问题 I have a database which stores usernames only in English at the moment. I would like to incorporate BASE64 & UTF-8 in order to store in other languages as well; I want to store it in a column of type NVARCHAR2 . The database procedure receives the name in BASE64 , I'm decoding it via UTL_ENCODE.BASE64_DECODE & converting the string to VARCHAR2 using UTL_RAW.CAST_TO_VARCHAR2 . But I get gibberish back and not the actual word. For example I get 'алекс' as the name in BASE64 . I'm able to decode

问题 I'm trying to write an INSERT INTO that does a some DISTINCT/GROUP BY work. The query runs perfectly fine as a select statement, but will not work if it's wrapped into an INSERT INTO. INSERT INTO MasterRecords (BatchRecordRecordID, SourceID, BatchID) SELECT RecordID, SourceID, BatchID FROM ( SELECT RecordID, BatchID, 101 AS SourceID FROM BatchRecords WHERE BatchID = 150 GROUP BY RecordID, BatchID ) BR This earns me: SQL Error: ORA-00979: not a GROUP BY expression But if I remove just the

问题 Creating a new database (basic and advanced), It's my first time dealing with Oracle, in which I do not know why so many tables, triggers, views and other objects when only wanted to create a relational data base empty. Is there another way to do this or is there something I missed understand? Thank you. Capture: 回答1: Those objects are owned by SYS user.

The no increments with year : | no | year | +----+------+ | 1 | 2016 | | 2 | 2016 | | 3 | 2016 | | 1 | 2017 | | 2 | 2017 | | 4 | 2016 | For now I have created sequence for each year but the problem is Oracle will not automatically create new sequence in next year. Another problem is if I want to use a 3D sequence, incrementing within year and type : | no | year | type | +----+------+------+ | 1 | 2016 | a | | 2 | 2016 | a | | 1 | 2016 | b | | 1 | 2017 |

问题 I am looking for a solution to create the SQL INSERT statements using PL/SQL script for the select statement result set. Looking for similar feature available in the SQL Developer tool (export --> format insert) but I want the solution as script rather than using any tool(s). I have referred the below solution. However, I would like to know whether any better way to do it as the solution is old and not very simple. EXPORT AS INSERT STATEMENTS: But in SQL Plus the line overrides 2500

问题 I try to create an auto incremented column on a table and as I see in this post there are 2 ways, the second implementation with the Identity column is a more elegant solution, but when I try to implement it I get the following error: Error at Command Line : 3 Column : 31 Error report - SQL Error: ORA-02000: missing ALWAYS keyword 02000. 00000 - "missing %s keyword" Actual table script implementation: CREATE TABLE "PLATFORM"."AUTH_PERMISSION" ( ID NUMBER(19,0) GENERATED BY DEFAULT ON NULL AS
