Ah, ok. So the reason you may want to keep unit tests is if anything needs to change with your data model, you've already documented how things should work and...

In my opinion unit testing in a relational database is basically fruitless. The whole idea is the data model is schema bound. So what are you testing but only...

the non-SQL parts of our C# app are tested with a few unit tests and a lot of manual tests.
We plan to reverse the quantity (unit testing first and...

It's possible to get rid of "or" in where clause using DeMorgan's Law. If the goal is readable code tho... sometimes that pretty much goes out the window.
Some test data:

Last year I had to do something similar with a csv file. Openrowset can't contain sql expressions, only literal strings. So dynamic sql is the way to go. Something like:

Step 1: generate some dummy data
/* create a table to hold the country and province values */
/* as well as a column to store the cntry_prov_code...

If your database originally resided on a different server (with a different collation), columns created would have used that default. Columns created after the migration would default to the...

Why do you declare province to be char(2) and then assign it left(col_name, 1) which is only 1 character?
Does the sequence reset for each country?
What is the needed sort order...

Suppose the code you need to calculate is called the "Country Province Number" CPN. The issue here is the example you provided only declares variables for a single record and...

You have 2 tables?
The output...

The "or" we were looking for. The second example, the one with "coalesce", consolidates the 3 columns (Employed, Not employed, Retired) into 1 column (Employed status) by selecting the first...

The first post referenced:
The employment status depending on the Name would be "Manager", "Fired", "Enjoying Life". I basically need to insert 3 different columns into a single column.
Then you wrote:

Well it's still not clear to me. Here are examples of both. If you're choosing concat then make sure table_b has wide enough column to fit (including the spaces).
August 15, 2019 at 10:34 pm
Do you want concatenation or coalescence of the 3 columns? Can be 1 and only 1 value per row in these 3 columns? Could all 3 columns have values in...
