Sql importat instrumentum ad Excel

Vestigia huius VBA tortor sunt hae:

1. SQL lima per tabellam alternis eligere.
2. Lege tabella contenta.
3. Parse cuiusque lineae in tabella et nomen mensae extrahe si contineat "inserere".
4. Impedit an officina tabulae nomine iam existat, et novum officinam creat si non existit.
5. Data in inserere in officina respondentem.

Indicium: Quia quaestiones ut casus SQL textus in actu magis implicantur, hoc exemplo caute utere.
Quaedam inexspectata condiciones, ut aliquae regiones continentes) values Et sic de aliis, principaliter est quaestio positionis, et deinde longitudo valoris, si est aliquid in valore.,Commatis, deinde spatiis et aliis constitutionibus;
Pythone utatur facilius;
sequentiVBAScriptum est ad referendum;

Ad hunc modum:

insert into aaa (aa,bb,cc) values ('2','','3aa');
insert into aaa (aa,bb,cc) values ('1',null,'');
