Function To Take In Expression And Fetch The Result
Jun 5, 2009
I have an arithmatic expression which is dynamic say
expression = [Col5]/[Col1]
I will be using this in building a dynamic SQL.so i have to make sure that the divisible by zero is taken care. In the expression Col1,Col5 are values coming from a SQL.
I have to build a function which takes in the expression and fetches me the result.My expression can be any combination of arithmaticexpression involving columns.
Table 1 have 3 columns ID, CUS_NAME, LOC insert into table1 values (001,ABC,North); insert into table1 values (002,DEF,South); insert into table1 values (003,GHI,West);
Table 2 have 3 columns ID, CUS_NAME, LOC insert into table2 values (001,ABC,North); insert into table1 values (002,DEF,East); insert into table1 values (003,JKL,South);
Table 3 is Result_Tab table having 8 columns ID, TAB1_CUS_NAME, TAB2_CUS_NAME, Cus_Name_Res, TAB1_CUS_LOC, TAB2_CUS_LOC, Cus_LOC_Res, Comment.
I have written two cursors which fetches data from both the tables and compares each data between each other and inserts the value into the result table.
the code is as follow:
Insert into Result_Tab values (T1.ID, T1.Cus_Name, T2.Cus_Name, decode(T1.Cus_Name,T2.Cus_Name,'Y','N'),T1.LOC, T2.LOC, decode(T1.LOC,T2.LOC,'Y','N'),Null);
Now I want the resul as follows: ID T1.N T2.N N_Res T1.L T2.L L_Res Comment 001 ABC ABC Y North North Y Null 002 DEF DEF Y South East N Loc 003 GHI JKL N West South N Name, Loc
Is there a way wherein i could capture the column names in decode function when it doesn't match, so that I can insert the same in the comment column.

My master-detail form has single canvas. For both blocks, master and detail, two tables joined together in each. One table to be updated, second table has some info for reference (query only).
I am getting these errors when in detail block the item from LOV is selected for existing record. This does not happen for new record inserted in detail block.
when i am running the below plsql block i am getting the error like not a group by expressiong.

How can I do this parentObject.getChildObject().setChildFunction()?
im trying to take a query that pulls all the info in the current tables, and narrow it down to one day plus current. here is the error i am getting.

I wrote a query for minimum average salary of Job_id using inline view but it is not working..
The query is as follow
SELECT job_id, avg(salary) FROM employees , (SELECT MIN(AVG(salary)) min_avg_sal FROM employees GROUP BY job_id) b GROUP BY job_id having avg(salary)=b.min_avg_sal;
It returns error as
################################ having avg(salary)=b.min_avg_sal * ERROR at line 6: ORA-00979: not a GROUP BY expression #########################
New to using Oracle and SQL Developer. I am trying to subtract a maximum date from today and adding back 1 to get a field named daysSinceLastActivity....
Syntax I am trying is (date()-max(activity_date))+1 as daysSinceLastActivity
I keep getting a error message of missing expression. After googling, I am not finding anything. This should be a simple calculation.
I have a user interface where the user can enter a formula using a set of parameters and operators. For eg , the user is given a list of parameters, say : Width, Height , Gauge. The list of operators include standard math functions : + - / * ^
He can select and create a formula like gauge * width. This is stored in a table. At a later time a job is scheduled to evaluate the formula based on parameters for width, gauge and height.
I can evaluate the expression by substituting each parameter.
I can do this using dynamic sql. However I'm not sure how to evaluate the ^ symbol. The equivalent of this is power function.
So if a user enters (height * 2) + (width^2) . How do i evaluate this. I am doing this in pl/sql.
I am using pipelined functions. I've written a few with no problem this one seems to be giving an error when I am using techniques that appear very similar to ones that work.
I am doing this all in a package;
The type definition is;
TYPE SUSPECT_LINKAGES_FAC_RECORD IS RECORD ( PATIENT_ID TUMOR.TUMOR_PATIENT_ID%TYPE, CENTRAL_SEQ TUMOR.TUMOR_CENTRAL_SEQ%TYPE, MP_REVIEW_FLAG NUMBER(1), FACILITY_FLAG NUMBER );
The variable definition is;
OUT_REC SUSPECT_LINKAGES_FAC_RECORD;
The line with the error is;
PIPE ROW(OUT_REC);
This is the entire function;
FUNCTION GET_SUSPECT_LINKAGE_FAC_FLAGS RETURN SUSPECT_LINKAGES_TABLE PIPELINED AS CURSOR CURS_SUSPECT_LINKAGES IS SELECT * FROM TABLE(TUMOR_UTILITIES.GET_SUSPECT_LINKAGE_FLAGS()) order by 1,2,3 DESC; TEMP_REC SUSPECT_LINKAGES_RECORD; MATCH_COUNT NUMBER; OUT_REC SUSPECT_LINKAGES_FAC_RECORD;
[code].....
I get "PL-00382 expression is of wrong type" on both pipe row (out_rec); lines.
I ran into a problem recently which has to do with the following query:
SELECT '' || ROUND(GEOGR_LAENGE,5) || ',' || ROUND(GEOGR_BREITE,5) || '," [BUE] ' || BAUFORM_GRUPPE || '"', KM AS TEXT FROM MYTABLEA mmtable WHERE (mmtable.GEOGR_LAENGE IS NOT NULL AND mmtable.GEOGR_BREITE IS NOT NULL AND mmtable.STRECKE_NR IN (
[code].....
The problem is, that Oracle alerts a missing expression at line 4, and highlights the "IS NOT NULL". Personally I don't see that anything is wrong with this line. I think the problems source is somewhere else but I cannot find it.
I'll give you a little bit of background to the script:
What I am trying to achieve is to request the values in the first line with the following conditions:
- mmtable.GEOGR_LAENGE, GEOGR_BREITE must not be empty - rbtable.STRECKE_NR for the requested line (which is similar to mmtable.STRECKE_NR) must have "MITTE" as a value for NL_NAME - mmtable.KM => rbtable.VON_KM - mmtable.KM <= rbtable.BIS_KM
