PHP和SQL的新功能，试图使语法正确

Sub MultiDArray()

    ' Define variables
    Dim arrayColumns As Integer
    Dim arrayRows As Integer
    Dim constants() As Integer
    Dim initialRow As Integer
    Dim initialColumn As Integer
    Dim rowCounter As Integer
    Dim columnCounter As Integer

    ' Define how many rows
    arrayRows = 4

    ' Define how many columns
    arrayColumns = Range("B3").Value

    ' Define row to begin gathering data
    initialRow = 7

    ' Define column to begin gathering data
    initialColumn = 2

    ' Redimension array to number of rows and columns
    ReDim constants(1 To arrayRows, 1 To arrayColumns)


    ' Loop through each row
    For rowCounter = 1 To arrayRows

        ' Loop through each column
        For columnCounter = 1 To arrayColumns

            ' Gather data into array
            constants(rowCounter, columnCounter) = Cells(rowCounter + initialRow, columnCounter + initialColumn)

            ' For debugging purposes
            Debug.Print "Cell: " & Cells(rowCounter + initialRow, columnCounter + initialColumn).Address, "Row: " & rowCounter, "Column: " & columnCounter, "Value:" & constants(rowCounter, columnCounter)

        Next columnCounter

    Next rowCounter

End Sub

会话带来的用户ID

这是我要纠正的查询

<?php
include("php/functions.php");
$userId = $_SESSION['userID'];
include("connections/conn.php");
?>

在重复键更新查询has slightly different syntax上：

INSERT INTO  selfesteemscore (
      selestscore
    , UserID
) VALUES(
      'NEW VALUE'
    , 'NEW USER ID VALUE'
)
ON DUPLICATE KEY UPDATE 
      selestscore = 'NEW VALUE'
    , UserID = 'NEW USER ID VALUE'
;

或者更好的是，不要重复两次新值：

INSERT INTO  selfesteemscore (
      selestscore
    , UserID
) VALUES(
      'NEW VALUE'
    , 'NEW USER ID VALUE'
)
ON DUPLICATE KEY UPDATE 
      selestscore = VALUES(selestscore)
    , UserID = VALUES(UserID)
;

警告：请阅读有关SQL注入和转义值或使用粗略语句的信息。

P.S。您初始化变量$ userId，但稍后使用变量$ userID

试图在DUPLICATE查询中修复此INSERT UPDATE
