QString Formatting: Using Placeholders for Dynamic SQL Queries

This code snippet takes two variables ///'iter.key()///' and ///'iter.value()///' and formats them into a ///'QString///' with the specified format: ///'///'%1 like '%%2%' and ///'///'. //n//nThe ///'%1///' and ///'%2///' are placeholders that will be replaced by the corresponding variables passed to the ///'arg()///' function. //n//nFor example, if ///'iter.key()///' is ///'///'name///'///' and ///'iter.value()///' is ///'///'John///'/// ', the resulting ///'QString///' would be ///'///'name like '%John%' and///'///'.
