I am new to access database. I have a Payroll Table with several fields. In that table whenever I insert a new row in to that table, I want to display netpay field to be filled automatically. I want to calculate
[Grosspay] - [OtherExpenses].
Im Googled and saw many examples but I am not getting the exact one what I wanted. In one example I found changing the datatype of automated calculated field to Calculated datatype. But in my database I don't find that. I am using access 2007

I have two questions both related - I have a table with column headings - based on this table is a query and a form. If I add another column heading to my table how do I get the query and the form to update and show the new table column heading - I have some VBA knowledge but not enough to work this out - thanks Dave
You mentioned sql and forms. Are you utilizing MS Access?
If you are, you will need to add the new field in the sql query, then add the new field into the form.
Not knowing what you are working with or examples of how it is laid out limits what help I can offer.
I have a database, which contains information that I can't share images of due to compliance reasons.
I have a table I need to copy data from, so I was using the following SQL:
INSERT INTO completedtrainingstestfinal (MALicenseNum)
SELECT MALicenseNum
FROM CompletedTrainings
WHERE (CompletedTrainings.MALicenseNum IS NOT NULL)
AND (CompletedTrainings.Employee = completedtrainingstestfinal.Employee);
It keeps popping up the Enter Parameter Value, centered on the new table (named completedtrainingstestfinal) at the Employee column.
Background: The original table is a mess, and this is to be the replacement table, I've had to pivot the table in order to clean it up, and am now trying to remove an ungodly amount of nulls. The goal is to clean up the query process for the end users of this who need to put in training and certification/recertification through the forms.
When you look in the old table, it has been designed to reference another table and display the actual names, but as seen in the image below it is storing the data as the integer number Employee.
The new table Employee column was a direct copy but only displays the integer, my instincts tell me that the problem is here, but I have been unable to find a solution. Anyone have any suggestions to throw me in the right direction?
Edited to add: It might be an issue where the tables have different numbers of rows?
This is the design view of the two relevant tables :
Table 1
Table 2
Recently I have been using Microsoft SQL for creating databases that are referred to using an excel document. There have been a number of instances when I needed to make a small changes to my tables and ended up "DROP"-ing all my current tables and re-creating them using an updated query. I understand you can use UPDATE to change the values of records within a table, but I'm looking to manipulate a data type so that I can change the number of decimals in one record of my tables from 2 to 3. Code for creating the table looks something like this:
CREATE TABLE WIRE_INDEX
--"Field" "Data Type" "Null or Not"
(...
...
DENSITY decimal(18,2) Not Null);
I don't know if the solution is something obvious, but I have been unable to find anything useful. I'm not sure know how to refer to the data type of a field in SQL.
When I populate the database I use numbers like 0.283 and 0.164, but when I SELECT the record I only get the first two decimals. I'd like the first 3 decimals to appear in the way I enter them into the table.
(edit didn't show up properly)
(not sure if I'm supposed to post my solution), but credit to TEEKAY and Apurav for answering my question. I used the code posted by Apurav which looks like this:
ALTER TABLE WIRE_INDEX
ALTER COLUMN DENSITY decimal(18,3) Not Null
When I pulled the table, using a SELECT statement the precision showed three decimal places, but I lost the precision of my input and had to re-enter my values using UPDATE. Not sure if this is more effective than just starting over, but it worked for me and now I know.
I have a table with a bunch of different fields. One is named period.
The period is not part of the raw data but I run a query when I import new data to the database that gives each record a period.
Now I need a delete query that will delete all the records that have the same period as what is selected in a combobox.
The values in the combobox come from a calendar table that contain all the possible values that could be in that period column at any time.
This is the basic query i thought would solve this issue but it tells me it is going to delete 0 rows every time I run it:
DELETE *
FROM PlanTemp
WHERE PlanTemp.period = Forms![Plan Form]!Combo163;
If you don't need the key field, just remove it.
Look at the "PROPERTIES" section and look at the column names.
Ether remove it there, or from your QUERY source.
You can also look at the Data section of the properties, and change your BOUND column, to Column 2... or whatever holds the data you want to use.
I have a spreadsheet that lists customers, their supervisor information, and special feature codes that are listed on their account at the time the report was created.
I need to add a column to this sheet that lists the last active date that these codes were populated on the customer account.
I'm aware of how pull the info when the features were last active. However, I need to base my query based on these specific accounts and codes. What family of SQL Clauses can I use to read these preexisting values and return a corresponding date value?
Your question is a bit ambiguous. How are you populating the spreadsheet? Are you using an ETL application like SSIS or creating an Excel output from a SQL query in your database?
If you are populating an existing Excel spreadsheet, then create in that spreadsheet a new column called "Last Active Date" in preparation for populating it from the source.
If you are pulling the data from a database source, then there may be an associated history or archive table where you can find the pre-existing codes along with their corresponding dates. Here your database administrator and/or developer will be better equiped to assist you in navigating the database architecture. If the codes are no longer available in the source database, then no special SQL CLAUSE will assist. You cannot retrieve that which does not exist.
