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.
For the above expression, my conversion will be
ROUND( ((CCol4 / DECODE (CCol1, 0, NULL, CCol1) )), 0).
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.
Ex:
[Col4 + Col2]/[Col3-Col1]*[Col5].

I have created a procedure using the Dynamic SqL and while using the NVL() getting the following error . ORA-00936: missing expression.
The query I have written as
SQL_Txt:=' INSERT INTO VF.tblCData (A, B, C, D, E, F,G,H,I,J)
SELECT '||l_A||',
'||l_B||',
'||l_C||',
'||l_D||',
NULL ,
'||L_F||',
[code]....
For Param1 I have data for one execution and Param2 and Param3 is null for that execution.While executing the same I am getting below
INSERT INTO VF.tblCData (A, B, C, D, E, F,G,H,I,J)
SELECT 25,
1,
7,
6,
NULL ,
5,
[code]....
and error ORA-00936: missing expression is popping up for Param2 and Param3 NVL(,'')

I have 2 tables used in this problem: ODETAILS and ORDERS.
ODETAILS has the following columns: ONO, PNO, QTY, COST
ORDERS has the following columns: ONO, CNO, ENO, RECEIVED, SHIPPED, ORDER_COST
UPDATE ORDERS
SET ORDER_COST= 1 * ( select SUM(
SELECT COST
FROM ODETAILS
WHERE ORDERS.PNO=ODETAILS.PNO
)
);
In ODETAILS there can be more than 1 row for 1 order. So I'm trying to add all the COSTs in ODETAILS.

I have a very simple table with 2 columsn. As_of_date is one of the column. This column is "Date" data type.
When I use distinct clause inside a to_char function it gives the following error:
ORA-00936: missing expression
00936. 00000 - "missing expression"
The Sql is
select to_char(distinct(as_of_date),'mm-dd-yyyy') from sales
I can't see any syntax error in the sql..but forsome reason, it doesn't work.

I have 3 tables.
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.

I have a complex expression coming as an input and I have to break that into smaller one to evaluate each of them. Explained in example:
Let's assume, I have an input string as "(({A}&{B})||({C}||{D})&({E}||({F}&{G})))". My requirement is to break into logical smaller groups like
1. ({F}&{G})
2. ({E}||({F}&{G}))
3. ({C}||{D})
4. (({A}&{B})

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
so that only those lines will be returned.
