Question

这是我的代码：

Dim job As String = TextBoxJobNum.Text
    Dim idws As Integer

sqlQuery =“UDATE Equipment SET JobHistory = JobHistory +'”＆amp;工作与“'WHERE ID ='”＆amp; idws＆amp; “'”

        Dim sqlCmd1 As New SqlCommand(sqlQuery, sqlConn)

        If sqlConn.State = ConnectionState.Closed Then sqlConn.Open()
        For Each row As DataGridViewRow In DataGridViewEquip.Rows
            idws = CInt(row.Cells(0).Value)
            sqlCmd1.ExecuteNonQuery()
        Next
        If sqlConn.State = ConnectionState.Open Then sqlConn.Close()

我收到错误“'='附近的语法错误”我到处搜索但似乎无法找到正确此行的语法。任何帮助将不胜感激。

在我看来，你只是在“更新”一词中错过了一个“P”

sqlQuery = "UPDATE Equipment SET JobHistory = JobHistory+'" & job & "' WHERE ID = '" & idws & "'"

另外，我建议不要使用字符串连接设置参数，而是使用parameters on a SqlCommand object。这样做的原因是减少了潜在的问题，例如额外的转义（例如“作业”变量包含“'”）或SQL注入。
