示例1: main
int main() {
DatabaseConnection db;
try {
db.execute(const_cast<char *>("SELECT * FROM test2;"));
// Example: Listing all columns from executed query
cout << "Lists all columns from table" << endl;
list<string> columns = db.getColumns();
for(list<string>::iterator i = columns.begin(); i != columns.end(); i++)
cout << (*i) << endl;
// Example: Extracting specific data types into acceptable data types
cout << endl << "Extract specific data types" << endl;
int intTest = db.getInt(const_cast<char *>("intTest"));
double doubleTest = db.getDouble(const_cast<char *>("doubleTest"));
int numericTest = db.getInt(const_cast<char *>("numericTest"));
string blobTest = db.getText(const_cast<char *>("blobTest"));
string textTest = db.getText(const_cast<char *>("textTest"));
cout << "INT: " << intTest << endl;
cout << "DOUBLE: " << doubleTest << endl;
cout << "NUMERIC: " << numericTest << endl;
cout << "BLOB: " << blobTest << endl;
cout << "TEXT: " << textTest << endl;
// Resets the pointer back to the beginning
db.reset();
// Example: Extract any type of data types
cout << endl << "Extract any type of data types" << endl;
cout << "NUMERICTEST: " << db.getColumn(const_cast<char *>("numericTest")) << " TEXTTEST: " << db.getColumn(const_cast<char *>("textTest")) << endl;
// Got new set of data. Why? Because I can.
db.finalize();
db.execute(const_cast<char *>("SELECT * FROM test;"));
// Example: Extract all data obtained from executing the query
cout << endl << "Extract all data from query and store in a list of multimaps" << endl;
list<multimap<string, string> > results = db.fetchAll();
list<multimap<string, string> >::iterator rows = results.begin();
while(rows != results.end()) {
multimap<string, string>::iterator row = (*rows).begin();
while(row != (*rows).end()) {
cout << (*row).first << " " << (*row).second << " ";
row++;
}
cout << endl;
rows++;
}
} catch (DatabaseConnectionException e) {
cout << e.getMessage();
}
// Deletes pointer to query
db.finalize();
// Deletes pointer to database connection
db.close();
return 0;
