I was a bit stumped by this one not long ago so here is an example of correctly binding a value to a
LIKE clause inside a
SQL statement with
Java.
First, however, lets see the incorrect way that does not work...If you define your
SQL statement to have the bind value and a
LIKE wildcard, the
JDBC engine will not be able to process it.
The above code throws this kind of exception...
The correct way to do it is to treat the bind variable for the
LIKE statement just as you would any other bind variable. The code then looks like this...
Note that the
SQL string itself does not have the
LIKE wildcard. The wildcard is defined when you bind the variable using the
setString() method instead.
