You didn't show any example of your date or time values, butyou might need to add a space between them, like
To_date(Date || ' ' || time,'dd-mon-yyyy hh24mi')

Convert Varchar to Date

Hi
im trying to convert varchar to date.
So, i used To_date ( cilumn, 'DD-MM-YYYY') , Since i have to order the out put in Decending Order i used the same convertion function with Order by clause.

<sql>
select date_created

select distinct
to_date(created_date,'DD-MM-YYYY') as date_created
from schedule_backup

Hi, Raj,
When you store dates in a VARCHAR2 column, you're asking for touble, so it seems that everything is working according to plan.
Even aside from that, your query works perfectly for me.
In the output you posted, the order is correct within each year, and you're only showing 2 digits of the year. Are you sure the centuries are right in the schedule_backup table? Perhaps everything that was supposed to be '2010' got enetereed as '1910' or '0010'.
Post some sample data (CREATE TABLE and INSERT statements) that gets the wrong results with your query.
For example:
CREATE TABLE schedule_backup
( created_date VARCHAR2 (10)
INSERT INTO schedule_backup (created_date) VALUES ('11-11-2009');
INSERT INTO schedule_backup (created_date) VALUES ('04-11-2009');
INSERT INTO schedule_backup (created_date) VALUES ('30-10-2009');
INSERT INTO schedule_backup (created_date) VALUES ('11-09-2009');
INSERT INTO schedule_backup (created_date) VALUES ('04-03-2010');
COMMIT;

Convert VARCHAR to date - don't know format in advance

Hi,
If I want to convert varchar to date, but I don't kniow the format of the varchar in advance. For example, it may be '20-MAY-99', '2009-01-10 10:01:00', but it is not known in advance. How can I convert it to date?
Many thanks

You'll have to define a hierarchy of date formats to try. There are some strings that map to many different valid dates depending on the format. The string '01/02/03' might translate to January 2, 2003, January 2, 1903, February 1, 2003, February 1, 1903, February 3, 2001, February 3, 1901, etc.
Assuming you define a hierarchy of formats, you can write a function that tries each format in turn, i.e.
CREATE FUNCTION my_to_date( p_string IN VARCHAR2 )
RETURN DATE
IS
l_date_variable DATE;
BEGIN
l_date_variable := to_date( p_string, <<format 1>> );
return l_date_variable;
EXCEPTION
WHEN OTHERS THEN
    BEGIN
      l_date_variable := to_date( p_string, <<format 2>> );
      return l_date_variable;
    EXCEPTION
      WHEN OTHERS THEN
END;You'll need to define the N date formats to try and the order in which to try them.

Convert varchar(20) date to date that looks like mm/dd/yyyy

Good afternoon,
I am a total novice at SQL and have been tasked to change a varchar(20) date column (shows up as m/dd/yy) to show up as mm/dd/yyyy. I've looked at the previous posts, but being a novice, it's difficult to wade through the non-applicable stuff. The column
that needs to be changed is field2, but I'm not sure how to construct a statement to reflect my objective.
Thank you in advance.

The sample uses a table variable. You can program it the same way for a table:
DECLARE @t TABLE (dt VARCHAR(20))
INSERT INTO @t
VALUES ('1/2/12')
,('3/10/10')
,('7/23/9')
,('aa')
,('12/31/99')
,('10/20/00')
,('10/20/01')
SET DATEFORMAT mdy
SELECT dt
,CONVERT(VARCHAR(10), CASE
WHEN isdate(dt) = 0
THEN NULL
ELSE cast(dt AS DATE)
END, 101) AS newDt
FROM @t;/******** TRY_CONVERT() method ************/
SELECT dt, newDt=CONVERT(varchar(10),TRY_CONVERT(date,dt),101) FROM @t;
GO
dt newDt
1/2/12 01/02/2012
3/10/10 03/10/2010
7/23/9 07/23/2009
aa NULL
12/31/99 12/31/1999
10/20/00 10/20/2000
10/20/01 10/20/2001
dt newDt
1/2/12 01/02/2012
3/10/10 03/10/2010
7/23/9 07/23/2009
aa NULL
12/31/99 12/31/1999
10/20/00 10/20/2000
10/20/01 10/20/2001
Starting with SQL Server 2012 you can use TRY_CONVERT().

How to convert varchar to date?

