I have a very particular question related to thymeleaf in spring boot, using the Java Persitence API (JPA).
I have three tables (A, B, C), hence models, they look like this:

QUESTION
This is a scalar query, originally within a function. The result datatype varies, depending on which field I'm intresting of.
In this example, I expect a scalar result of datatype NVARCHAR 'Andy' but got an error:
Msg 245, Level 16, State 1, Line xx Conversion failed when converting the nvarchar value 'Andy' to data type int.
Is there any way to get around this?

Below is the SQL Query I am using in order to get some information. Within this information is an XML column. I am wanting to read this XML and parse out the needed ID inside the <> brackets. This query below does do that but I am looking for a cleaner way of doing it [if it exists]:

calls.
XML date type could be easily handled by the XQuery.

Answered 2021-Apr-17 at 10:36You are having this issue because there is be a possibility that composite keys (AID,AMARKET) and (BID,BMARKET) will not be unique when doing a join on keys AMARKET = BMARKET. Therefore you are getting the error not mapped to a single property
. Please bear with me, use the following sample data to analyze the issue;

QUESTION
I'm running Python pyodbc against SQL Server. I have a very complex query that I minimize here as
...ANSWER
Answered 2021-Feb-08 at 21:55Because your SQL connection driver does not seem to support proper parameters, it is embedding the parameter as text. I have no idea how good it's sanitizing and escaping method is, but it's not usually a good idea because of the risk of SQL injection.
I note that
pymssql
driver does support named parameters
What can happen is that when the compiler can see the exact value you want to use, it will calculate the statistics of how many rows are likely to match (the "cardinality"), and therefore it may choose a different access pattern based on what indexes are available.
When the value comes through as a proper parameter (when using a good SQL driver), the parameter is "sniffed", and the compiler will use the statistics based on the value in the first run of the query. This can be of benefit if there is a commonly-used value.
If the value is in a local variable, then parameter-sniffing is not used, and the compiler uses the average cardinality for that predicate. This may be better or worse than "sniffing".
It would sound like embedding the value is better. But this is not the case.
When the value is embedded, each query stand on it's own, and must be compiled again every time. This can have a big impact on execution time and CPU usage, as well as memory usage to save the query plans.
QUESTION
I have a startDateTime and endDateTime. I am trying to find the total difference between them in hours. I use DATEDIFF() to get the difference in hours, (but in minute format, so ten hours 30 min would be 630 min). I divided by 60 to get the total remainder (since using days was rounding to 1 based on boundary rules)
Start date looks like 2020-12-03 10:00:00.000, same with end date in terms of formatting

QUESTION
I have created two tables. The first table I name it atable and the second table I name it second . On the atable I have 3x3(3 columns x 3 rows) and on the second I have 1x9. I want to fill in the first table with numbers, I have created the begin() function so I will fill the table with random items,using a button named Start.Next, I have created a function named check(), it clicks on the first table(atable). Now, what I want to do is ,when I click on the table(atable) I want each of my clicking to transfer the number into the other table(named :second ).I have created the table second but I didn't find how to send the clicks from one table into the other table.
...ANSWER
Answered 2020-Dec-01 at 03:34So either I did this backward or this is how you wanted it. If you meant like, a long (height) table then this is what you want. If you want a wide table, just switch the secondTable.rows[mclics].cells[0].innerHTML = trgt.innerHTML
to secondTable.rows[0].cells[mclics].innerHTML = trgt.innerHTML
and reformat the table to only have one row. This code simply takes the innerHTML of the cell that you click and add it to the next table's next spot. There is no check though, so it will error once you fill-up the second table. Good luck!
