So implementieren Sie MySQL-Batch-Insert BulkCopy

1. Neues Projekt: SqlSugarDemo

  <ItemGroup>
    <PackageReference Include="SqlSugarCore" Version="5.1.3.52" />
  </ItemGroup>

2. AllowLoadLocalInfile=true wird nicht zur Verbindungszeichenfolge hinzugefügt

Chinesischer Tipp: BulkCopy MySql-Verbindungszeichenfolge muss hinzugefügt werden, wenn es nach dem Hinzufügen immer noch nicht funktioniert, Führen Sie SET GLOBAL local_infile in der MySQL-Datenbank =1 aus.
Englische Nachricht: Verbindungszeichenfolge hinzufügen: AllowLoadLocalInfile=true

show global variables like 'local_infile';
SET GLOBAL local_infile=1
