ora-00904

I have a table called calendars. One of its columns is named 'date' When I want to select the date column it gives error ORA-01747 namely invalid table.column. select date from calendars I guess this happens because 'date' is a reserved word for pl/sql. The problem is it's not even possible to change the column name : alter table calendars rename column date to date_d Result is: ORA-00904 error: invalid identifier. What do you advice? Thanks. FrustratedWithFormsDesigner Have you tried select calendars.date from calendars; /* or you could alias "calendars" if you don't want to type so much */

I see an error while executing hibernate sql query. java.sql.SQLException: ORA-00904: "table_name"."column_name": invalid identifier When I open up the table in sqldeveloper, the column is present. The error is only happening in PROD, not in DEV. What should I check? It could be a case-sensitivity issue. Normally tables and columns are not case sensitive, but they will be if you use quotation marks. For example: create table bad_design("goodLuckSelectingThisColumn" number); Oracle will throw ORA-00904 if executing user does not have proper permissions on objects involved in the query. This

I'd like to get in one query a post and the first comment associated with the post. Here is how I do it in PostgreSQL: SELECT p.post_id, (select * from (select comment_body from comments where post_id = p.post_id order by created_date asc) where rownum=1 ) the_first_comment FROM posts p and it works fine. However, in Oracle I'm getting an error ORA-00904 p.post_id: invalid identifier. It seems to work fine for one subselect, but I cannot get the comment with only one due to the fact that I need to use rownum (no limit / offset in Oracle). What am I doing wrong here? No, Oracle doesn't

I have this procedure: PROCEDURE P_LOAD_EXPIRED_ACCOUNT ( pDayDiff IN NUMBER, ExpiredCur OUT MEGAGREEN_CUR ) IS BEGIN OPEN ExpiredCur FOR SELECT ACCOUNT_NAME, SERVICE_TYPE, CASE WHEN SERVICE_TYPE = 1 THEN ADD_MONTHS(ACTIVATED_DATE,3) WHEN SERVICE_TYPE = 2 THEN ADD_MONTHS(ACTIVATED_DATE,6) WHEN SERVICE_TYPE = 3 THEN ADD_MONTHS(ACTIVATED_DATE,12) END AS EXPIRED_DATE FROM SUBSCRIBERS WHERE (EXPIRED_DATE - CURRENT_DATE) < pDayDiff; END; but SQL Developer generate this error: Error(20,10): PL/SQL: ORA-00904: "EXPIRED_DATE": invalid identifier I believe that PLSQL allows me to use Alias in Where

I have installed Oracle 10g in my virtual XP and created a table using create table reg1 ( fname varchar2(30), lname varchar2(30), addr varchar2(30), mail varchar2(30), occu varchar2(30), uname varchar2(30), passwd varchar2(30) ); and the table created successfully.But when I am trying to fetch the values by simple query like select fname, lname from reg1 where uname="bbb"; I am getting error like ORA-00904: "bbb": invalid identifier I cannot understand what I have done wrong here. Use single quotes. select fname,lname from reg1 where uname='bbb'; Oracle uses double quotes " in order to
