需要处理其内部有

Question

我有两个疑问这将插入一个报价的名称和

insertSQL = "insert into LineManager(LINEMANAGERID,LINEMANAGERNAME,BUSINESSGROUPID,STATUS) VALUES('" + lineManager.getLineManagerID() + "','" + lineManager.getLineManagerName() + "','" + lineManager.getBusinessGroupID() + "','" + lineManager.getStatus() + "')"; 

updateSQL = "update LineManager set BUSINESSGROUPID ='" + lineManager.getBusinessGroupID() + "' , LINEMANAGERNAME ='" + lineManager.getLineManagerName() + "' , STATUS ='" + lineManager.getStatus() + "' where LINEMANAGERID='" + lineManager.getLineManagerID() + "'"; 

到目前为止，这是工作的罚款为正规名称更新DB-，但是当面临问题LineManager名字就像''多克尼达先生'，多米尼克先生'。它在执行期间抛出异常。

任何人都可以帮助解决这个问题吗？

使用bind variables：

QSqlQuery query; 
query.prepare("insert into LineManager(LINEMANAGERID,LINEMANAGERNAME,BUSINESSGROUPID,STATUS) VALUES(:id,:name,:groupid:status)"); 
query.bindValue(":id",  lineManager.getLineManagerID()); 
query.bindValue(":name", lineManager.getLineManagerName()); 
query.bindValue(":groupid", lineManager.getBusinessGroupID()); 
query.bindValue(":status", lineManager.getStatus()); 
query.exec();
