The file is huge with many sections (eg Names, Address) in it. What I need to do is load it into Access for some analysis.Is there a way I can split the file one loading to the system into multiple tables?
How do I know when I should split a db into multiple tables? Right now- everything is in one table. Is there a rule of thumb or method to determine when I should split it up?
For example- MY DB is running queries on properties for sale. Would I split all the Active, Sold, Expired, Off Market listings into separate tables, since I will be frequently queriing based off of the status of the property? ie- I'll be running avg prices of homes that are in each of these status. If that's the case, how do I know what relationship to give it/how to set it up (use the MLS # as the primary key in each, or do I need a foreign key or something else?)
Is there a general rule of thumb, or guide to use when designing a db?
I am trying to split a number sequence (Ex. 25372-400-E10-0000-D0021) Where the third number in the sequence can be either 2 or 3 numbers/letters.
The idea is to have a query that will split this number into its individual parts. I have seen several forums about splitting two numbers and such but I can't seem to make that work when I need to create 5 columns from this one field.
I've got a module which loads the data into a table, but it can't handle the records that are ~ delimited, so spits them out as a single field.
I know there is some VBA code that can be used to split comma delimited records, and I've seen bits of it floating around online and tried to alter it to work for the ~, but I get the feeling that what I've seen is only a part of the required code, how to put it all together to make something that actually works.
So, what I need to do is; - Split some records in a table out into multiple fields where there is a ~ present - Place these newly split fields into a table (I don't mind if it ends up in a new table or not)
In a situation where I imported an excel file with so many columns and split them into two temp tables and they are linked using a key.
the data has a fixed part lets say
Field1....Field2.....Filed3.....Field4...then Field5.....Field6.....Field7....Field8 is the same data range as Field9...Field10...Field11...Field12. I would want to split this data into multiple rows like this
Field 1 Field2 Field3 Field4 Field5 Field6 Field7 Field8 Field 1 Field2 Field3 Field4 Field9 field10 field11 field12 and so own...
I made a database that in one of the forms, I like by clicking on a button the user be able to select 5 excel files with different file names (in the same directory) and then based on the imported file's names, it be stored in 5 different tables.
At the moment by using the bellow code, I can import multiple files (with the same formats) only into one table . My vba code comes as follow:
Function GetAllFiles() Dim fd As Object Dim strFilter As String Dim lngItems As Long
Const msoFileDialogOpen As Long = 3 Const msoFileDialogViewDetails As Long = 2
A small issue I was wondering of for a few day . Is it possible in SQL query to SELECT multiple fields from multiple tables ? Example for the question is
Code:
dim my_var as String my_var = "SELECT Emp_FName , Emp_LName , Emp_Adress " _ & " FROM Table1 " _ & " AND Emp_Date_Of_Payment , Emp_Sum_Of_Payment " _ & "FROM Table2 " _ & " WHERE Emp_ID = 3 "
Is this code actually valid in SQL gramatics , and is it usable if passed to a Recordset variable ( rs = CurrentDB.OpenRecordset(my_var) ) ? Just FYI - The two tables are not related and I want to keep them that way (If possible relate their records just via SQL/Vba )
I have created an Access 2000 Db, and have gone through the motions of splitting the Db via the Splitting Tool. Since I have done this split, I have added forms, queries, and reports to the Front End. I have left the Back end table structures alone.
This is where my problem comes into play. To enter data into the Db, I use the forms. After splitting the Db, I assumed that the data would be stored in the tables in the BE. An issue had just presented itself and I went into the BE table structure to add a field to a couple of the tables, and when I opened the BE table in the datasheet view, I noticed that there were no records. I then became curious because when I run my reports and queries, the information is present. So I opened the FE tables and what do you know, all the data I have input since the split is housed in the FE tables.
I already attempted to Update the Table Links, but that did not solve the problem, and the data is still in the FE.
Can someone, anyone please help or offer some suggestions on how to resolve this dilemna.
I have access that is required to be accessed by multiple users and register their activities which is reflected with the tables in the background and form sends also the time that they are putting their activities.
So i split the tables and put them in a share folder in one of the PCs. however, the problem is about the timing and dates is not correct usually, and i found out some of the PCs their dates are not on sync. I asked and found out sometimes it is required to change the timing in their PCs.
Therefore, i was wondering instead of fetching the timing from their PCs why not to put the timing of share PC (i.e. timing/Date of the share PC which has the splitted tables)
so can i do like this:
User PC: (Form1) & user activity => Share PC: (Split table) & take time of the share
I've got a table of associate directors "t_ADnames" and want to build separate tables for each AD name that pulls a pass through query from our data warehouse. I'm thinking it's got to be done with a macro somehow? So it would run pass_query where AD name = "John" and insert into t_john, then it would check the next name in t_ADnames and run the same query for say "Mark" and insert all his data into t_mark and so on until the list (of about 12 people) has been completed.
I have a code that allows the user to select the file that they want to import, however it automatically imports the first worksheet into a specific table. Is it possible to change the code to make it import the first worksheet (or with a specific name) into one table and another worksheet into another table?
Code: Dim dlg As FileDialog Set dlg = Application.FileDialog(msoFileDialogFilePicker) With dlg .Title = "Select the Excel file to import" .AllowMultiSelect = False .Filters.Clear
A search form, to search into those tables (It searches by "User")
The search form contains a listbox that shows results (listPC)
And the following code:
Option Compare Database Dim strUserPC As String, strUserTel As String Dim db As DAO.Database, rsUserPC As DAO.Recordset ', rsUserTel As DAO.Recordset Private Sub txtSearch_LostFocus() strUserPC = "" strUserTel = ""
[Code] .....
