# ETL: ParseLongOrDefault

> Safely convert a string to a long integer, returning a default value if conversion fails. Use for resilient large number parsing in ETL pipelines.

## Description

Attempts to convert a string representation of a number to a long integer numeric equivalent. If successful, returns the string as a long integer value, otherwise returns the default value.

## Syntax

`ParseLongOrDefault(string_expression, default_value)`

## Arguments

*string\_expression* - string

*default\_value* - long

## Examples

`ParseLongOrDefault(string1,42L)` Using string1 as input

`ParseLongOrDefault('14607340342631',42L)` Will output: "14607340342631"

`ParseLongOrDefault('Universe',42L)` Will output: "42"

## Return value datatype

Long

## Impact of null value

If input is null, returns null.
