Libre Office Base: Unable to change or save records in form - libreoffice

I am working with LibreOffice Base and I've made a form to insert data in my table, but when I open this form ( not in Design-mode, just right-mouse click and select 'Open' ), I am able to view the existing records, but I am not able to change and save the records.
Am I doing something wrong?
Thanks for your time!

Tables in LibreOffice Base need a primary key. Only then you can change and save records.

Access Select specific tables to update, change and modify

I create a DB where each table is a different project.
However, i am not sure how i would go about creating a form in which a user can choose a specific table (project) from a drop down menu and than be able to update/edit/modify the contents in the table.
Each table is standardized to contain exact column headers.
Thanks in advance for you help.

Some fields are missing in the fieldexplorer. How to show all fields?

i'm using Crystal Reports with my ERP-System. There have been predefined reports i now want to change.
In the field-explorer are some tables which have been renamed for better readability. But those tables are missing some fields, i want to use. If i connect the whole table again, all fields are there. Is there a way to display all fields in the predefined tables.
I tried to refresh the Database but nothing changes. If i delete the predefined table and then rename the new one to the old one, so i can use all predefinded formulas, all used fields in the report get deleted. I would need to recreate the whole report then.
Thanks for the help
If it is truly the same table and is not showing all the fields then you need to do "Database > Verify Database". That will force CR to refresh the structure of the table (instead of just the data). If this doesn't add the missing fields then the table in the report is actually a different object.
To see what the table/view the report is actually using go to "Database > Set DataSource Location" and look at the properties node for that table. It will show if it is a table/view/SP and what the true object name is.
If you want to replace the existing table with a different table you go to "Database > Set DataSource Location" again. Highlight the existing table in the top window, connect and highlight the replacement table in the bottom window. Then click update. Crystal will replace one table with the other and all of the fields in the report that exist in the new table will be mapped automatically. Note that the new table will keep the alias of the original table. If you are unsure if the table was updated you can look at the properties node in the top window to see the change.

ms access unbound datasheet or alternative control

I want to have an unbound datasheet control in ms access forms or any other alternative tabular data showing control, where I can add rows dynamically and save it to database on form submission not on each next row.
I tried bound datasheet but it saves records as new rows is created, is there some property or method which prevent record saving automatically.
or any other alternative.
below is snap (red portion is not created, I want like this).
actually I want to save order
which has child table order_details
for order details I want this control
No, the records have to exist somewhere.
Use a temp table where you create 10 or so empty records before opening the form, and delete all records when you close the form.

Cannot see records in form bounded to table in Access

I have a form and it's record source is a table. I created the form separately and added the control sources to the different fields in the form and also changed it's record source. I imported values from an excel sheet into the table and when I open the form, I do not see the tabe values being displayed in the form. Any idea what I should do to see the table records in the form?
In form design mode, check the form's DataEntry property. It sounds like yours is set to Yes, which hides existing records and only allows new entries. Change it to No and you will see the existing records.
Another possibility is that a filter is active and no records match that filter.
Use a form wizard to generate a working form based on your table. Then once you can see the data being displayed in the form, customise as needed.

Autonumbering in forms in Access

I have a form in access that saves the data in a database and I want one of the fields to be automatically calculated as the next value in line as the ID so that the user doesnt write the ID. does anyone have any ideas?
Create your table using an Autonumber data type.
If you manually create your tables then this statement
CREATE TABLE TableThatIncrements
(
Id AUTOINCREMENT(1001,1)
)
Alternately you can edit your existing table Id column using:
ALTER TABLE TableThatIncrements
ALTER COLUMN Id AUTOINCREMENT(1001,1)
If you do not, then you can change per the article I mentioned via the GUI interface. See steps in this article: https://superuser.com/questions/288087/how-do-i-set-the-first-value-of-autonumber-in-access
You can run a query in Access by doing the following:
Go to the "Create" tab and click "Query Design"
Just close the window that appears which asks you to select tables, we don't need that.
Go to the "Design" tab and click the button with the arrow until you get a textual input screen. (By default, it says SELECT;).
Delete the default text and paste the above query.
Click "Run".
