Join Two Tables Based On Field

Jul 25, 2012

I have two tables: Focus and Comp..I want to join these two tables based on field: DwId...For this example, I made a Comp table that has 3 DwId's not present in the Focus table.When I run the below statement, I am not getting the 3 records only present in the Comp table in the result.

SELECT Focus.DwId, Focus.PRD_May2012, Focus.PRD_May2012 - Comp.PRD_May2012 AS PRD_DiffMay2012
FROM Focus RIGHT JOIN Comp ON Focus.DwId = Comp.DwId

Create A JOIN Of Different Tables Called Join A Variable And List

Nov 16, 2013

And then called this join as a symbol or variable, and then have it use to select the items from these joined tables, can this be done in Access? Here is an example of a code that I created, but it has an error message saying the FROM syntax is incorrect.

Code:
SELECT firstJOIN.trainID, firstJOIN.trainName, firstJOIN.stationID, firstJOIN.stationName, firstJOIN.distance_miles, firstJOIN.time_mins
FROM (trains INNER JOIN ((station INNER JOIN lineStation ON station.stationID = lineStation.stationID)
INNER JOIN bookingLeg ON bookingLeg.startID = station.stationID or bookingLeg.endID = station.stationID )
ON trains.trainID = bookingLeg.tid) as firstJOIN

Can Access do something similar to this, in the FROM statement I joined 4 tables, because each unique fields are in each table and I have to joined them to get those fields. I called this join firstJOIN and in the SELECT statement, I list those columns in the table by calling it firstJOIN.trainID. Can Access do something like this, but syntax it differently?

Tables :: Cannot Enter Value Into Blank Field On (one) Side Of Outer Join

Apr 28, 2014

My goal is to create a form that allows me easily edit what State each City is assigned to, and edit what Country each State is assigned to. I have 3 tables:

tbCities
CityID (Primary Key)
StateID (Foreign Key from tbStates)
City

tbStates
StateID (Primary Key)
CountryID (Foreign Key from tbCountries)
State

tbCountries
CountryID (Primary Key)
Country

For right now, I want to focus on just States and Cities... so I also have this query:
quCity_to_State
Field: City
Table: tbCities

Field: State
Table: tbStates

The join type for the relationship between tbCities and tbStates is: Include ALL records from 'tbCities' and only those records from 'tbStates' where the joined fields are equal. That way I can see all the cities and the state they are assigned to.

However, when I view the query in datasheet view and try to type anything into the State field of this query, I keep getting this error: "Cannot enter value into blank field on 'one' side of outer join". I figured the source of the form should be this query instead of the tables directly, but if I can't input data into the query then I wont be able to input data into the form.

What am I doing wrong?

Tables :: Auto Populate Field Based On Answer Of Another Field In Same Table

Feb 28, 2013

Within my table if Field 1 has an answer of Self (from drop down), then, I would like Fields 6-12 to auto populate; however, if Field 1 does not have an answer of Self, then leave Fields 6-12 blank.

I am not quite sure how to lay this out. I am using Access 2010.

I (will have) a form which a user fills in to enter new data.

I have two fields,

"Branch" and "Branch ID" (Branch ID will not be on the form, just in the table)

Branch will be fed by a combo box with seven choices. I would like it so that when "Branch" is populated it autopopulates Branch ID with a code which relates to the branch, so for example

BRANCH BRANCH ID
Braintree BRA

Tables :: Autopopulation Of Field From Another Table Based On Another Field Criteria

Dec 5, 2012

I have a main table which is autonumbered on unitid, I have another table which is linked via the unitid which holds items purchased for the main table, so the second table is a subform of the suppliers and will have multiple entries of the same unitid. What I would like to do is when an item is entered into the second table, check the main table to see if it exists, if it does populate the unitid field with the unitid from the main table, and if not exist create a new record in the main table with the next unitid number.

This in essence is what I want, bearing in mind that the tblinvoices is a subform and the tblmain is not open.

