|
| la __order by CLI,ART__ non dovrebbe essere (almeno a livello generale) significativa giusto? |
|
| !! Meglio nella WHERE O nella JOIN? |
|
| Da quello che ho capito l'istruzione di WHERE è riferita ad una tabella joinata. |
| Se viene effettuata una "inner join" dovrebbero essere equivalenti |
| Se viene effettuata una "left join" verrebbero invece esclusi tutti i record non presenti nella tabella joinata, riconducendola quindi ad una "inner join". |
| Non sarebbe meglio utilizzare come "best practice" la selezione a livello di clausola JOIN? |
| Cosa ne pensate? |
