SQLite delete with table alias

I am trying to alias a table in SQLite, for example by the following command: (it is from the book i am reading"Database Management Systems by Ramakrishnan")

DELETE FROM Students S WHERE S.sid=12546

This code gives a syntax error. Without aliasing, the following code works:

DELETE FROM Students WHERE sid=12546

But, if i want to alias the table, what should i do? Can anyone help?

The DELETE statement operates on a single table and does not use a table alias. so you will have to use your query as :

DELETE FROM Students WHERE sid=12546

Update: SQLite apparently doesn't support joins with the delete statement, as you can see on the Syntax diagrams. In short in SQLite, one DELETE command deletes from only one table. So aliasing is of no use
