How I can delete all rows from my table whit on query? Also I want that when I delete rows from my table index and other settings will stay in table.
Hi
I have to make a query which deletes duplicate rows from my table. How I should start to make it? Can I do it whit one query or does this operation needs more queries? I know that DISTINCT works but how I can set it to DELETE operation?
I have try to use command DELETE DUPLICATES FROM Table; but this command deletes all rows from table why?
A SELECT works:
SELECT *
from mastertable
INNER JOIN secondarytable
ON mastertable.Identicalfield = secondarytable.Identicalfield
But none of these do:
DELETE
FROM mastertable
INNER JOIN secondarytable
ON mastertable.Identicalfield = secondarytable.Identicalfield
**Incorrect syntax near the keyword 'INNER'.**
DELETE
FROM mastertable JOIN secondarytable
ON (mastertable.Identicalfield = secondarytable.Identicalfield)
**Incorrect syntax near the keyword 'JOIN'.**
DELETE
FROM mastertable
WHERE (mastertable.Identicalfield = secondarytable.Identicalfield)
**The column prefix 'secondarytable' does not match with a table name or alias name used in the query.**
DELETE
FROM mastertable
WHERE IN (SELECT *
FROM secondarytable)
**Incorrect syntax near the keyword 'IN'.**
Can anyone help? This should be easy, shouldn't it?!
Thank you.
I need to append some rows into a table, before I add these rows i need to delete all of the old rows.
I can't use a Make Table query because I am updating a linked table in another database.
So how can I (automatically) delete all rows in that table before or during the append process.
Thanks

I have a list of projects and am creating a query that tells me their duration based on beginning and ending dates. These beginning and ending dates can be edited by the user, and frequently, there are multiple beginning dates. When I query the projects, instead of getting unique project numbers on the left hand side to create unique rows, I get many of the same projects with different start dates. I would like to use the FIRST start date only for every project and not have multiple rows with the same projects being counted multiple times.
Is there any way to delete the excess rows and keep the original row? I've read a lot about using DISTINCT and UNIQUE INDEX with SQL but it seems as though these are only available for tables and not queries. Bright ideas, anyone?
Is there a way to select several rows of records in a datasheet view of a table and delete all of the selected records?
Every time I try to delete more than one record at a time, I get the following message: "The Micorsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time."
Then it will let me delete one record out of the selection.
I am the only one in that particular table at the time I am trying to delete the record.
Thanks in advance for your help...
Hi
I need to know if it is possible to create a delete query which will target particular fields in a row based on certain criteria in a seperate combo box(on same table).
The few ways that I have tried to do this have been unsuccesful so if anyone can shed some light on the subject it would be greatly appreciated.
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...
What is the best approach?
I am trying to assign teams to players. I have an import table with all of the players information listed. What I want to do is determine the count of players in a given city. For every 9 players I want to add a new record to the Team table and assign the team number (auto incremented for each team created). Then I want to add the players to the Players table with the Team Number that was created.

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.
I have a form with a sub form. when a record is choosen in a combo box the sub form is filled out with a record.
what I am trying to do is have a button that will copy that record to a history table then delete it off the the main table.
I cheated by using the wizard to get the code to delete the record but I am having troubles modifying the code to copy that record to the history table. Here is the code below. I have tried to insert code in several places but it just errors out.
'------------------------------------------------------------
' Master_tbl_sub_fm

'------------------------------------------------------------
Function Master_tbl_sub_fm()
On Error GoTo Master_tbl_sub_fm_Err
With CodeContextObject
On Error Resume Next

i have two data tables, one is depending on the other. now i need to delete the main table row depending on the subtable row if it is null.

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.

I 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?
View 4 Replies View RelatedI have a table which lists amendments (amendments history file) which need to take effect of another table (M0070), I can select the records fine and so the sub query looks to be okay but I'm missing something (probably obvious) in the deletion query where by it does only delete the records selected but everything (I know that the asterisk is wrong in the code below but I'm not sure what to replace it with).
At this point I'm trying to delete all records for a specific employee on a specific contract (they can be 1 or more employee records for that individual on a contract - and they could exist on multiple contracts).

I have an employee and asset database. If an employee gets fired, I need remove them from the general employee records, but I want to save a record of that employee. Is there a way to delete an employee from one table and have it automatically added to another table?

Hi,
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
I 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.
My 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.
Hokay, 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???
Anyone know why the following would happen:
I have a form that is linked to a single table. For some reason some controls populate one line in the form and others populate another line.
Each time I complete the form it creats two records with some data in one row and other data in another row.
I need to do a count of the total number of rows in a table or query. Say I have a table with 7 records, I want to be able to get total number of rows instead of the sum of the row and save it to some other table.

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
I 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.
I 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.
