Profiler Object:Column-Based Statistics

← Profiler Object Reference

The column-based statistics should only be retrieved after ProfileData is called. These functions return column-specific details.

GetColumnColumnType

This function returns a column’s Columns Type in ProfilerColumType form. See ProfilerColumnType Enumerations for details. You specify the Column Type by using the AddColumn function.

This function takes one parameter.

Parameters

Name	Data Type	Description
ColumnName	String	Column Name to get the column type

Syntax	profiler->GetColumnColumnType(columnNameStr);
C	ProfilercolumnType = mdProfilerProfilerGetColumnColumnType(profiler,columnNameStr);
.Net	ProfilerColumnType = profiler.GetColumnColumnType(columnNameStr);

Parameters

Name	Data Type	Description
ColumnName	String	Column Name to get the column’s Data Type.

Syntax	profiler->GetColumnDataType(columnNameStr);
C	ProfilerDataType = mdProfilerGetColumnDataType(profiler, columnNameStr);
.Net	ProfilerDataType = profiler.GetColumnDataType(columnNameStr);

GetColumnSize

GetColumnInferredDataType

This function returns a column’s inferred data type in ProfilerDataType form. See ProfilerDataType Enumerations for details. The inferred data type is used to determine if a prevalent data type is seen for the majority of values in this column. For a deviant value to be returned (i.e., a value that differs from the user-specified data type), the count of that detected data type must exceed all other detected data type counts by at least 20%.

This function accepts one parameter.

Parameters

Name	Data Type	Description
ColumnName	String	Column Name to get the column’s sortation information.

Return Value

This function returns one of the following enumerations.

Enum Value	Sortation Type	Description

GetColumnSortationPercent

This function returns a percentage indicating how well a column is sorted. This is only reported for columns where GetColumnSortation returned a value other than SortUnknown. The sortation percentage is determined by counting the number of re-ordering values that would be required to put the list of values into a sorted state, and then dividing this value by the worst-case value (i.e., re-ordering required for a reverse-sorted list.)

This function takes one parameter.
