SQL & PL/SQL :: Multipurpose Varchar2 Column Error When Converting To Date
Aug 16, 2011
i have a varchar2 column containing string values that can be converted to date i.e. ('31-JUL-11') and that column also contains text strings in it. i.e. ('Some string data...')
records whose column value can be converted to date are extractable via where clause (i.e. those rows are associated with some fix number / flag)
now when i try to use to_date function i get the error that
" ORA-01858 a non-numeric character was found where a numeric was expected "
in sql i have added a where clause to only pick rows with flag, but even then it gives the error.
using a subquery in the from clause eliminates the error, but when i create it in a view it again gives the same error.
My requirment is to find out the period names and transactions which are in valid date formats and are less than sysdate and the non date formats are adjustments made by different users for their transactions
I have a partitioned table with ~50 million rows that was setup with a number(10) instead of a date column. All the data in the table is ALWATS in this format YYYYMMDD
CREATE TABLE T1.monthly ( SEQ_NUM NUMBER(10) NOT NULL, DAY_DK NUMBER(10) NOT NULL ) TABLESPACE USERS PCTUSED 0 PCTFREE 10 [code]........
When I use the exchange partition method the parition is able to move the data from "monthly" table to "mth" table.
desc t1.mth; ### my temorary table Name Null? Type ----------------------------------------- -------- ---------------------------- SEQ_NUM NUMBER(10) DAY_DK NUMBER(10)
Than when I try to alter my temp table "mth". I get an error table must be empty to change column types.
alter table n546830.mth modify (DAY_DK date);
Next I tried making my temporary table "mth" a date column. When I an the exchange partition command I get the following error:
alter table t1.monthly exchange partition DEC_2012 with table t1.mth without validation; alter table n546830.monthly exchange partition DEC_2012 with table n546830.mth without validation * ERROR at line 1: ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION
Method I can use to convert a number(10) to date column and keep the information in a table. Note, I don't care about HH:MM:SS as I never had that information to begin with and would be happy to set that part of the date column to all zeroes "00:00:00"
Is there a seeded function by which I can check all the rows which stored dates in varchar column.
I have a table say test (test_data varchar2(100));
Now I will insert all types of records into the table varchar,number dates and then i will write q query to etch all those records only which has dates only
INSERT INTO test(1); INSERT INTO test('ABC'); INSERT INTO test(SYSDATE); INSERT INTO test(TO_CHAR(SYSDATE,'DD-MON-YYYY')); INSERT INTO test(TO_CHAR(SYSDATE,'DD-MON-YYYY HH24:MI:SS')); INSERT INTO test('15/01/2012'); ... commit;
I have written a trigger & procedure to call a webservice from pl/sql procedure. Everything was working fine until I was told to use nchar & nvarchar2 instead of varchar2 as per requirement. Now I am not able to run the procedure and getting errorcode with return response from server.
I didn't changed the width of columns but only datatype. What precautions do I need to take in code while doing this and what could have caused the error only by converting the data type.
i am fairly new in the oracle arena, but what would cause a statement such as
ALTER TABLE TEST_TABLE MODIFY text_field1 varchar2(100) DEFAULT 'testval' NULL
to change a column's type from VARCHAR2(100) to VARCHAR2(100 byte)? i found a few mentions of the 100 byte concept online but nothing that jumped out at me.
I have table called INFO and the column called CREATED_DATE . Now the datatype of CREATED_DATE is of varchar2 . Now If I need to query the table through select statement where I need to order the result based on CREATED_DATE , how can i achieve this ?
I need loading date formats using sqlldr. I am trying to load some data from another source into our Oracle database, however, the "date" field includes extra characters that i'm trying to deal with. For reference, I'm running Oracle 11.2 on Linux 5.7.
First, the actual date input is:
April 18, 2013 8:50:44 AM EDTI tried to input it a few ways but was unable to load it until I physically removed the "AM EDT" from the input string.
My first question is if there is a way to RTRIM and get rid of those extra characters. Either that, or I need a way to convert the "AM EDT" into our standard date format.
My control file has the following:
LASTCHANGEDAT date "Month dd, YYYY HH MI SS",This will load the data, but only if I strip out the "AM EDT" from the actual data input which is not feasible.
Also, how would I handle date that comes in as: April 18, 2013 3:50:44 PM EDT
Also, I tried the following, but it gives me a different error:
I am trying to insert a row in a table and getting the below error.

I have to change the datatype of a column from CLOB to varchar2, without changing the order of the columns. The table has no data. I could find any other way other than dropping the CLOB columns and then adding new columns with varchar2 datatype. But this changes the order of the columns in the table.
I have table customer which contains a column CUSTOMER_FIRST_NAME
CUSTOMER_FIRST_NAME VARCHAR2(50)
What will be sql statement to add a constraint on the CUSTOMER_FIRST_NAME column of the CUSTOMERS table so that the value inserted in the column does not have numbers ?
I need to create a composite unique index on varchar2, number and CLOB column. I haven't used such index before that have the CLOB column indexing. I found the below link related to CLOB indexing...

Links from where I can get related info. Also I would like to know the impact of such index on performance. I have to store and process around 50 million records in such a way, will it be beneficial to use this index?
I have an index on column of table which of data type varchar2. While selecting data from that table I am using following scenarios in where on the indexed column

I need to create a materialized view with a clob column based on a varchar2 column of a table.This is because in the mv the clob column data gets appended one after another.
How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.
