The column-based statistics should only be retrieved after ProfileData is called. These functions return column-specific details.
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%.
SetRightFielderAnalysis must be set to true to get inferred datatype analysis.
This function takes one parameter.
Parameters
Name | Data Type | Description |
---|---|---|
ColumnName | String | Column Name to get the column’s inferred data type. |
Syntax | profiler->GetColumnInferredDataType(columnNameStr); |
---|---|
C | ProfilerDataType = mdProfilerGetColumnInferredDataType(profiler, columnNameStr); |
.Net | ProfilerDataType = profiler.GetColumnInferredDataType(columnNameStr); |
GetColumnInferredColumnType
Along with the data type analysis, the Profiler will also analyses the column type and return.
ProfilerColumnType enumerator that is the closest to what the column type is. This could be different than the column type specified by the user. Possible values that this function could return are: ColumnTypeInt1, ColumnTypeReal8, ColumnTypeBoolean, ColumnTypeDate, etc.
SetRightFielderAnalysis must be set to true to get inferred datatype analysis.
This function takes one parameter.
Parameters
Name | Data Type | Description |
---|---|---|
FieldName | String | A string value representing the Field Name. |
Syntax | ProfilerColumnType = profiler->GetColumnInferredColumnType(FieldName); |
---|---|
C | ProfilerColumnType = mdProfilerGetColumnInferredColumnType(profiler, FieldName); |
.Net | ProfilerColumnType = profiler.GetColumnInferredColumnType(FieldName); |
GetColumnSortation
This function returns a column's natural sortation. This is the sortation order seen in the values as they were input. In order for a column to be considered near-sorted, no more than 10% of the input values must be out of order.
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 |
---|---|---|
0 | SortUnknown | No sortation detected. |
1 | SortStringAscending | Values are sorted ascending, using a string comparison. |
2 | SortStringDescending | Values are sorted descending, using a string comparison. |
3 | SortNumericAscending | Values are sorted ascending, using a numeric comparison. |
4 | SortNumericDescending | Values are sorted descending, using a numeric comparison. |
5 | SortDateAscending | Values are sorted ascending, using date/time comparison. |
6 | SortDateDescending | Values are sorted descending, using date/time comparison. |
Syntax | profiler->GetColumnSortation(columnNameStr); |
---|---|
C | Sortation = mdProfilerGetColumnSortation(profiler, columnNameStr); |
.Net | Sortation = profiler.GetColumnSortation(columnNameStr); |
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.
Parameters
Name | Data Type | Description |
---|---|---|
ColumnName | String | Column Name to get the sortation percentage |
Syntax | profiler->GetColumnSortationPercent(columnNameStr); |
---|---|
C | double = mdProfilerGetColumnSortationPercent(profiler, columnNameStr); |
.Net | double = profiler.GetColumnSortationPercent(columnNameStr); |
GetColumnMostPopularCount
This function returns the number of records that contain the most popular value.
This function takes one parameter
Parameters

---|---|
C | integer = mdProfilerGetColumnMostPopularCount(profiler, columnNameStr); |
.Net | integer = profiler.GetColumnSortationMostPopulatCount(columnNameStr); |
GetColumnDistinctCount
This returns the number of distinct values in a column. Distinct values may have duplicates. A group of duplicate values is counted as 1 distinct value.
For example, the table below has a distinct count of 11 and a unique count of 7. Each state is a distinct value, even if it has duplicates in the data frequency.

ColumnName | String | Column Name to get total spaces. |
Syntax | profiler->GetColumnTotalSpaces(columnNameStr); |
---|---|
C | integer = mdProfilerGetColumnTotalSpaces(profiler, columnNameStr); |
.Net | integer = profiler.GetColumnTotalSpaces(columnNameStr); |
GetColumnTotalWordBreaks
This function returns the total number of word breaks found in the column values.
This function takes one parameter.
Parameters
Name | Data Type | Description |
---|---|---|
ColumnName | String | Column Name to get total word breaks. |
Syntax | profiler->GetColumnTotalWordBreaks(ColumnNameStr); |
---|---|
C | integer = mdProfilerGetColumnTotalWordBreaks(profiler, columnNameStr); |
.Net | integer = profiler.GetColumnTotalWordBreaks(columnNameStr); |
GetColumnAvgSpaces
This function returns the average number of spaces found between words in the column values.
This function takes one parameter.
Parameters
Name | Data Type | Description |
---|---|---|
ColumnName | String | Column Name to get average spaces. |
Syntax | profiler->GetColumnAvgSpaces(ColumnNameStr); |
---|---|
C | double = mdProfilerGetColumnAvgSpaces(profiler, columnNameStr); |
.Net | double = profiler.GetColumnAvgSpaces(columnNameStr); |
GetColumnDecorationCharCount
This function returns the number of records with the values containing decorative characters. Decorative characters appear at the beginning or end of the value, and are tab, comma, pipe, and double-quote. This count is useful because it often indicates that field delimiters may have somehow found their way into the data stream.
Decorative character analysis is meant to detect bad data imports by flagging (returning result code QS07) and counting any delimiters that made their way to the values of your table.
This function takes one parameter.
Parameters
Name | Data Type | Description |
---|---|---|
ColumnName | String | Column Name to decorative character count. |
Syntax | profiler->GetColumnDecorationCharCount(columnNameStr); |
---|---|
C | integer = mdProfilerGetColumnDecorationCharCount(profiler, columnNameStr); |
.Net | integer = profiler.GetColumnDecorationCharCount(columnNameStr); |
GetColumnProfanityCount
This function returns the number of records with values containing profanity.
This function takes one parameter.
Parameters
Name | Data Type | Description |
---|---|---|
ColumnName | String | Column Name to get profanity count. |
Syntax | profiler->GetColumnProfanityCount(columnNameStr); |
---|---|
C | integer = mdProfilerGetColumnProfanityCount(profiler, columnNameStr); |
.Net | integer = profiler.GetColumnProfanityCount(columnNameStr); |
GetColumnInconsistentDataCount
This function returns the number of records with values that are inconsistent with the Data Type you set with the AddColumn function. Record inconsistency is evaluated by analyzing a record's column values and determining what type of data each value represents. This determination is not an absolute, as a value can often be mistaken for another type.
This function takes one parameter.
Parameters
Name | Data Type | Description |
---|---|---|
ColumnName | String | Column Name to get Inconsistent data count. |
Syntax | profiler->GetColumnInconsistentDataCount(columnNameStr); |
---|---|
C | integer = mdProfilerGetColumnInconsistentDataCount(profiler, columnNameStr); |
.Net | integer = profiler.GetColumnInconsistentDataCount(columnNameStr); |
