PreparedStatement with list of parameters in a IN clause [duplicate]

Answer 1

You can use :

for( int i = 0 ; i < listField.size(); i++ ) {
    i < listField.size() - 1 ? request.append("?,") : request.append("?");
}

Then :

int i = 1;
for (String field : listField) {
    statement.setString(i++, field);
}

Exemple :

List listField = new ArrayList();
listField.add("test1");
listField.add("test2");
listField.add("test3");

StringBuilder request = new StringBuilder("SELECT * FROM TABLE WHERE FIELD IN (");

for( int i = 0 ; i < listField.size(); i++ ) {
    request = i < (listField.size() - 1) ? request.append("?,") : request.append("?");
}


DNAPreparedStatement statement = DNAPreparedStatement.newInstance(connection, request.toString);

int i = 1;
for (String field : listField) {
    statement.setString(i++, field);
}

ResultSet rs = statement.executeQuery();
