Properties

ExistsSql

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

protected override string ExistsSql { get; }

Property Value

string

LockReleaseBehavior

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

public override LockReleaseBehavior LockReleaseBehavior { get; }

Property Value

LockReleaseBehavior

Methods

AcquireDatabaseLock()

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

public override IMigrationsDatabaseLock AcquireDatabaseLock()

Returns

IMigrationsDatabaseLock

AcquireDatabaseLockAsync(CancellationToken)

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

public override Task<IMigrationsDatabaseLock> AcquireDatabaseLockAsync(CancellationToken cancellationToken = default)

Parameters

cancellationToken CancellationToken

Returns

Task<IMigrationsDatabaseLock>

Exists()

Always returns true for PostgreSQL - it's difficult to reliably check if the migration history table exists or not (because user may set PG search_path, which determines unqualified tables references when creating, selecting). So we instead catch the "table doesn't exist" exceptions instead.

public override bool Exists()

Returns

bool

ExistsAsync(CancellationToken)

Always returns true for PostgreSQL - it's difficult to reliably check if the migration history table exists or not (because user may set PG search_path, which determines unqualified tables references when creating, selecting). So we instead catch the "table doesn't exist" exceptions instead.

public override Task<bool> ExistsAsync(CancellationToken cancellationToken = default)

Parameters

cancellationToken CancellationToken

Returns

Task<bool>

GetAppliedMigrations()

Calls the base implementation, but catches "table not found" exceptions; we do this rather than try to detect whether the migration table already exists (see ExistsAsync(CancellationToken) override below), since it's difficult to reliably check if the migration history table exists or not (because user may set PG search_path, which determines unqualified tables references when creating, selecting).

public override IReadOnlyList<HistoryRow> GetAppliedMigrations()

Returns

IReadOnlyList<HistoryRow>

GetAppliedMigrationsAsync(CancellationToken)

Calls the base implementation, but catches "table not found" exceptions; we do this rather than try to detect whether the migration table already exists (see ExistsAsync(CancellationToken) override below), since it's difficult to reliably check if the migration history table exists or not (because user may set PG search_path, which determines unqualified tables references when creating, selecting).

public override Task<IReadOnlyList<HistoryRow>> GetAppliedMigrationsAsync(CancellationToken cancellationToken = default)

Parameters

cancellationToken CancellationToken

Returns

Task<IReadOnlyList<HistoryRow>>

Parameters
