Question

I have a Table:

| USERNAME | FORNAME | SURNAME | TELNUMBER | ZIPCODE ....

and I want to search username forename and surname in 1 query / statement .. and I don’t want multiple lines ..
like.. lets say ..

username : maria33
forname : maria

so this should be 1 row .. when I search mar%

and not 2!

Answer 1

As a prepared statement:

SELECT *
FROM   users
WHERE  username LIKE ?
    OR forname  LIKE ?
    OR surname  LIKE ?

Then if you fill in all three parameters with the same string, "%mar%":

preparedStatement.setString(1, "mar%");
preparedStatement.setString(2, "mar%");
preparedStatement.setString(3, "mar%");

You’d end up with this SQL statement:

SELECT *
FROM   users
WHERE  username LIKE "mar%"
    OR forname  LIKE "mar%"
    OR surname  LIKE "mar%"
