如何创建一个新表并将其导出为csv？

Question

假设我将此作为我的sql脚本。 我实际上如何创建一个新表，以便可以导出为csv？

SELECT *

FROM `db`.tableParent1

INNER JOIN tableParent2
ON tableParent1.req_id=tableParent1.req_id

INNER JOIN tableParent3
ON tableParent1.req_id=tableParent3.req_id

UNION ALL

FROM `db`.tableChild1

INNER JOIN tableChild2
ON tableChild1.req_id=tableChild2.req_id

INNER JOIN tableChild3
ON tableChild1.req_id=tableChild3.req_id

要通过查询创建新表，您需要输入“将表名称创建为QUERY”

Dim ArrayCount As New List(Of Integer)
            Dim x As Integer, y As Integer
            For x = 0 To TwoDeeArray.GetUpperBound(0)
                For y = 0 To TwoDeeArray.Rank - 1
                    If TwoDeeArray(x, y) >= ArrayCount.Count Then
                        Do While TwoDeeArray(x, y) >= ArrayCount.Count
                            ArrayCount.Add(0)

                        Loop
                    End If
                    ArrayCount(TwoDeeArray(x, y)) += 1
                Next
            Next
