## Sybase Finder Limitation

If a finder method with an input greater than 255 characters is executed and the primary key column is mapped to a VARCHAR column, Sybase attempts to convert type VARCHAR to type TEXT and generates the following error:

    com.sybase.jdbc2.jdbc.SybSQLException: Implicit conversion from datatype
    'TEXT' to 'VARCHAR' is not allowed.  Use the CONVERT function to run this
    query.

To avoid this error, make sure the finder method input is less than 255 characters.