If ([tblinvoices]![Unit] = [tblmain]![Unit]) Then
[tblinvoices]![UnitID] = [tblinvoices]![UnitID]
End If

Tables :: Automatically Fill Field Based On Keywords In Another Field

Dec 3, 2013

I'm trying to complete a database.

It is to manage details of pupils with additional support needs, and plan for the extra arrangements the school will provide for assessments.

It has 2 Tables

tbl-PupilDetails
-ScottishCandidateNumber primary key (Unique number which identifies pupils to the exams board)
-Forename
-Surname
-DOB
-YearGroup
-Class
-NatureOfNeed (memo)
-EvidenceOfNeed (memo)

tbl-SubjectLevelArrangement
-ID Primary key, Autonumber
-Pupil foreign key to tblPupilDetails
-Subject
-Faculty
-Level
-Arrangement

I currently use forms for adding new pupils, and updating pupil subjects/arrangements/levels.

I also have forms to search for specific pupils, and to create lists for faculty heads showing which pupils are taking subjects within their faculty and the arrangements we expect to provide.

I use the forms to run queries, which can then output to reports for printing.

Where I am currently having an issue is the faculty field in the tbl-SubjectLevelArrangements. (If I didn't have to report to faculty heads I would just leave it out, but management will insist.)

Currently I have a form with dropdowns for adding subject, faculty, level and arrangement manually. This is acceptable for the subject, level and arrangement because they are completely interchangeable and dynamic throughout the academic year as pupils may drop down a level, or change the type of arrangement they require.

However as faculties are inextricably linked to subjects, I want to remove the possibility of human error. i.e. when a user (me) chooses either geography, history, or RE, then the faculty will always be Humanities, likewise if the user chooses French, German, or Spanish, then the faculty can only be Modern Languages etc.

I'm convinced there must be a very simple way to ensure that the faculty field prefills based on the limited keywords available in the subject field, but I just cannot figure it out.

Tables :: Calculate Value For A Field Based On Value Of Another Field - Statement

Dec 30, 2012

I'm trying to calculate a value for a field based on the value of another field, [Field1] has a value list of 28 choices I want [Field3] to take that value and multiply it by the value of [Field2]. I'm using an Iif statement and it sort of works. I looks like this:

IIf([Field1]=1 Or 2 Or 3 Or 4 Or 11 Or 12 Or 13 Or 21 Or 22 Or 28,[Field2]*0.06,IIf([Field1]=5 Or 6 Or 14 Or 15 Or 23 Or 24 Or 29,[Field2]*1.1,[Field2]*2.1))

I receive nor errors but it will only return the value of [Field2]*.06 no matter what is selected in [Field1].

I'm sure I'm missing something and there is probably an easier syntax to use, but I'm at a loss at the moment.

Tables :: Fill One Field Based On Another

May 24, 2013

I'm creating an accounting database for my use at work. I order goods and services from a multitude of vendors, using varying payment methods, and at last count, 8 different accounts. The time I'm spending on repetitive entry into excel spreadsheets has forced me to sit down and make an access database to track everything.

Right now, the following:
1) Table named "Accounts" with two fields - Account # and Account Description. Account # is PK.
2) Table labeled "Orders", which I'm going to have the top-level information for each order (order #, Account #, Account description, + others that don't matter here). I have another table for the order details (product #, description, price...).
3) Relationship between "Accounts" and "Orders" is one-to-many, enforced referential integrity, cascaded update.

For my order entry form, I want to enter the account description, so I set up a combobox. But, for my paperwork, I am going to need the account # to print when I do a report, and for future flexibility I want that field to remain in the "Orders" table.

I know my accounts by name, not number, and I want it set up so that when I select, for instance, "Supplies Account" for the description on the form, the Account # field on the Orders table is automatically populated with the account # that correlates to that description.

Is there a way to tell the table to auto-fill this entry?

