Type annotations in SQL template placeholders
agentgt opened this issue · comments
To keep accidentally data coercion with JDBC happening with SQL templates type annotations might be useful using the format -- {name:type}
and --{:type}
.
Example:
SELECT * FROM STUFF
WHERE ID = 1 -- {id:long}
Obviously this is not compile time type safety but run time type checking. That is for example if you bind a int
, Integer
, or String
or anything else that is not a long
or Long
an error will happen when the place holders parameters are merged (.mergedParameters()
). The type annotations will need to be consistent. That is you cannot later set -- {id:String}
with in the same SQL template.
