SQL & PL/SQL :: Get MAX Length Of Column Value Along With Field Value
Oct 4, 2012
create table test_schema(
col1 varchar2(50)
)
insert all
into test_schema values ('this_is_a_test')
into test_schema values ('this_is_a_test_test')
into test_schema values ('this_is_a_test_test_xxxx')
into test_schema values ('this_is_a_test_test_aaaaaaaa')
select * from dual;
I want to get the length of the col1 value with maximum length of characters also with that field value.
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 have a problem to read in data from dmp file to target table.
I've created a dmp file using:
CREATE TABLE table_name ORGANIZATION EXTERNAL (TYPE oracle_datapump DEFAULT DIRECTORY directory_name LOCATION ('file_name.dmp') ) AS SELECT col1, col2, col3 from source_table;
[Code]...
The file created via db_link from target db to remote db and then the data are insterted into target db table target_table.
desc target_table col1 varchar2(20) col2 number col3 number
There are no values longer than 20 characters in source table, but when I insert into target_table(col1, col2, col3) as select col1, col2 col3 from source_table; I get ORA-12899: value too large for column "target_table"."col1" (actual: 25, maximum: 20).
I gues it has something to do with how the oracle datapump stored the data in dmp file. When I select col1 from source_table where length(col1) > 20; I get two values which clearly are not longer than 20 characters.
Selected values are:
748473358 693197674
where the bug is hidden or any "normal" workaround?
I need to insert these two records into below tables(NGF_REC_LINK,MDU_19).I got below mentioned result while trying to execute my ctl file (ngf_test.ctl )
For 1st record : I am getting beloe error
Record 1: Rejected - Error on table NGF_REC_LINK, column TABLENAME.Field in data file exceeds maximum length
For 2nd record : Because inputs filed is missing in file,Data is miss arranged into table like
I am struggling with a simple data load using sqlldr
Ref: I am running Oracle 11.2 on Linux 5.7. =========================== Here is my table: SQL> desc ntwkrep.CARD Name Null? Type
[code]...
Looking at the actual data and counting the characters for the "REALIZES" column data, I see that it is roughly slightly over 1000 characters.
So, attempting various ideas to fix the problem, I tried changing nls_length_semantics to "char" and recreating the table, but this still didn't work and still got the same data load errors on the same rows.
Then, I changed nls_length_semantics back to byte and recreated the table again.This time, I altered the table manually as: SQL> ALTER TABLE ntwkrep.CARD MODIFY (REALIZES VARCHAR2(4000 char));
Table altered.
SQL> desc ntwkrep.card Name Null? Type ----------------------------------------------------------------- -------- -------------------------------------------- CIM_DESCRIPTION VARCHAR2(255) CIM_NAME NOT NULL VARCHAR2(255) COMPOSEDOF VARCHAR2(4000)
[code]...
Here is a copy of the first row of data which fails to load every time no matter how I change the "REALIZES" column in the table.
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit ProductionPL/SQL Release 11.2.0.3.0 - ProductionCORE 11.2.0.3.0 ProductionTNS for Solaris: Version 11.2.0.3.0 - ProductionNLSRTL Version 11.2.0.3.0 - Production I'm trying to load a table, small in size (110 rows, 6 columns). One of the columns, called NOTES is erroring when I run the load. It is saying that the column size exceeds max limit. As you can see here, the table column is set to 4000 Bytes)
CREATE TABLE NRIS.NRN_REPORT_NOTES ( NOTES_CN VARCHAR2(40 BYTE) DEFAULT sys_guid() NOT NULL, REPORT_GROUP VARCHAR2(100 BYTE) NOT NULL, AREACODE VARCHAR2(50 BYTE) NOT NULL, ROUND NUMBER(3) NOT NULL, NOTES VARCHAR2(4000 BYTE),
I want to find the max length for a column in oracle, without querying each of the columns. Are these stats stored somewhere?
I have several fields defined as varchar2(4000). Not all of them use up 4000. Instead of querying each one ..max(column name) i want to explore if there is a way, i can find the max size stored somewhere? dba_tab_cols provides size of the field. is there any table that provides max used so far?
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 want to add a column data of datatype number of all the tables at a time in a database..
i am trying with the all_tab_columns but i can get only the column info whether it is number or varchar2 or any other data type but i am unable to retrieve the column name and the sum of length of the data present in all the rows in that column...
We have some tables in our database in which for loading data we have the setup in place to do Exchange partition after data load into staging. Today we did changes to column length to one pair of main and staging table. Post that Exchange partition stop working.
I have one issue while loading the value through sql*loader the last column data is SG1 and when its loaded , it is length of this columns is showing 4 char. Unable to understand, how to find this extra space. Though used TRIM but does not work.
How the length of column width effects index performance?
For example if i had IOT table emp_iot with columns: (id number, job varchar2(20), time date, plan number)
Table key consist of(id, job, time)
Column JOB has fixed list of distinct values ('ANALYST', 'NIGHT_WORKED', etc...).
What performance increase i could expect if in column "job" i would store not names but concrete numbers identifying job names. For e.g. i would store "1" instead 'ANALYST' and "2" instead 'NIGHT_WORKED'.
I am currently working on a bug that came from a user. An oracle form is used for entering employee information and the backend table is employees. One for the field here is LAN ID. It was found that some users were using space bar either before or after entering the Lan id and this is causing issues in finding the employees in the system. A request is being submitted to not let any blanks or space to be entered in the field. In the table, this particular field/column datatype is varchar2 and the size is 8.
How do I make no blanks or spaces to be entered in the field or otherwise, even if they put a space or blank, the field should only use the actual ID entered.. Is it possible?
I've started using Apex 4.2(new to Apex). I have built a form based on a table with a date column on it. The form allows update on all fields/columns of the base table. For the date field/column, the goal is to present the user with sysdate on load and update the date with sysdate if the record is changed any of the fields. How can I accomplish this?
I was looking for application column name corresponding to "Draft Invoice Number" ra_interface_lines_all table.
I tried the below.
/* Get descriptive_flexfield_name for the application table name*/ SELECT * FROM FND_DESCRIPTIVE_FLEXS_VL WHERE application_id = 222 AND APPLICATION_TABLE_NAME=upper('ra_interface_lines_all');
/* Get the application column name and end user column name*/ SELECT * FROM FND_DESCR_FLEX_COLUMN_USAGES WHERE application_id = 222 AND descriptive_flexfield_name = 'RA_INTERFACE_LINES';
There are many DESCRIPTIVE_FLEX_CONTEXT_CODEs obtained. I could finally trace out that draft invoice number corresponds to INTERFACE_LINE_ATTRIBUTE2. How can I know what DESCRIPTIVE_FLEX_CONTEXT_CODE should I look for?
I want to build a single query to fetch the application column name and flex field name for a specific table .
I have a table where i need to update one field values based on another field of the same table , simply as it is.I have done this using one select all check box , on clicking that all check boxes of item_trans table will get selected , then i will un select some of check box and then using one button, i will update the value of the fields which are checked only.
I have put the sample code but when i am updating its taking long time and hanging.I am also attaching the form based on the test case provided.
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE1',40,NULL); insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE2',20,NULL); insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE3',20,NULL);
--i want to set the value of trans_Act_qty as trans_qty
--i create one dummy or test block to keep the select all check box. for that table test script is
CREATE TABLE TEST ( C VARCHAR2(2000 BYTE), B NUMBER, A NUMBER );
insert into test (C,B,A) values ('A',1,1);
--code written in select all check box which is created on test.block.
BEGIN GO_BLOCK('item_trans'); FIRST_RECORD; LOOP :M_END_YN := :M_END_ALL; [code].......
--code written in M_END_YN ( actual check boxes where i will uncheck).
IF :M_END_YN = 'N' THEN :M_END_ALL := 'N'; END IF;
--code written on button to update those values which are checked.
BEGIN GO_BLOCK('item_trans'); FIRST_RECORD; LOOP IF :M_END_YN = 'Y' THEN [code]......
