How to copy a table(both structure and data) during runtime using java programming.
Looking for equivalent access commands for the following sql commands.
1. create table newemp select * from emp;
2. alter table newemp add userAns int;
3. update newemp set userAns=0;
4. drop table newemp;
I am making an application in Java and I want to use Access as the database.
I wanted to know if I had to handle record access or is this done automatically by Access.
for example, if one user is editing details for an employee and another user wants to access the same record, do I have to write the procedures to ensure that only one user can access this record or will this be hadled automatically by Access.:confused:
Hi all,
I wrote a vba program which I couldnt get to work correctly, so I redid the whole thing in java and now I get the output I'm supposed to get. I'm wondering now if I can execute this java program from a button on my forum in access? and how should I do this if this is possible?
Thanks
What is the proper way to store in a field if I want to store current date AND time as a timestamp. I chose Date/Time as the data type and General Date in the Format. Now I wanted a timestamp whenever a new row is added so I placed =Date() in the default value but it only shows me the date, not the time?
Second question if you know Java: I retrieve this date in a java.sql.date and .toString() shows me the correct result in the default format but when i use the DateFormat.format() method on it, i get a Null Pointer Exception. What could be the problem?
I am working from an existing database which is just two table. The main table has a massive amount of redundancy and duplication and needs splitting into, at first glance, 5 tables.
After I have run my various make table queries and added a Primary Key and FK field to the new tables how do I populate the FK with the Parent PK.
I thought I could simply add all the fields from the new table and then create an adhoc join in an update query to populate the PK to the FK. When I do this however I get "You are about to update 0 records"
I have tried the table analyzer but it doesn't give the correct options to split the table the way I need.
Is there a way to find version number of MS Access using java code.
View 3 Replies View RelatedI am creating a database where I want to have a table that has references to another table.
I have an ID field in both that are linked. I want to be able to on creation of a new record in this new table have it grab the ID field from the other table.
I am trying to help a new employee with an MS Access 2000 problem. The db was created years ago, and the main table (permits) needed some major changes. She created a new db with a table that has all the same fields as the old db, but many new ones as well. We want to now import the data from the old db's "Permit" table to the new db's "Permit" table. All the field names are correct, but we keep getting errors trying to import and export. There are approximately 940 records.
Is there an easy way to do this? Thank you!

hi
I am trying to copy the data from one table into another table. I then wanted to update the table where it is copied from. This data i then wanted copied into that table in another row.
Any ideas?
Hi,
I am trying to copy the contents of a table with 11 fields into a new table which is the same except for an additional two fields at the end.
Any advice would be appreciated..
Thanks..
Is there a way to create a new independent table from the structure of an existing table? I want to create the same table with no records and place it in a separate folder
Thanks in advance for your help.
Hi:
I am looking for some guidance in doing the following:
I have a tableO that contains a list of objects that have associated attributes, specifically a list of system_names (object) and the associated attributes (additional fields in the table) that include port_name, port_direction. Think of each one of the records as a template that will supply data to another table, called the Instance table (tableI). The concept is that the user can populate the template with various objects and associated ports, and direction.
The table cols are;
PK|FK|system_name|port_name|port_direction|
The data for this table is manually entered via an associated form.
At some later time, the user want to make a copy of an object(e.g. a record in tableO) by populating Table I (the instance table). The first few fields of tableI are named identical to tableO. Table I contains additional fields that further refine the template, by adding a object_property field, and a port_direction_property field.
Table I looks like:
PK|FK|system_name|port_name|port_direction|prop1|p rop2
The forms interface allows the user to fill in the fields in the TableI (intance table) directly, or, lets the user scroll through the list of objects in the template table, and chose a template, copy the fields:system_name|port_name|port_direction into the same fields in table I, and then add values to prop1 and prop 2 manually.
I made the combo box control that will list the objects from the object column of the template table (table O) and make the desired selection. I have a radio button adjacent to the combo box that when clicked, will copy the selected record and designated fields from the template object table (tableO), into the same fields of the instance table (table I). The instance table is displayed on an adjacent form.
After the fields are copied to the instance table, the user can type in the data into the additional fields (e.g. prop_1, prop_2), and complete the record.
