Returns x rounded to integer by dropping digits after decimal point. Returns the signum function of x, that is:įor double arguments, the function additionally returns:
Returns x rounded to the nearest integer. radians ( x ) → double #Ĭonverts angle x in degrees to radians. Returns the modulus (remainder) of n divided by m. Returns x rounded down to the nearest integer. Returns Euler’s number raised to the power of x. degrees ( x ) → double #Ĭonverts angle x in radians to degrees. Returns x rounded up to the nearest integer. Splits string by entryDelimiter and keyValueDelimiter and returns a map.Mathematical functions and operators # Mathematical operators #ĭivision (integer division performs truncation) Split_to_map( string, entryDelimiter, keyValueDelimiter ) Splits string on delimiter and returns the field index Splits string on delimiter and returns an array of size at most limit Splits string on delimiter and returns an array Right pads string to size characters with padstring Returns string with the characters in reverse order Replaces all instances of search with replace in string Removes all instances of search from string Returns the starting position of the first instance of substring in string Transforms string with the specified normalization form Transforms string with NFC normalization form Left pads string to size characters with padstring Returns the Levenshtein edit distance of string1 and string2 This function returns the length of string in Athena Returns the concatenation of string1, string2, …, stringNĭecodes a UTF-8 encoded string from binary
DATEDIFF ATHENA AWS CODE
Returns the Unicode code point of the only character of string
Returns the Unicode code point n as a single character string The table below lists string functions, and the Athena SQL syntax for it. Since Athena is based on Presto, Athena String functions are a one-to-one match between the two. Similar to string functions in a database, you can use Athena String functions to manipulate data stored as character strings. Returns the sample variance of all input values Returns the population variance of all input values Returns the sample standard deviation of all input values Returns the population standard deviation of all input values Returns linear regression slope of input values. Returns linear regression intercept of input values. Numeric_histogram( buckets, value, weight )Ĭomputes an approximate histogram with up to buckets number of buckets for all values with a per-item weight of weight Each key can be associated with multiple valuesĬomputes an approximate histogram with up to buckets number of buckets for all values Returns a multimap created from the input key / value pairs. Returns n values of x associated with the n smallest of all input values of y in ascending order of y Returns the value of x associated with the minimum value of y over all input values Returns n smallest values of all input values of x Returns the minimum value of all input values Returns n values of x associated with the n largest of all input values of y in descending order of y Returns the value of x associated with the maximum value of y over all input values Returns n largest values of all input values of x Returns the maximum value of all input values Returns a map created from the input key / value pairs Returns the excess kurtosis of all input values Returns a map containing the count of the number of times each input value occurs Returns the geometric mean of all input values Returns the sample covariance of input values Returns the population covariance of input values Returns the number of non-null input values Returns correlation coefficient of input values Returns an order-insensitive checksum of the given values Returns TRUE if any input value is TRUE, otherwise FALSE Returns TRUE if every input value is TRUE, otherwise FALSE Returns the bitwise OR of all input values in 2’s complement representation Returns the bitwise AND of all input values in 2’s complement representation Returns the average (arithmetic mean) of all input values Returns an array created from the input x elements Returns the approximate weighed percentile for all input values of x using the per-item weight w at each of the given percentages specified in the array Returns the approximate weighed percentile for all input values of x using the per-item weight w at the percentage p, with a maximum rank error of accuracy Returns the approximate weighed percentile for all input values of x using the per-item weight w at the percentage pĪpprox_percentile( x, w, percentage, accuracy ) Returns the approximate percentile for all input values of x at each of the specified percentages Returns the approximate percentile for all input values of x at the given percentage Returns the approximate number of distinct input values with a standard error less than e Returns the approximate number of distinct input values
