Tips and Tricks

  • Use contains to cut the amount of typing required; e.g. write variety.dialect contains "Ligurian - Genovese" rather than variety.dialect = "Italian - Northern I - Ligurian - Genovese".
  • Use the symbol * for 'any character' (e.g. verb_form.text ends with "t*" would return any verb_form that ends with followed by exactly one character)."

Formal Specification

A query is a statement of the form view <object_type> where <expression> sorting by <sort_statement> where the sort statement is optional and:

  • <object_type> is one of varieties, verbs and verb_forms and specifies the type of object that you wish to retrieve.
  • <sort_statement> consists of a comma-separated list of <property> elements that specify the sort order of the results. verb_form.variety, verb_form.subject
  • <property> is one of:
    • verb_form
    • verb_form.text
    • verb_form.subject
    • verb_form.variety
    • verb_form.verb
    • verb_form.grammatical_category
    • grammatical_category.no_form
    • grammatical_category.name
    • grammatical_category.verb
    • grammatical_category.variety
    • verb
    • verb.etymon
    • verb_form.variety
    • variety
    • variety.dialect
    or a property such as verb_form.variety.dialect. Note that the first part of the property (i.e. the bit before the first .) must match the current object_type <object_type>. For example, the query view verb_forms where variety.name = "..." is invalid and should instead be specified by view verb_forms where verb_form.variety.name = "...".
  • <expression> is one of the following:
    • (<expression>) which is true if the expression is;
    • <expression> and <expression> which is true if both expressions are true;
    • <expression> or <expression> which is true if one of expressions is true;
    • not <expression> which is true if the expression is false;
    • <property> = "<value>" which is true if the property is exactly equal to the value;
    • <property> != "<value>" which is equivalent to not (<property> = "<value>");
    • <property> contains "<value>" which is true if the property contains the value somewhere in it;
    • <property> begins with "<value>" which is true if the property starts with the value;
    • <property> ends with "<value>" which is true if the property ends with the value;
    • <property> in [<values>] where <values> is a comma separated list of "<value>" elements and is true if the property is exactly equal to a value in the list;
    • <property> is True which is true if the property is True;
    • <property> is False which is true if the property is False;
    • <object> has <child_object> where (<expression>) where <object> and <child_object> are each one of verb_form, verb, grammatical_category and variety. It is true if <object> contains a <child_object> such that <expression> is true.
