If you’re getting an error that reads “ERR syntax error” in Redis, it could be because you’re calling the SPOP command with too many arguments.
At the time of writing, I find that I only get this argument when I pass too many arguments. If I pass no arguments, I get a different error.

At the time of writing, I find that I only get this argument when I pass no arguments. If I pass too many, I get a different error.
In any case, to fix this issue, be sure to pass at least one argument to the command (and at the time of writing, no more than two).

If this is the case, you can easily fix the issue by making sure that the first argument reflects the actual number of sets that you’re comparing.
Continue readingIf you’re getting an error that reads “ERR Number of keys can’t be greater than number of args” when using the SINTERCARD command, it’s probably because your first argument is the wrong value.
To fix this issue, make sure the first argument reflects the number of sets that you’re comparing.

Continue readingIn SQL Server, if you’re getting error Msg 4127 that reads “At least one of the arguments to COALESCE must be an expression that is not the NULL constant”, it’s probably because all of your arguments to the COALESCE() expression are the NULL constant.
To fix this issue, make sure at least one argument is not the NULL constant.

Continue readingIf you’re getting error message “Msg 206” that reads “Operand type clash: date is incompatible with int” in SQL Server while trying to add to (or subtract from) a date, it’s probably because you’re trying to perform arithmetic between an integer and a date value.
To fix this issue, either change the date value to a datetime value or use the DATEADD() function.
