In SQLite, there isn't a function called the now function, but rather "now" is a timestring parameter that is used in various SQLite functions to retrieve the current date and time. This may seem a bit confusing at first, since other SQL databases have a built-in function whose purpose is to return the current date and time.After creating a new row in a table that uses AUTOINCREMENT to create the PRIMARY KEY, one may wish to determine the value of the new row-id, for example if the value is need for a new row in a related table that will be inserted next. ...

The last_insert_rowid() SQL function is a wrapper around the sqlite3_last_insert_rowid() C/C++ interface function.. Update: you can use RETURNING in SQLite 3.35:The INSERT command is used to create new rows in the specified table. The INSERT works on a single table, and can both insert one row at a time or many rows at once using a SELECT command.Then the only way to get the last inserted record's ID is to issue a special query: select last_insert_rowid(). And this query needs to be issued right after the insert statement.does laser hair removal cause cancer -fc
