I want use user EF 7 + migration + SQLite. But not all operation is supported.
Can I perform not supported operation manually?
Sample I want remove column.
I add new migration with migrationBuilder.DropColumn (SQLite not support DropColumn)
Can I write code for apply migration with skip DropColumn or run my sql instead of
Solution for SQLite with skip DropColumn
public class DB: DbContext
{
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.ReplaceService<SqliteMigrationsSqlGenerator, SqliteMigrationsSqlGeneratorExt>();
}
}
public class SqliteMigrationsSqlGeneratorExt: SqliteMigrationsSqlGenerator
{
public override IReadOnlyList<MigrationCommand> Generate(IReadOnlyList<MigrationOperation> operations, IModel model = null)
{
//Remover DropColumn from operations
return operations;
}
}
