SQL wildcard characters are used for substituting one or more characters in a string. Wildcard operators or you can say characters are used with LIKE operators. The like operator is used with where clause for searching some specified pattern from a column. If you are unfamiliar with SQL datatype then check out my  SQL Datatypes example on this blog.

The Types of SQL wildcard operators are the following.

1. %

2) _

3. [char list]

The percent sign represents zero, one or multiple characters. The underscore represents a single number or a character. These symbols can be used in combinations.
