QUESTION

HTML/JS Select onchange isn't working for some select items

Asked 2020-Apr-01 at 05:43

I am new to HTML and JS and a bit stumped at the moment trying to get a select tag to fire off onchange. From reading through SO questions, I know of two ways to do it. One being the onchange="script" field in the select tag. The other is via referencing the element ID in window.onload and calling selectItem.onchange.

Strangely neither is working for me on the 'firstSelect' select element in the following code even though they do work for the select tags above it. In fact I can't seem to reference any element ID below the tr that contains the 'hitter' select element; even if I copy the hitter row and simply change the id and name, it doesn't work. The ejs does seem to work just fine for all the selects.

For the firstSelect element, I have tried the window.onload (script in the head) and using onchange="firstSelected" in the select tag. Neither seem to have any effect.

I am sure that I've done some silly beginner thing or overlooked something, but would appreciate any help.

(For brevity in the post, I removed a bunch of link .css and script bootstrap tags, that I can add back if it's relevant.)

xUnit tests suddenly throwing exception System.Collections.Generic.KeyNotFoundException: Unable to find UniqueTest VSTestAdapter

Asked 2020-Jan-29 at 09:04

I have an xUnit project that has run all tests flawlessly until now.

I added two new test methods and now, suddenly, no tests can run because an exception is thrown:

System.Collections.Generic.KeyNotFoundException: Unable to find UniqueTest VSTestAdapter

Followed by a path to one of my test method, but sometimes when I, still, try to run all tests the method after the exception changes.

The kind of the exception leads me to think maybe the following code is related to the problem, but all tests ran fine after I wrote it, the problem appeared after I wrote two quite ordinary tests and commenting them does nothing.

Oracle: Setting Session Parameters in Packages and Procedures

Asked 2020-Jan-24 at 21:30

I'm a SQL Server DBA currently getting up to speed on Oracle. I'm trying to create something very similar to sp_WhoIsActive for SQL Server but for Oracle without reinventing the wheel. Essentially all I'm doing is selecting some values from v$session and inserting them into a table (poor man's ASH/AWR).

It would seem that in Oracle 12.1, there's a bug when querying dictionary views where it can take forever due to bad parsing logic (Bug 22225899 : SLOW PARSE FOR COMPLEX QUERY). The work-around is to set a session parameter:

alter session set "_optimizer_squ_bottomup"=false;

In T-SQL, I could very easily execute a stored procedure in-session and set this variable at runtime. However in Oracle, it wouldn't seem thats the case.

Sample Code:

Asked 2019-Dec-30 at 00:08

I'm trying to get proficient in generics in Java. I have some 100 entities that use the same findBy method in JPA interface. Almost all of them require a call to AwrSnapDetails so instead of adding @ManyToOne private AwrSnapDetails awrSnapDetails; to each Entity, I've created a HelperEntity class and using @Embedded annotation. Now I have gotten to the point in coding where I can't figure out what I am doing wrong and how to go about resolving this error.

does oracle hard parse whenever the text changes

Asked 2019-Nov-28 at 14:26

My understanding of hard parse in Oracle is, when a SQL statement is processed, if no matching text is found it will be hard parsed. I am working on an assignment, where they fire multiple SQL's from a service as below(around 50 variations executed multiple times)

...

ANSWER

Answered 2019-Nov-28 at 14:26

Yes.

When you submit a statement to the database, it hashes the text to produce a SQL_id. Meaning you have a cursor for each => there must have been a hard parse.

You can verify this by querying v$sql. This will have an entry for each version. You can also see the number of hard parses by checking the parse count (hard) stat:
