SELECT * FROM SomeTable t WHERE NOT EXISTS (SELECT * FROM dbo.Split('John Smith', ' ') s WHERE t.NameColumn NOT LIKE '%' + s.Data + '%')
You'd need to see how... .

So, the word cat would knock out the sentence: String by the "|" character.
Array subtraction is your friend here:
words.each do |word| sentences -= sentences.grep(/#{word whitespace separated words in the sentence.

Edit: If you ....
Using;string>(); … myCollection.Add(aString);

Instead I would use a StringCollection.
] = "new string";
I would not use an array in this case.
