I have modeled a physical procedure with a nativeQuery property

when I set the property to this SELECT * FROM INFORMATION_SCHEMA.TABLES where table_cat='\\x\Datae\Client\6274\028\Tables'

the query runs fine

I then cloned this and changed the nativequery to this:

SELECT * FROM INFORMATION_SCHEMA.TABLES where table_Cat = $TableCat

TableCat is the name of the input property (I've tried naming it 1 just to match the documentation!)

However, when I run a query at runtime:

select * from INfoSchemaObjs where tableCat ='\\x\Datae\Client\6274\028\Tables'

it returns no results

From the logs it looks as though the '\\x\Datae\Client\6274\028\Tables' isn't being substituted for $TableCat

What am I missing?
