      Description

      An attempt to create a table that contains a column of type CHAR with a size greater than 254 using the SQL statement

      CREATE TABLE dummyTable ( column1 char(255),column2 char(10),column3 char(10) )

      results in the following SQL Exception:

      SQL Exception: The length, precision, or scale attribute for column, or type mapping 'CHAR(255)' is not valid.
      SQL Error: 30000
      SQL State: 42611

      However, if you decrease column1's length by one as below, the table is created successfully:

      CREATE TABLE dummyTable ( column1 char(254),column2 char(10),column3 char(10) )

      The Derby Reference Manual states that the limit on the length of a CHAR data type is java.lang.Integer.MAX_VALUE:
