SQL & PL/SQL :: Insertion Of Text Content Length Contains More Than 4000 Into CLOB?
May 31, 2011
i want to insert the text lenght containing more than 4000 characters, that column datatype is in CLOB Even though in CLOB we can able to store upto 4GB. Its not allowing me to insert more than 4000 characters at a time , but we can able to insert by splitting the data by 4000 and can append remaining characters But i am receving the text contains more than 4000, that how can i split the data upto 4000
I've to create a table which has 650 fields and the total length of CREATE TABLE statement got to be more than 4000 characters.I've to create the table by inserting the CREATE TABLE statment in a variable (V1) then by using EXECUTE IMMEDIATE V1 Since VARCHAR2 only supports upto 4000 characters length string, how can I create such table??
DECLARE V1 VARCHAR2(4000); BEGIN V1 := -- CREATE TALBE STATEMENT WITH LENGTH MORE THAN 4000 EXECUTE IMMEDIATE V1; END;
Quote:got the error -- PL/SQL: numeric or value error: character string buffer too small
I want to execute a DML query with execute immediate statement. That DML query length exceeds 4000 characters. This query has Xquery related conditions, i can not split the query. when i tried execute it is giving "string literal too long". I tried with DBMS_SQL.Parse() and DBMS_SQL.Execute also, but it is giving same error. I have to execute this DML query inside a Procedure. We are using oracle 10g version
i have another problem with clob column , when i try to insert data in it through the stored procedure then it shows an
error- 'ORA-01460: unimplemented or unreasonable conversion requested clob' and this error especially arise when data to e inserted in clob column , have more than 4000 characters.
sql>exec pi_test(1,'sysdate','text of clob column'); ORA-01460: unimplemented or unreasonable conversion requested clob
I had a varchar2 variable which was storing some data and I could use the LENGTH function to get the length of the data. However, If I change it to CLOB. What is the best way to get the length?
I'm loading data from text file separated by TAB and i got the error below for some lines. Event the column is CLOB data type is there a limitation of the size of a CLOB data type. The error is:
Record 74: Rejected - Error on table _TEMP, column DEST. Field in data file exceeds maximum length
I'm using SQL Loader and the database is oracle 11g r2 on linux Red hat 5. Here are the line causing the error from my data file and my table description for test:
create table TEMP ( CODE VARCHAR2(100), DESC VARCHAR2(500), RATE FLOAT, INCREASE VARCHAR2(20), COUNTRY VARCHAR2(500), DEST CLOB, [code]........
I am only able to extract only 4000 characters from the clob column "DESCRIPTION".how to get more characters or max for that column with the same query concept?
I have extracted data from table and write into one text via sqlplus utility in shell scripts. i got correct output. i am having two issues on the output file
1) Outfile file size is huge high compare then table segment data.
2) last column having extra space.
The output column is clob datatype. so i have added set long 50000 and set longchunksize 50000 parameter. after adding these only i got above issues. without two options, i am not getting this isssue but lines are wrapped.

I am using Oracle Version 11.2. Here's an example of what I am trying to do..
-- create table with a clob column create table sr_test (c1 CLOB)
-- load data that is more than 4000 characters into clob declare var1 varchar2(32000); begin var1:= '';
for i in 1..5000 loop var1:= var1||i||',';
end loop; dbms_output.put_line(var1); insert into sr_test(c1) values (var1); end;
-- select table to make sure clob is loaded
select c1, dbms_lob.getlength(c1) from sr_test
-- create procedure to return data from table
create procedure sr_p1(result out sys_refcursor) is begin open result for select c1 from sr_test; end;
-- run the procedure to get data
DECLARE RESULT sys_refcursor;
BEGIN RESULT := NULL;
ACCOUNTING.SR_P1 ( RESULT );
:rc0_RESULT := RESULT;
END;
Everything works as intended. However, this procedure is being called from Webservices. According to what I have been told, webservices adds 18ms for each clob that needs to be converted into char so it can be displayed on the screen. So, I need something like this
create procedure sr_p1(result out sys_refcursor) is begin open result for select dbms_lob.substr(c1,32000,1) from sr_test; end;
Is there an alternate method to send more than 4000 characters in the refcursor?
