如何在grails中获取结果集数据

Question

Below is my query:

def getdata1 = sql.rows("select student_id,school_grade_class_id from class_assign")

How do I get student_id from getdata1 ?

UPDATE:

def getdata1 = sql.rows("select student_id,school_grade_class_id from class_assign")


def getdata2 = sql.rows("select class_id,class_name,school_grade_id from class_rel where school_grade_class_id=**x**")

I should replace x to resultset v alue of school_grade_class_id from getdata1 . What should i do?

Answer 1

You can do something like this:

getdata1.each{
    println it.student_id
}

Or

sql.eachRow("select student_id,school_grade_class_id from class_assign", {
   println it.student_id
})
