What is the difference between != and Operator in SQL Server as both of them works same for Not Equal To Operator?
Very interesting question indeed. Even though this looks very simple when I asked quite a few people if they know the answer before I decided to blog about it. The answer which I received was that it seems that many know the answer but everybody wanted to know the more about it.
Here is the answer – Technically there is no difference between != and . Both of them work the same way and there is absolutely no difference in terms of performance or result.
Here is the follow up question I received right I answer that there is no difference between those operator.
If != and both are the same, which one should be used in SQL queries?
Here is the answer – You can use either != or both in your queries as both technically same but I prefer to use as that is SQL-92 standard.
Though, many of the leading database applications supports both of the operators. For example –
- SQL Server
- IBM Informix
Here is my return question to you which one of the following operators you use for NOT EQUAL TO operation?
