Class DecimalPrecisionAttribute

Namespace
NextORM.Core
Assembly
nextorm.core.dll

Declares the decimal precision and scale of a mapped decimal property. The pair is read by IPropertyMetadata (DecimalPrecision and DecimalScale) and used where a provider needs the declared precision/scale, such as the column metadata of a table-valued parameter.

The declared domain is provider-neutral and bounded by SQL Server's maximum: precision must be between 1 and 38, and scale between 0 and the precision. A provider without a native decimal precision (for example ClickHouse's Decimal(P, S)) honours the same pair; a provider that does not need it keeps its default. The pair is validated against the type actually bound for the column: a non-decimal model mapped through a value converter to decimal is accepted, while a decimal model mapped to a non-decimal representation (a converter to string or a JSON column) is rejected. An out-of-range pair throws ArgumentOutOfRangeException; a pair declared on a non-decimal bound type or a partially declared pair throws InvalidOperationException.

Remarks

The equivalent fluent mapping is DecimalPrecision(int, int). The attribute affects only the declared column metadata; nextorm does not generate DDL, so the column must already have a matching precision/scale (the equivalent of HasColumnType("decimal(12,4)") in EF Core).
