| Summary | 0002880: MySQL code assumes only one database name is ever used | ||||||||
| Description |
Say you have two MySQL servers at 1.2.3.4 and 1.2.3.5. Each one has a few databases (catalogs), no overlap in database names. <?php $conn = mysql_connect('1.2.3.4', 'myuser', 'mypass'); mysql_select_db('some_db', $conn); $conn2 = mysql_connect('1.2.3.5', 'myuser', 'mypass'); The above code will successfully connect to the 1.2.3.4 server and switch to the some_db database. But then the second mysql_connect() will fail with an "Unknown database 'some_db'" exception because the MySQL code is caching the last selected database name and sticking it on the end of the JDBC URL it uses to connect to the second database. |

My hacky patch which probably breaks something else but at least makes the problem stop happening is to just comment out the line of code that records the database name: --- a/modules/quercus/src/com/caucho/quercus/lib/db/Mysqli.java +++ b/modules/quercus/src/com/caucho/quercus/lib/db/Mysqli.java @@ -922,7 +922,7 @@ public class Mysqli extends JdbcConnectionResource { try { if (isConnected()) { String catalog = dbname.toString(); - getEnv().getQuercus().setSpecial("mysql.catalog", catalog); + //getEnv().getQuercus().setSpecial("mysql.catalog", catalog); validateConnection().setCatalog(catalog); |
