# convert calls to xx_ SQL to Pear::DB |
| 4 |
|
| 5 |
# this is ugly cludge. Since MySQL calls xx_connect and expects to |
| 6 |
# see database connection and after that calls xx_select_db to select |
| 7 |
# which database to use, we ignore that alltogether. Insted, we are using |
| 8 |
# well-known global variables to make correct connection to database, and |
| 9 |
# ignore xx_select_db. |
| 10 |
# |
| 11 |
# That *WILL* break some aplication - it should LibData also, since it uses |
| 12 |
# three databases. However, LibData is using SQL syntax with dots in it, |
| 13 |
# so behaviour can be emulated (at SQL level) using PostgreSQL schema |
