How do you create a sql query of dynamic fields using a final string in VoltDB?
문제
I want to create a sql query of dynamic fields that are decided at runtime, such as:
SELECT some, random, field FROM table WHERE id = ?
Because there is a restriction that you must declare an instance variable SQLStmt:
public final SQLStmt sql = new SQLStmt("SELECT field0, field1 FROM table WHERE id = ?");
Since all fields are hard-coded or else VoltDB will not compile, I cannot set the fields I want to read.
So, How do you create a sql query of dynamic fields using a final string in VoltDB?
