The issue comes because \x is interpreted as an escape character. One way to avoid this is change the \ by / in all path. If You don't want to do that you can use \\ what means \ itself for each \ in the text You are looking for. For instance:
If You stored 'D:\Test' in the column db_catalogo_tb_import.path the the select command should be like:
select * from db_catalogo.tb_import where db_catalogo.tb_import.path='D:\\Test';
If You stored 'D:\\Test' then the select command should be like:
select * from db_catalogo.tb_import where db_catalogo.tb_import.path='D:\\\\Test';
