Parsing annotations within comments / Negative matching of strings in regexps

K uses flex for its scanner, and thus for its regular expression language. As a result, you can find documentation on its regular expression language here.

You want a regular expression that expresses that comments can't start with ! or check:, but flex doesn't support negative lookahead or not patterns, so you will have to exhaustively enumerate all the cases of comments that don't start with those sequence of characters. It's a bit tedious, sadly.

For reference, here is a (simplified) regular expression drawn from the syntax of C that represents all pragmas that don't start with STDC. It should give you an idea of how to proceed:

In MySQL, sad to say, pivoting is hard to do for a mess of arbitrarily named columns.

This gets the result you want (dbfiddle on db-fiddle.com, which offers MySQL 8.)

Why typescript complains object's key is undefined even if the previous command sets a value to that key?

let bar: MaybeThereIsAValue = {};
const key = "carpe";
bar[key] = "diem";

const why = bar[key];
// why is string | undefined

ANSWER

Answered 2021-Apr-05 at 02:04

I got why it would get that.

That is because strictNullChecks of tsconfig is set to be true, which default is false,

and const key = 'carpe' is only executed after the TS is compiled into JS, so TS doesn't know which key it is.

strictNullChecks: When type checking, take into account null and undefined.

So if you want to solve that, my two solutions are:

1. set the strictNullChecks of tsconfig to be false

2. Use ! non-null assertion operator

Joining two LEFT JOINS Together

Asked 2021-Mar-02 at 17:38

I am trying to combine these two LEFT JOINS together.

Preview of tables I am working with:

For example/context:

Table Name: [GMC Claims 2019]

PatNo RevCode CPT BilledCharges DRG 5 141 null 500 439 5 636 J1234 276000 101

Table Name: BCBS_DRG_REIMBURS

DRG Code Description DRG Weight ALOS High Trim Effective Date DRG Rate Per Diem High Trim Outlier 42 XXXXX YYYYY 30 54 10/1/2018 $235,121.59 $5,486.17 101 XXXXX YYYYY 24 40 10/1/2018 $146,736.72 $4,279.82 439 XXXX YYYYY 13 23 10/1/2018 $63,124.34 $3,399.00

Table Name: [BCBS DRG CARVE OUT 07012016]

DRG SERVICE PMT (SDA) 101 DRG CARVE OUT 13537 439 DRG CARVE OUT 13537

Desired Output:

DRG DRG Reimbursement Carve Out PMT 439 $63,124.34 13537 101 $146,736.72 13537

The logic is, given the claims table as our main table, find the DRG codes that match (101 & 439 in this case) and return the respective values (so DRG Reimbursement from the BCBS_DRG_REIMBURS table and Carve Out PMT from the [BCBS DRG CARVE OUT 07012016] table.

I get the sense you are conditionally adding a value to the existing DRG rate so I'm expressing this as an adjustment that is typically zero. Either way your problem was mostly syntactical.

firebase php sdk not supported multi filter data

Asked 2020-Nov-02 at 22:03

I am stuck to multi filter data in firebase with php sdk

...

ANSWER

Answered 2020-Nov-02 at 22:03

This is not a limitation of the PHP SDK (or any other Firebase SDK) - Realtime Database queries only support sorting by one dimension. The SDK just saves you from making a request and getting an error or unexpected results.

If you need to sort by multiple dimensions, you either have to do it in your (PHP) code, or create a compound key/field in the database that you can sort by.

You could do the latter for example by introducing a new field in which the value is active_ or inactive_.

Querying by this field in ascending order would give you the active users sorted by email first, followed by the inactive users sorted by email.

Querying by this field in descending order would give you the inactive users sorted by email first, followed by the active users sorted by email.
