eval

I'm looking for a way to evaluate price expressions stored in database in Postgres 9.1+ I tried code below from answer in How to evaluate expression in select statement in Postgres but got error ERROR: missing FROM-clause entry for table "product" LINE 1: select product.price*0.95 how to fix ? Maybe it is possible to pass customer and product current row as eval parameters and to use them in eval expresion ? create or replace function eval( sql text ) returns text as $$ declare as_txt text; begin execute 'select ' || sql into as_txt ; return as_txt ; end; $$ language plpgsql; create table

I have a trained model which I am loading using CNTK.load_model() function. I was looking at the MNIST Tutorial on the CNTK git repo as reference for model evaluation code. I have created a data reader (which is a MinibatchSource object) and trying to run model.eval(mb) where mb = minibatch_source.next_minibatch(...) (Similar to this answer ) But, I'm getting the following error message Traceback (most recent call last): File "LID_test.py", line 162, in <module> test_and_evaluate() File "LID_test.py", line 159, in test_and_evaluate predictions = model.eval(mb) File "/home/t-asbahe/anaconda3

In the legacy codebase that I am working on, there is a condition evaluator which accepts user input to build a condition. This condition is then evaluated at run-time using php eval(). What is the best way to resolve this without using eval. For e.g. I have a condition "1>0" entered by the user in the UI. This has to evaluated and the result (true in this case) returned. Any suggestions? Let know if the problem seems vague, I would try and explain better. The evalMath parser over on PHPClasses provides a safe framework for evaluating this type of expression. I'd say the pattern most suited

This question already has answers here : How do I safely “eval” user code in a webpage? (4 answers) Closed 5 years ago . I need to eval() the code inside my page because I am working on something jsFiddle-like. Since eval has such a bad reputation, how can I interpret the user input code safely and securely? Or as safely and securely as possible? I would suggest you have a look at the following resources: https://code.google.com/p/jsreg/ https://www.owasp.org/index.php/OWASP_JavaScript_Sandboxes http://www.thespanner.co.uk/2012/10/18/mentaljs-sandboxparser/ Anyway, you should consider running

写在前面 本小菜鸡开学(其实已经开始了)就要面临找实习的压力了。所以在此开一贴记录一下搜集的前端面试的问题和自己即将被拷问的问题= =。悔不该当初没有好好学习quq！努力！ 面试题目总结 HTML 1.html5新增了哪些内容或api，使用过哪些？ HTML5新增input输入类型： email类型 url类型 number类型提供选择数字的功能，其中min属性设定最小值，max属性设定最大值，value属性设置当前值，step属性设定每次增长值。 range类型，表示限制数字输入的范围域 日期和时间类型:date,month,week,time,datetime,datetime-local search类型 tel类型 color类型 HTML5新增表单元素 datalist 规定输入域的选项列表 keygen提供一种可靠方法来验证用户 output用于不同类型的输出 还有更多细节内容不列在这里啦。请看 这篇博客 2.input和textarea的区别? <input type= "textarea">是单行文本框。<textarea>是多行文本框。 3.用一个div模拟textarea的实现？ 首先我们需要知道div是高度自适应的，高度会随着内容的增加而增加。而textarea有着固定的大小，高度超过规定高度就会出现滚动条。 div有一个属性叫做contenteditable
