oracle11g

问题 Ok, I have experience in various databases, but not Oracle specifically, so still trying to wrap my head around how it handles things (i.e. the lack of 'Top' drives me mad!) Anyway, here's what we're trying to do... Note: We're using Oracle 11. I understand a new feature was added to Oracle 12 (i.e. FETCH NEXT n ROWS ONLY ) but we can't use that unfortunately. To start, we have an articles table (technically it's a view, but I'm simplifying it here). Here are the relevant fields... ID

问题 Every time that I run my code I obtain one, or two or several rows on a JSON format. I am using Oracle 11g . This is my CODE on SQL Fiddle, you will find all the data there.

问题 I have a column called Create_Date which has data in the format like 19-JUN-18 10.27.00.000000000 PM and data type is TIMESTAMP(6) . I am trying to look at date range like yesterday's date or between two dates in Create_Date without using TO_DATE(TO_CHAR(P.CREATE_DATE_TIME,'dd/mon/yy')) and entering the value as '19-JUN-18' . I want to use Create_Date=SYSDATE-1 OR Create_Date=CURRENT_DATE-1 instead to filter on yesterdays date. Or Use Create_Date>=SYSDATE or Create_Date>=CURRENT_DATE to look

问题 Following is the sql query (oracle) that I use to get the last record of the returning result of the select query. Is this the optimum way? SELECT HAZMAT_PLACARD_NOTATION INTO v_pcn FROM HAZMAT_CLASS_IRF WHERE HAZMAT_CD = p_stcc_cd and ROWID = (SELECT MAX(ROWID) FROM HAZMAT_CLASS_IRF WHERE HAZMAT_CD = p_stcc_cd); Following is an example result set of the select query where HAZMAT_CD = 4920111 But the last row with the HAZMAT_PLAYCARD_NOTATION value SPONTANEOUSLY COMBUSTIBLE should be

问题 I have 4 different tables: table_price_product (contains information related to the products and their price) table_price_list (contains the information related to the price list) prices_per_client (contains the information related to the prices for the different clients given a specific product) clients (contains the information related to the clients) This is my SQL FIDDLE: LINK I got this: CUSTOMER_NUMBER | CUSTOMER_CLASS_CODE| PRICE (null) | A | 29223 (null) | B | 33223 112121 | E | 40340

问题 I have just tried to login to my db via sql developer as system so i can create a new user. It has come with an error that the password has expired. I have googled a bit but cannot see how to reset the system user password. I guess this is a security issue. My problem is how can I log in as system if the password has expired? How can I unexpire the password without logging in as System users. I seem to be stuck here in a loop where I cannot reset the password expiration. 回答1: Open up cmd.exe

问题 Is there any way to update part of a user-defined type in Oracle? Example: create or replace TYPE MY_TYPE AS OBJECT ( VAR_1 NUMBER, VAR_2 DATE, VAR_3 NUMBER, VAR_4 DATE ); Sample Table: create TABLE TEST_TABLE ( TBL_ID NUMBER, MY_DATA MY_TYPE ); Is there any way to do something like the following: UPDATE TEST_TABLE SET MY_DATA.VAR_3 = 1; Thanks! 回答1: Yes but for some reason you need to alias the table: UPDATE TEST_TABLE T SET T.MY_DATA.VAR_3 = 1; 来源： https://stackoverflow.com/questions
