INNER JOIN Based On Equivalent Values, Instead Of Equal Values
Nov 3, 2005
I'd like to create a query which will consist of simple SELECT statements as follows:
SELECT [table1].[field1], [table2].[field1], [table2].[field2]
FROM table1 INNER JOIN table2 ON ([table1].[fieldX] = [table2].[fieldX]);
The challenge arises b/c instead of joining on equal values, such as the following:
[table1] INNER JOIN [table2] ON [table1].[field1] = [table2].[field1]
I would like to join based on equivalencies, such as:
[table1] INNER JOIN [table2] ON [table1].[field1] = 34 is equivalent to [table2].[field1] = 2;
I do not know the proper syntax, so this is where I need help. I tried to search online without any success.
I have a query with an INNER JOIN and ORDER BY that is working great. Now, using the same JOIN, I need to update values in one table with the values in another. I thought it would be simple until I learned you can't do an ORDER BY with an UPDATE. Is there another way to achieve the same result? If you remove the 'ORDER BY', the statement below doesn't produce an error but the results are not correct:
UPDATE TableA INNER JOIN TableB ON (Left(TableA.CDN,6))=(TableB.CDN) SET TableA.HCC = TableB.HCC WHERE TableB.HCC Like '241*' AND TableB.BBB = 'X' AND TableA.CCC = "1234" AND TableA.HCC IS NOT NULL ORDER BY TableB.HCC, TableA.CDN;
That's an example what i want to do except i had to manually type in 25. Is there any way to get that so it does that automatically. I am happy to use forms or macros or anything as long as it occurs straight away after the data is inputted and not have to run something or open something up
I'm using Access 2010. I need to calculate a score based on values selected in a table by looking up corresponding values in other tables. I have a "Project" form to create new entries into the Project table (see Table 1). When I create a new project record, I will select values for the Payback and Need fields by selecting options from a list. The Payback list is pointed at Table 2 and the Need list is pointed at Table 3. In the below example, I created the "ABC" project and selected "1 year" for the Payback field and "Repair" for the Need field. Pretty simple.
Now that I have the "ABC" project loaded to my Project table, I'd like to create a report that will show a "score" for this project. The score should be calculated as follows: Payback Impact + Need Impact. In this example, the score should be 30 (Payback Impact of 20 + Need Impact of 10).
I have a query that uses a linked table from an external database and joins it with a table from my database to return records that contain the same values.
Is there a way to return only the records that are present in the external database and not in my db?
same as the title goes, why i can't query those figures greater than 15% only? How am i suppose to query them right?.Here is my database you cant check query1 and query 2. I am using Ms Access 2010.
When I enter a number equal to or over ten million, the last two values get rounded and I don't want them to be. My field is setup as a single, standard, two decimals. When I tested it I typed in 123456789, what I got was 123,456,800.00
enter 9999999 get 9,999,999.00 enter 10000199 get 10,000,200.00 enter 10000001.75 get 10,000,000.00
Single is supposed to handle up to 10^38
I have checked my "Region and Language" settings for the OS (W7) and there is nothing in there about rounding or maximum number size. I would like to leave the data type at single for the space considerations, and because it should work as single.
An affiliate sent us a table of email addresses, one per record. We need to find which ones already exist in our master table. Our master table contains an email field but it may contain MULTIPLE email addresses separated by semicolons. How do we create a query (or queries) which tell us which email addresses already exist somewhere in our master table?
I am trying to join two tables in a query. One of the tables has only the fullname while another has only the surname (this table is imported from an external database). I need to be able to match the two tables up. Can anyone please suggest how to do this or even if this is possible.
Is Access slower at summing null records than SQL server? I have a query which takes less than 1second in SQL server but takes about 5-10 in Access but can't think why there is such a lag in processing speeds.
I have to join multiple values into a string for summarizing data on reports and exports. This process in vba is taking up to 10 minutes to process and will get worse as the size of these reports grow.
My method so far is to query the individual items into a recordset, loop through the values, adding them to the string then return the string in the query.
Here is an example:
Public Function SO_Description(intSO As Integer) As String Dim db As DAO.Database Dim rs As DAO.Recordset Dim strSQLSelect As String SO_Description = "Profiles: " Set db = CurrentDb
I have a report in which a textbox generates numerical values and letter values. I want to...On report load - if textbox = numbers then hide otherwise show if it contains letter values.
I have the following dataset in a table called NR_PVO_120. How do i pick out a number (which can change but let's say, 6) of UNIQUE OtherIDs without excluding any OtherIDs under any fax numbers?
So, if you pick OtherID from Row7 you then also must pick OtherIDs from rows 8 and 9 because they have the same fax number. Basically, once you pick an OtherID you're then obligated to pick all OtherIDs that have the same fax number as the one you picked.
If the number requested (6 for this example) isn't possible then "the closest number possible but not exceeding" would be the rule.
For example, if you take OtherIDs from rows 1-10 you will get 6 unique OtherIDs but row 10 shares a fax with rows 11 and 12. You either need to take all 3 (but that will raise the unique count to 8, which isn't acceptable) or skip this OtherID and find one with a fax that has no other OtherIDs and that isn't on the result set already. My result of 6 UNIQUE OtherIDs will need to contain ALL OtherIDs under any fax the existing OtherIDs are connected to.
So one solution is to take rows 1-6, 26. Another is to take rows 1-4,10-14.
There will be many possibilities (the real dataset has tens of thousands of rows and the number of people requested will be around 10K), as long all OtherIDs connected to all faxes on the result set are part of the requested number (6 in this case) any combination would do.
