatch in expression".
I tried to change Client ID data type from "Text" to "Number", then Access deleted some data under Client ID in Order table.How can I make this work, but not having to re-type in all data?
Client Table:
Client ID(Autonumber) Client Name (Text) Client Address (Text)
Order Table:
Order ID(Autonumber) Client ID(Short Text) Unit Order(Number) Unit Price
So I have decided that I want my ID's to be AutoNumbers, but at the moment they are currently set as Numbers. I have already inserted data, to test, which has been deleted, however I am now unable to change the ID field back to AutoNumber.
How can I duplicate the tables so that this field can be changed again?
I have like 10 tables with heaps of feild, so remaking them will take long, but I know there is a way using queries, I am just not sure how...
I have an autonumber field set up as long integer. The field just reached the value of 32670 and I get the overflow message. I thought a long integer could be much bigger than that before running into that problem.
I got around it by re-creating the field and starting from 1, but would rather know why it's doing it so I don't have users without their system.
I'm having problems Using Dcount function, when I use it with a text field like the following it works fine: (but using a Surname as a criteria can have problems.... I've people with the same surname in my database...)
times = DCount("[Surname]", "Booktoscore", "[Surname] = Forms!Teachers!Surname.value")
But, If I try to use it with a number, then it doesn't work, the problem seems to be with the criteria.... Because Access don't show me any msgbox with errors....
times = DCount("[IdCandidate]", "Booktoscore", "[IdCandidate] = Forms!Teachers!IdCandidate.Value")
I have a table with about 300,000 records. About ten fairly small fields per record. I am trying to change the length of a text field from 25 to 40 characters, and I get the error message, 'MS Access can't change the data type. There isn't enough disk space or memory'.
I have never seen this message before. I have about 64 Gig of free disk space. What can I do?
I am a pretty novice user currently playing around with Access 2013 using Office 365.
I used to love the old style Memo field where people cut put in carriage returns to split up data. I am wondering if this function has been removed with this LONG TEXT FIELD or is there a way around it.
I like it because I tend to use it as a tracking field and like the newest "comments" at the top separated by a Carriage Return...
Is it possible to run a SQL command to update a field within a table with random numbers?
More specifically - random long integers linking back to an ID (autonumber) field in another table?
Background to this is, I have multiple static data tables related to each other by long integer identifiers (autonumbers)
The structure is fine but I haven't been provided with the actual data yet - but for development purposes, I need to work on other functionality which requires that this data be present.
So I want to fill my table with dummy data such that I can go off and work on the remaining functionality, but then just go back and clear it all out once I get the actual data.
I have one 'main' static table, which links back to other tables, which I have already populated with dummy static (i.e. company names, locations etc) Now I want to go into my main table and populate those fields in each record with a random ID. I don't mind doing this field-by-field (there's only a handful) but I've a lot of records in there (~1000) so I'd rather not do this record-by-record.
I have a table with a field with names set to text data type and i want to change it to number data type but when i do it in design view the data get lost. I want to know if there is a way to convert the data in the field as number type and keep the data in the field.
I have being playing with ms access but I really don't know much about it or databases in general.I have created a very simple database to gather twitter following/followers data for research purposes.One table (table01) has a field for the "boss" user (=the user who I gather data for), another field for "client" (=bosses followers or friends).Both fields are numeric and contain the users id's.In order to distinguish if the link is follower or friend there is a third field, called type which can be either 1 (=follower) or 2 (=friend).So the data would look like this:
boss - client - type 12345, 67890, 1 12345, 54321, 2
If user with user id 12345 had a follower (type 1) with user id 67890 and a friend with user id 54321...In order to avoid getting duplicate rows I also added a unique identifier which is of the form boss_id-user_id-type.So the above row looks like this:
That works just fine.For several reasons I also needed data of the form source - target.So I also made another table (table02) of this form.
67890, 12345 12345, 54321 ...
In table 2 you don't need the "type" field since the position of the user id shows the type of relationship.Still, you need a unique identifier in order to avoid duplicates, so I added on with the form: source_id-client_id..So table02 lookes like this
Both tables also have a date/time stamp for each line.As you can see, table01, having also a type field is bigger than table02.The problem is when I try to append data, exactly the same data in both tables.Appending data to table01 is ok, while appending data to table02 (which is smaller, having one less field) takes a really long time, maybe 10 times as long as appending data to table01.To make sure that no query's are causing the problem I have tried first creating temporary tables with the data to be appended, no duplicates, nothing that would cause the database to make extra calculations and used a simple update query with no filters to append data.Still I get the same result, table02 takes a very long time to finish while table01 finishes in no time.
I'm using Access 2002 and need to increase some field sizes, some by increasing the maximum number of characters and others by changing from Text to Memo. When I try to do this I get the message "Microsoft Access cannot change the data type. There isn't enough disk space or memory"
I have two 320GB hard drives and 4GB of RAM and the Access file is a mere 280MB. Can anyone please explain the problem and tell me how to achieve my objective?
