Question

I am using jdbc to select data from a mysql database. I am performing a search query,

stmt.executeQuery("SELECT (NAME) FROM tablename WHERE FULLNAME LIKE '"+"a string'"");

How do I perform a case and whitespace insensitive search?

Answer 1

within the query you can use the function lower() to convert the string to lower case or upper() to convert the string to UPPER CASE and trim() to remove excessive spaces at beginning and end.

Your query will look something like this

stmt.executeQuery("SELECT (NAME) FROM tablename WHERE LOWER(FULLNAME) LIKE TRIM(LOWER('"+"a string"'))");
