I'll add this as a caveat. I'm an analyst so my SQL isn't really exposed to anyone other than myself and so I wasn't aware of this, thanks for flagging.
A random person claims adding 1=1 is a security risk and you are going to add it as caveat without verifying if the claim is true nor knowing why? That's how misinformation spreads around.
OP doesn't know what they are talking about because adding 1=1 is not a security risk. 1=1 is related to sql injections where a malicious attacker injects 'OR 1=1' into the end of the where clause to disable the where clause completely. OP probably saw '1=1' and threw that into the comment.
Duration of working with SQL doesn't matter. The better SQL programmers don't do it specifically, and have experience in real languages that they bring over to database queries.
Not sure I get this. But I think it does matter since you understand why people do it to begin with. I worked on two enterprise solutions over the last couple of years that have this exact problem. That people are using WHERE 1=1 and then add random "AND something=something" that completely trashes the performance of the db. Also, it does not matter as much on-prem. But in cloud envs it does. Since you can't really spike CPU and mem the same way as on-prem.
The reason I pointed out this specific issue is just that I thought it was the worsed of many poor tips. ChatGPT can give better tips.
Jesus. The problem is not WHERE 1=1. It is WHY people do it. People do it because they then in Python, JS or whatever can easily add conditions. Like QUERY + "AND x='blabla'". There is the problem. Every time you create a unique SQL statement the query will need a new query plan in most SQL engines. Some will cache parts of the query. And you could use parameters along with this paradigm but if you are this bad at SQL I doubt it.
It is kinda funny that op backpedal on this cause to me the whole site is amateurish. I just pointed out what I thought was the worst part. It is likely that it is generated by AI. Either way the post is terrible.
I'm an analyst so I literally only query for analytical purposes. I don't have any SQL code embedded in an application so the 1=1 is purely for tweaking/testing a query more quickly.
I certainly didn't use AI, all these tips/tricks are from work experience and reading Snowflake documentation and the like, but I guess I can't convince you either way. Regardless I appreciate the feedback!
