These functions allow you to step through each distinct value length for a specific column.

StartLengthFrequency

This function initiates the iterator. It returns 1 to indicate if there are records to iterate through. Otherwise it returns 0.

This function takes two parameters.

Parameters

Name Data Type Description
ColumnName String Column Name to start the iterator.
Order Order This specifies how to order. See Order Enumeration for details.


Syntax int = profiler->StartLengthFrequency(columnNameStr, Order);
C int = mdProfilerStartLengthFrequency(profiler,columnNameStr, Order);
.Net integer = profiler.StartLengthFrequency(columnNameStr, Order);


GetLengthFrequencyValue

This function returns a column's distinct length.

This function takes one parameter.

Parameters

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


Syntax profiler->GetLengthFrequencyValue(ColumnNameStr);
C integer = mdProfilerGetDataFrequencyValue(profiler,columnNameStr);
.Net integer = profiler.GetDataFrequencyValue(columnNameStr);


GetLengthFrequencyCount

This function returns the number of times the length appears in the profiled data for this particular column.

This function takes one parameter.

Parameters

Name Data Type Description
ColumnName String Column Name to get the number of times the length appears in the profiled data.


Syntax profiler->GetLengthFrequencyCount(columnNameStr);
C integer = mdProfilerGetLengthFrequencyCount(profiler,columnNameStr);
.Net integer = profiler.GetLengthFrequencyCount(columnNameStr);


GetNextLengthFrequency

This function steps to the next distinct length. It returns 1 if there are more distinct lengths or 0 when there are no more lengths.

This function takes one parameter.

Parameters

Name Data Type Description
ColumnName String Column Name to get the next distinct length.


Syntax profiler->GetNextLengthFrequency(ColumnNameStr);
C integer = mdProfilerGetNextLengthFrequency(profiler,columnNameStr);
.Net integer = profiler.GetNextLengthFrequency(columnNameStr);
