In SQL Server, the BIT_COUNT() function returns the number of bits set to 1 in the given argument, based on the binary equivalent of that argument.
Different values will have a different number of 1s in their binary value. Also, the same value can have a different number of 1s, depending on the data type.
Continue readingSQL Server 2022 introduced the SET_BIT() function that sets a bit in an integer or binary value (other than a large object).
The function allows us to specify an offset for which to set a bit to 1 or 0.
In SQL Server, RIGHT_SHIFT() is a bit manipulation function that returns the first argument bit-shifted right by the number of bits specified in the second argument.
The RIGHT_SHIFT() function was introduced in SQL Server 2022.
In SQL Server, LEFT_SHIFT() is a bit manipulation function that returns the first argument bit-shifted left by the number of bits specified in the second argument.
The LEFT_SHIFT() function was introduced in SQL Server 2022.
SQL Server 2022 introduced the GREATEST() function that returns the maximum value from a list of values. You may be thinking, “but there’s already a MAX() function that returns the maximum value, so why the need for another function that does the same thing?”.
Well here’s the thing – they don’t do the same thing. They’re actually quite different functions, used in different scenarios.
If you’re wondering what the difference is between the MAX() and GREATEST() functions, read on to find out.
If you’re using SQL Server’s GENERATE_SERIES() function/relational operator and you’re getting an empty result set, then it could be due to one of the following reasons.
From SQL Server 2022 we can use the JSON_PATH_EXISTS() function to test whether a specified SQL/JSON path exists in the input JSON string.
It’s similar to the JSON_CONTAINS_PATH() function that’s available in MySQL and MariaDB.
In SQL Server, we can use the JSON_ARRAY() function to construct JSON array text from zero or more expressions.
The resulting array contains the values we provide as arguments. Providing zero expressions results in an empty array.
Continue readingIn SQL Server, we can use the JSON_OBJECT() function to construct JSON object text from zero or more expressions.
The resulting object contains the key/value pairs that we provide as arguments. Providing zero expressions results in an empty object.
Continue readingIf you’re using the GENERATE_SERIES() function to create a series of numbers, but you’re finding that only the first value in the series is returned, it could be something very obvious.
The obvious reason this could happen is that your step value is too big. In particular, if the step is so big that it covers the whole series, then it stands to reason that there will only be one value in the series.
If this is an issue for you, you might want to check that you’re using an appropriate step value. Using a smaller step value can help to create a series with more values.
