Not all JDBC drivers support
java.lang.Character
(for whatever reason). Notably MariaDB, Oracle and SQL Server. I've added aFieldConverter
to convert the SQL arg into a String which is accepted by all 3 (+ 1 for JTDS) JDBC drivers. Note that the underlying SQL type remains unchanged so this should have no backwards compatibility concerns.The new
CharacterCompatFieldConverter
currently resides in this repository but it should probably be moved into ormlite-core. Perhaps into a new packagecom.j256.ormlite.field.converters
where we can also moveBooleanNumberFieldConverter
too (currently resides inBaseDatabaseType
).This fixes some exceptions first reported in issue #2.
