Archived:Complete SQL database guide for PySymbian
There are two database interfaces in PyS60, e32Dbm and e32Db.
e32Dbm is required for dictionary functions only (code example here Database in PyS60). Whereas, e32db allows further SQL processing as will be shown here.
#initiate database objects
#open database, if not exist, then create the file
#to create ur table
db.execute(u"create table table1 (id count,forename varchar, surname varchar)")
#contains three fields
#to insert data
db.execute(u"insert into table values(1,'joe','bloggs')")
#notice, the 1 is required to increment the key!
#to fetch the whole dataset
dbv.prepare(db,u"select * from table1")
for i in range(1,dbv.count_line()+1): #1 to number of rows
dbv.get_line() #grabs data from the currently selected row
for i in range(1,self.dbv.col_count()+1):
print dbv.col(i) #prints each column data
dbv.next_line() #selects the next row
- use db.execute(unicode(sql statement)) to perform insert/update/delete
- use dbv.prepare(db,unicode(sql statement)) to fetch data
This is only a framework for you to use. There are many ready-to-use classes available on other sites, if you prefer, but its less erroronous if you understand the code yourself.
