## Remarks
The <xref:System.Data.SqlClient.SqlParameter.Scale%2A> property is used by parameters that have a <xref:System.Data.SqlDbType> of `Decimal`.
The <xref:System.Data.SqlClient.SqlParameter.Scale%2A> property is used by parameters that have a <xref:System.Data.SqlDbType> of `Decimal`, `DateTime2`, `DateTimeOffset` or `Time`.

> [!WARNING]
> Data may be truncated if the <xref:System.Data.SqlClient.SqlParameter.Scale%2A> property is not explicitly specified and the data on the server does not fit in scale 0 (the default).

> For the `DateTime2` type, scale 0 (the default) will be passed as datetime2(7). There is currently no way to send a parameter as datetime2(0). Scales 1-7 work as expected.
This problem applies to `DateTimeOffset` and `Time` as well.

You do not need to specify values for the <xref:System.Data.SqlClient.SqlParameter.Precision%2A> and <xref:System.Data.SqlClient.SqlParameter.Scale%2A> properties for input parameters, as they can be inferred from the parameter value. `Precision` and `Scale` are required for output parameters and for scenarios where you need to specify complete metadata for a parameter without indicating a value, such as specifying a null value with a specific precision and scale.
