You must call AddColumn for each column you intend to profile. All columns must be added before StartProfiling is called.

AddColumn

This function describes a column to be profiled. To successfully profile the data, at least one column should be added. This function accepts three parameters.

Parameters

Name Data Type Description
ColumnName String This is the name of the column to be added.
ColumnType Profiler Column Type This is the type of the column to be added. See ProfilerColumnType Enumerations for details.
DataType Profiler Data Type This is the data type of the column to be added. These are custom data types. See ProfilerDataType Enumerations for details.


Syntax profiler->AddColumn(columnNameStr, profilerColumnTYpe, profilerDataType);
C mdProfilerAddColumn(profiler,columnNameStr,profilerColumntype,profilerDataType);
.Net profiler.AddColumn(columnNameStr, profilerColumntype, profilerDataType);


SetColumnCustomPattern

Optional. This function adds a regular expression validator for a specified column. This can be called multiple times to evaluate different patterns.

This function accepts two parameters.

Parameters

Name Data Type Description
ColumnNameString String Column Name to set the custom pattern.
RegularExpressionString String This is the regular expression to validate the column.


Syntax profiler->SetColumnCustomPattern(ColumnNameString, RegularExpressionString);
C integer = mdProfilerSetColumnCustomPattern(profiler, ColumnNameString, RegularExpressionString);
.Net integer = profiler.SetColumnCustomPattern(ColumnNameString, RegularExpressionString);


SetColumnValueRange

Optional. This SetColumnValueRange function sets the upper and lower bound for the specified column.

This function accepts three parameters.

Parameters

Name Data Type Description
columnNameStr String Column Name to set the value range.
fromStr String Lower bound value.
toStr String Upper bound value.


Syntax profiler->SetColumnValueRange(columnNameStr, fromStr, toStr);
C integer = mdProfilerSetColumnValueRange(profiler, columnNameStr, fromStr, toStr);
.Net integer = profiler.SetColumnValueRange(columnNameStr, fromStr, toStr);


SetColumnDefaultValue

Optional. This function sets the default value to the specified column.

This function takes two parameters

Parameters

Name Data Type Description
ColumnName String Column Name to set the default value.
DefaultValue String This is the default value of the column.


Syntax profiler->SetColumnDefaultValue(columnNameStr, defaultValueStr);
C integer = mdProfilerSetColumnDefaultValue(profiler,columnNameStr,defaultValueStr);
.Net integer = profiler.SetColumnDefaultValue(columnNameStr, defaultValueStr);

This function takes two parameters

Parameters

Name Data Type Description
ColumnName String Column Name to set the size.
ColumnSize Integer This is the size of the column.


Syntax profiler->SetColumnSize(ColumnNameStr, sizeValue);
C mdProfilerSetColumnSize(profiler, columnNameStr, sizeValue);
.Net profiler.SetColumnSize(columnNameStr, sizeValue);


SetColumnPrecision

Optional. This function sets the precision for a specified column. This applies to only ColumnTypeNumeric, ColumnTypeDecimal, ColumnTypeCurrency. Precision is the number of digits maximum allowed for that number. This function takes two parameters.
