Table.SelectRowsWithErrors

Table

Returns rows that contain at least one error value, optionally limited to specified columns.

Syntax

Table.SelectRowsWithErrors(table as table, optional columns as nullable list) as table

Parameters

Name	Type	Required	Description
`table`	`table`	Yes	The table to inspect.
`columns`	`list`	No	Optional list of column names. Only errors in those columns qualify a row. If omitted, all columns are checked.

Return Value

table — A table containing only rows that have at least one error value.

Remarks

Table.SelectRowsWithErrors is the complement of Table.RemoveRowsWithErrors. It returns only the rows that contain at least one error, useful for auditing and diagnosing data quality issues after import or type conversion steps.

When columns is specified, only errors in those columns cause a row to be included. Errors in other columns are ignored.

Examples

Example 1: Return all rows that contain errors

let
    Source = #table({"ID", "Value"}, {{1, 10}, {2, error "bad"}, {3, 30}})
in
    Table.SelectRowsWithErrors(Source)

Result

	ID	Value
1	2	[Error]

Example 2: Only check a specific column for errors

let
    Source = #table({"ID", "Value"}, {{1, error "bad"}, {2, 20}, {3, error "bad"}})
in
    Table.SelectRowsWithErrors(Source, {"Value"})
