SQL & PL/SQL :: Function To Check Length And Build A String?
Dec 18, 2012
I have created a VIEW with a column containing user-defined aggregated values(stores the output in varchar2 data type). Some of the records exceed the maximum limit, for example varchar2(4000). I was suggested a PL/SQL function to check the length and build a string if necessary..
CREATE OR REPLACE
FUNCTION SUBURL(col1 IN VARCHAR2, col2 IN varchar2)
RETURN varchar2
[Code].....
Here, I got the following error,
Error(4,25): PLS-00103: Encountered the symbol "," when expecting one of the following:
:= . ( @ % ; not null range default character
If i try to find length of the string with more than 4000 char in SQL Developer it throws error "ORA-01704: string literal too long". if anything i need to SET in preference.
select length('string with more than 4000 char) from dual;
I want to read content from blob column and write into file using dbms_output.put_line. See below code. i am getting PLS-00215: String length constraints must be in range (1 .. 32767) error.
set serveroutput on DECLARE l_file UTL_FILE.FILE_TYPE;
[Code]....
the length of the blob column is 1081656. so i have changed in raw(1081656) in above code. after the execution, i am getting the below error PLS-00215: String length constraints must be in range (1 .. 32767).
notes column having 2000 characters max, i want my string output based on 35 characters, ya i need to replace tag after 30 characters in the string.. I need out put as "hi hello how are you doing out there, similar i need to calculate the sting length and have to split it 35+35+35..
This i tried
select substr(note,1,(instr(note, ' ',35)))||' '||substr(note,instr(note, ' ',35),(instr(note, ' ',35)))notes from test
Where I am copying the data from one database to another I am getting this error.
ORA-01458: invalid length inside variable character string
This is applicable for only character string.

i m create one function in which i have to concatenate result likeDate is 19/07/2010'. i tried to concatenate in select statement. in this case function is created successfully but it gives error when it run.
CREATE or replace function TEST(FINYEAR VARCHAR2) RETURN VARCHAR2 AS QRY_STRING VARCHAR2(1000); BALANCE VARCHAR2(100);