I do not know how I can do the 'copy' from tableO to table I when the radio button is pushed. I know to allow an action when the radiobutton is 'clicked'. Table O and tableI are not currently related.
Can you provide some guidance?
Thanks a lot for your time

Hi,
I'm looking to include a button on a form that opens a new entry in another table and copies some field entries from the first table into the second table. I tried an append query, but it seems to be unable to be displayed in a form. I just want to copy data from one form to another. Thanks.
Hello,
Is it possible for a [MSAccess] query to obtain table data from an [external] ODBC Datasource?
Something like:
INSERT INTO TableA SELECT * FROM ODBC;DSN=MyDSN;UID=;PWD=;.TableA
I found a similar thread but didn't understand the answer which mentioned linking a back-end to the Access Table.
Cheers.
Ok so here is the problem I need help with,
I have a prices table that stores all the different price changes for each part I have in my Parts table what I need to figure out how to do is to copy the "Last" price for that part from the price table into the Price field of the Parts table or have some way of updating it automatically either by macro or what not - example:
Price Table:
PriceID (PKey)
PartID (Connected to Part Number ID)
Price
Price Added( Date & Time when price was added so I can groupby "Last" or "Max" in the Price Query I have made)
------------------------
Parts Table:
PartID (Pkey)
Part Number
Price
-------------
Now how do I take the value my Price query gives me for "Last" or "Max" Price using the last date for that parts price and have it automatically get copied into the Parts Table price?
Thanx
I am looking to copy one exceptionally large table to another. I can use VBA to copy the entire Report2013.accdb to Report.accdb while compacting at the same time. This is very fast and works well. However once it's copied I need to rename the table tblReport2013 to tblReport. None of these table are in the accdb that I am running the scripts from FrontEnd.accdb. I am working very hard to keep the data tables under the 2 GB limit, which is why linking and keeping the data separate is necessary. There is the chance that Report2013 will be on the network while tblReport will be local to the user, and may or may not be a subset of the Report2013.
I have considered a number of options:
DoCmd.Rename - I can't seem to tell it a database location
I could try
docmd.copyobject - and see if it keeps the file size the same or smaller then the original.
I could just write the sql statement and copy the data that way, and compact the table afterwards. The trouble with doing the transfer that way is hitting the 2GB limit, before I can compact/compress the newly imported data.It just seems odd to have to find another solution when all I really want to to rename a table and ensure the new new is still linked as a separate table.
I want to be able to copy the data within a selected field and then place it into a fresh database is this easily done?
my second questions is i have several fields which need to be merged into one 'Address' field as currently i have data with Building Name, Number, Line1, Line2, Line3, County, Town, Country. This is required to be merged into one field how would i do this?
Not all fields have data is there a way to put a space between each of the current fields when merged as well?
Query:
I have two tables : Table1,Table2.
Table1 has columns : A,B
Table2 has columns: A,C
What I want to do is to copy all data of "C" from Table2 to Table1 so that Table1 has columns: A,B,C..(Column "A" is common in both Tables).
I am using Access 2007 and would like to know how to copy column names from one table to another. I am importing data from excel and the column names come out as 'Field 1', 'Field 2', etc. I went through the trouble of manually renaming the column names of one of the tables (22 columns in all). I will be importing/creating 55 new access tables and don't want to have to manually rename all of these columns. All of the columns in all of the tables will be exactly the same, so I was hoping that after I did this once, I could copy the column names to the other 54 tables.
View 1 Replies View RelatedI have two identical access databases. I copied the master file to my desktop to work on it while someone else was in the shared file. I edited about a hundred rows in the Data Entry table (the records exist in both files), and now I want to copy those changes back over to the master file without messing up any of the other data. I'm not sure what the other people changed in the file, I just know what records I have that need to be copied over. Again, they exist in both files, I just want to overwrite the records in the other file with my updated records without affecting other data.
View 5 Replies View Relatedis there an easy way to copy the current record on a form when clicking a command button such that a snapshot of that record is copied to a table for archiving purposes?
the table has about 120 columns so it is cumbersome to write an Insert Into sql statement within VBA code.
what i am attempting should be quite straightforward...i just want to take the current record in its entirety that is from a single table and append it to another table of the same structure.
any help would be appreciated!
