Re: [libreoffice-users] SQL statement error when linking Main form to SubForm

Hi Dan,

My form displays a Church Membership Roll -

- The Families Table contains the family's Surname, Address, Street Map
Reference, Date Loaded, Date Last Updated etc.
- The Roll Table has a separate line for each family member.  It includes
First Name, Title, Date of Birth, Membership Status, Occupation etc.

On the form the family fields are displayed in Columnar format with labels
left.  The Roll fields are in a Data sheet.

When I call up a family I want all the family members to automatically
appear, and I was hoping to do that using Main form / Sub Form linking.

At the moment, by removing the linking, I can get all of the Roll table
rows appearing in the Data sheet, so I think I'll write a macro to filter
the rows to include only those associated with the currently displayed
family.  I think this would work just as well as the linking mechanism, but
can you think of a better solution?

Thanks,

Noel

     It seems that this has been a problem since 2010 with OpenOffice.org
Base, so it is likely a problem with LibreOffice Base as well.
     This link describes how one person solved it.

     There is something more that I would like to know:
 1) What purposes do this form and subform serve? (Specifically, why use
the parameter?)
2) How does the design of the form accomplish these purposes?

Hi Dan,

Thank you for your prompt and detailed reply.

I'm using the H2 database and I suspect that was the vital piece of
information that I failed to mention in my first post.  Sorry about that.

I originally linked the two tables using the Wizard. Then later I used the
Form properties dialog to un-link and then relink them, but to no avail.

When I got your reply, I created a new test Form going through all the
steps you laid out, but I got the same error message as before.

I then went to Queries | 'Create Query in SQL view' and ran this query -

SELECT * FROM "LUCROLLS"."PUBLIC"."Roll"
WHERE ("FamilyKey" = :link_from_FamilyID)

With the SQL button on, (Run SQL command directly), I got the same error.
With the button off I got a prompt to manually enter the value of
':link_from_FamilyID'.  Entering a 1 produced the same error as before.

I finally tried the query in a native, (HSQL not H2) database, (I changed
the table name to suit the other database), and when I manually entered a
suitable integer it worked!

So my conclusion is that setting Table links in a Base Form doesn't work
when using H2 as the database.  Is that right?

Thanks again for all your help - much appreciated.

Hi,

I have a Form with families info in the Main Form and family members
info
in a Sub Form. The Tables and relevant fields are -
Main Form (Families)
FamilyID     BIGINT     IDENTITY
<Info fields follow>

Sub Form (Roll)
RollID         BIGINT     IDENTITY
FamilyKey  BIGINT
<Info fields follow>

I have linked the forms using fields FamilyID and FamilyKey - a one to
many
link.  However I get the error -
The data content could not be loaded.
SQL Statement:
SELECT * FROM "LUCROLLS"."PUBLIC"."Roll"
WHERE ("FamilyKey" = :[*]link_from_FamilyID) [42001-139]

The problem seems to be the 'link_from_FamilyID' phrase.  I Googled
42001,
and all it says is that it is an invalid SQL Statement, but I don't know
what is wrong.  Even if I did, the SQL statement is generated by the
Wizard!  Is there a way of manually over riding the Wizard?  Failing
that
I'll need to write a macro to filter the Roll records to achieve what I
want to happen.  But I shouldn't need to do this.  In another
application
I
have previously got this sort of linking to work.

Can anybody see what I am doing wrong here?

I'm running LO version 3.5.6.2 and Windows 7.

Thanks,

Noel

       Needed information: How did you link these two tables? (Specific

steps please.) Are you using Base as the front end to another database?
Where did Base get the name "LUCROLLS"? (I know that "PUBLIC" is the
schema
and 'Roll" is the table name.) Is "LUCROLLS" the name of the database
perhaps?
      I created a database with two tables: Families and Roll. Families
was
given the primary key, FamilyID (BIGINT). Roll was given two fields:
RollID
(primary key, BIGINT), and FamilyKey (BIGINT). Using the Form Wizard, I
created a form with Families as the main form and Roll as the subform.
Step
2: (Setup sub form) Clicked "Add subform" box. Clicked Next. Step 3: (Add
subform fields) Selected "Table:Roll" from the Tables or queries
drop-down
list. Clicked the double right arrow to move all the fields from the
table,
Roll, to the "Fields in form" list. Clicked Next. Step 4: (Get joined
fields) Select FamilyKey from the "First joined subform field" drop-down
list. Select FamilyID from the "First joined main form field" drop-down
list. Click Next. I then went through the rest of the steps of the Form
Wizard.
      Possible way to correct the situation: Edit the form.
Add the Form Controls toolbar. (View > Toolbars > Form Controls) The
fourth icon from the left is the Form tool (icon). But first control
click
the FamilyKey field. Then click the Form tool. (The Form properties
dialog
opens.) Click the Data tab. Click the ellipse (...) for "Link master
fields". (The "Linked fields" dialog opens.) Select FamilyKey from the
top
Roll drop-down list. Select FamilyID from the Families drop-down list.
Click OK. Close the Form Properties dialog. Save the Form. Save the
database.
