I got and address book with names of people. I use the following code to perform a search in the name column:
register = []
text = "{0}%" .format(self.lineEdit_6.text())
c.execute("select id, name from contacts where nome like '{0}'" .format(text))
for row in c:
register.append(row)
self.listWidget_4.addItem(str(row[1]))
self.listWidget_6.addItem(str(row[0]))
if register == []:
self.listWidget_4.addItem("No result")
The name column has the name and the surname ( like, John Smith) The code above works fine when i don't remember the entire name but just the starting letters. But I want that the results show all the matches, not only at the beginning of the names. So, if I got 3 names (Simonne Welsh, Adam Loyd, John Smith) and a type the letter S it has to give the result of the names Simone Welsh and John Smith. How do I do that?
Do this:
text = "%{0}%" .format(self.lineEdit_6.text())
c.execute("select id, name from contacts where nome like '{0}'" .format(text))
(include the wildcard before the match string as well as after).
Also, please consider using ( note: corrected this syntax ):
c.execute("select id, name from contacts where nome like ?", [text])
or
c.execute("select id, name from contacts where nome like ?", (text, ))
which will:
Make your code safe from SQL injection attacks.
Correctly handle cases in which the text
includes special characters, like a single quote (for instance, name of O'Reilly
).
