@maropu Thanks. I will update the entries. I got this idea from DB2 which supports this syntax. Here is the sample output for your perusal.
```
db2 => describe select * from desc_tab;
Column Information
Number of columns: 2
SQL type Type length Column name Name length
-------------------- ----------- ------------------------------ -----------
497 INTEGER 4 C1 2
449 VARCHAR 10 C2 2
```
