Max # Rows In A Table
Jun 14, 2007I tried to search for the answer but not luck. I know there is a max size around 2gb for a DB but is there a row limit for a table or is it based upon size?

Adding Rows From A Similar Table To Preexisting Table
Sep 19, 2013I'd like to learn how to do them quickly and effectively in Access. One of those things seems like it would be an incredibly simple, intuitive operation, but it's not, at least not to me.Say I have some data that really should only be on one table, but it's currently on two tables in Access: "List Main" and "List September Adds." They both have the following fields: "Full Name" "Email" "Address" "City" "State" "ZIP" "Phone."
The first table is my main list of contacts. The second contains new info, consisting of 1. a few new contacts, and 2. updated info for a few of the contacts already in table "List Main."
I would simply like to put all the new contacts from "List September Adds" into my "List Main" table, and I'd also like to fill in a few missing e-mails in "List Main" with newly gathered e-mails for those contacts, info that is in my table "List September Adds."I'm sure there is built-in functionality to do something as basic as essentially turning two pages of the same spreadsheet into one. In fact, I know I could import data from an Excel file and have it "append" to a preexisting table if the fields are all the same.
However, I'd like to know how to do it when the tables are already in Access (without having to learn any SQL, mostly because I'm fairly certain I don't need to know SQL to do something like this). I've heard of Append and Update Queries and given their names, it sounds like they'd be useful, maybe with use of "Totals" and "Group By" to get rid of duplicates; however, I can't seem to get any of this to work right.
Mostly, when I think I am doing an Append correctly, it doesn't add new data at the bottom of a table; it just wipes out all the data that was there, and replaces it with data from the source. For instance, when I've been running an Append Query to get my "List September Adds" rows into my "Main List" table, what I end up with is only the "List September Adds" rows, and all the "Main List" rows gone.
Run Out Of Table Rows
Jun 1, 2007The following is for a successful pet grooming business.
I have a Customer Table with a Customer ID as primary key. I have a Pet Name Table with a Pet ID as primary key. One customer can have many pets. The Pet Table is linked to the Customer Table via the Cust ID. I have a Visit Table with an Auto Number for each visit. The Visit Table is linked via the Pet ID number. Each pet can have many visits. That's the problem. We have exceeded the 64,000 rows in the Visit Table. All three linked tables support all the queries, forms and reports. How can I continue beyond 64,000 visits.
Thanks, Jed

Compare Rows In A Table
Nov 14, 2005Hi,
I have a table with four columns - A, B, C, D
I want to compare the values in columns A, B and C in row 1, with the values in row 2 and if they are the same, I want to copy the value that is in column D in row 1 into column D in row 2. I then want to move to the next row in the table and compare the values in row 2 with the values in row 3 in the same way. This will continue for all rows in the table.
Any help would be greatly appreciated as my VB is not up to much.
Thanks in advance
Splitting A Row In A Table Into 2 Or More Rows?
Apr 5, 2012I am working on a project that requires to calculate interest on the amount. There are 2 tables, 1 with Interest rate for a product for different and periods and another is product table with amounts in different period.
Table 1 (Rates table)
Product From To Rate
1111 1/1/2012 1/20/2012 .75
1111 1/20/2012 1/28/2012 .50
1111 1/28/2012 4/6/2012 .40
Table 2 (Product table)
Product From To Amount
1111 1/1/2012 1/17/2012 10000
1111 1/17/2012 1/24/2012 15000
1111 1/24/2012 2/25/2012 20000
What i need to do is to calculate interset based on the above 2 table and insert into another table (Interest). However, the problem is with identifying correct rates for the periods in Table 2.
Eg.
for period 1/1 to 1/17: applicable rate would be .75
for period 1/17 to 1/24: From 1/17 to 1/20 the rate would be .75 and from 1/20 to 1/24 it would be .50
this is what i want to achieve, basically to split the period between 1/17 to 1/24 into 2 so that appropriate rate can be applied.
Cannot See All Rows In Access Table
May 2, 2012My work has a sql server db, and all the tables in our Access db is linked to them for reporting reasons for the secretaries. Why all the rows for one table are not showing up in Access?
I go into SQL Server Management Studio and I can see all the rows, then when I try to go into Access 2010, I cannot see all the rows. I have already updated the table in Access through the Linked Table Manager. However, nothing changes.
86,87,89,113; Strange Jump In Table Rows...
Sep 19, 2006Hokay, so I have a very simple little database which has been written to make my job a little easier by logging the details of certain calls.
Everything on it seems to work fine, but there is one piece of strange behaviour that I just can't fathom...
I currently have 89 records stored (these were ported over from the old Excel table I used to use to log the calls). They imported just fine, and I can manipulate them as required. However, if I go to add a new record the next rwo to be added is 113 for some inexplicable reason. I can still add the record fine, and add subsequent ones as records 114,115,116, etc., but what I don't understand is why Access thinks the record number that comes after 89 is 113!
The table looks - to all intents and purposes - fine; just with its last rows going from 89 to 113 without listing 90-112 in between.
So...um...where are my missing records, and why does Access seem to think that 113 logically follows 89???
Form Populates Two Rows In Table
Mar 13, 2008Anyone know why the following would happen:

Each time I complete the form it creats two records with some data in one row and other data in another row.
How To Delete Duplicated Rows From Table

How Do I Count Number Of Rows In Table...