I have a insert statement where i need to insert data to a column where i need to insert value more than 4000 char into column.
Different approaches and condition: 1. CLOB should not be used 2. Need full value to be stored
Approach: 1.I created few more dummy columns to insert the data , was inserting 4000 char and if exceeded i was inserting to next column, but this will be tedious if we have 35000 char 2.Insert in the same column as different rows
I have error message when running duplicate : FRM-21011: PL/SQL unhandled exception ORA-06502..I'm trying to hold 4000 characters in a variable like what do below:
if s_str is NULL then s_str := eachcol.column_name||'{{'|| name_in(name_in('system.cursor_block')||'.'||eachcol.column_name)||'{{'; else s_str := s_str||eachcol.column_name||'{{'|| name_in(name_in('system.cursor_block')||'.'||eachcol.column_name)||'{{'; end if;
It's simple variable to hold value but still can't get by large string though.
Users are reporting that are unable to use the NVARCHAR(4000) due to the character set which is set in the database.
Currently NLS_CHARACTERSET is set to AL32UTF8 and NLS_NCHAR_CHARACTERSET from AL16UTF16
They want me to change both the character set to UTF8, so that they can use the NVARCHAR2(4000) datatype in their tables.
As UTF8 is the subset characterset and I did the cs scan and this found characterset can't be modified to UTF8 and there may be the data dictionary corruption.
Is there any other way so that users can use the NVARCHAR(4000) as datatype. And the reason why NVARCHAR2 is required is, users are trying to import the data from other database which is using NVARCHAR(4000) as one of the field.
In current form, i use *pll file to pass Global.<variable name> to the form *.fmb
The problem is that if i copy a string of 4000 characters (which i need to) to Global.<variable name>, it will automatically cut a whole chunk to shorter string (less than 1000).
Is there a better way to that Global.<variable name> can hold 4000 characters?
In my below query example , i have to pass more than 4000-5000 paramter in "a1.num" in below query. what is the best way to handle this, also if I pass more than 2000 paramter , the query takes a long time to execute. How can we solve the performance issue as well how I can pass more parameter.
The issue is slow insertion in particular table(i.e A Table) it means insertion in all other tables(i.e B, C, D tables) in same schema is going properly but only when i am trying to insert in one particular table(i.e A table) in same schema it takes long time to complete insertion. Daily insertion is 6000 rows.
I have check all the details like Tablespace size, Analyzing of table, Analyzing of indexes and all. There is no any error alertlog file.
i have a simple insert statement in oracle form, which is sucessfully run in oracle database(sql). but it is in oracle form trigger: WHEN BUTTON PRESSED as in this format:
Declare cnt number; begin select count(*) into :control.cnt from ol_lcy_ndc where aan=:control.aan and event_id= 'ACL'; if cnt = 0 then insert into ol_lcy_ndc (form_no, aan, regno, event_id, doev, status, edt, ludt, username) values (12345, 255257,10030661,'ACL', SYSDATE, 'DRAFT', SYSDATE, SYSDATE, ' '); else update ol_lcy_ndc set LUDT= to_date('09-09-2009','DD-MM-YYYY') where aan=:control.aan and event_id= 'ACL'; end if; end;
but after giving count in cnt, it is not doing anything like insert or update from oracle form, but both the statements are correctly execute in oracle database. may problem is linked with some properties of property palette, upto my knowledge i checked: insertion allowed--> yes.
In procedure "update_emp", i am updating a row based on p_empno and if it is not present i.e. SQL%ROWCOUNT = 0, then I am inserting that row into emp table.
where as in procedure "update_emp1" , first I am checking whether any row with that p_empno is present or not,if presentthen update the row, else raise an exception to insert the row.
In both procedure, I am doing the same thing, But I am unable to understand which one is good and why
create or replace procedure update_emp( p_empno int) is begin update emp set ename='raj' where empno=p_empno;
I am using oracle form builder 6i and oracle database 10g
1:I have table named 'info' column name 'InfoId'and some other.And another table named 'Handing' with column names HtId, Value1 and value2.
