If you get an error that reads “WRONGTYPE Operation against a key holding the wrong kind of value” when using the ZINTER command in Redis, it’s probably because you’re passing a key with the wrong data type.
To fix this issue, be sure that each key you pass to the ZINTER command is either a set or a sorted set.
If you’re getting an error that reads “ERR wrong number of arguments for ‘smismember’ command” in Redis, it’s because you’re calling the SMISMEMBER command with the wrong number of arguments.
To fix this issue, make sure you’re passing the correct number of arguments. This command accepts two or more arguments, which represents a key and one or more members to check against that key.

In other words, the NEXT VALUE FOR function does not support the PARTITION BY sub clause of the OVER clause.
To fix this issue, either remove the PARTITION BY clause or change the statement to use another method for partitioning the results.
If you get an error that reads “WRONGTYPE Operation against a key holding the wrong kind of value” when using the ZUNION or ZUNIONSTORE commands in Redis, it’s because you’re passing a key with the wrong data type.
To fix this issue, make sure the keys you pass to these commands contain either sets or sorted sets. Although these commands are for sorted sets, they also work with non-sorted sets.
Continue readingIf you get an error that reads “WRONGTYPE Operation against a key holding the wrong kind of value” when using the LRANGE command, it’s probably because you’re passing a key with the wrong data type.
To fix this issue, be sure that the key you pass to the LRANGE command holds a list.
If you’re getting an error that reads something like “ERROR 1050 (42S01): Table ‘customers’ already exists” when trying to create a table in MySQL, it’s probably because there’s already a table in the database with the same name.
To fix this issue, either change the name of the table you’re trying to create, or check the existing table to see if it’s the one you actually need.
Continue readingIf you’re getting an error that reads “ERR value is not an integer or out of range” when using the HRANDFIELD command in Redis, it could be because you’re passing a second argument that isn’t an integer. Or if it is an integer, it could be out of range.
If you’re getting an error that reads “ERR wrong number of arguments for ‘srem’ command” in Redis, it’s probably because you’re calling the SREM command with the wrong number of arguments.
To fix this issue, make sure you pass the correct number of arguments. At the time of writing, the SREM command requires at least two arguments.
If you’re getting an error that reads something like “The requested range for sequence object ‘Sequence1’ exceeds the maximum or minimum limit. Retry with a smaller range.” in SQL Server, it’s probably because you’re trying to return a value that’s outside the range of the sequence object.
This can happen when you’re using the sp_sequence_get_range stored procedure to return a range from a sequence object that exceeds the minimum or maximum value for that sequence object, and the sequence object does not have CYCLE defined. It’s a similar error to error 11728, which can happen when using NEXT VALUE FOR to generate a new value from a sequence.
If you’re getting an error that reads something like “The sequence object ‘…’ has reached its minimum or maximum value. Restart the sequence object to allow new values to be generated.“, it’s probably because you’re using a sequence that’s reached the minimum or maximum value specified in its definition.
