GRAILS使用to_char命名查询

Question

I am looking to query the matching records based on input number(say 56). The type of the column in ORACLE DB is Long. Expecting all matching records has the numbers for ex - 156, 567, 12356..etc. Is it possible to write a named query in GRAILS for above ?. Is there any other way out ?

Answer 1

If you want to use database functions in your named queries, you can use the sqlRestriction clause. Note that the syntax must match you table and not domain class, so considering:

class MyDomain {
  Date myField
}

Your restriction can be:

def namedQueries = {
  someQuery {
    sqlRestriction("to_char(my_field, 'dd/mm/yyyy') = '25/07/2013'")
  }
}
