I'm doing up a database of hazardous chemicals, based on publicly available information from various agencies. Each chemical has a name and a number, and has different hazards associated to it. The hazards are grouped into classes, and for each class the hazard is further broken down into categories. Hence for an explosive hazard (the class) I could have categories 1, 2 and 3 based on severity. For each iteration of the hazard class and category (for example explosive hazard category 1), there is a non-unique hazard statement. Another complication is that there is a qualitative element in the classification system, and hence agencies from different countries could classify the same chemical differently. This should be captured into the database as well. Thus for every chemical, I will have to enter the Japanese classification, the EU classification, etc.
I've managed to set up what I think is a correct relationship, based on my understanding of databases. However when I generate the report, fields such as the chemical name and ID are repeated for each hazard. I would like to merge these redundant entries, so the chemical name, I.D., and any other repeated fields appear only once. In essence, I'm trying to make it such that there is only one entry for each chemical+I.D/country, with multiple hazard subentries, rather than having multiple, seemingly duplicate entries.
Hi I have search the forums for an answer to this..i have 4 fields address 1, 2,3,4 and i would just like to all all the information to one field call address..how can i merge the information..please bear in mind i am useless at access..i thought there might be a way of copying the columns and just having a merge function to do so ..but cant find anything...please help..Williebear:(
I can't get my head around this so I'm looking for some help if possible please, there are two questions, the first is:
When in the query, I want the criteria for the date selection to be a question, ie. "[Week Start Date?]" but I want the actual criteria selection to be from the start date plus 5 days, the only way I've done that so far is to do ">=[From?] and <=[To?]", which uses two questions and I don't seem to be able to do ">=[Week Start Date?] and <=[Week Start Date?]+5" which seems basically correct, but I expect I'm writing it incorrectly (basic access knowledge I'm afraid :( )
The second question (after I've got the 5 day date criteria sorted) is that the query produces a table that shows basically the following:
Name Store Date Visited Tom Bury 18/01/06 Tom Bury 19/01/06 Tom Diss 20/01/06 Dick Thetford 18/01/06 Harry Diss 20/01/06
The query is based on a part week period with the starting date ALWAYS a Monday, so no more than Mon-Sat will appear, I want to put the information into a table or query, so the result ends up as:
Name Store Mon Tue Wed Thu Fri Sat Tom Bury 18/01/06 19/01/06 'Blank' 'Blank' 'Blank' 'Blank' Tom Diss 'Blank' 'Blank' 20/01/06 'Blank' 'Blank' 'Blank' Dick Thetford 18/01/06 'Blank' 'Blank' 'Blank' 'Blank' 'Blank' Harry Diss 'Blank' 'Blank' 20/01/06 'Blank' 'Blank' 'Blank'
*Where the blanks are simply left empty, rather than putting in the word 'blank'
Essentially converting the "[From?]" (as stated earlier) or "[Week Start Date?]" to Monday, that date + 1 to Tuesday, etc, BUT putting multiple dates relating to name and store criteria onto one record :eek:
Beyond me I'm afraid, any pointers would be seriously appreciated, I expect I'm approaching the problem from the wrong angle.

I really never use Access but a client gave me a database with a couple thousand records in it. Two columns were "Area Code" and "Home Number". What I have to do is merge those two so that the area code and number appear in a single column. How do I do this?
Each pay period, I must enter data for each employee that worked an extra shift. The table is simple:
Name Period Starting Period Ending Number of Extra Shifts Worked
Is there a way to bulid a form that will keep the dates I type in the period starting and ending fields until I change them?
To clarify, I have 17 employees who worked extra shifts, and I don't want to have to type in the Period starting and ending dates for EVERY record. Thanks in advance for any help. I really appreciate it.
Now, I'd like to create a form that can enter information on the employee, including the department that they're a part of. I'd like to avoid having duplicate departments in tbl_DEPARTMENTS, but I want new department entries to be created if an employee from a new department is entered into the form. I'd like employees from a previously existing department to get associated with the department entry already in tbl_DEPARTMENTS. Is this possible? What's the best way to do this? I've tried every way I can think of, but I can't get this to work.
Builder Subdivision Lot Number Lot Option Lot Materials Details
The [Lot Materials Details] table is populated by appending data from the [House Type Details] table tree as follows:
Builder House Type Elevation Options Per Elevation House Type Materials Details
The filtered Option Table in both branches determine which [House Type Materials Details] records get appended to the [Lot Materials Details] table.