View 5 Replies View RelatedOnly Updating New Rows In Duplicate Table
Jun 5, 2007Good morning to you all.
I have a problem that I thought would be quite simple......
But 3 days later I am still trying.
I have a form which populates a table by one set of users (Simple enough) they can only add records.
I also have another set of users who want to access that table through a similar form but with a couple of added fields.
They will not be able to change anything only add their comments to what they see in the new fields supplied. Once this has been done it cannot be edited ever.
So I made a "Make Table Query" and added 2 new fields to that, so when I clicked on the query it came me the last update from the previous table. Problem was everything that was added in the extra fields were deleted!!!!
I would like to update the 2nd table with items that have been newly added to the first table, leaving all the items on the second table the way they were!!!!!!!
Anyone got any ideas please
General :: Make One Row In Table A Become Row In B And Rows In C
Nov 7, 2012I have an existing database being used for for order processing (normalized, working). The order table houses the general order info and a separate detail table holds 1 or more orderdetail records for each order in the order table, related by orderID.
A user has asked that I find a way to import her data into the system from an excel spreadsheet. She has individual columns for each type of order detail record, so for each "order" row, there may be 1 or more columns of "orderdetail"s that I will need to parse into the correct tables.
I imported the raw excel into a table, but I need to append that data into the order and orderdetail table rows (i.e. I have to create the order and orderdetail records that match every other record in the system).
It looks like I need to somehow perform a looped INSERT INTO [ORDER] (field1, field2....) VALUE (val1, val2) but there are those related detail records to contend with (the orderdetail table entries) which may be more than one insert....
Test set of data is attached.
Rows Missing From Old Table With No Primary Key?
Sep 11, 2013I have an old table from a database with 2000+ rows deleted and it had no primary key (but it had a number column).
I am splitting another old table which relies on the number column of that old table but I am importing it into a new table with an autonumber primary key which the split table will rely on.
Thing is I need the number and the autonumber to match up accross all records
1 has to be 1
2 has to be 2 and so on
is there a way to "fill" in rows with the missing numbers? i.e. if I have 1,2,3 and 2 is missing the method adds a row "2" to the table.

Totaling The Values In Multiple Rows In A Table
Oct 16, 2006HELP! I’m working for a charity in a small town Tanzania and there is not a soul for miles who knows anything about access.
I have created a database to track requisitions of Office Supplies. I have table full of the requisitions which contains multiple rows for each item we have in the store and the quantity requisition on each occasion.
What I want is a query that will calculate the total quantity of each item requisitioned in a month. Is there an easy way to do this??
Adding/Subtracting Across Adjacent Table Rows
Oct 30, 2006Is it possible to perform calculations across 2 adjacent rows in SQL?
At the moment, I have a running count that tracks the number of updates that go into our database against a specific JobID.
Is it possible to subtract the running count for a previous update from the current update.
For example, I would like my resulting table to end up looking like this
JobID Time Updates Since Last Update
1 10:10:00 1 1
1 10:30:45 3 2
1 11:15:10 9 6
In this example, the Since Last Updates should be found by
subtracting the Updates at 10:10:00 from the Updates at 10:30:45 giving 2 and the Updates at 10:30:45 from 11:15:10 giving 6. It would continue like this for as many rows of data have the same JobID (which could be several hundred!)
What I would then like to do is use the 'Since Last Update' number to display only those updates that are applicable to a certain Time, perhaps using Select Top in SQL.
Am I approaching this from the right direction, or would it perhaps be better to try to do this using Time, as this will always be unique?
Thanks for looking

Combining Rows From Multiple Tables Into A New Table
Nov 21, 2006I have three tables, with the following data (fields separated by "-" here):
Unit - Customer Number - Customer Name - Type of A/R - Total A/R
Unit - Customer Number - Customer Name - Type of A/R - Total Overdue
Unit - Customer Number - Customer Name - Type of A/R - > 90 Day Balance
I would like to combine these tables into one table with the following field names:
Unit - Customer Number - Customer Name - Type of A/R - Balance
When I append the data, it comes out like this:
Unit - Customer Number - Customer Name - Type of A/R - Total A/R - Type of A/R - Total Overdue - Type of A/R - > 90 Day Balance
I would like this new table to include all rows from the original tables, sandwiched on top of each other. As far as I can work it, the Append Query only adds the data as add'l columns; not as add'l rows. I tried changing the field names entirely, so that the final field in each table is called "Balance." However, I still get the same result as above - the columns are added, instead of rows. I swear there's a way to do this, I just can't remember it!
Modules & VBA :: Count Number Of Rows In A Table?
Nov 10, 2014I need to write a code that checks if every 6 lines in a table contains a string. If it contains the string, then carry on looping, but if it does not, it will delete the current line and the previous 6 lines before it. The program should then continue looping through the entire table.
For example,
Code:
Apple
a
b
c
d
e
Apple
f
g
h
i
j
Apple
l
m
n
o
p
q
Apple
.
.
.
I need to find the string "apple" in every 6 lines. So, that means that the first 2 Apples are fine, but for the third one needs to be deleted as it contains 7 lines instead of 6.
Queries :: Transform Table With Multiple Rows To One Row?
Dec 22, 2014I have a table with multiple rows per member that I would like to convert to 1 row per member. I have a table that looks a bit like this:
Member_IDDiagnosis
10000Hypothermia
10000Frost Bite
10001Fatigue
10001Dehydration
10001Exhaustion
99999Exhaustion
99999Hypothermia
And I'd like to convert it to this:
Member_IDDiagnosis - 1Diagnosis - 2Diagnosis - 3Diagnosis - 4
10000 HypothermiaFrost Bite
10001 Fatigue DehydrationExhaustion
99999 Exhaustion Hypothermia
The columns don't line up well but I am looking for each diagnosis to move into one of the 4 columns, depending on whether it is the first, second, third or fourth diagnosis associated with the member.
