I have a table in an offline form bound to an SQL statement.

I want the user to touch a row in that table and display another offline form based on the selected rows content.

I an online for I would set event parameters on the table load and retrieve them in the event handler.

I cannot find an example of this in the tutorials.

Is this possible?

What about Offline work with photos offline - LREX0307 /LREX0308
The detailer LREX0308 can access all the values for the current row that the user touched in LREX0307


* This example demonstrates a useful technique for handling List - Detailer programs (when Offline).
* This List program is able to call a Detailer offline program and give that program access to all the SQL FLD values available in this program, without any coding.

Or

Work with Order Headers LREX0321 / LREX0322

Or

Read an SQL FLD in a Script LREX0340 / LREX0341 (Under Other examples --> Advanced Examples --> How To -->Read an SQL FLD in a script )

Thank you - I didn't make the mental leap from what was explained and what I was trying to do!

I have implemented the technique and I can see it is working. I am having trouble using FLD value in an SQL binding.

The following

#Com_Owner.Set_TextBox Name(STUDYR) Layout_Row(1) Layout_Col(1)
#Com_Owner.Set_Binding Name(STUDYR) Property(VALUE) Bindtotype(FLD) Bindto('STUDYR')

Displays the value I expect (10, 11 or 12)

But

#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(SQL) Bindto('SELECT ROWID, STDID, CALYR, STUDYR, CRSID, STDMSI, SCHID, SCHLNM, CRSLNM FROM StudentCourses WHERE STDID = &(GVAR:BOS_SO000_STDID_CT) AND STUDYR=&(FLD:STUDYR)')

Produces no output and no errors.

If I remove the STUDYR= clause I get a full listing with 10, 11 and 12 values.

A previous version using a GVAR to supply the value worked as expected,

Is this syntax incorrect for SQL use?

I think the syntax is ok, but in the SQL, when referring to a FLD STUDYR that is not in the SQL table being bound to the element, you have to explicitly specify which SQL table is being used.

e.g. (from LREX0322)

* Note that because this element is bound to the OrderLine SQL Table, if we want to refer to a FLD from the OrderHeader SQL Table, we have to refer to the FLD as &(FLD:OrderHeader.HeaderNumber)

#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(TBL) Bindto('OrderLine')
#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(SQL) Bindto('SELECT ROWID,OrderNumber, OrderLine, ProductID, OrderLineValue, OrderLineQuantity, OrderLineStatus FROM OrderLine WHERE &(FLD:OrderHeader.HeaderNumber) = OrderNumber ')

Mark

I have changed the code to

#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(SQL) Bindto('SELECT ROWID, STDID, CALYR, STUDYR, CRSID, STDMSI, SCHID, SCHLNM, CRSLNM FROM StudentCourses WHERE STDID = &(GVAR:BOS_SO000_STDID_CT) AND STUDYR=&(FLD:StudentEntries.STUDYR)')

as suggested but it still does not work. Some observations.

1.The STUDYR value does work for the TEXTBOX binding.

2. Using the StudentEntries.STUDYR version in the TEXBOX binding causes a crash (developer console).

3. If I change SQL binding to, say, StudentEntries.STUDYRX (doesn't exist) there is no error thrown. So there could be a problem but no way of knowing what it is.

Any ideas?

Looking at Order Headers / Order Lines (LREX0321 /LREX0322), as a working example (I'm assuming it does work in your environment)

The key things are:

The calling program (Order Headers) LREX0321 does this:

* Note OrderNumber is passed as HeaderNumber
#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(TBL) Bindto('OrderHeader')
#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(SQL) Bindto('SELECT ROWID,OrderNumber, OrderNumber AS HeaderNumber, CustomerID, OrderValue, OrderStatus FROM OrderHeader')
...

#Com_Owner.Set_Op_Form_Open Event(BOUND_TABLE.COL%7.CONTENT.OnClick) Name(LREX0322) Presentmode('Stack')


The called program (Order Lines) LREX0322 does this:

#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(TBL) Bindto('OrderLine')
#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(SQL) Bindto('SELECT ROWID,OrderNumber, OrderLine, ProductID, OrderLineValue, OrderLineQuantity, OrderLineStatus FROM OrderLine WHERE &(FLD:OrderHeader.HeaderNumber) = OrderNumber ')




1. The call (set_Op_Form_Open) must use PresentMode('Stack') if the called program is to be able to access FLDs from the parent (caller) program.
2. The SQL Table name in &(FLD:OrderHeader.HeaderNumber) is the name in the parent's context - i.e. from this line in the parent:

#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(TBL) Bindto('OrderHeader')

Are both those true in your example?

I've got this working and it was my mistake (as I'm sure you guessed). I had the wrong value in TBL binding (didn't match the SQL).

#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(TBL) Bindto('StudentCourses')
#Com_Owner.Set_Binding Name(BOUND_TABLE) Property(ROWLIST) Bindtotype(SQL) Bindto('SELECT... StudentCourses...)

I must admit though that I don't understand this syntax - it looks like we're giving a single property of an object two values?
