How can i do, that if my field in db is less then 10

  • 0

How can i do, that if my field in db is less then 10 symbols, search via non strong like, but if more than 10, than with %% options?
So how to check field length?

My code in ruby is such:

@search = CrossList.find(:all, :conditions => ['cross_value like ? ', oem_condition])

But how to do something like:

@search = CrossList.find(:all, :conditions => ['length(cross_value) < 10 and cross_value like ? ', oem_condition])

else

 @search = CrossList.find(:all, :conditions => ['length(cross_value) >= 10 and cross_value like %?% ', oem_condition])

    Use two conditions, and OR them together:

    @search = CrossList.find(:all, :conditions => [
   "(length(cross_value) >= 10 AND cross_value like CONCAT('%',?,'%')) OR (length(cross_value) < 10 AND cross_value like ?) ",
    oem_condition,
    oem_condition
])

    The LENGTH() condition must be met by one of the two () groups, and whichever is met will also require that the LIKE condition with which it is AND‘d will be applied.
