<p>Hi,</p> <p>I&#39;ve just started a project where I write a lot of SQL queries. Currently I write them as a multiline string variable. Is there a way to store them in proper SQL files (so I can enjoy color syntax and other good things :) ) and generate these string variables at the build time ? Thank you in advance</p> <p>Edit : I don&#39;t want to use an ORM as I use advanced PostGis queries and want to limit dependencies.</p> <p><strong>EDIT2 :</strong> Thank you all for the answer, go generate seems the way to go (ah ah), I&#39;ll try it !</p> <hr/>**评论:**<br/><br/>dinkumator: <pre><p>You could try <code>go generate</code> with something like this: <a href="https://github.com/jteeuwen/go-bindata" rel="nofollow">https://github.com/jteeuwen/go-bindata</a> (bonus is that debug mode accesses files directly)</p></pre>bietekwiet: <pre><p>i use this often and it works flawlessly.</p></pre>TheMerovius: <pre><p>Not at build time, go intentionally doesn&#39;t support build-time processing. But <a href="https://blog.golang.org/generate" rel="nofollow">go generate</a> is usually used for this kind of stuff. Just write it into an sql file and then write a short go program (hedged by a <code>build +ignore</code> or something) that generates a .go file from then. Then add a <code>go:generate</code> comment somewhere that <code>go run</code>s that program and run <code>go generate</code> before/at each commit.</p> <p>I don&#39;t know if there are ready-made solutions to this. Another way would be to use a pre-existing solution for statically compile in files from source and then write code to read from disk/that statically compiled in FS at runtime to find the queries.</p></pre>bear1728: <pre><p>You could use go generate to embed the contents of some sql files into your program before compiling. There was post about them here:</p> <p><a href="https://mattjibson.com/blog/2014/11/19/esc-embedding-static-assets/" rel="nofollow">https://mattjibson.com/blog/2014/11/19/esc-embedding-static-assets/</a></p> <p>I also wrote a <em>very</em> simple version here:</p> <p><a href="https://github.com/tscholl2/embd" rel="nofollow">https://github.com/tscholl2/embd</a></p> <p>Most of these won&#39;t deal with multiple queries in the same file, but you may be able to figure something our for that.</p></pre>flexd: <pre><p><a href="https://github.com/nleof/goyesql" rel="nofollow">https://github.com/nleof/goyesql</a></p> <p><code>nleof/goyesql</code> does exactly what you want!</p></pre>
