QSqlQuery Insert multiple rows (MySQL)

[juansta_-]

MySql allows for insertion of multiple rows using a single INSERT INTO statement,

INSERT INTO table(c1,c2,...)
VALUES 
   (v11,v12,...),
   (v21,v22,...),
    ...
   (vnn,vn2,...);

Is there any way to duplicate this using QSqlQuery? At the moment I can only...

• Add rows one-at-a-time
• Prepare my own long INSERT INTO statement (Using QString)

I was hoping this could be handled by adding a std::vector (or other valid container type) during the bindValue method call... Is this possible?

See https://doc.qt.io/qt-5/qsqlquery.html#execBatch - don't know if the driver supports it.
But using a transaction + a simple loop will do the same. It will be a little bit slower I would guess but as long as you don't insert thousands of rows it's not measurable.