The question is: Is there any advantage, other than simpler queries later on, to adding the primary key from the [House Type Materials Details] table to the [Lot Materials Details] table.
It’s redundant because the [Lot Options Table] contains the [Options Per Elevation] primary key.
I have an 11 million row table that lists relationships between pairs of people. There are several columns, but the relevant ones for my problem are
personA, personB, a-b_strength, b-a_strength.
because of the size of the table i'm having all sorts of problems, and i could actually cut out half of the rows, because for every row listing eg
dave, steve, 4, 5
there's another row listing the same information, but flipped round, ie
steve, dave, 5, 4
I'm sure there must be an efficient way to delete, using a query or otherwise, one of each of these pairs (it doesn't matter which). I have another column (id) that simply has a unique number for every row, ie 1,2,3->11 million, so i was thinking of something like
delete from table t1 where exists (select * from table t2 where t1.personA = t2.personB and t1.personB = t2.personA and t1.id < t2.id)
So, this should delete every row that has a mirror version earlier in the list.(i think)
What i'm worried about though, is performance: is this going to make a new temporary table for the nested select for each new row in the outer statement? I already created a table that listed the count of friends for each unique person with a make table query, and that took 12 hours to complete. I don't mind another 12 hour query, but not a 144 hour query!
Any advice welcome - thanks! (Sorry for the longwinded post)
I am using the access program to create a mailer. The fields are really basic... Name and address....
Many of the fields are going to be identical. City, state, zip code for instance.
The way we had it set up on our first try was to create the data base with all of the fields empty and to input everything over and over. I imagine there has to be a way to set it up so you only have to enter "San Diego" or "CA" once and then simply do manual entry of the names and street address.
Any help getting me started would be well eppreciated.
I work with an Access database with about 20 tables that requires considerable manual data entry. Although it is time consuming, the bigger problem is the keypunching errors that inevitably occur. A colleague of mine said that some databases can be set up so that two (or more) individuals can enter the same data into the database (basically creating two separate, temporary databases). At the conclusion of this double data entry, the two databases can be compared to see where they differ so that corrections can be made...the logic being that it's extremely unlikely two people entering the same data independently will make the same keypunching error in the same field.
Just wondering if Access has this capability, or if a reasonable facsimile of this approach exists.
I'm working on a scheduling system for my fathers company that automates some redundant tasks. Most importantly the system manages the order of processes on different parts (ie, part "tubes" may be cut, then drilled, then welded, then shipped).
I'm trying to create a form that allows for the editing and viewing of all the parts and the processes for each part for a specific work Order. Ideally the information that applies to all the parts (Work order Number, due date etc) would appear at the top of the form with all of the processes to appear beneath (Separated into groups - all the parts to be welded shown together). My problem with using sub forms for this was that I need all the records to be shown without scrolling. Is there a way to dynamically change the size of each Subform to match the required size, or is there a better feature to use?
I was able to use the UNION ALL qry. But, when I have another file (like original2) that does NOT have all the columns listed in the UNION ALL qry, I get a Parameter value box asking for the missing columns when I run the qry.
original 2IDDateGroupChristianJohnny18/6/2013A212528/6/2013B2338/6/2013C2248/6/2013D22
The UNION ALL qry includes all the possible resources ( includes all the possible column fields Christan, Johnny, and Steve).
When I run the UNION ALL qry with the original2 file, An "Enter Parameter Value" box is displayed with the mssing column name "Steve".
Is there a way to Map the original2 table into a working table with all the columns, or use VBA code to construct the UNION ALL qry to only include the existing columns? My data has variable columns and I'm trying to avoid the parameter popups.
I have a MS ACCESS 2010 database with a data table which i am trying to create a query from. I have 6 columns of data( one with an ID Field and 5 Name Fields). Below i have made examples of how it first appears as a simple query and the second will show you what i would like it to look like.
What the simple query looks like: [URL] ...
Second what I want the query to look like: [URL] ....
Currently I'm building tables and forms. My first table (called Clients) lists the details of fictional clients. My second table is for invoices.
In my invoices table, I wish to link the column for client reference (note: stored in the Clients table) to the column that precedes it. This column will list the clients’ names and is selected from a drop down list that is linked to the Clients table.
What I want to do (if its possible) is to have the respective client ref. automatically show up in the next cell once I've selected the client to whom the invoice relates?
Am I making sense? Is that possible? If so, how do I do it?
Secondly, how do I do a sum of selected columns for my “totals” column? Basically, I want to add the figures found in several cells that precede it?
