PipelineBuffer::IsNull Method (Int32)
Checks to see if the data in a buffer column is null.
Assembly: Microsoft.SqlServer.PipelineHost (in Microsoft.SqlServer.PipelineHost.dll)
Parameters
- columnIndex
-
Type:
System::Int32
The index of the column in the buffer row.
It is recommended that you call the IsNull method prior to calling a data type accessor method, such as GetBoolean, because the PipelineBuffer will produce a ColumnIsNullException if the column is null.
