00:00 | Welcome to the Spoken tutorial on LibreOffice Base. |
00:04 | In this tutorial, we will learn how to |
00:07 | create a Subform. |
00:09 | For this, let us continue with our familiar Library database example. |
00:15 | And we will consider the following case: |
00:18 | * How can we list all the members of the library? |
00:22 | * And for each member, how can we see only those books that have not yet been returned by that member? |
00:31 | One way is to create a form listing all the members in the library. |
00:36 | And then creating a subform below it, to list those books that have not yet been returned by the member. |
00:44 | Once we design this form, we will be able to update the form. |
00:49 | For example, when a member returns a book, we can update this information. |
00:55 | And, here is a sample screenshot of the form we will design. |
01:01 | Notice, it also shows a subform at the bottom. |
01:06 | Let's open our Library database. |
01:09 | In our previous tutorials, we created the ‘History of Books Issued to Members’ query. |
01:17 | Now we will use this query and the Members table as the base for creating our new form. |
01:25 | Let us first copy this query by right-clicking on the query name and then let us click on Paste. |
01:34 | In the pop-up window for query name, let us type in a new name: ‘Books Not Returned’ |
01:42 | Let us now open the ‘Books Not Returned’ query in edit mode. |
01:48 | In the Query Design window, let us add a criterion to show only those books that are not checked-in. |
01:58 | For this, let us type ‘equals 0’ in the Criterion column, under CheckedIn. |
02:06 | And press Enter. |
02:09 | Let us now save the query and close the window. |
02:13 | In the main Base window, let us click on the Forms icon on the left panel. |
02:20 | And then click on the ‘Use Wizard to create Form’ option. |
02:25 | Now we see the familiar Form wizard. |
02:28 | Let us go through the 8 steps on the left to create our form. |
02:34 | In step 1. field selection, let us choose Table: Members. |
02:40 | Then let us move all the fields to the right side. |
02:46 | And let us click on the Next button. |
02:49 | We are in Step 2. Setup a subform. |
02:54 | So here, let us check the ‘Add subform’ check-box |
02:59 | and click on the option: ‘Subform based on manual selection of fields’. |
03:07 | Let us go to Step 3. Add subform fields. |
03:11 | Here we will call our new query which we designed a few minutes ago. |
03:18 | So, let us choose ‘Query: Books Not Returned’ from the Tables or Queries drop-down. |
03:26 | And we will move selected fields from the available list to the right side as shown on the screen. <pause> |
03:37 | Click on Next. |
03:39 | Step 4. Get joined fields. |
03:43 | Here we will choose the MemberId field from the top two drop-downs, as this is the only relating field. |
03:53 | And click on the Next button. |
03:57 | Step 5. Arrange Controls. |
04:00 | Here, we will choose the third option- Data sheet, for both the form and the subform. |
04:08 | And click on the Next button. |
04:11 | Step 6. Set data entry. |
04:15 | Here, we will leave the options as they are and click on Next. |
04:22 | Step 7. Apply Styles. |
04:26 | Let us choose Grey as the form background. |
04:29 | And go to the final step. |
04:32 | Step 8. Set Name. |
04:36 | Here, let us give a descriptive name to our form: ‘Members Who Need to Return Books’. |
04:45 | And let us click on the Modify form option, as we are going to do some more changes. |
04:53 | Now let's click on the Finish button. |
04:56 | In the Form Design window, notice that there are two tabular data sheet areas. |
05:04 | The one above is called the form and the one below is called the subform. |
05:11 | Now, let us add a label above the form. |
05:15 | We will click on the Label icon in the Form Controls toolbar at the top and draw it on the form. |
05:25 | Double clicking on the label, brings up its properties. |
05:31 | Here we will type ‘Members of the Library’ against label |
05:37 | and change the font style to Arial, Bold and Size 12. <pause> |
05:47 | Similarly, let us add a second label above the subform as shown on the screen |
05:55 | and call it ‘List of Books to be returned by the member’. <pause> |
06:00 | Next, let us shorten the form’s length as shown on the screen. |
06:07 | And then let us increase the length of the Name field in the form. <pause> |
06:13 | Similarly, let us lengthen the Book title field in the subform.
<pause> |
06:21 | Let us change the fonts here to Arial, Bold and Size 8. |
06:28 | And change the background color to white for the form and Blue 8 for the subform. <pause> |
06:37 | Next, let us hide the MemberId column by right-clicking on it and choosing the Hide column option. |
06:47 | Okay, we are done. So, let us save the form design and test it. |
06:54 | In the main Base window, let us open the ‘Members Who Need to Return Books’ form by double-clicking on it. |
07:03 | There is the form. |
07:05 | Let us browse through the members by either using the up or down arrow keys, |
07:12 | or by simply clicking on the various member names. |
07:16 | Notice that the subform below refreshes and shows books to be returned. |
07:23 | In the subform, let us choose any record |
07:27 | and let us type in ‘12/7/11’ in the actual return date field and check the CheckedIn field |
07:41 | and press Enter. |
07:45 | Let us now refresh the form by clicking on the Refresh icon in the Form Navigation toolbar at the bottom. |
07:56 | Notice that the record we just edited is no longer listed here |
08:02 | which means the book has been returned or checked-in. |
08:07 | So, there is our form with a subform. |
08:11 | This brings us to the end of this tutorial on Subforms in LibreOffice Base. |
08:17 | To summarize, we learned how to: |
08:20 | create a Subform. |