I have linked a SQL table to my ms access database. In order to view the SQL table as read-only and still be able to update the access table I have setup a form with a subform.
I know it would be a dublication of data but is there a way thru code of copying the data on the subform to my access table. I was hoping I could put a button on the form that would copy this data. My idea is after the copy is done all the information I need will be in my access table. I'm new to this linking idea and am worried I will only have half the information I need if the link breaks etc.
Thanks
I'm using Access 2007.I have 2 tables that are identical in structure.The tables are called [Workorder Parts] and [Workorder Parts Temp]. They both have the same structure:
WorkOrderPartID (Autonumber)
WorkorderID(Number)
PartID(Number)
Quantity(Number)
UnitPrice(Currency)
Notes(Memo)
KitID(Number).
[Workorder Parts] has 128 records in in and [Workorder Parts Temp] has 28 records in it that are a small subset of [Workorder Parts] therefore, the contents of the key field column in [Workorder Parts Temp] is the same as in [Workorder Parts].I tried the following SQL but get an error message saying "Cannot Update "WorkOrderPartID" Field not updateable":
DoCmd.RunSQL "INSERT INTO [WorkOrder Parts] SELECT * FROM [Workorder Parts Temp]"
My aim is that I want all of the records from [Workorder Parts Temp]to be copied to [Workorder Parts] and have their "WorkOrderPartID" fields correctly updated with a new value...
I have two tables. TableA and TableB They both have the same columns.
I need a query that will look at the diferences between TableA.Column1 and TableB.Column1 and copy whatever TableB.Column1 is missing from TableA.Column1
So I want it to copy over the entire record based on what TableA.Column1 has the TableB.Column1 does not have.
I have two tables, table A and table B. Table A is a master table where it contains various values. I want to do it such that if user keyed in value X and value Y into Form B (linked to table B), it will check Table A for value X and value Y. If the values matched, it will display a new value (value Z) that is taken from Table A into Form B.
If IsNull(Me.txtValueX) Then
MsgBox "Please type Value X", vbInformation, "Value X Required"
Me.txtValueX.SetFocus
ElseIf IsNull(Me.txtValueY) Then
MsgBox "Please type Value Y", vbInformation, "Value Y Required"
Me.txtValueY.SetFocus
[Code]...
I am stuck at this part where i am not sure how to retrieve value C out.
It basically is used to create, manage and track Customers, Parts, Work Orders and Suppliers, payments and employees.You simply create a Customer and then create a Work order that contains a list of parts and labour items.
What I want to do is to create a "Kit" of parts so that the user does not have to select each part individually when they create a Work Order. For example, if I use a mechanics workshop as an example, the mechanic may sell his "Signature 1916cc Engine" that consists of 40 different parts and some other items such as labour and other services. In this scenario, instead of the user individually selecting 40 different parts, all he needs to do is select the Kit called "Signature 1916 cc Engine" from a drop down list and all of the 40 parts and other items would automatically populate the correct Work Order Parts/Labour tables.
I would also like the user to be able to select another "kit" that would either replace all parts and labour records or append to what is already there.
I have changed the form called "Workorders" to have 2 buttons. One called "Load Kit" the other called "Save Kit".If the user presses "load Kit" a form will be displayed that enables them to select a "kit" from a list and whether they want to replace all of the existing parts and labour records or if they want to append to the existing records.
In order to create a new kit, the user can simply manually create a new work order by individually selecting each part and labour item and then pressing the "Save Kit" button. The user will then be asked to provide the short name of the Kit and the long description (I have created table called tKit). The new kit will then be saved.
It appears that the "Entered by" field that is linked to the Employee table must not be blank other wise the Workbook is NOT saved....I have tried to figure out why this is happening but can't!
The Work Order Parts are stored in "Work Order Parts" and the Work Order Labor is stored in a table called "Work Order Labor". I have created 2 extra tables called "tKitWorkOrderParts" and "tKitWorkOrderLabor" that I assume will contain the items that make up the kits..
