-----------------------------------------
Summary: Basic type-conversion (scalar) functions TO_NUMBER,
TO_STRING, TO_DATE and TO_BOOLEAN
Key: METAMODEL-192
URL: https://issues.apache.org/jira/browse/METAMODEL-192
Project: Apache MetaModel
Issue Type: Improvement
Reporter: Kasper Sørensen
Assignee: Kasper Sørensen
With the addition of scalar functions, we should have a basic set of built-in
functions.
This issue represents the need to have basic type-conversion functions for
converting values into a new data type. I propose to add 4 built-in functions
for that:
TO_STRING
TO_NUMBER
TO_DATE
TO_BOOLEAN
When possible this conversion should obviously be done by the backing database.
But initially we should also cover all data context implementations by having a
client-side application of it.
