Suppose I have various email addresses all containing an underscore like gm_ace@where.com, hj_bus@ where.com, etc.How can I search for those particular emails?
If I use a WHERE clause such as 'WHERE eMail LIKE '%_' it returns all rows. 'WHERE eMail LIKE 'gm_%' returns rows that do not contain an underscore. Can you offer any suggestions?
The underscore character is a single character wildcard in the same way the percent sign is a multi-character wildcard. To query for an underscore character you need to wrap the underscore in square brackets:
WHERE email LIKE 'gm[_]%'
If you want to search for all email addresses with a two character value then an underscore, this WHERE clause would work:
WHERE email like '__[_]%@%'
