Is it possible to bind a column for every row of dataset 1 as parameter for dataset 2 ?

hi，

    you can use dataset formula to get all values in one column https://help.fanruan.com/finereport/doc-view-850.html#3
    tablename.select(colname)

HI：

    According to your further description, I made a demo, you can refer to, [Because the data source used in the demo does not have SP, so I used the dataset for ds2; the dataset and SP have the same parameter transfer principle, you can refer directly]
