i have 10 records in sql table . the records contains data as gender with male and female. please reply me with a query that can change male into female and female into male with a single query.
Now that Lynn has thoughtfully provided a correct solution to your question, let me ask you: What happens if you run Lynn's query and one of the rows contains the value of "Other" in the gender column?
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
