Modifying table entries from LibreOffice Base, pos

问题:

I've successfully connected LibreOffice Base with MySQL data base server. I've tested if I modify my table from host (free hosting service on internet) then the changes are reflected when refreshing the table object in LO Base. But my question is, can I modify DB table directly from LO Base? I guess that it's possible using sql queries from LO Base, but how? Please give me some insights or tutorials. Thanks.

The normal way to alter a table:

1. Tools -> SQL
2. Enter an ALTER TABLE command and press Execute button.

A way that works, even though it complains that no result set is returned:

1. Create a query in SQL view.
2. Enter ALTER TABLE command.
3. Click button in toolbar to mark it as Run SQL command directly. Or Edit -> Run SQL command directly.
4. Close the query and double-click to run it.

My guess is it could be done with a macro as well, similar to https://forum.openoffice.org/en/forum/viewtopic.php?f=5&t=75763 but using ALTER TABLE.

EDIT:

Inserting new row data in a form is easier than altering the table. First, make sure this works:

1. Double-click on your table under Tables.
2. Insert -> Record, or enter data in the last new row.

If Insert -> Record is disabled, then you need to set up the table for editing. Make sure that your connection to the database allows editing. Also the table must have a primary key.

Once you can insert records in Table view, it's time to create the form:

1. Under Forms, Use Wizard to Create Form.
2. Select your table and press >> to include all fields.
3. Click Finish.

Now you should be able to open the form and enter data into the final new row.
