Recommended Book: Getting Started with No SQL The following code snippet queries all records from the Users table and print out details for each record: Retrieves value of the second column in the current row, which is the username field.
The value is casted to a String because we know that the username field is of type VARCHAR based on the database schema mentioned previously. "; Prepared Statement statement = conn.prepare Statement(sql); String(1, "123456789"); String(2, "William Henry Bill Gates"); String(3, "[email protected]"); String(4, "bill"); int rows Updated = statement.execute Update(); if (rows Updated String sql = "DELETE FROM Users WHERE username=?
In turn with update Row could be simpler to set certain columns and you are not forced to make quirky string manipulation to get the sql update statement right. So it depends on the quality of the database driver implementation.
If I remember well, My SQL driver will throw an Exception when using update in execute Query. So the use of one or of the other depends on the DBMS Driver, right?
