SQL Engine


As we know, when we create a view, we can use SQL Engine to excute it. I want to know the bellow quesions

1. what is the SQL Engine?

2. what the different operation hana will do when we choose sql engine or not?

3. If we do a projection which includes a VARCHAR field and we use SQL Engine, we can activate it but when we do data preview , the error 266 inconsistent data type: VARCHAR or NCLOB are invalid function argument types.
