Delphi. DBTreeView своими руками. Дополнительный модуль uSQLQueries

Дополнительный модуль, в котором сосредоточены основные SQL запросы. Имена некоторых полей берутся из ObjectInspector.

Из специфичного для MySQL инструкция Insert… Select… для копирования узлов

unit uSQLQueries;

//Здесь будут храниться шаблоны запросов SQL
//Они будут изменяться из ObjectInspector
