Update Tables With Missing Data Without Using Unmatched Query?
Aug 13, 2013
I have an access database with several linked tables (linked to MySQL database) and several local tables. The theory is that if there's ever a connection issue, the device connected to the computer will continue logging data to the local tables. Once a connection is re-established, the linked tables should be updated with all the missing records which appear on the local tables.
I found several possibilities which I outlined below, but I've been asked to investigate whether there's a built in function in access that does this for you and use the other options as a last resort. Does access have any program feature that updates one table with missing data from another table, or will I have to write VBA code to do that? Options I've discovered:
1) Write unmatched query and insert missing data into table.
2) Create a linked table on MySQL that will link to the local tables on access, then compare the records there.The boss isn't happy with those options because he wants to keep the amount of code we add to a minimum. Ultimately, we hope that a program feature that does this is built in to access. If not, I have no problem adding code to do this instead.

I need to design an unmatched query on 2 tables to identify employees names that exist in 1 table but not the other (or names are misspelled, etc.). The tables exist in on a server and I do not have the ability to change either. Table 1 has the following structure:
EMPLOYEE NAME: Doe, John ID-12345
Table 2 has the following structure:
LAST NAME: Doe
FIRST NAME: John
Since the field names are not equal, the unmatched query wizard (as far as I know) will not work. I've tried using "NOT LIKE", LEFT JOINS, RIGHT JOINS, NUll Values, etc. in the SQL but nothing has worked as yet.Here's the SQL I've been working with but this returns all values (haven't figured out why):
SELECT DISTINCT [Table 1].[EMPLOYEE NAME]
FROM [Table 1], Table 2
WHERE ((([Table 1].[EMPLOYEE NAME]) Not Like "([Table 2].[LAST NAME]*"));

I am importing the updated Employee Roster information from Excel to a table called "Weekly Roster Check" (contains new info). I have a table called "Current Chit Board" that has an Employee Roster that I update every week (contains old info). I want a query to find employees who are promoted and their title has changed. then I want to run an update query to update these results to the Current Chit Board table.
Every method I try, returns either no information or information that is not what I want.

I am trying to create a query that matches two other querys and finds records that are in the primary, but not the secondary query. I have tried to use the query wizard for this, but it will not work for me the way I want.
If I have A,B,C,D in one query and only have A,B,D in the other I want to find C, so that I can format an email funtion in my database using that data.

I have 2 tables: one for repairs and the other for the billing for those repairs. There is a foreign key(record_num) in the billing table to match the primary key(prikey) in the repairs table. This works fine as long as the unit repair has been completed.
Now an employee wants to see records even if they are not completed and wants the rate to be $0.00 if the unit has not been completed. But by this method there is no record in the billing table.
My problem is if I have the 2 tables joined then I only see records that match both tables. Here is my SQL for the query:
SELECT DISTINCTROW tbl_module_repairs.end_user, tbl_module_repairs.pickup_date, tbl_module_repairs.complete_date, IIf([pickup_entity]="Storm","APS Storm","APS Field Tech") AS [Repair Pickup], tbl_module_repairs.mfg_part_num, tbl_module_repairs.manufacturer, tbl_module_repairs.module_type, tbl_module_repairs.incoming_module_sn,
[Code] ....

I'm trying to create a single, Update Query in Access 2007 that does all of these 3 things:
Update (skipping zero-length values)
Append
Automatically handle missing Fields without showing any "Enter Parameter Value" prompts.
I've managed to accomplish the 1st & 2nd items on my own, but I'm stumped on the 3rd. In essence, what I'm looking for is a way of telling Access to automatically use a zero-length/null value for any missing Field(s) the Query encounters, so long as it does not involve manually modifying the Table beforehand. Automation is key. And that's where you guys come in.
Attached, is a diagram of the desired results applied to a set of sample Tables. And here's the SQL code for the Update Query adjusted to work with those sample Tables:
Code:
UPDATE Table_1 RIGHT JOIN Table_2 ON Table_1.ID = Table_2.ID SET Table_1.ID = NZ([Table_2].[ID],[Table_1].[ID]), Table_1.Company = NZ([Table_2].[Company],[Table_1].[Company]), Table_1.Address = NZ([Table_2].[Address],[Table_1].[Address]), Table_1.Phone = NZ([Table_2].[Phone],[Table_1].[Phone]);

I've got an Excel sheet with +700k rows and 20 columns that I wanted to import to Access. All fields are text except the field that I want to use as a primary key, but I planned to import that as a text as well.
When I used the import wizard, I set all fields to import as text except for three that I set to memo. The wizard didn't say there was any error after importing the data, but when I checked the table, I noticed there were *a lot* of records where many fields where blank. Some fields where completely unaffected by this problem throughout the entire table, but in the rest of them, there is data missing in many records, and when there is data missing, it is not always the same fields that are missing. I have been unable to find any pattern that explains why sometimes the records were imported correctly, and why sometimes they were not.

I want to use a column in a query to show where data is missing in other fields.
In excel I have used this statement:
=IF(COUNTA(I5:J5)=2,"","error")
Basically, I have two fields PRICE and WEIGHT. I want a column in the query to show 'Error' (or any kind of flag) when either (or both) of these fields are blank.
Hope this makes sence.
Any advice?
Thanks

is there an easy way to merge all of this data into 1 table easily. ive tried using make table or append queries, but it only addes the information where the IDs are in each table. this leaves out the ids that are in only 1 or 2 tables.
if you need me to clarify or explain anything else, please let me know. i can post screenies or the design, but obviously, not the data.

