ObjectDB Database Search

with a string parameter select f from Foo f where substring(f.name, 1, 1) = ?1 but when i use a char , the query does not return anything. i think it should also be possible to use char /Character types ... ) is Character . In ObjectDB as in Java char is comparable to int but not to String. Maybe an exception

I have a class that is persisting a Entity that holds remarks and a time. Then when I query for the latest remark I get a internal error when the remark is larger than 1966 chars . Here is a test class and entity that reproduces the problem on my system. @Entity @Table(name = "TestEntity", schema

sData; } public void setsData(String sData) {   this.sData = sData;   char [] ca = sData
