What is min in Postgres?
Introduction to PostgreSQL MIN function PostgreSQL MIN() function an aggregate function that returns the minimum value in a set of values. To find the minimum value in a column of a table, you pass the name of the column to the MIN() function. The data type of the column can be number, string, or any comparable type.
How do you find the min of a column?
To find the minimum value of a column, use the MIN() aggregate function; it takes the name of the column or expression to find the minimum value. In our example, the subquery returns the minimum value in the temperature column (subquery: SELECT MIN(temperature) FROM weather ).
What is the purpose of SELECT query?

What is min formula in Excel?

When to use min in a SELECT statement?
No, MIN is used in a SELECT statement that scans more than one line. It takes a column as an argument, and returns the “lowest” value (again, according to the collation sequence) found in that column. Used without a GROUP BY clause, the result set will have a single row, and the value of MIN will be the lowest value found in that column.
How to select minimum value of multiple columns?
This formula can be used to get the minimum value of multiple columns but its really messy past 2, min (i,j,k) would be min (i,min (j,k)) If you’re able to make a stored procedure, it could take an array of values, and you could just call that. However, this could be slower than the other choice.
How to use min and Max in SQL?
