java - set length is not working in hibernate when table is already created -


employeedesc column on employeedetails table has default length of varchar(255). want altered. have tried giving customised length on persistent class.

@entity public class employeedetails { @id private int employeeid; private string employeename; private int employeeage; @column (length = 500) private string employeedesc;    // getters , setters }

and hibernate configuration.

<property name="hbm2ddl.auto">update</property>

if tried give value more 255 field employeedesc, getting error saying

caused by: com.mysql.jdbc.mysqldatatruncation: data truncation: data long column 'employeedesc' @ row 1

is there better way alter employeedesc's length without changing "hbm2ddl.auto">update property?

hibernate doesn't update column length during updating/validation. can try use liquibase. not sure able use hibernate update liquibase .
