Bonjour à tous.
Je suis confronté à un problème urgent
Une procédure stockée (non paramétrée) sur SQL-Server met à jour une table à partie d'une autre table.
Si je lance la procédure à partir de l'analyseur de requêtes SQL, elle s'exécute en une seconde.
La même procédure appelée à partir de Delphi (Delphi 5, ADOConnection et ADOCommand) met 7 minutes au bas mot.
Quelle est la bonne configuration ADO, où ais-je faux ?
Merci d'avance.
Lors de l'exécution via Delphi, quels sont l'état des processus (sp_who) et des verrous (sp_lock) ?
Voici les 2 états pendant l'exécution:
le processus Delphi appellant la procédure stockée est le 106

il serait plus facile de verifier tes procedures de verrouillage.
Utilises tu le verrouillage pessimiste ou bien optimiste ?
