Question

我无法在这里获得语法;是否有一些更广泛的POCO-SQLite示例？

我得到一个Poco :: exception， sendErrorResponse HTTP_INTERNAL_SERVER_ERROR

                    Poco::Data::SQLite::Connector::registerConnector();
                    // create a new session
                    Session updsession("SQLite", managers);
                    facilities UnitFacility;

                    Statement updateRecord(updsession);

                    updsession << "UPDATE facilities SET name = nameString, address = addressString, phone = phoneString WHERE facilityNumber = 3;";
                    updateRecord.execute();

//更新：简化有或没有[]仍然没有去。

                    Poco::Data::SQLite::Connector::registerConnector();
                    Session updsession("SQLite", managers);
                    Statement updateRecord(updsession);
                    updsession << "UPDATE facilities SET Name = 'Frank' WHERE [FacilityNumber = 1];",now;
                    updateRecord.execute();

Answer 1

两个SQL查询都无效。

原始查询：

UPDATE facilities SET name = nameString, address = addressString, phone = phoneString WHERE facilityNumber = 3

结果：

no such column: nameString: UPDATE facilities SET name = nameString, address = addressString, phone = phoneString WHERE facilityNumber = 3

修正查询：

UPDATE facilities SET name = 'nameString', address = 'addressString', phone = 'phoneString' WHERE facilityNumber = 3

结果：

Query executed successfully: UPDATE facilities SET name = 'nameString', address = 'addressString', phone = 'phoneString' WHERE facilityNumber = 3 (took 0ms, 1 rows affected)

原始查询：

UPDATE facilities SET Name = 'Frank' WHERE [FacilityNumber = 1]

结果：

no such column: FacilityNumber = 1: UPDATE facilities SET Name = 'Frank' WHERE [FacilityNumber = 1]

修正查询：

UPDATE facilities SET Name = 'Frank' WHERE FacilityNumber = 1

结果：

Query executed successfully: UPDATE facilities SET Name = 'Frank' WHERE FacilityNumber = 1 (took 0ms, 1 rows affected)

目前尚不清楚这个问题与HTTP有什么关系。
