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

StartPatternFrequency

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->StartPatternFrequency(columnNameStr, Order);
C int = mdProfilerStartPatternFrequency(profiler,columnNameStr, Order);
.Net integer = profiler.StartPatternFrequency(columnNameStr, Order);


GetPatternFrequencyValue

This function returns a column's distinct pattern.

This function takes one parameter.

Parameters

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


Syntax profiler->GetPatternFrequencyValue(columnNameStr);
C const char* = mdProfilerGetPatternFrequencyValue(profiler,columnNameStr);
.Net string = profiler.GetPatternFrequencyValue(columnNameStr);


GetPatternFrequencyRegEx

This function returns a regular expression for a distinct pattern. The regular expressions are 'tuned' for your specified data type. Where appropriate, letters or numbers may be lumped together using the 'one or more' quantifier.

This function takes one parameter.

Parameters

Name Data Type Description
ColumnName String Column Name to get a regular expression for a distinct pattern.


Syntax profiler->GetPatternFrequencyRegEx(columnNameStr);
C const char* = mdProfilerGetPatternFrequencyRegEx(profiler,columnNameStr);
.Net string = profiler.GetPatternFrequencyRegEx(columnNameStr);


GetPatternFrequencyExample

This function returns an example value represented by the pattern. This will always be the first value encountered while profiling.

This function takes one parameter.

Parameters

Name Data Type Description
ColumnName String Column Name to get an example value represented by the pattern.


Syntax profiler->GetPatternFrequencyExample(columnNameStr);
C const char* = mdProfilerGetPatternFrequencyExample(profiler,columnNameStr);
.Net string = profiler.GetPatternFrequencyExample(columnNameStr);


GetPatternFrequencyCount

This function returns the number of times the pattern 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 pattern appears in the profiled data.


Syntax profiler->GetPatternFrequencyCount(columnNameStr);
C integer = mdProfilerGetPatternFrequencyCount(profiler,columnNameStr);
.Net integer = profiler.GetPatternFrequencyCount(columnNameStr);


GetNextPatternFrequency

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

This function takes one parameter.

Parameters

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


Syntax profiler->GetNextPatternFrequency(columnNameStr);
C integer = mdProfilerGetNextPatternFrequency(profiler,columnNameStr);
.Net integer = profiler.GetNextPatternFrequency(columnNameStr);
