Understanding Wildcard Search in Snowflake

Wildcard search is a powerful tool for searching through large amounts of data in Snowflake. It allows you to search for specific patterns in your data, making it easier to find the information you need. In this article, we'll take a look at how wildcard search works in Snowflake and how it can be used to quickly find the data you need.

What is Wildcard Search?

Wildcard search is a type of search that uses special characters to match patterns in data. It is commonly used in databases to quickly search through large amounts of data. In Snowflake, wildcard search is used to search for specific patterns in strings, such as words, numbers, or characters.

Wildcard search in Snowflake uses two special characters: the asterisk (*) and the question mark (?). The asterisk is used to match any number of characters, while the question mark is used to match a single character. For example, if you wanted to search for all words that start with the letter "a", you could use the wildcard search "a*".

Examples of Wildcard Search in Snowflake

Let's look at a few examples of how wildcard search can be used in Snowflake. In the first example, we'll search for all words that start with the letter "a".


SELECT * FROM table WHERE column LIKE 'a%'

This query will return all rows in the table where the column starts with the letter "a".

In the second example, we'll search for all words that contain the letter "a".


SELECT * FROM table WHERE column LIKE '%a%'

This query will return all rows in the table where the column contains the letter "a".
