Question

我想删除我的sql中的记录，其中数组作为输入，带有两个where语句。我找不到像这样的陈述......

"DELETE FROM perpetualinventory WHERE productID= ".implode(',',$productID)" && expiryDate=".implode(',',$expiryDate);

建议的答案

 "DELETE FROM perpetualinventory WHERE productID IN (".implode(',',$productID)") AND expiryDate IN (".implode(',',$expiryDate).")";

语法错误，意外＆＃39;＆＃34;）AND expiryDate IN（＆＃34;＆＃39;（T_CONSTANT_ENCAPSED_STRING）

Answer 1

即使不建议您可以这样做

"DELETE FROM perpetualinventory WHERE productID IN (".implode(',',$productID).") AND  expiryDate IN (".implode(',',$expiryDate).")";

Answer 2

此代码应该有效：

export default class App extends Component {
   constructor() {
   super();
   this.onInputChange = this.onInputChange.bind(this);

   this.state = {
     rangeValue: 50
   }
 }

onInputChange(e) {
   this.setState({ rangeValue: e.target.value});
}

render() {
   var {rangeValue} = this.state;

  // this logs unbearably slow and I want to be able to pass this value 
  // to a child component as a prop as it updates
  console.log(rangeValue)

  return (
     <div className="map-controls">
        <input type="range" onChange={this.onInputChange}></input>
        <ExampleComponent rangeValue={this.state.rangeValue} />
     </div>

  );
 }
}

说明：

DELETE FROM perpetualinventory WHERE productID IN ('".implode($productID,"', '")."') AND expiryDate IN ('".implode($expiryDate,"', '")."')";