Tables :: Way To Track Changes Based On Different Field Name

May 13, 2013

All; using Access 2010. I need to have some kind of way to track changes based on different field name.I have a client table with field data like Fname, Lname, SSN, Address, Zip, Phone, DateOfBirth, Current Rate, TotalRate, Status and Importdte. I have an import into the database every month and I update this table with data that is new based on the SSN with an append query. The import also has the names of those that exist in the client table until their status changes. In addition to appending new data every month; I would like to append any changes the existing client has. For ex; If an existing client has an address change, I want to append this data to the table but keep the existing address and have a Change date equal to the Importdte. In essence; I want to build a kind of history table that when I pull up a client; I can have something like a tab on a form with the changes and when it happened.

Tables :: Autopopulate Field Based On Contents Of Another

Sep 12, 2013

I am in the process of revamping an old database. I have a main table that currently has two fields "Name" and "Job" but will have more. I have another table with the same fields. I want to use as a lookup to populate the main table with a user form from the second table. I can populate the "Name" field using a combo box, but my problem is how to autopopulate the "Job" field. E.g. If the user selects Mr Smith from the "Name" drop down list, the corresponding "Job" populates the second field.

Tables :: Update Table Based On Concatenated Field

Aug 8, 2013

I have a field in a table that is to be concatenated from two other fields, PolPrefix and PolNum. On a form I got it to show the full field 'PolicyNumber' by making the control source =[PolPrefix] & [PolNum].

But this doesn't update the field PolicyNumber in the respective table, and only shows it on the form. How do I get a concatenated field defined by the user into a table so that I can call that field other places in the database?

I am very new to access and I am trying to figure out how to build an expression for one of my fields. I have a field called Order Date, which holds the date of when an order is filled. I then have another field called Fill By Date. This new field I want to be 2 weeks after the Order Date. Is there a way to auto fill this information so that when I enter a date into the Order Date, it will enter the date that is 2 weeks after into the Fill by Date?

Queries :: How To Join The Table With Query Based On Like Clause

Nov 18, 2014

how I can achieve this in Access

I have a table created in Access- "Master"

FileName Sortorder
ABC_..........4
CDE_..........2
EFG.ss1.......1
GHI.srs........3

I have a Query created in Access whose output is

FileName RowCount Exception RunDate
ABC_20141117.....10...........5........11/17/2014
CDE_11172014......23.........10.......11/17/2014
EFG.ss1................55..........0........11/17/2014
GHI.srs.................15..........5........11/17/2014

Now I require to join these both, the table and the output of the query on the condition where query.fileName like table.fileName.

There is no key in this field. Why I need this because the table has the sort order which the user can change when needed, if I put the sort order in the query then each time there is a change then the query needs to updated which the user can go wrong. Also the filename in the query has date associated which changes every day so I need to pick the unique part of the file name and associate it with the query to get the output from query and sort order from the table.

Required Output:
FileName RowCount Exception RunDate SortOrder
EFG.ss1...............55............0.......11/17/2014...........1
CDE_11172014.....23...........10......11/17/2014......... 2
GHI.srs................15............5.......11/17/2014..........3
ABC_20141117.......10...........5......11/17/2014..........4

Queries :: Join Two Databases Based On Common Text

May 31, 2013

I am trying to form a join between two separate databases. Database 1 has a column (Gene_Name2) that consists of common names of human genes. In this database there is only one name for each gene per field. The other Database 2 has a column (Gene_Name2) that has various names for the same gene in each field. Most genes have been given different names over time.

I want to join the databases into a separate query database so that all of the information in Database 1 is retained and only when the name in Database 1 matches one of the names in Database 2 does the row of information get tacked on to the query database. The problem is that in a normal query the text in both Gene_Name columns do not match and the query returns no matches. I have tried Instr and like criteria statements with no luck. The following is an example of what I have and what I need.

