If I'm not using prepared statements to tend to use something like:

String statement = "update users set name='" + encode(name) + "'";

Where encode is defined as:

/**
* Encode a string suitable for being placed in a query.
*/
final String encode(String dirtyString) {
StringBuffer cleanString = new StringBuffer("");
for (int i = 0; i < dirtyString.length(); i++) {
char c = dirtyString.charAt(i);
cleanString.append(c);
if (c == '\'') {
cleanString.append(c);
}
}
return cleanString.toString();
}

Hope this helps,
