What are the wildcard characters that are used with the LIKE command? Provide one or more examples of each
The LIKE special operator is used in conjunction with wildcards to find patterns within string attributes. Standard SQL allows a user to use the percentage sign (%) and underscore (_) wildcard characters to make matches when the entire string is not known:
% means any and all following or preceding characters are eligible. For example:
'J%' includes Johnson, Jones, Jernigan, July, and J-231Q.
'Jo%' includes Johnson and Jones.
'%n' includes Johnson and Jernigan.
_ means any one character may be substituted for the underscore. For example:
'_23-456-6789' includes 123-456-6789, 223-456-6789, and 323-456-6789.
'_23-_56-678_' includes 123-156-6781, 123-256-6782, and 823-956-6788.
'_o_es' includes Jones, Cones, Cokes, totes, and roles.