Database 1

Chrom Gene_Name1 Data
Chr1 ATC XYZ
Chr2 IDH2 ZYZ

Database 2

Gene_Name2 Data
ATC;ORF34;NM_123 ABC
ORF65;IDH2 IGH

Joined Query
Chrom Gene_Name1 Data Gene_Name2 Data
Chr1 ATC XYZ ATC;ORF34;NM_123 ABC
Chr2 IDH2 ZYZ ORF65;IDH2 IGH

Queries :: Complex Join Based On Date Range

Jul 29, 2013

Context is I have a TABLE 1 that has a record for every package shipped with various details about it, include how it shipped, and the date. Table 2 is a key to go from the ship method to a better grouping we deem service level. Table 3 is a Fuel Surcharge (FSC) Table. It includes various FSC % that vary by different service levels and different date ranges. In the end I need to know the amount of pkgs shipped (by month and servicelevel) and the relevant FSC.I have several tables in my database but we should be able to focus on 3 to explain my situation and only the relevant fields:

TABLE 1 (Main Data):
ShipDate
ShipVia

Table 2:
ShipVia
ServiceLevel
FSCType

Table 3:
FSCType
StartDate
EndDate
FSCPercent

DESIRED RESULT:
Month
ServiceLevel
FSCPercent
PkgCount

Table 1 is Left join on Table 2 based on ShipVia
Table 2 is Left join on Table 3 based on FSCType
The issue is Table 3 is dependent on Table1.ShipDate being between the date ranges as well.

There are overlapping date ranges, however they are differentiated by the FSCType field.The only semi-feasible solution I currently have is to expand Table 3 to include every date, and not date ranges. This will create an issue due to size of date ranges etc.

Join Tables SQL = Problem = My Tables Are Not Normalized

Dec 15, 2005

Okay - the other database is in the works and is going sloooow (the one that is being created with normalization).

Meanwhile, my other database that has no normalization I am having a problem running a query (now I know why its so important to have good structure).

To give you an idea on how bad this is...:o .....

3 tables - 94 fields to each table - each table has identicle fields, just different data. :eek:

Anyways, I have students in each table (each table is an Annual Report). I want to be able to run a simple query and combine all the students into one.

How would I achieve this?

Thank you!

And for all who are thinking about designing a database - READ READ READ and do some more reading on normalization!!!

Tables :: Auto Generate Hyperlink In Table Based On Field Name

Aug 29, 2014

I Have a table with 15000 entries. This table lists components we use. This table is used to generate queries/forms. I have been asked to add a hyperlink to this table to link to a drawing of the component. All the drawings are in PDF and in the same folder. I am looking for a way to automatically update the hyperlink fields all at once. The Hyperlink will be in the format of servershareddrawings12345.pdfwhere 12345 is the component name from the table.

But there are a few small problems with the component names.
1. If the component begins with a B- . The drawing name will be all the characters except when there is a second dash in the component. So if the component is B-12345-678 the drawing name will only be B-12345.
2. If The component begins with AB, The drawing will be the first 5 characters regardless of what follows, e.g. AB123.
3. Finally for all other components the full component name will be the drawing name.

Putting the naming to one side, how to go about auto generating the hyperlink. I have posted this in the table section, but maybe this should be in another section like queries or VBA.

Tables :: Populate Date Based On Specific Text In Another Field

Mar 27, 2013

I would like the "DateOfConfirmation" to populate with today's date when "SSurvDiagThisYear" is Confirmed.

The DateRecordCreated is a simple =Date() that populates when the record is entered into the table.

SSurvDiagThis Year is the case outcome - Pending, Probable, or Confirmed. It is possible that the case could be confirmed on the same day it was entered into the table but that is RARE.

I am hoping for the The DateOfConfirmation to capture the date the case is confirmed so that I can gather some duration between the case being opened to confirmed.

Tables :: Update A Field In One Table Based On Status Of A Field In Another Table

Aug 2, 2013

I have started work on a database to track the many (several hundred per annum) projects my company undertakes. A 'main' table lists projects, their fees, their key dates, their project numbers, etc. I have created another table for tasks. Each task is assigned to a project (via the project number), and may be 'open' or 'closed'. I have separated the tasks table from the projects table as there may be several different tasks for each project. It is also good to keep a record of the tasks.

I want to prepare a report from the projects table that lists projects IF they have any open tasks.

In my mind, this means 'If a task, with the corresponding project number, is open, put a 'Yes' in the 'Tasks open' field of the Projects table.'
