Here is some SQL cipher to acknowledge the highest-performing salespeople at AdventureWorks and advertisement their managers.

It produces the afterward result…

So, the cipher works, but it is ugly. If I charge to accept and advance the code, I’ll aboriginal charge to get it into a clear form.

I accept SQL Prompt, so I can hit Ctrl K -Ctrl Y (mnemonic ‘Kick Yourself’), it applies its absence congenital cipher appearance and that fixes that. Well, no it doesn’t, because I’m assured that you still don’t like the way it is formatted. No two developers can anytime accede about how cipher should be formatted.

After haughtily abnegation all the added congenital styles, (SQL Prompt | Active Style…), you adjudge to actualize your own.

Once you accept created your own style, you can adhere assimilate it. If you attending in the band at the top of the Formatting Styles window (SQL Prompt | Active Appearance | Adapt Appearance or SQL Prompt | Adapt Formatting styles), you can see area they are currently stored (%LOCALAPPDATA%Red GateSQL Prompt 9StylesV2).

You can see that the cipher styles are XML files with a accomplished deluge of settings:

sql - Is this database in third normal form/10NF? - Stack Overflow - sql normal forms
sql – Is this database in third normal form/10NF? – Stack Overflow – sql normal forms | sql normal forms

You can abundance your styles anywhere that can be accomplished by the filesystem, so you can allotment your adopted appearance with your colleagues, authoritative it easier and quicker for them to disagree with it.

You can save the styles in Antecedent Control, which is abnormally advantageous if you’re advantageous abundant to accede on a “common style” for the team. Of course, you can still administer your own adopted appearance back you charge to assignment on code, afresh reapply the aggregation appearance aloof afore committing your changes.

I advance that you adapt your adopted appearance occasionally, because the Prompt Aggregation is actively accretion the cardinal of options and putting in corrections, and you can get a nice abruptness back SQL Prompt aback gets afterpiece to your preferences. I wouldn’t admonish you to adapt the XML directly, though, because the SQL Prompt appearance editor is so cute. It additionally lets you see the aftereffect of all your adjustments on the accepted query.

I like to get as aing as accessible to the styles acclimated by Itzik Ben-Gan in his books, which is additionally aing to what Joe Celko uses in his archetypal books. I will altercate with anyone that SQL was consistently advised to be as aing to absolute accounting accent as possible. It was advised so anyone could accept it. Its phrases, clauses, and punctuation should be as aing as accessible to what you see in literature. It is a abundant aberration to advance it beyond the folio like a table with aberrant alignments, or commas bottomward the larboard margin.

If you are disturbing adjoin these sorts of agnosticism in the accumulated cipher style, afresh artlessly use ‘kick yourself’ (Ctrl K-Ctrl Y) to get it to the apprehensible appearance you like best, and afresh reapply the accumulated appearance aloof afore you save it to antecedent control

You actualize a new appearance from the Formatting Styles window, and its abject will be an absolute style. Call it what you will, but I’ve called “Better” and based it on congenital Collapsed style, aloof because it doesn’t do abundant formatting, so there is beneath to undo.

This launches you into the Prompt appearance editor, and you charge to assignment out how to adapt all the administration options, and actions, to get as aing as accessible to your adopted layout.

One cogent change I accomplish is to accredit wrapping, and set “the wrap” to 78 characters, back I broadcast a lot of cipher online. I afresh go through and accomplish abiding the assorted clauses, expressions and variables band up as I like, on the new line, back wrapping occurs.

I won’t airing through every detail of all the added appearance options I tweak, but for every option, I artlessly ask myself ” What would Celko or Itzik choose?”. I’ve provided my custom ‘better’ appearance as a download, and you can attending through the assorted settings, and adapt them as required. You could additionally analysis out Louis Davidson’s custom style, in case that’s afterpiece to your adopted style.

As you try out altered settings you should analysis the appulse of anniversary change, either on the sample cipher that Prompt provides, or on your own query. The sample cipher is acceptable to appearance you the abounding appulse of your appearance choices, but with your own query, you can absolutely see how it deals with your requirements. All you charge to do is by analysis the Preview accepted concern box at the bottom.

As you go through the assorted options, you will agitate your arch in admiration that anyone would ambition to appearance their cipher in that way, but every advantage you see has been requested at some point, some of them by me.

If you can’t acquisition the advantage that you need, there is a chase advantage that allows you to acquisition it. While Prompt provides several options for putting assorted clauses and announcement assimilate new curve if the band exceeds the wrap, I capital one that dealt with the AS byword for a acquired table, like the SalesPerformance one in our example. With the chase option, I was able to affirm that there is an advantage for putting the AS on a new band in CTEs, but not one for acquired tables. I bet it will be there soon!

With a few account of effort, I was there. You’ll see that I got about SQL Prompt’s admiration to accomplish a best band than the wrap, for the acquired table, by putting in an inline animadversion followed by a carrying return, at the point area I capital the band break.

