Description

Aggregate function.

The MAX() function calculates the maximum value across a group of values.

Syntax

  1. > MIN(expr)

Arguments

ArgumentsDescription
exprAny expression

Returned Value

Returns the minimum value of expr. MIN() may take a string argument, in such cases, it returns the minimum string value.

Examples

  1. > drop table if exists tbl1,tbl2;
  2. > create table tbl1 (col_1a tinyint, col_1b smallint, col_1c int, col_1d bigint, col_1e char(10) not null);
  3. > insert into tbl1 values (0,1,1,7,"a");
  4. > insert into tbl1 values (0,1,2,8,"b");
  5. > insert into tbl1 values (0,1,3,9,"c");
  6. > insert into tbl1 values (0,1,4,10,"D");
  7. > insert into tbl1 values (0,1,5,11,"a");
  8. > insert into tbl1 values (0,1,6,12,"c");
  10. > select min(col_1d) from tbl1;
  11. +-------------+
  12. | min(col_1d) |
  13. +-------------+
  14. |           7 |
  15. +-------------+
  17. > select min(col_1c) as m1 from tbl1 where col_1d<12 group by col_1e;
  18. +------+
  19. | m1   |
  20. +------+
  21. |    1 |
  22. |    2 |
  23. |    3 |
  24. |    4 |
  25. +------+

Constraints

Currently, MatrixOne doesn’t support select function() without from tables.
