QUESTION
I have a table in SQL Server 2008 database hosted on a shared web hosting. I cannot change the collation of the database because I don't have permissions.
When I created the table, I set the collation for the columns that I want but it doesn't do anything and I still see ???? when I query the table. I tried nvarchar as well and it didn't work.
The table:
...ANSWER
Answered 2021-Mar-25 at 20:05The problem is your INSERT/UPDATE statements. Unless you define those values as an nvarchar then the characters outside the databases collation will be lost. This means you need to declare your parameters as an nvarchar. As a result I would suggest, instead, not changing the collation of the columns and changing them as an nvarchar and using an nvarchars throughout your code.

I'm attempting to pass my ID variable to my edit function so I can POST my changes to my database. However, I'm receiving this error...
...ANSWER
Answered 2021-Jun-14 at 15:47In your template you're calling your method editData(item) and you're passing variable item as your parameter. But in your template there is no such thing defined - I assume (without looking at the rest of your code) that you wanted to write editData(forecast) instead. This will pass the forecast variable defined in your *ngFor directive.

Answered 2021-Jun-15 at 02:57you are almost there.. you just need to use the same logic to join to the product master table. However, since you need the total of quantity, you need to group by the other columns you select (but not aggregate).
The query will be something like this :
QUESTION
How do I create charts pulling from the database? I've tried MorrisJS, ChartJS, CanvasJS, HighCharts. But I think the closest I got is with ChartJS so hopefully we can stick to that.
I need to create a chart that pulls data from the db and using more than 1 table in the database, for example, Database name "Finance", I need a bar chart that compares sum of Amount in dbo.Revenue and Sum of Amount in dbo.Expense by month. Month is the x-axis. Something like this , but I did this manually by adding the values in the code.
What I have tried to do to pull from the db, ar is the table name (revenue)

QUESTION
the code that I have now updates the shadow table correctly but the only problem I'm having is that if the email value is the same it will still update the shadow table. This is not want i want. I need the shadow table to update only when the email is changed not updated how could i do this? example "email@email.com" original value should only update if the table changes that value to something different like "secoundemail@gmail.com"
...ANSWER
Answered 2021-Jun-14 at 22:48You need to compare the inserted and deleted tables to check if the data has actually been changed.
The easiest way to do this while still taking into account nulls, is to use EXCEPT. Make sure to compare against the same primary key.
Note that you can still use IF(UPDATE as an early bail-out condition, but it will only bail out if the column was not present at all. It won't work if the column is there but data did not change.