If you’re developing new code, it’s best to get the cipher formatted as you want, afore abacus all the inline comments adapted to explain what it’s declared to do. Inline comments can bind things a bit for Prompt, so it is sometimes bigger to do it afterwards the cipher is analytic able-bodied laid out.

If SQL Prompt can’t cope with a area of code, alike with the advice of your new custom style, afresh you can artlessly highlight the curve you don’t appetite Prompt to format, and use the “Action list” to baddest the Attenuate formatting for called argument action.

All this does is bury two inline comments about the called text, so you can additionally do it aloof by abacus these comments manually:

Many SQL Prompt users will accept cipher that has these comments about it, cogent Prompt not to attack formatting it. This is about because Prompt can accomplish a blend of it. Currently, for example, it can do actual aberrant things to Extended Events CREATEEVENTSESSION code). You charge to analysis that occasionally by removing the comments and aggravating again, because the developers for SQL Prompt absorb a lot of time abbreviation those quirks.

Occasionally, I acquisition it advantageous to be able to unformat the SQL cipher entirely, by highlighting the cipher and allotment the Unformat action. This will disengage the furnishings of all blueprint options (those that affect whitespace only).

It will aish all band breaks, except area there are inline comments, as contrarily the inline attribute (–) will animadversion out the code.

However, unformat will not disengage the furnishings of any accomplishments you’ve activated that change the argument of the code.

Most of the options that are allotment of a Prompt cipher appearance affect whitespace only, and there is additionally a set of case options for keywords, congenital functions and so on. The options that alone affect whitespace are classified as blueprint options. Back you hit Architecture SQL (‘kick yourself’) SQL Prompt applies the blueprint options authentic by your custom style, by default, by active the Administer blueprint (format SQL) action.

It will also, by default, automatically run the Administer case options, Accept semicolons and Prefix N to Unicode accurate cord capricious assignments actions:

These actions, and others, will change your code, i.e. they adapt the argument of the queries. Prompt will go added in this administration should you wish, acceptance us to accredit the afterward accomplishments to additionally run as allotment of Architecture SQL:

You can’t about-face out of any accomplishments that change the text, application Unformat, so Ctrl-Z is your best acquaintance here. However, this is a hardly bound accomplishment because you additionally charge about-face aggregate done back you fabricated the absurd accommodation to add aboveboard brackets everywhere. Thankfully, there is usually an activity that is adverse to it, such as Aish Aboveboard Brackets and its angry accompanying Add brackets to all identifiers.

You ability anticipate that best of these accomplishments are harmless, and they about are, but they can be irritating. If you decide, for example, to architecture code, automatically acceptance Prompt to Accept semicolons, while you are still developing it actively, afresh you will either accept to booty them out afresh back you add a article or bethink to accept the article afore the semicolon. If article irritates you like this, afresh attenuate this activity and run it manually back you’ve finished.

Having the Expand Wildcards activity run automatically sounds useful, but sometimes, as back application OpenJSON with a WITH article to accommodate absolute schema, the wildcard is added adapted than a continued bombastic account of columns that ability eventually belie the absolute activity if you adapt it.

Qualifying article names aloof accomplish no faculty if there is alone one table source. It aloof makes plain, simple cipher longer.

In short, I advance that some of these accomplishments should alone be performed alone to the layout. This is actual accessible to adjust. You aloof use Prompt’s Options chat to baddest the accomplishments that you don’t appetite performed as allotment of Architecture SQL:

You will see that I don’t run Expand wildcards or Qualify article names as allotment of Architecture SQL, because I adopt to do that alone from the layout. I’ve called to accumulate the Accept semicolons activity active by absence because, admitting casual annoyances, I so about balloon to do it later. For the others, I can aloof run these accomplishments individually, as required, from the capital Prompt card or from the Activity list, or application a keyboard shortcut.

Remember that Prompt Options are activated universally, behindhand of what custom appearance you are using. If at any point you charge to displace these options to their defaults, you can hit Restore all defaults in the basal larboard of the Prompt Options awning or backslide aloof one set of options (such as Suggestions > Join conditions) to their defaults application the top appropriate Restore defaults one.

The blueprint options of SQL Prompt accept consistently been handy. They came to SQL Prompt back two Redgate tools, SQL Prompt, and SQL Refactor, were combined. Afterwards that, it lay agilely until it was absolutely revised to adaptation 2. This revised blueprint apparatus was so abundant better, in that it could actor the blueprint styles acclimated in appear and edited SQL code. This aback answer blueprint into one of the above affidavit for application SQL Prompt.

The actual actuality that there is so abundant altercation about the actual blueprint for SQL Server makes it an abnormally difficult to accommodate a apparatus that accommodates all tastes. SQL Prompt has, by adamant incremental improvements over several years, succeeded able-bodied with this.

There was a time back grey-muzzled SQL Developers had their own routines to architecture code. It was fun. It alone had to architecture the cipher the way we capital it formatted, and it acclimatized abilities in recursive coast and added parsing techniques that one best up in college. With SQL Prompt, all this is unnecessary. It now does blueprint able-bodied abundant for about all requirements. I charge now accept that I use it for best of the accessories I write.
