MySQL Connector C++ 调用存储过程

表  mydb.mytable
--------------------------------------------------------
|  sid(BIGINT)   |   Name(VARCHAR(50))  |

--------------------------------------------------------

【存储过程1】通过参数返回一条数据

CREATE DEFINER=`root`@`%` PROCEDURE `Query`(IN `skey` VARCHAR(50), OUT `oid` BIGINT, OUT `oname` VARCHAR(50))
	LANGUAGE SQL
	NOT DETERMINISTIC
	CONTAINS SQL
	SQL SECURITY DEFINER
	COMMENT ''
BEGIN
	select sid, Name into oid, oname from mydb.mytable where Name=skey limit 0,1;
END

Connector c++调用

Driver *pDriver = mysql::get_mysql_driver_instance();
try
{
	auto_ptr<Connection> pConnection(pDriver->connect("tcp://127.0.0.1:3306", "root", "123456"));
	auto_ptr<PreparedStatement>prepQuery(pConnection->prepareStatement(
		"call searchserver.query(?, @sid, @sname)" ));
	prepQuery->setString(1, "ABC");
	prepQuery->execute();

	auto_ptr<PreparedStatement>prepSelect(pConnection->prepareStatement(
		"select @sid as sid, @sname as sname"));
	auto_ptr<ResultSet>lpRes(prepSelect->executeQuery());
	int nRows = lpRes->rowsCount();
	while(lpRes->next())
	{
		uint64_t ID = lpRes->getUInt64(1);
		string strName = lpRes->getString(2);
	}
}
catch (SQLException& e)
{
	string str = e.what();
	return;
}


【存储过程2】默认返回记录集

CREATE DEFINER=`root`@`%` PROCEDURE `Query`(IN `skey` VARCHAR(50))
	LANGUAGE SQL
	NOT DETERMINISTIC
	CONTAINS SQL
	SQL SECURITY DEFINER
	COMMENT ''
BEGIN
	select sid, Name from mydb.mytable where Name like skey;
END

Connector c++调用

Driver *pDriver = mysql::get_mysql_driver_instance();
try
{
	auto_ptr<Connection> pConnection(pDriver->connect("tcp://127.0.0.1:3306", "root", "123456"));
	auto_ptr<PreparedStatement>prepQuery(pConnection->prepareStatement("call mydb.query(?)" ));
	prepQuery->setString(1, "A%");
	auto_ptr<ResultSet>lpRes(prepQuery->executeQuery());
	int nRows = lpRes->rowsCount();
	while(lpRes->next())
	{
		uint64_t ID = lpRes->getUInt64(1);
		string strName = lpRes->getString(2);
	}
}
catch (SQLException& e)
{
	string str = e.what();
	return;
}
