I'm trying to debug an oracle forms application. In production, when I load the application I get an error: java.lang.ClassNotFoundException: oracle.forms.engine.Main I'm uncertain as to what is causing this issue. I've been searching forums for a bout half a day now, and it seems like it may have something to do with a java versioning issue. I've included the (slightly modified to protect my company) java console output, and if I'm reading it right, it looks like a certificate needs to be repackaged. But, when I look at the certificate for the site it says that it's verified by verisign. I'm

I have deleted some tables from an Oracle 10g database using the drop command. When I list the tables using select * from cat; I get the following : Are the tables deleted or not? Why do I have these BIN$... things? How can I remove them or the tables once and for all? Thanks! They are entries in the Recycle Bin, created by the deletion of a table. They can be purged if required. http://docs.oracle.com/cd/B28359_01/server.111/b28310/tables011.htm The tables prefixed with BIN$ are tables placed in the recycle bin for easy recovery. You can completely remove them by purging it. Either

I'm supposed to get every departments average wage and only show the department with the highest average wage. I figured out this query, but it doesn't work. Anyone got some ideas? SELECT department, max(avg(wage)) FROM employees GROUP BY department; I get this error: ERROR at line 1: ORA-00937: not a single-group group function Without CTEs you can do: Select Z.Department, Z.AvgWage From ( Select Department, Avg(Wage) AvgWage From Employees Group By Department ) As Z Where AvgWage = ( Select Max(Z1.AvgWage) From ( Select Department, Avg(Wage) AvgWage From Employees Group By Department ) Z1 )

This is a sample table data Fruit Number Apple 1 Apple 2 Apple 3 Kiwi 6 Kiwi 10 I try to concatenate the table column values to get the following Fruit Number Apple 1-2-3 Kiwi 6-10 Is there a way to query this or store procedure? Something like Concatenate over(partition by) , I don't know much about stored procedures. Thanks! OP is on Oracle 10g , and LISTAGG was introduced in 11g Release 2 . Therefore, in Oracle version prior to 11g where LISTAGG is not supported, you could use ROW_NUMBER() and SYS_CONNECT_BY_PATH functions. SELECT fruit, LTRIM(MAX(SYS_CONNECT_BY_PATH(number,',')) KEEP

Oracle 10g DB. I have a table called s_contact . This table has a field called person_uid . This person_uid field is a varchar2 but contains valid numbers for some rows and in-valid numbers for other rows. For instance, one row might have a person_uid of '2-lkjsdf' and another might be 1234567890. I want to return just the rows with valid numbers in person_uid. The SQL I am trying is... select person_uid from s_contact where decode(trim(translate(person_uid, '1234567890', ' ')), null, 'n', 'c') = 'n' The translate replaces all numbers with spaces so that a trim will result in null if the field

I'm doing an audit of a system, which the developers insist is SQL injection proof. This they achieve by stripping out the single-quotes in the login form - but the code behind is not parameterized; it's still using literal SQL like so: username = username.Replace("'", ""); var sql = "select * from user where username = '" + username + "'"; Is this really secure? Is there another way of inserting a single quote, perhaps by using an escape character? The DB in use is Oracle 10g. Have a look at the testing guide here: http://www.owasp.org/index.php/Main_Page That should give you more devious

I currently am working on a project within Crystal Reports that refuses to use the undocumented function WM_CONCAT, which is allowable within Oracle 10g. Here is the WM_CONCAT header information WM_CONCAT(p1 IN VARCHAR2) RETURN VARCHAR2 To use WM_CONCAT I pass it the following: WM_CONCAT(column1); This function seems to accept a column of type varchar2, and returns a comma delimited list of values from the column. I currently have a custom version of this function that works (on my work computer), but it is not optimal and lacks re-usability. Could anyone provide a good, re-usable function
