Use this MySQL function to compare two or more values and return the smallest value.
Below is the syntax for this command. Text within square brackets (i.e, [ and ] ) are optional. Choices are separated by bars (i.e, | ). Ellipses preceded by a comma indicates a repeating pattern. Ellipses before or after syntax are used to highlight a relevant except from the larger syntax. Text displayed in italic letters represent text that should be replaced with the specific names related to the database (e.g., column with the name of the column).
LEAST(value, value, . . . )
Use this function to compare two or more values and return the smallest value. In an INTEGER datatype context, all values are treated as integers for comparison. In a REAL data type context, all values are treated as REAL values for comparison. If any parameter contains a case-sensitive string (i.e., with a BINARY keyword), all values are compared as case-sensitive strings.
SELECT LEAST(col1, col2, col3);
