ColumnComparisonCondition

Signature

class great_expectations.expectations.row_conditions.ColumnComparisonCondition(
 *,
 type: Literal['column_comparison'] = 'column_comparison',
 column: great_expectations.expectations.row_conditions.Column,
 operator: great_expectations.expectations.row_conditions.Operator,
 other_column: great_expectations.expectations.row_conditions.Column
)

Condition representing the comparison of two columns in the same row.

Both sides are column references. Expressions, functions and casts are not supported, and a column name is passed to each engine as written, under that engine's own quoting rules.

A row whose value in either column is null is excluded under every operator, including !=. To keep such rows, combine this condition with is_null() on both columns in an explicit OrCondition.