Hi, I am trying to import an excel spreadsheet into Access2000 using the import wizard. I choose my XLS file, I say whether or not the first row contains headings, (no is the anwser). Then I want to change some of the fields to data type of memo from text, but all I can see if Field 1 and data type option is blanked out. If I click or double click on another field it doesn't change. so I cannot change the datatype of a field.. do you know why, and how I can fix this ?
The reason I want to do this is one of the rows in excel has 300 characters, and the text field in access only allows 255.
my teacher asked me to do Access homework to change data type from Text to Boolean. Data in "Owned car" field show as Y or N 17178 so I click on Design View and change datatype of this field from "Text" to "Yes/No" , than when I saved it show a message 17179 When I back to Datasheet view, all data in "Owned car" field change to be "No".
How can I change data type to be Boolean type without deleting my original data??? I want them to show the same as Y or N.
I'm a bit of a newbie, so lets just get that out of the way....
I have a field in a table that was originally a text data type. I want to change it to a "lookup" data type using the lookup wizard. However, Access doesn't allow me to do this and prompts me with "You can't change the data type....its part of one or more relationships...". But there are no relationships? There may have been previously, but I've deleted them all from Relationships window.
This has happened several times now. I am in the process of designing the database and have been changing my mind about data types when I realize that I can use a lookup data type. The only fix I have found is to make a copy of the table in question and then change the data type of the problem field. Unfortunately this screws up my forms...which is a pain.
Why would Access say that there are relationships in the relationships window when in fact there are none?
I've attach a copy of my db. The field in question is located in the "Activities" table. The field name is "ACTIVITY_NAME". I am trying to use a lookup from the activityNames table using the "ActivityName" column.
Hi! I have a problem to build Pivot table in Excel 2003. I’m creating this table base on the “External Data” which is a MS Access 2003 table. The table has 50 fields and about 500.000 records. (This is the reason, I can’t just export table to Excel and then do pivoting). One of the fields of this table has a “text” type but stored numbers. Excel does not allowed me do Sum or Max function with this field – it needs to have Number data type. I receiving this table “from outside”, so I can’t get the right data type from the beginning. If I’m trying simply opening the table, before, using as a data source for Pivot Table, in Design mode and just change data type from text to number, I have an error: "Microsoft Access can't change the data type. There isn't enough disk space or memory." Any advice, how to change Data type in existing table using queries or something else what can help me to solve this problem.
Looks like mismatched join types has caused others plenty of headaches in the past!! I am trying to create a query that connects 2 separate areas of our factory. The first table (Table 1) has a field called prod_code which is a text field and this code (5 digit number) describes a manufactured product. The next table (Table 2) also has a field called prod_code which is also a text field, is a different 5 digit number, and describes the same product but after packaging. There is a 3rd table which I want to use to link both of these tables, but in table 3: table 1. prod_code = table 3.item_code, and is a long integer. and table 2.prod_code = table3.item_code_prnt, also a long integer. I need to be able to use table 3 to correlate data from tables 1 and 2. I suspect I need to use Clng or similar but am unsure how to apply it. Have been trying to construct an expression but continually get error (bracketing error, join mismatch etc, etc) Any clues?
I imported a big table from excel with many columns. Access when I brought it in determined that they should be "text" format. I don't want to sit and change each field to a "number-double". Is there a way to quickly change data type for multiple fields at once?
In my database i have a field for Tonnage (quantity) ...
I need for example to input 38.60 or 37.89 so my values must have 2 decimal places, ive searched and found changing my field type to double or decimal should solve the 'numbers rounding up/down' but access will not let me change the data type?
BUT IT JUST GIVE ME THE VALUE LIKE A NUMBER SUCH AS e.g. 50 ,150 but instead of that i want currency data type of that calculate field for e.g. 50 become "$ 50".
Okay so in able to do that i go to properties Sheet of the field of the query and change Format to Currency ..BUT IT DOESN'T CHANGE !!!
I've built a macro that runs through about 12 queries one after the other, which I run every day. They basically bring in data from a data warehouse held on a Pervasive server through an ODBC link, then perform calculations based on other criteria in tables held within the access database. Up until about 10 days ago, the whole thing took about an hour to run. Then all of a sudden, this changed and it now takes around 5 hours. I haven't made any changes to the macro or any of the queries which it runs. I was wondering if anyone has any ideas what might have caused this (as it's now almost unusable). I've compacted the database to remove bloat, added more RAM, moved the Access DB onto my C drive instead of the server, stopped my antivirus program from looking at either my access DB or the datawarehouse where the data comes from, pestered the network guy to find out if they've changed anything to do with the server (he says no). Any ideas for other things to try would be great, as I'm on the verge of throwing my PC out of the window in case that helps!
I am using calculated field as a data type in access 2010.
They are working fine.
However, I added a new field and now the final calc won't work.
I have Subtotal adding loads of fields together. Works fine.
Then I have a VATunit field which is a double integer, so enter 20 and my next field is VATTotal calculates the SubTotal + the VATunit by doing (Subtotal/100)*VATunit. This calculation is fine and gives me the correct amount.
The next field is a Total field. Which adds Subtotal and the VATTotal together. Howver, the Total is the same as Subtotal. It is not adding the VATTotal to it?
