问题 Does anyone know how do I connect to MongoDB via SQL Developer? I Have tried to install the third Party JDBC Drivers in SQL Developer for MongoDB but after restarting the SQL Developer I cannot see any options available. Thanks in advance, Vassilis 回答1: Sorry, MongoDB is not a supported migration platform, so we do not support connections to it. We offer connections to 3rd party databases to allow for migrations to Oracle Database. It's not designed to be a poly-DBMS IDE/GUI. 来源： https:/

问题 I want this query to loop, but add this question after getting the results, "Would you like to search for another column?" ACCEPT column_name CHAR PROMPT 'Please insert column name' SELECT DISTINCT owner, table_name FROM all_tab_columns WHERE column_name IN ('&column_name'); If the user types in 'no' program ends with "Have a nice day". If user types in 'yes', the program starts over again requesting the user to input another column name. I know it's simple. I mainly work in SQL Server, but

问题 I have recently taken data dumps from an Oracle database. Many of them are large in size(~5GB). I am trying to insert the dumped data into another Oracle database by executing the following SQL in SQL Developer @C:\path\to\table_dump1.sql; @C:\path\to\table_dump2.sql; @C:\path\to\table_dump3.sql; : but it is taking a long time like more than a day to complete even a single SQL file. Is there any better way to get this done faster? 回答1: SQL*Loader is my favorite way to bulk load large data

问题 I have an oracle database where the dates are recorded as 8 digit number as for example: 59696580 which represent '01/07/2013 00:00:00' 59696610 which represent '01/07/2013 00:30:00' Would someone know how to convert this 8 digit number into a date in Oracle SQL? Thanks 回答1: It might depend on the timezone, but looks like this number is the number of minutes since 12-30-1899 1:00:00 , given the dates you want them to represent. In order to get the date, you can just use the addition +

问题 I'm trying to work around the SQLDeveloper linesize bug by writing my script to detect whether it's SQL*Plus or SQLDeveloper. Something like: COLUMN SET_THE_LINE new_value TARGETLINESIZE noprint SELECT DECODE ('&&_SQLPLUS_RELEASE.','',5,500) as SET_THE_LINE from dual; SET LINESIZE &&TARGETLINESIZE I know that SQL*Plus always sets the value of _SQLPLUS_RELEASE and, understandably, SQLDeveloper does not. Unfortunately SQLDeveloper always prompts for the value of _SQLPLUS_RELEASE. Any

问题 I need to Generate an export script of entire Oracle Database using using SQL Developer. How can I do this? 回答1: Tools-> Database Export? 回答2: For backing up the entire database, I'd recommend using expdp/impdp from the command line. If you only need the objects and not the data, you can use the METADATA_ONLY setting, see http://download.oracle.com/docs/cd/B19306_01/server.102/b14215/dp_export.htm If you really need to generate a SQL script for your complete database and don't want to use a
