Description
I have a simple document structure in Couchbase (no nested documents, all values are strings, integers, and booleans).
I have a source model with proper types (strings, integers, booleans) and view model defined with my target types (float, double, date,...) all with appropriate conversion.
There are basically two issues:
- When I try to retrieve all data from the view, Teiid ends with exception [1]. This is wired.
- When I try to use explicit convert on some columns from source table (not view) it ends with similar exception [2].
Additional information:
I represent 'Null' values by excluding key from the document (nevertheless, same error occurs even if I add explicit "key":null to the definition of the document).
[1]
TEIID10076 Invalid conversion from type class java.lang.Integer with value '-24' to type class java.sql.Date
[2] - case for data value
TEIID10076 Invalid conversion from type class java.lang.Object with value '{}' to type class java.sql.Date
