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); |
