BigQuery's LIKE Operator Now Supports Underscores for Single Character Match

The LIKE operator in BigQuery is used for pattern matching within strings. It allows users to define a pattern to match against string values in a BigQuery table. The operator utilizes special wildcard characters to define the patterns.

In BigQuery, when using the LIKE operator, you can use the underscore _ to match a single character or byte. However, it's important to note that when underscores are used in keys, they will not be treated as literal underscores but as a placeholder for any character.

To escape special characters such as backslashes, underscores, or percent signs when using the LIKE operator in BigQuery, you can use the backslash \ character. For example, to search for an actual underscore, you would use \_. Additionally, you can prefix your string with r to create a raw string, which avoids the need to duplicate every single backslash.
