I have just downloaded and installed SQL developer version 1.2 from Oracle.OTN .
Immediately noticeable improvement are the new GUI, the support for two additional RDBMS's like MySQL and SQL Server and also the improved data export capability. In my opinion, the support offered by the previous version was not working correctly since it offered on DML statements for creating the tables you might have wanted to copy or move to an other database using SQL.
I had one small problem though. It seems to me that sql developer is checking the values of the JAVA_HOME and JDK_HOME variables in order to determine the JDK to use. openSUSE defaults these to the /usr/lib/jvm/java path which contains a 1.4.2 jdk, so the workaround was to modify sqldeveloper.sh file so it looks like this :
#!/bin/bash export JAVA_HOME=/home/thanassis/java/jdk1.5.0_12 export JDK_HOME=/home/thanassis/java/jdk1.5.0_12 cd "`dirname $0`"/sqldeveloper/bin && bash sqldeveloper $*
