    DRUH VARCHAR(32) NOT NULL,

terje7601: I wasn't doing anything special, just working on a Maven Java Web project

GUEST: PHP XDebug process on a Magento App

GUEST: Passing a "SELECT *" query on a table with 3 rows, after just starting NetBEans

GUEST: Trying to view data from database services using jdbc::mysql connector. Id doesnt display the error but throw this instead java heap error.

GUEST: I was executing an SQL command, the output says that the command executed successfully but it does'nt display the view panel where there are the results.

GUEST: Further to 255773 and 255794
I can confirm the problem is limited to running queries with "Execute Command"
The same queries run fine from java programs

GUEST: SQL query hangs
