oracle10g

问题 I writing an application using Oracle 10g. I am currently facing this problem. I take in "filename" as parameter of type varchar2. A sample value that filename may contain is: 'TEST || to_char(sysdate, 'DDD')'. In the procedure, I want to get the value of this file name as in TEST147. When i write: select filename into ffilename from dual; I get the value ffilename = TEST || to_char(sysdate, 'DDD') whick makes sense. But how can I get around this issue and invoke the function in the string

问题 Is there a way to get metadata for the Oracle built-in aggeregate and other functions such as AVG, STDDEV, SQRT, etc.? I need to know object id and arguments meta. In the SYS.ALL_OBJECTS view I couldn't find anything useful. I also tried to search in SYS.ALL_ARGUMENTS view by object_name. Is there views or tables with built-in functions with data similar to SYS.ALL_OBJECTS and SYS.ALL_ARGUMENTS ? 回答1: You have tagged Oracle 10g, but from what I can find, you'll need Oracle 11g r1 to find out

问题 I am trying to implement a sequence in an Oracle database to act as a surrogate key creator for a table. For performance reasons, I want this sequence to be cached. I have read that there are potential pitfalls when using cached sequences since rollbacks and instance failures will result in missed values. This got me to thinking. Let's say I create a sequence with a cache size of 100. Then I make a 50 record insert to my table, with the sequence value as the primary surrogate key. After the

问题 I'm looking for a script which disables all the jobs. Right now I highlight them all in Toad, click the take offline button and then commit changes. There has to be a way to do this in PL/SQL. 回答1: If you want to prevent all jobs from running, you can change the initialization parameter JOB_QUEUE_PROCESSES . If you set that to 0, Oracle won't run any jobs scheduled using DBMS_JOB . You could also mark the jobs broken BEGIN FOR x IN (SELECT * FROM user_jobs) LOOP dbms_job.broken( x.job, true )
