Check for duplicate IDs in SQL db from form input

Posted on by Community Power Pla... Microsoft Employee

I want to only patch the data if 'txt_sp_id' (form) is not found in Speaker:sp_id

ForAll(Speaker,
If (sp_id <> Value(txt_sp_id.Text),
Patch(
Speaker,
LookUp(Speaker, sp_id=Speaker[@sp_id]),
{
sp_id: Value(txt_sp_id.Text),
sp_name: txt_sp_name.Text,
sp_email: txt_sp_email.Text
}
)));

So far, I am getting this error: This function cannot operate on the same data source that is used in ForAll.

Hi @Anonymous ,

I am not sure of your data model here, but the below will update the Table for every value not equalling the Text Box value

UpdateIf( Speaker, sp_id <> Value(txt_sp_id.Text), { sp_id: Value(txt_sp_id.Text), sp_name: txt_sp_name.Text, sp_email: txt_sp_email.Text } );

Hi @WarrenBelz ,
this formula works! But for this -
UpdateIf(
Sessions,
And(sp_id <> Value(txt_sp_id.Text),(cl_code <> txt_cl_code.Text)),
{
cl_code: txt_cl_code.Text,
sp_id: Value(txt_sp_id.Text)
}
);

There's nothing sent to the db...

@Anonymous ,

Apart from some extra brackets, this should work assuming both values do not equal - are you sure you don't need Or() here ?

UpdateIf( Sessions, sp_id <> Value(txt_sp_id.Text) && cl_code <> txt_cl_code.Text, { cl_code: txt_cl_code.Text, sp_id: Value(txt_sp_id.Text) } );
