Returns the bit length of a string. bit_lengthreturns a 32-bit integer. To use with InfluxDB,cast the return value to 64-bit integer. bit_length(str) Arguments str: String expression to operate on. Can be a constant, column, or function, and any combination of string operators. ...
The function computes the value of start+length-1. -1+3-1 = 1 and is greater than zero, SQL SUBSTRING extracts one character from the start of the input string. The output is s. If the start+length-1 is zero or less than zero, an empty string returns, as shown in the example be...
