In my case i have a enum type in postgres:
create type my_type as enum (string value);
And some tables, using this as column type:
create table A (
...
t my_type,
...
)
In postgres i can insert new record in table A like this:
insert into A values(..., 'my_type_value', ...);
Scalikejdbc generates correct sql:
insert into A (...) values (..., 'my_type_value', ...)
But fails with an error:
ERROR: column "t" is of type my_type but expression is of type character varying HINT: You will need to rewrite or cast the expression.
I tried to do this:
object MyType extends Enumeration {...}
case class A(..., t: MyType, ...)
object A extends SQLSyntaxSupport[A] {
def apply(rs: WrappedResultSet): A = A(..., rs.getString('t'), ...)
}
Also, i tried to add implicit convertions in enum type in scala code:
object MyType extends Enumeration {
implicit def stringToValue...
implicit def valueToString ...
}
But it didn't help too.
Insert code looks like this:
withSQL {
insertInto(A).namedValues(
...
A.column.t-> e.t, // e - passed entity into insert fun
....
)
}.update().apply()
Finally, solved it. I have to add implicit converter:
implicit val valueToParameterBinder: ParameterBinderFactory[MyType] = ParameterBinderFactory {
value => (stmt, indx) => stmt.setObject(indx, value, Types.OTHER)
}
object A extends SQLSyntaxSupport[A] {
def apply(rs: WrappedResultSet): A = A(..., rs.getString('t'), ...) // just call getString as usual
}
