Questions:

What is the equivalent of this SQL statement in django?

SELECT * FROM table_name WHERE string LIKE pattern;

How do I implement this in django? I tried

result = table.objects.filter( pattern in string )

But that did not work. How do i implement this?

Answers:

Use contains or icontains:

result = table.objects.filter(string__contains='pattern')

Questions:
Answers:

contains and icontains mentioned by falsetrue make queries like SELECT ... WHERE headline LIKE '%pattern%

Along with them, you might need these ones with similar behavior:
startswith, istartswith, endswith, iendswith

making

SELECT ... WHERE headline LIKE 'pattern%

or

SELECT ... WHERE headline LIKE '%pattern

result = table.objects.filter(string__icontains='pattern')

Case insensitive search for string in a field.
