sqlite newbie questions

[kf9150 at gmail.com]

Hello,

I have a sqlite database table which has a table named "Transmittal".
Before inserting a new record into the database, i'd like to perform
some checking. How do i select all records with certain value (say
"Smith") for a column (say "Last_Name")? Knowing almost nothing about
SQL, i just selected everything and process the returned list.

cur.execute('select * from Transmittal')
records = cur.fetchall()

Also, how do i delete records with certain value for centain column. I
was thining of something like
cur.execute('delete * from Transmittal where Last_Name=?', "Smith")
but the syntax it's not correct.

Thanks for your help.
