以下是我的查询:
def getdata1 = sql.rows("select student_id,school_grade_class_id from class_assign")
如何从
student_id
获取getdata1
?更新:
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**")
我应该从
alue of school_grade_class_id
将x替换为resultset v getdata1
。我该怎么办?
最佳答案
您可以执行以下操作:
getdata1.each{
println it.student_id
}
要么
sql.eachRow("select student_id,school_grade_class_id from class_assign", {
println it.student_id
})
