Question

我想通过将列“ ColName”中的字符串替换为以下内容来更新访问数据库表“ TableName”：

 Dim Sql As String = "UPDATE [" & TableName & "] SET [" & ColName & "] = REPLACE([" & ColName & "], '" & OldPart & "', '" & NewPart & "')"  
 Dim Cmd As new OleDbCommand
 Cmd.Connection = My data bsae connection string
 Cmd.CommandType = CommandType.Text
 Cmd.CommandText = Sql
 Cmd.ExecuteNonQuery()

我收到以下错误：

条件表达式中的数据类型不匹配。

我的代码有什么问题？

您可能有一些空字段，请尝试以下操作：

Dim Sql As String = "UPDATE [" & TableName & "] SET [" & ColName & "] = REPLACE([" & ColName & "], '" & OldPart & "', '" & NewPart & "') WHERE [" & ColName & "] Is Not Null"

Access数据库表更新替换