2:I made form that consist of three data blocks, first block takes criteria and second block display record against that criteria from table 'info'.
3:i want checkboxes agianst that display record,and want that when I select some checkboxes against 'InfoId' these selected 'InfoIds'
should save in another table named 'handing' in column 'HtId'.and in same table data in column value1 and value2 will be inserted through textboxes that are in the third datablock of the thae same form .
We are getting the below error frequently from the application while doing insertion/dataloading to a table. The mentioned error is in the Primary key index
Error: 'ORA-01502: index 'INDEX_NAME' or partition of such index is in unusable state'.
I set the value SKIP_UNUSABLE_INDEXES = TRUE using the command 'ALTER SYSTEM SET SKIP_UNUSABLE_INDEXES = TRUE' to avoid this. Again we are getting the same error and Every time Iam rebuilding('alter index INDEX_NAME rebuild') the index and doing the DML Operation.
I need to insert data from one schema table to other schema's table in same database.The thing is columns are not equal.so when I am trying to use insert statement it is throwing error as not enough values. The situation is explained clearly below.The insert stmt is implemented in second schema whose table name is b.
Table created. SQL> ALTER TABLE B ADD 2 CONSTRAINT B_PK1 3 PRIMARY KEY 4 (ID);
Table altered. SQL> create sequence b_seg start with 1;
Sequence created. SQL> insert into b select b_seg.nextval,lexcom.a.* from lexcom.a,dual; insert into b select b_seg.nextval,lexcom.a.* from lexcom.a,dual * ERROR at line 1: ORA-00947: not enough values
So,for table b in ID column sequence needed to be inserted and other columns need to be taken from table a.I can understand the error is because two tables are not having equal columns.So,the insert stmt is throwing error.
I can manually write by taking columns from a and b and write insert stmt as follows,but this is tedious process.
SQL> insert into b(ID,Name,rollno,address)select b_seg.nextval,lexcom.a.Name,lex com.a.rollno,lexcom.a.address from lexcom.a,dual;
3 rows created.
But this is time taking and I had tables which has many columns to be inserted.So is there any other way to solve it and implement insert stmt.
Restrict field after insertion before commit. i mean when user inputs the data in one field and moves to next field.when ever he want to return back on the previous field it can't be edited.before commit;
Would using a blob based schema load noticeably faster than a binary_double based schema?
CODEBlob Scenario:
Load 1 row: 5 columns (1 integer column, 4 blob columns) of size X VERSUS
CODEDouble Scenario:
Load 10,000 rows: 5 columns (1 integer column, 4 binary_double columns) of size X
While the benefit of using the rows approach is obviously the capability to query the values, I'd like quick answer concerning the loading/insertion performance. Associative array binding is used for loading from a .NET client. Also, would the answer also hold true for 200 columns instead of just 5 columns.
how to define user defined exceptions for cases like, ==> when anyone tries to insert string values without using single quotation marks " '...' "? ==> update the column which is not present in table.
how can I define user defined exceptions for such cases?
How to avoid Junk character insertion in oracle table. I have prepared scripts like this Say
customer - info
After insertion the data is inserted like below in production
Customer ¿ info
We are using command prompt for script execution in production environment. I am using PLSQL developer and SQL developer for development. i cannot see junk data in PLSQL developer and latest SQL developer , but its caught in old version of SQL developer. Also in Application also i can able to figure out junk data.
i have requirement like this i don't know abt trigger
create trigger with the below: Tables: TAB1 TAB2 Create a trigger, if any insertion in TAB1 then records should get inserted into TAB2 create a trigger, if any updation in TAB1 then record should get inserted into TAB2 Create a trigger, if any deletion in TAB1 then record should get inserted into TAB2
I am working in form 6i, EBS11i. I have a multi record data block, i am inserting checked records only using below logic.
ON-INSERT Trigger:
if checkbox_checked('block.checkbox') THEN insert_record; end if;
Requirement: Let us say, i have 4 records, i checked 2 records.. inserted them. Now if i want to insert other 2 unchecked records, it's not accepting, is it possible to insert records which are not checked after insertion.
