add_field_value_id

Valid only for: INSERT, UPDATE, SELECT statements

• For UPDATE: specifies that the field represented by field_id will be set to the value identified by value_id.
• For SELECT: add a selected item to the statement, and if value_id is not typeof ( unichar2)0, then use it as an alias
• For INSERT: if field_id represents an SQL identifier (obtained using add_id): then if value_id is not typeof (unichar2)0 then specifies that the field represented by field_id will be set to the value identified by value_id, otherwise just specifies a named field to be given a value. If field_id represents a sub SELECT (obtained using gda_sql_builder_add_sub_select), then this method call defines the sub SELECT from which values to insert are taken.
