After using quoteInto Am I safe from SQL injection?

Hello I am using quoteInto in my query like below

 $select->from('users')
 ->where($adapter->quoteInto('eu.username LIKE ?',"%".$param['name']."%"));

When I pass any thing like 'or -1=-1' or any think like

 ' or 1=1--
 ' or 1--
 ' or 1
 \" or '1'
 ' or 1=1--
 ' OR ''='
 ' or 'a'='a
  ') or ('a'='a
'; exec master..xp_cmdshell 'ping 10.10.1.2'--
 ';

When I echo my query, all this stuff is put in LIKE clause of my query. I just want to ask that after quoting my query is safe from sql injection?

Yes, you are safe from SQL injections by using the db adapter quote functions.

When you use quoteInto Zend will call Zend_Db_Adapter::quote method to escape the value string.

From Zend Docs:
The quote() method accepts a single argument, a scalar string value. It returns the value with special characters escaped in a manner appropriate for the RDBMS you are using, and surrounded by string value delimiters.

To make your application safer you should also use Zend_Form with elements utilizing available Zend Filters and Zend Validators. Validation of elements will catch the problem and avoid junk database calls and filters will sanitize your data!