It works, but I have one problem. It only shows telephones or desktop, not both. It deppends on which line inside UpdateList is first.
That example searches into 2 tables:
-Telephones -Desktops
And searches by "user".
I want to list all telephones and desktops that a user has assigned.
I am wondering if there is an efficient way to compare two fields from one table to another two fields from another table. So basically
Code:
If targetTable.Field1.Value = sourceTable.Field1.Value And targetTable.Field2.Value = sourceTable.Field2.Value Then targetTable.Field3.Value = sourceTable.Field3.Value
The problem is that I need to run this for all entries in targetTable. The only I could think of was to use 2 nested for loops (one for target table and one for source table) as outlined in the following (my data is currently in Excel, but I want to import it to Access)
Code: For i = 2 To 5754 For j = 2 To 3500 If targetSheet.Range("I" & i).Value = sourceSheet.Range("AR" & j).Value And targetSheet.Range("K" & i).Value = sourceSheet.Range("AS" & j).Value Then targetSheet.Range("I" & i).Value = sourceSheet.Range("AT" & j).Value
The above code works but it is really slow (takes about 12 mins on a high-end CPU).
I have a database which is importing several Excel workbooks, each with multiple worksheets. Every workbook has 20 worksheets, with the same 20 worksheet names. When they are imported they come in as one table for each worksheet, named tblWorkSheetName_X with X starting at 1 and increasing for each worksheet brought in with the same name. So if the worksheet names are A-T I have tblA_1 through tblA_6 and likewise for B - T.
I would like to combine all of the tables which come from similar worksheets into one table (one table per name).
I.e. I want to combine the data in tblA_1 through tblA_6 into a singular tbl_A and likewise for tables B through T. So in the end I will have one table for each worksheet name A-T. t how to code this successfully?
I have one Master database and multiple child databases in a folder. Each of these databases (both Parent and Child) have identical table called "source". I need a VBA code which will consolidate tables of child database into the Parent database table.
I have an access form that is used for cash-ups. The cash-ups are not done on a regular basis and the owner requested that the database look at the last cash-up date, current cash-up date and calculate the difference in days and then calculate the average take per day by dividing the total take for the period by the number of days from the last cash-up date to the current cash-up date. This was simple and is done however, what he now wants is to export this data to another table and have it split the total amount per record by the average number of days and reflect the average amount per day over as many lines.
Eg: R5,000.00 / 20 days = R250.00 per day.
This data needs to be displayed in TWENTY lines each with a value of R250.00.
I have a split form with 10-15 fields. Each of these fields is a combo box. The trouble I am having is sorting the data in the datasheet of the split for. I want to sort ascending by "ProductTypeName", then ascending by "Parent SKU" and then ascending by "ProductSizeID".
How can I do this when each of my combo boxes have an ID and then a name? Example below:
I had a list of 1800 full addresses including Postcode on excel, I added 2 columns for Co-ordinates then one column that I use to input data when a call needs removing. I then imported to access table and started to use queries to sort our sales into territories of hopefully no more than 26 calls each, I used the spare column to input a R for removed then only list null entries in queries then I keep adding postcodes in the postcode criteria column until I get around 26 per Query.
My Ultimate goal is to Build multiple Tables of no more than 26 calls that I can geocode onto maps, to make it easier and more cost effective for our sales team.
My Problems are. How do I Prevent Duplicates when entering addresses if new address are entered, I Currently have access creating its own KeyI need to be able to track & prevent duplicate postcodes being assigned to more than one query/Territory table.I need either Access to either Produce a Table Report (As in excel) or might be easier if I just import my data back to excel table.
I kind of think I need new tables for Maps with relationships created between Map table and Territory table. but not sure if this is the best way to go or not.
I am trying to trap the database error "View cannot be updated because modification affects multiple base tables" in the Form OnError event to display a user-friendly message instead of the above.The above can happen in the scenario of inserting/updating several fields of different tables at one time, likewise what I am facing now is the scenario of the user copying an entire record and pasting it.
I tried Case 4405 MsgBox "Can not update the record. it is related to base tables" Response = acDataErrContinue
But it doesn't work. How can I know the case number and solve all the scenarios of multiple insert/update attempts?Also, are there any better solution than this? I first tried to detach the SQL statements out of the views and make it one select statement so that I can normally multiple update/insert(as this problem happens with views only) but since CTE is not supported in Access , I failed to do so.
I have a split database with the backend on our server. When I go to my server and look at all the open files on the network everyone who is in the backend shows up twice. One has zero locks and the other has multiple locks.
I'm working on a database with a form input to record my time on projects at work. How to split End Time - Start Time among all brands that I've chosen for a line item?
I have an Access Database and I want to split up one column into multiple columns. The one column has multiple rows that relate to one person, so for instance I have the following:I am taking information from both tables and I want to create a query but I need to separate out the mother, father, and guardian with the names attached
So from the Child table :
Joe Smith Address Phone
The query that I created is from two tables, the child table and the family table: ( I used the dashes just for it to be easier to read)
First Name--- Last Name--- First Name--- Last Name--- Relationship Joe ----------------Smith ----------Jane --------Doe-------------Mother Joe ----------------Smith ----------John---------Smith---------- Father
So in this scenario I need to get the name of the second parent in another column....meaning have all the parents appear on the same line for this child, and each child there after..
First Name------ Last Name------ First Name------ Last Name------ Relationship------ 2First Name------2Last Name------2Relationship Joe----------------Smith------------ Jane-------------- Doe------------- Mother-----------John---------------- Smith------------ Father