ERROR at line 1: ORA-00923: FROM keyword not found where expected ORA-06512: at "TEST", line 11
Years ago, someone created a database in Oracle that was carried over and now sits in Oracle 10g. I am developing an application that queries this database and returns the result as XML.
Many (thousands) of rows have an item description that contains an ampersand. I want each of these pieces of data to have it written as & amp; (had to add a space so it would show up here, but you know what I mean) instead of &, but I don't feel like doing thousands of UPDATEs to change this.
Does Oracle have any global find/replace functions that I can call? I'd rather do one update statement that replaces all occurances of & with & amp; but I can't seem to find a function that will do this.
I'm thinking something that would work like:
UPDATE table SET column1=REPLACE(column1,oldstr,newstr);
I have a package includes 22 functions, each function just returns a sql template (clob type).
I also have a stored procedure called query_builder, query_builder has applicationName and statementName as parameters. I need to call these functions in the package based on the given applicationname and statementname.
CREATE OR REPLACE PROCEDURE Query_builder (ApplicationName varchar2, StatementName varchar2) IS SQLSkeleton varchar2; BEGIN PackageName := ApplicationName||'_SKELETON; SQLSkeleton := PackageName.StatementName; -- I know this will not work, but how can i call these function dynamically?
I'm trying to find a simple way of getting around this. I have a PL/SQL procedure which loops through a list of values in a table. These values are the actual names of the functions I want it to run in sequence. The problem is I can get the string value each time but I need to store the return value of each function into a number variable e.g.
BEGIN open all_tests; fetch all_tests BULK COLLECT INTO test_tabl; close all_tests;
for myindex IN 1..test_tabl.count LOOP
time_taken := test_source1 ==> this will work but how do I avoid hardcoding the name of the function to be executed and use the test_name value instead?? time_taken is declared as a number (ie the return value of each function is a number)
test_detail := test_tabl(myindex).test_name; ==> test_detail now contains the string name of the function dbms_output.put_line('Test detail is ' || test_detail); end loop;
I have created a function that is used for splitting a comma separated string & give the output in tabular form.here is the function
Here I have used CLOB as my input string will be huge(greater than max limit of varchar2)
CREATE OR REPLACE TYPE SPLIT_TBL_CLOB AS TABLE OF CLOB; CREATE OR REPLACE FUNCTION CSVTOSTRING_CLOB ( P_LIST CLOB, P_DEL VARCHAR2 := ',' ) RETURN SPLIT_TBL_CLOB PIPELINED
[code]....
But here I am facing 2 problems.
1. The function is not accepting a large string & I am getting the error
I need to remove the alpha characters from a string, leaving only numbers, but I am getting unexpected results:
SQL> SELECT TRANSLATE('3N', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', NULL) a FROM DUAL; A -
I thought this would leave the 3 from the 3N, but it is returning an empty string. For my application, the string '3N' could be any length, will only contain letters and numbers, and the letters will always come at the end, but there could be more than one letter
How can i write a query so that i takes the average of students in each room and display the output? I need to write a query so that it also picks up any new rooms and students added. Average is sum of total students in room by number of times each room is specified.
eg: A1 is listed 3 times a the result would be 10+20+15 divided by 3.
I installed oracle11g on my computer ,when im going to build demo its not working.its giving a error like this.
sys>conn u1/u1 error accesing PRODUCT_USER_PROFILE warning product user profile information not loaded you may need to run PUPBLD.SQL AS SYSTEM connected u1>@?/sqlplus/demo/demobld unable to open file "/oraeng/app/oracle/product/11.1.0/sqlplus/demo/demobld.sql"
We have developed a code which builds a trigger on a atble dynamically at run time usinf Dynamic SQL command Execute immediate.
create or replace PROCEDURE GENERATE_TRIGGER ( P_TNAME IN VARCHAR2
[Code].....
I am not usre if the error is due to insufficient privileges as we are able to build tabl;e in the system dynamically using the above mentioned command.
I am an absolute neophyte at this. I'm fairly good at SQL, but have not administrated a database before.
I am trying to take a backup from our production database and restore it to a fresh install of Oracle 10.2 on a Windows 2003 server using RMAN - but I am not getting very far. Software versions are all the same. I have access to the manuals, but it seems like every link I follow adds more questions than it answers.
I have gone through the wizard and set up oracle on the new box - that all seemed to go smoothly. In order for this to work, do I need to set up the database with the same DBID as the one in the backup files? Or is there a way to import the data from the backup and have it build the database from those files?
I'm not sure I'm even asking the right questions. Do any of y'all know of a tutorial that would walk me through this process step by step?
We have an requirement to create xml data for entire database (selected tables) which are in hierarchy.Procedure should read node_mapping table having parent and child tables relationship info and build XML Select statement.
Currently it is building SQL statement whenthere are one parent having multiple childrens i.e Dept having emp, emp_act, emp_rsch..but when child node are having childrens then it is not working - it has to repeatedly call this procedure (recursive) and build below given SQL statement.
1. To change procedure to build xml sql statement when there are multiple childrens to child nodes (hierarchy) 2. To format the output in xml data
We have an requirement to build (XML) Select statement dynamically based on the mapping table (which is in hierarchy format)
I have removed xml keyword, so query will not work. but need procedure which will recursively check mapping table (parent and child table) and build below given select statement.
I want to build a hierarchy and output it into a sub-report. Since the data in few hierarchy fields exceeds 4000 characters and therefore m getting the ORA-01489 error and the entire report was failing.
So i have used user aggregate function to print the out put. I have also used row_number() to print sequence in query output.
ID Causality -- ------ 3755101 )Blisters (Blister) Causality as per report1: Probable Causality as per report2: Possible Dechallenge : Not Applicable Rechallenge : Not Applicable 2 )Mental status changes (Mental status changes) [code].......
but the expected out put is
ID Causality -- ------ 3755101 )Blisters (Blister) Causality as per report1: Probable Causality as per report2: Possible Dechallenge : Not Applicable Rechallenge : Not Applicable [code]........
but it should be as
1) 2) 3) .. .. .. 10) 11) 12) for the values in the causality field
I have built a Menu Framework using the following instructions.

I am facing 2 problems.
1. If the user is in a child application and clicks logout. He is taken to the login screen of the master application (Correct), but once he enters login details, he is returned to the child application (False). I think he should be returned to the Home page of the Master application.
2. If I set Session Timeouts in the Edit Security Attributes of the applications. Then if the user is timed out, he is sent to the login screen of the Master application (Correct). If he then logs in, he is sent the the Home page of the Master application (Correct).
Now if he clicks a link to a child application he is then sent back to the Master application login screen. He then has to login again. He is sent to the Master Home page and everything is then ok.
