[sqlite] Determine if UPDATE has worked.
Hi List,
I am new to sqlite and having trouble determining if an update has worked.
I am using the C/C++ API.
For an update, when sqlite3_step is executed it returns SQLITE_DONE when
a record is updated or if a record does not exist. I have not found an
answer by reading and searching the documentation and searching the
internet
This is the same for the command line tool.
Using code based on "http://www.sqlite.org/cvstrac/wiki?p=SimpleCode;
$ fred testdb "create table bob(p1 text PRIMARY KEY, p2 text)"
SQLITE_DONE: 101 : unknown error
$ fred testdb "insert into bob (p1, p2) values('foo', 'sue')"
SQLITE_DONE: 101 : unknown error
$ fred testdb "insert into bob (p1, p2) values('foo', 'sue')"
Error: 19 : constraint failed
$ fred testdb "update bob set p2 = 'fred' where p1 = 'foo'"
SQLITE_DONE: 101 : unknown error <-- update ok
$ fred testdb "update bob set p2 = 'fred' where p1 = 'fo1'"
SQLITE_DONE: 101 : unknown error <-- update fail
$ fred testdb "select count(*) from bob"
count(*) = 1
SQLITE_DONE: 101 : unknown error
$ fred testdb "select * from bob"
p1 = foo
p2 = fred
SQLITE_DONE: 101 : unknown error
$
When using the command line tool.
SQLite version 3.6.16
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> create table bob(p1 text PRIMARY KEY, p2 text);
sqlite> .header on
sqlite> .show
