OR is not supported with CASE Statement in SQL Server
...
That format requires you to use either:
CASE ebv.db_no
WHEN 22978 THEN 'WECS 9500'
WHEN 23218 THEN 'WECS 9500'
WHEN 23219 THEN 'WECS 9500'
ELSE 'WECS 9520'
END as wecs_system
Otherwise, use:
CASE
WHEN ebv.db_no IN (22978, 23218, 23219) THEN 'WECS 9500'
ELSE 'WECS 9520'...
Break promise chain and call a function based on the step in the chain where it is broken (rejected)
...ink it does.
Let's say you have something like the following:
stepOne()
.then(stepTwo, handleErrorOne)
.then(stepThree, handleErrorTwo)
.then(null, handleErrorThree);
To better understand what's happening, let's pretend this is synchronous code with try/catch blocks:
try {
try {
try...
Angular HttpPromise: difference between `success`/`error` methods and `then`'s arguments
...and leave it to OP to edit.
The major difference between the 2 is that .then() call returns a promise (resolved with a value returned from a callback) while .success() is more traditional way of registering callbacks and doesn't return a promise.
Promise-based callbacks (.then()) make it easy to...
Aren't promises just callbacks?
...ay that resembles synchronous code and is much more easy to follow:
api().then(function(result){
return api2();
}).then(function(result2){
return api3();
}).then(function(result3){
// do work
});
Certainly, not much less code, but much more readable.
But this is not the end. Let's ...

What does the function then() mean in JavaScript?

});
In this example, we first fetch the server configuration. Then based on that, we fetch
information about the current user, and then finally get the list of items for the current
user. Each xhrGET call takes a callback function that is executed when the server
responds.
Now of cours...
Resolve promises one after another (i.e. in sequence)?
...p = Promise.resolve(); // Q() in q
files.forEach(file =>
p = p.then(() => readFile(file));
);
return p;
};
Or more compactly, with reduce:
var readFiles = function(files) {
return files.reduce((p, file) => {
return p.then(() => readFile(file));
}, Promise.resolv...
How can I generate an INSERT script for an existing SQL Server table that includes all stored rows?
...r existing data. This is a stored procedure which you need to run once and then it is tailor made for you.
I tried to find this kind of stuff for a while but wasn't satisfied with the results, so I wrote this stored procedure.
Example:
