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) |
