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 

public const string Error_JoinOnOuterReferenceNotSupported = "Provider does not support JOIN conditions that reference outer queries."

public const string Error_Take_in_Subquery = "Provider does not support Take value in subquery."

Field Value

string

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. LinqOptions.UpsertEmulationPolicy is set to Throw — change the provider, adjust the Upsert configuration, or set it to Allow to permit emulation."

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."

Field Value

Field Value

string

Error_Upsert_UpdateBranch_DoNothing_With_Ops 

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

Field Value

string

Error_ValueConverter_DivergentOperands

{0} and {1} - the two columns. Named rather than described, because two conversions are indistinguishable in the query text and the mistake is in the model rather than in what was written.

public const string Error_ValueConverter_DivergentOperands = "Cannot combine '{0}' and '{1}' in the database: their value converters do not agree on what a stored value counts, so the two stored values are not commensurable and the result would be read through one of the conversions only. Combine them in .NET, or give both columns the same conversion."