A few notes.
1.Getting as close as possible to the requested number is a requirement.
2.Some OtherIDs will have a blank fax, they should only be included as a last resort (not enough OtherIDs for the requested number).
This is for a fax campaign, we need to make sure no fax number is faxed twice, that all people connected to that fax number are contacted under one fax sent.
In Access 2010 I have a Data Entry Form on which I have an unbound textbox in the header that the user can put a default date in. In the body of the form is a bound textbox that records the date and the default value is set as =defaultdatestat (obviously the name of the box in the header).
Problem: The default date shows up perfectly until a value is put in any of the other text boxes.
For further info : If you put values in text boxes default value disappears; if you then push escape the default value reappears when the values in the text boxes disappear.
I have several result fields which are all drop down lists. I want each result field's drop down list values to be different depending on the selected value of the Test1 drop down list.I came up with using the .rowsource keyword. My syntax seems to be fine but I'm not getting any values under the result fields when I run the form.Here is my code so far:
Private Sub Test1_AfterUpdate() If Me.Test1 = "Stress Echo" Or Me.Test1 = "Stress SPECT" Or Me.Test1 = "Stress PET" Or Me.Test1 = "Stress MRI" Then Me.Test1Result2.RowSourceType = "Value List" Me.Test1Result3.RowSourceType = "Value List"
I had to retrieve data by grouping records based on f1 value
and i had to display f3 value as "-" if all f3 values for a f1 are distinct. If all f3 values contains the same value then i should display that value.
I should get output like this
f1 f3 1 - 2 DD
I tried a lot by taking the distinct count of the records and displaying - when count is > 1
I've put together a database for my company to track our archived files. When the files are archived, there are three important values pertaining to their location: a list number, a box number, and a barcode number. Each box has a barcode on it, so what I'd like to do is make it so that when any record has both a list and box number entered (since it is dependent on the list number to know which, for example, "Box 1" I'm entering information for), it would automatically insert the appropriate barcode number in the field. It would obviously need a seed for each barcode number to be entered before it would know which one to use, but that could either be based on the first unique entry, or entered another way. If anyone can help me do this, I'd really appreciate it. Also, if my description was insufficient or confusing, just let me know and I'll try to clear it up. Thanks!
Example: If I entered: List # Box # Barcode # 77 4 It might not know what the barcode is the first time. But once I had entered List # Box # Barcode # 77 4 366582 It would know what I was entering. Keeping in mind that I'm not showing the rest of the record, but just this end part, my next entry would look like: List # Box # Barcode # 77 4 366582 77 4 366582 ...the red representing that it would automatically fill that in, because it knows that if I'm talking about Box 4 in List 77, that must be the barcode.
I'm trying to determine the SQL to return only those records in a table which have duplicate values in each of two fields, but different values in a third field. Here's an example:
Code:
AcctNum FoodType FoodClass ------- -------- --------- A123 Apple Fruit A123 Apple Fruit A123 Grape Fruit A456 Potato Vegetable A456 Potato Perishable A789 Carrot Vegetable A001 Banana Fruit
For the above table, I'm trying to return records which have multiple entries for AcctNum + FoodType, but DIFFERENT values for FoodClass. So for the above table, the query would return:
It returns these two records because there is more than one record with for the AcctNum + FoodType (i.e. 'A456' + 'Potato'), but DIFFERENT values for FoodClass (i.e. one record has 'Vegetable' while the other has 'Perishable').
I have a question I've been trying to figure out with no luck. I have 2 fields, companyname and zip, these 2 fields may have duplicate values or they may be uniquei.e.
companyname zip billybobs 68135 dilberts 68137 billybobs 68135
what I need to do is delete all of the duplicate records where both companyname and zip match. Is there a way I can do that with a query?
Hello: Is there (simple) way that I can populate a field based on the values of two other fields? For example, in a list of new employees, if a new employee starts on Nov 30 and works in the Administration Department, his human resources contact is Mary. If a new employee starts on Nov 30 and works in Sales, his contact would be Fred. I hope this is clear! Many thanks!
Hi all, Please bear with me if I'm asking a dumb question. I've been tasked to create a database from scratch and I've not had much experience working with Access.
**My Question** Using a form is it possible to have the form automatically enter a "value" in one field based on the information inputed by someone in a different field. ie. When some one puts in a value between 0 and 20 in one field it automatically enters a 1 in the other, and when some one puts in a value between 21 and 30 you get a 2 and so on down the line.
I have a table with a few Listbox options. I want one of the columns' values to be determined by the value chosen in another field. How do I do this?
Example: In column A I choose value ABC from the dropdown. I want column B to now offer values in that list of DEF, GHI, JKL. If I chose XYZ in column A instead, I'd want the column B list to show MNO, PQR, STU. Etc.
If I want to sum the percentages from April, May and June only if a column is Not Null, how would I do that?
example
Tbl 1 PK, Month Percent
Tbl 2 FK, Month Enrolled Qty of Rx in the 1st month enrolled Qty of Rx in 2nd qtr Base (if Qty of Rx in 2nd Qtr is null then Qty of Rx in 1st month enrolled)
If Qty of Rx in 2nd QTR is NOT NULL then QTY of Rx in 2nd Qtr * Sum of April Percent+May Percent+June Percent, otherwise Qty of Rx in 1st month enrolled * Month Percent
Im getting stuck on how to sum the percents of April, May and June and then multiplying the result times the Qty ONLY IF the field is not null.
I only know how to create Query's using the design mode. I dont know how to write SQL statements.
