Can you add a disclaimer? Count operations can be slow and expensive.

[dplewis]

Looks good, I’ll add this to the PHP SDK as well.

Thanks for contributing, just a couple minor suggestions.

[dplewis]

I thought it was true by default? You can just use query.withCount() no?

[BufferUnderflower]

If you want to know the total number of rows in a table satisfying your query, for e.g. pagination purposes - you can use withCount() (optionally accepts a boolean, defaults to true when called without arguments or undefined).

Will this be more clear?

[dplewis]

(optionally accepts a boolean, defaults to true) should be fine

[BufferUnderflower]

can't this be mis-interpreted like it's an always enabled by default on every query?

[dplewis]

@TomWFox What do you think?

[TomWFox]

I agree with @dplewis, it's referencing that particular method not querying in general

[TomWFox]

Alternatively, you could not mention the optional boolean as its not strictly relevant to this explanation.

[BufferUnderflower]

right, jsdoc will show these details anyway when it comes to coding

[TomWFox]

@dplewis are you happy with that change?

[dplewis]

Thanks for contributing! I added this to the PHP SDK too.

@dplewis Seems styling for markdown quotes is a bit too much

[dplewis]

Nice catch! I can take a look at it.
