我正在使用 LabVIEW 和 Database Toolkit 来执行 SQL 查询，但出于语法原因，它一直对此表示不满。我通过 ODBC 连接器使用 MySQL。除最后一行外，每一行的末尾都应有一个换行符。

LabVIEW抛出的错误是这样的：

可能的原因：

ADO 错误：0x80040E14 Microsoft OLE DB Provider for ODBC Drivers 发生异常：[MySQL][ODBC 5.1 Driver][mysqld-5.1.42-community]您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以在 'UPDATE plc_addresses SET CurrValue = '0.00' WHERE Address = '1092' 附近使用正确的语法；在 NI_Database_API.lvlib 的第 2 行更新 plc_a':Conn Execute.vi->UpdatePLCAddressesTable.vi->DevelopSQL.vi

我认为您需要将这些作为单独的 SQL 语句发送，而不是一次发送所有这些语句。

ADO 不支持在单个操作中执行多个语句，您需要一个接一个地依次执行它们。鉴于它们都相似，您可能需要使用Prepared Statements。

根据Mimer Validator，您的 SQL 很好。我的猜测是，出于某种原因，它不喜欢分号。

启用 FLAG_MULTI_STATEMENTS
