| 189 | 1 """sqlpyPlus - extra features (inspired by Oracle SQL*Plus) for Luca Canali's sqlpython.py |
| 2 | |
| 3 Features include: | |
| 4 - SQL*Plus-style bind variables | |
| 5 - `set autobind on` stores single-line result sets in bind variables automatically | |
| 6 - SQL buffer with list, run, ed, get, etc.; unlike SQL*Plus, buffer stores session's full history | |
| 7 - @script.sql loads and runs (like SQL*Plus) | |
| 8 - ! runs operating-system command | |
| 9 - show and set to control sqlpython parameters | |
| 10 - SQL*Plus-style describe, spool | |
| 11 - write sends query result directly to file | |
| 12 - comments shows table and column comments | |
| 13 - compare ... to ... graphically compares results of two queries | |
| 14 - commands are case-insensitive | |
| 15 - context-sensitive tab-completion for table names, column names, etc. | |
| 16 | |
| 17 Use 'help' within sqlpython for details. | |
| 18 | |
| 19 Set bind variables the hard (SQL*Plus) way | |
| 20 exec :b = 3 | |
| 21 or with a python-like shorthand | |
| 22 :b = 3 | |