I was able to create a query that selects records from one table that have several fields which don't match with another table.
The end-game with this query is to have it delete the records in table 1 that don't match records in table 2. The delete query tells me that it could not delete from specified tables.
I've attached the select query, the delete query and the error, and the relationship table for the db.

I have to make a Costing System but for that I need to enter our Expense details in database according to Fiscal year and months.
I need a table for Fixed expenses and one for Variable Expenses and then I need one or more Forms to update data in those tables. Now I've created a table with Fixed Expenses. I have to update Year and Amount in that. Now it is only letting me one entry per Expense.
I want multiple entries for one Expense say 'Advertising' for different years. I'm thinking may be I need to make more than one Table, may be one for Expenses with ExpenseID and other for Years with Year and YearID and the third one for Amount with columns Amount, Method of Payment, Date and Notes. I did tried this but I think I'm not creating proper relation may be because its only updating for one year.
I'm using Access 2003.

Hi Guys,
I have got a query that updates details from one table2 to table1, "Reference" is the primary key and this is what the query uses to determine which need updating.
It all works great but if table2 contains a record in "Reference" that is not in table1 i just want it to ignore it, currently it just seeems to add them.
Any suggestion guys & gals?
Many thanks

I created an unmatched query with the wizard and it works fine - when I want to compare with only one field. Is there anyway possible for it to compare two fields? I need for it to look at field1 and field2 when checking for unmatched records. Any ideas?

I have a query in an Access 2003 database that list fields from two tables. I want a query based on this query to pull out records where the interest rate does not match the PrimePlusMargin. See code below:
SELECT [95_1324].ACCOUNT, [95_1324].[CLIENT'S NAME], [95_1324].[OPEN DATE], [AR PlanDefinition].[ARL Plan], [95_1324].[Interest Rate], [AR PlanDefinition].Margin, 6 AS Prime, [Prime]+[Margin] AS PrimePlusMargin
FROM 95_1324 INNER JOIN [AR PlanDefinition] ON [95_1324].[ARL Plan] = [AR PlanDefinition].[ARL Plan]
ORDER BY [95_1324].[OPEN DATE] DESC;
I think I figured it out but it doesnt work completely. I created another field called "No Match" and set the criteria to "No Match" See code:
UnMatch: IIf([Interest Rate]=[PrimePlusMargin],"Match","UnMatch")
When I run the code, the pop up parameter asking for PrimePlusMargin. I know I spelled it correctly. If I just say ok, it returns all records. PrimePlusMargin is an alias field. Does this matter?

I am trying to do the good 'ol sales report (query) to include customers with no sales.
I have a customers table, account number table, sales table & sales (line) detail table. (all linked in that order)
If I run a query to show customers (in the customer table) with account numbers, that works
An unmatched query to show customer without an account number works (but of course the unmatched account number field isn't shown).
How can I get the two two be shown together with the "unmatched" having a null or 0 for their account number?
I am guessing in principle, the resulting solution can be modified to show customers without sales alongside those with sales?

In table 2 I have some document #s e.g.

Hi there, I currently have the below tables:
tbl_stores
ID NAME
123 Store A
456 Store B
tbl_returns
ID NAME RETURN
123 Store A 9999
123 Store A 8888
789 Store C 9999
I want to find the stores that exist in the stores table, but not in the returns table WHERE the RETURN is equal to 9999. This would hopefully return 456 Store B
My problem is when I put a condition in my query it returns nothing as the condition is based on the left joined table.
SQL
SELECT tbl_stores.store, tbl_stores.name
FROM tbl_stores LEFT JOIN tbl_returns ON tbl_stores.store = tbl_returns.store
WHERE tbl_returns.store Is Null AND tbl_returns.survey_id=2
GROUP BY tbl_stores.store, tbl_stores.name, tbl_returns.store
Any ideas? Thanks for your help with this one!
Cheers
Tony

I have a table listing 147 Company training Policy# with each Position to which each policy applies. Not all Policy# applies to every position, i.e. Driver versus Office staff. There are 32 employees in 7 different positions.
I have a table of Employee Records with standard information including Employee ID and Position.
I created a select query from the Employee Record and the above training requirements that provides a data list of every employee to each pertinent training policy by inner joining Positions with three columns Policy# and Title from the Policy# table and Employee ID from the Employee Record table.
I am trying to create a query that will tell me by Policy# what Employee has no record of being initially trained in that particular Policy #. I have built a query but it doesn’t give me a complete listing of missing employees.
SELECT qryPolicyByEmployeeID.CWSPolicy, qryPolicyByEmployeeID.EmpID, qryPolicyByEmployeeID.Title
FROM qryPolicyByEmployeeID LEFT JOIN TrainingLog ON qryPolicyByEmployeeID.EmpID = TrainingLog.EmpID
WHERE (((TrainingLog.EmpID) Is Null))
ORDER BY qryPolicyByEmployeeID.CWSPolicy, qryPolicyByEmployeeID.EmpID;
My problem occurs at the “Where” statement. When inquiring on a specific Policy# and the EmpID is in the training log for any other Policy# that EmpID does not appear in the listing. I am trying to figure a way to get around this.
Has anyone a suggestion as to how I can make that happen? I am very flexible about changing table layouts if that will get me what I need.
