示例1: Add
protected override IEnumerable<MigrationOperation> Add(IKey target)
{
var operation = base.Add(target)
.Single(o => o is AddPrimaryKeyOperation || o is AddUniqueConstraintOperation);
if (target.Npgsql().IsClustered != null)
{
operation[NpgsqlAnnotationNames.Prefix + NpgsqlAnnotationNames.Clustered] =
target.Npgsql().IsClustered.ToString();
}
yield return operation;
}示例2: Diff
protected override IEnumerable<MigrationOperation> Diff(IKey source, IKey target)
{
var operations = base.Diff(source, target).ToList();
var addOperation = operations.SingleOrDefault(o => o is AddPrimaryKeyOperation || o is AddUniqueConstraintOperation);
if (addOperation == null)
{
if (source.Npgsql().IsClustered != target.Npgsql().IsClustered)
{
if (source != null
&& !operations.Any(o => o is DropPrimaryKeyOperation || o is DropUniqueConstraintOperation))
{
operations.AddRange(Remove(source));
}
operations.AddRange(Add(target));
}
}
else if (target.Npgsql().IsClustered != null)
{
addOperation[NpgsqlAnnotationNames.Prefix + NpgsqlAnnotationNames.Clustered] =