I'm affraid my confusing topic title is an indicator of how confused I am by this. I can't even understand the variables well enough to fully utilize Access Help or the Search function here...
What I have is a database hat has column headers that look something like this: Customer_Name, Order_Date, Qty_Ord, Unit_Price, Total_Price
What I'm trying to get is a query output that will have
Customer_Name, Total Orders (in Dollars) for January, Total Orders (in Dollars) for February, Total Orders (in Dollars) for March, etc.
I've been able to set it up to SUM for one month, but not multiples.
I know I'm totally lame (for proof read any of my previous posts) but you guys totally bailed me out the other time I asked a lame question.
My network was using Access 2000 and Word 2000. We recently upgraded to Access 2002 and Word 2002, but now none of my merge forms are working. I don't get any error messages, and the merge function does open Word, but all I get is the original source document and not the actual merge information. I checked my VB references and nothing is glaringly missing. What's the deal?
I am new to Acess, I am trying to merge 2 Access DBs and am not sure of the steps to accomplish this, if it can be accomplished and/or are there any tools to reach the same goal.
Hi, I'm very new to access so sorry if this request seems a bit stupid.
I'm trying to get one csv file for a database of cars so I can upload it to my open-realty account.
In one table is the car ID and there are fields like Price, Extras, Mileage etc associated to that ID. (this is how I want everything to stay) I would like additional fields like Photo 1, photo 2, photo 3....photo 25 related to each car.
In the second table there are photos of the cars but each photo has its own unique ID but a field that relates to the ID of the car it is associated to.
How do I merge the two tables into one simpler version?
We are using an Access database for off-site data entry. We therefore have one master database we keep in the office and then a "template" version -which is identical to the master version except no records - we bring to each site, do the data entry and then merge that data back into the Master database.
Can anyone help suggest ways to make the data merging process more efficient. The database has approx 12 tables, so I dont' want to create an append query for each one every time. Is there a way to just "merge" two identical databases??
I am trying to import some data (job details for a machine shop), that is being exported from a CNC program.
The export has all the information we need, in a delimited format, but it spreads this over several lines. I also contains lots of junk we don't need.
Access imports this, but those lines then form an individual record in a tempory table.
I missunderstood what the 'UNION' query was, and whilst this has created nicely organised data, with just the stuff we need, it gives it over 3 individual records.
I either need to combine the 3 records from the output of the UNION query into a single record, or (and I suspect this is the case, as the UNION query doesn't actually do anything if I think about it), find a way of combining different fields from the temp import table into a single record in the query.
I've done a fair amount of searching on 'merging records', but can't seem to find a similar problem. Can anyone point me in the right direction?
Hello I need to merge a set of Access tables. I am creating a database which will hold a large amount of records (upto 250 000 in one table). I am importing the data from an excel spreadsheet. As each spreadsheet is limited to 65000 records I had to save the file in 4 different spreadheets. However in Access I need all these files saved in one table. Can anyone please help me?
Hello first post here, I need some help!Sorry not sure if this should go under queries or tables.Anyway I'm working with quite a large access db (64mb).I want to merge data from several tables into one table.Its a supermarket db (not a real one). Its got a customer and product tableIts also got a table called agg_c_special_sales_fact_1997with the fields customer_id and product_id this shows what customers bought what product.I want to merge the data from customer, product and agg_c_special_sales_fact_1997 into one big table. I want the merge to be permanent so I can see the which customer (and all their details) bought which product (all details) in one big table. I ve been trying to do this all day (im quite new to SQL) I copied the data in agg_c_special_sales_fact_1997 into a new table "new_sales_fact". I added a row called brand_name to that I want to copy from the product tableSo far I ve come up with this:SELECT product.brand_name INTO new_sales_fact FROM product, agg_c_special_sales_fact_1997WHERE product.product_id = agg_c_special_sales_fact_1997.product.id;unfortuantely access asks me enter a parameter value when I run the query.Could this becuase agg_c_special_sales_fact_1997 is huge, its got 86,000+records?Can anyone help? I'd be most greatful this has been driving me insane all day!!thanks in advance! P.S the database is the test database that comes with Mondrian......P.P.S I know its not good practice to have all data in one big table but for the purposes of what im doing it will simplfy things a lot!
I'm not really an Access programmer, but I maintain a couple of databases for my own use (music collection etc.). I hope no-one minds me posting here :)
I've made a bit of a mistake. I had two copies of a database on different machines, and I entered new data into both of them.
Is there any way of merging two tables, discarding any records which are identical?
