这是很方便操作sqlite的easy sqlite c++操作库,开源,供大家学习一下
//define table structure
Field definition_tbPerson[] =
{
Field(FIELD_KEY),
Field("fname", type_text, flag_not_null),
Field("lname", type_text, flag_not_null),
Field("birthdate", type_time),
Field(DEFINITION_END),
};
//define database object
sql::Database db;
try
{
//open database file
db.open("test.db");
//define table object
Table tbPerson(db.getHandle(), "person", definition_tbPerson);
//remove table from database if exists
if (tbPerson.exists())
tbPerson.remove();
//create new table
tbPerson.create();
//define new record
Record record(tbPerson.fields());
//set record data
record.setString("fname", "Jan");
record.setString("lname", "Kowalski");
record.setTime("birthdate", time::now());
//add 10 records
for (int index = 0; index < 10; index++)
tbPerson.addRecord(&record);
//select record to update
if (Record* record = tbPerson.getRecordByKeyId(7))
{
record->setString("fname", "Frank");
record->setString("lname", "Sinatra");
record->setNull("birthdate");
tbPerson.updateRecord(record);
}
//load all records
tbPerson.open();
//list loaded records
for (int index = 0; index < tbPerson.recordCount(); index++)
if (Record* record = tbPerson.getRecord(index))
sql::log(record->toString());
sql::log("");
sql::log("ALL OK");
} catch (Exception e) {
printf("ERROR: %s\r\n", e.msg().c_str());
