Fields

Error_Concurrency_UpdateWithRefresh_NotSupported 

public const string Error_Concurrency_UpdateWithRefresh_NotSupported = "UpdateOptimisticWithRefresh requires the provider to either return updated rows from the UPDATE statement (OUTPUT / RETURNING) or report the number of affected rows. The current provider supports neither, so the optimistic-concurrency result cannot be guaranteed."

Field Value

string

Error_Concurrency_UpdateWithRefresh_ReadOnlyLockMember 

public const string Error_Concurrency_UpdateWithRefresh_ReadOnlyLockMember = "UpdateOptimisticWithRefresh cannot refresh '{0}.{1}': the optimistic-lock member has no setter, so the regenerated value cannot be written back onto the entity."

Field Value

string

Error_Concurrency_UpdateWithRefresh_UnsupportedSource 

public const string Error_Concurrency_UpdateWithRefresh_UnsupportedSource = "UpdateOptimisticWithRefresh cannot refresh through '{0}': the query operator does not expose the updated table as its source, so the regenerated value cannot be read back reliably."

Field Value

string

Error_Correlated_Subqueries 

public const string Error_Correlated_Subqueries = "Provider does not support correlated subqueries."

Field Value

string

Error_Correlated_Subqueries_Level 

public const string Error_Correlated_Subqueries_Level = "Provider does not support correlated subqueries in more than {0} level."

Field Value

string

Error_DistinctByRequiresOrderBy 

public const string Error_DistinctByRequiresOrderBy = "DistinctBy requires at least one ordering key."

Field Value

string

Error_EnumerationNotStarted 

public const string Error_EnumerationNotStarted = "Enumeration not started."

Field Value

string

Error_GroupGuard 

public const string Error_GroupGuard = "You should explicitly specify selected fields for server-side GroupBy() call or add AsEnumerable() call before GroupBy() to perform client-side grouping.\r\nSet Configuration.Linq.GuardGrouping = false to disable this check.\r\nAdditionally this guard exception can be disabled by extension GroupBy(...).DisableGuard().\r\nNOTE! By disabling this guard you accept Eager Loading for grouping query."

Field Value

string

Error_ImplicitEagerLoadingNotAllowed 

public const string Error_ImplicitEagerLoadingNotAllowed = "Implicit eager loading is not allowed (LinqOptions.ImplicitCollectionLoading = Throw): a collection was projected without an explicit eager-load request. To allow it, request the load explicitly with LoadWith()/ThenLoad(), or opt the whole query in with WithUnionLoadStrategy()/WithKeyedLoadStrategy()/WithSeparateLoadStrategy() — or set ImplicitCollectionLoading = Allow to turn the guard off."

Field Value

string

Error_Internal_UpdateInsertEmitter_CannotEmitUpdatePredicate 

public const string Error_Internal_UpdateInsertEmitter_CannotEmitUpdatePredicate = "Internal error: BuildInsertOrUpdateQueryAsUpdateInsert cannot emit an UPDATE predicate. Providers with IsInsertOrUpdateWithPredicateSupported=false must route Upsert.Update.When through SetIfExistsUpdateElseInsert (3-query orchestration)."

Field Value

string

Error_Interval_ComponentBelowResolution

{0} - the requested component unit, {1} - the finest unit the provider resolves.

public const string Error_Interval_ComponentBelowResolution = "Current provider measures elapsed time to the {1}, so the {0} component of an interval is always zero and is not translated."

Field Value

string

Error_Interval_Difference

Spelled out rather than terse, unlike its neighbours, because this one describes a capability that was taken away rather than one that never existed: before 6.5 the same expression was rewritten into Sql.DateDiff, which counts crossed boundaries instead of measuring elapsed time. Provider-neutral wording because more than one provider reaches it.

public const string Error_Interval_Difference = "Subtracting one date/time value from another is not supported by current provider. Compute the difference in .NET, or use Sql.DateDiff where a count of crossed unit boundaries answers the question."

Field Value

string

Error_Interval_Member 

public const string Error_Interval_Member = "This TimeSpan member is not supported by current provider."

Field Value

string

Error_Interval_Operation 

public const string Error_Interval_Operation = "This TimeSpan operation is not supported by current provider."

Field Value

string

Error_Interval_Shift 

public const string Error_Interval_Shift = "Adding a TimeSpan to a date/time value is not supported by current provider."

Field Value

string

Error_Interval_UndeclaredOperand

Names the declaration rather than the provider, because no provider can answer this one: the two stored numbers are counted in different units and only one of them says so.

public const string Error_Interval_UndeclaredOperand = "Cannot combine a duration whose unit is declared with one stored through a value converter, which does not say what its number counts. Declare that column with DurationAttribute, or combine the two in .NET."

Field Value

string

Error_JoinOnOuterReferenceNotSupported

Error_Upsert_EmulationDisallowed 

public const string Error_Upsert_EmulationDisallowed = "Upsert cannot be expressed natively for this provider / configuration and would fall back to an emulated UPDATE+INSERT sequence.

Field Value

string

Error_Upsert_InsertBranch_DoNothing_With_Ops 

public const string Error_Upsert_InsertBranch_DoNothing_With_Ops = "Insert branch configuration is contradictory: DoNothing() cannot be combined with Set/Ignore/When."

Field Value

string

Error_Upsert_MergeLowering_NotSupported 

public const string Error_Upsert_MergeLowering_NotSupported = "Upsert configuration requires MERGE lowering (bulk source, non-PK match, conditional Insert, or SkipInsert), but the current provider does not support the two-branch MERGE shape. Reshape the Upsert call to a single-entity PK match without SkipInsert / Insert.When, or target a MERGE-capable provider."

Field Value

string

Error_Upsert_MergeWithPredicate_NotSupported 

public const string Error_Upsert_MergeWithPredicate_NotSupported = "Upsert configuration attaches a predicate to an Insert.When / Update.When branch routed through MERGE lowering, but the current provider's MERGE dialect has no WHEN [NOT] MATCHED AND <cond> or UPDATE … WHERE <cond> form. Remove the .When predicate, or target a provider that supports conditional MERGE branches."