Hello everyone, I'm new to OBIEE and I'm running into a roadblock...
I have a date that is stored in a varchar2 column in the physical table, like so: 20071225
Silly I know, but that's what I'm dealing with.
Anyway, I want to create a logical column in the business model (using the Administration tool) and convert it to a date so that I can do date arithmetic with it, but TO_DATE doesn't seem to be supported.
In Oracle SQL would do this (I'm using XE):
SELECT SYSDATE - TO_DATE('20050101', 'YYYYMMDD') FROM DUAL
Is there any way to accomplish this same thing in the OBIEE? I see the CAST function, but there doesn't seem to be any way to cast a string to a date?

The original post is 4 years old - I am sure the poster must have figured it out by this time... obiee 11g supports a To_Datetime function though! thanks!

Convert varchar to date in BO Universe with Substring and instring function

to_date(substr(xxxx_v.e_details,instr(xxxx_v.e_details,'|',1,2)+1,9),'DD-MM-YYYY') In the universe while defining the object as date i was facing probs can any body help me out. the column xxxx_e_details is having the datatype varchar in database and the third string is date while i was creating the date object in the universe with the above syntax it was getting the error
The data in this obect is like this xxxx_v.e_details -> wwww|eeee|MM-DD-YY|
Edited by: mohammed kashif on Mar 31, 2011 11:47 AM

i am getting the data but it is in the format 01-03-0201. The year format for 2010 is populating as 0201. i am not able to think whether it is due to instring function which is reading data like this. Need suggestion from experts.............

Converting varchar to date

Hi All
when i run the below select statement i get error message. pay_dt is varchar2(8) data type.
ORA-01861 : literal does not match format string
Any help on this appreciated. Thank you very much.
SELECT DISTINCT to_char(to_date(pay_dt

,'MON')

Mahir M. Quluzade wrote:
Your pay_dt datatype varchar2(8), but your gived format YYYY-MM-DD length is 10.
Change yor format please to 'YYYYMMDD' or 'DDMMYYYY' or 'MMDDYYYY' or 'YYYYDDMM' for your payments.pay_dt data.
for examle : pay_dt is '20010528' then use 'YYYYMMDD'unfortunately probably not the case - oracle is surprisingly forgiving with dates and will ignore any separators you add in your format mask if it can still convert it.

1 row selected.I'd recommend searching through the data to find the record(s) that are completely around the wrong way or contain invalid characters etc.

Question - new to BO Data Services Designer - how to automatically transform varchar column data to upper(varchar) across all columns in a table?

Hello -
New user to BO Data Services Designer. Company is using Data Services Version 12.2.
I have many tables that all need the same transformation- converting varchars fields to upper(varchar) fields
Example:
I have a table called Items. It has 40 columns, 25 of which are of type varchar.
What I have been doing is ....
I make the Item table as the source table then create a Query transform that is then attached to a new target table called - ITEMS_Production.
I can manually drag and drop columns from the source table to the query and then in the mapping area I can manually type in upper(table_name.column_name) or select the upper function and then select the table.column name from the function drop down list.
Obviously, I want to do this quicker as I have to do this for lots and lots of tables.
How can set up Data Services so that I can drag and drop an upper transform quickly and easily or automate this process.
I also know Python-Java so am happy to script something if need be.
the logic would be something like -
if there is a column with a type varchar, add the upper() transformation to column. Go to next column.
Excited to be using this new tool-
Thanks in advance.

Convert varchar(255) to varchar(50)

I want to transfer data from a staging table to another table. The staging table has columns with datatypes I don't always want, and I'm converting them like so:
INSERT INTO [dbo].[my_table]
SELECT CONVERT(datetime,TimeIndex,103),
CONVERT(decimal(6,3),Network_In,3),
CONVERT(decimal(6,3),Network_Out,3),
CONVERT(decimal(6,3),Network_Total,3)
FROM [dbo].[staging_table]
How would I convert varchar(255) to varchar(50)?
Thanks in advance
Adam

Using substring is returning the column so thanks but now I can't convert datetime for some reason:
INSERT INTO [dbo].[mytable]
SELECT SUBSTRING(ClusterName,1,50) AS 'ClusterName',
CONVERT(datetime,TimeIndex,103),
ClusterID,
CONVERT(decimal(3,2),Memory,3),
CONVERT(decimal(3,2),CPU,3),
CONVERT(int,CPUTotal),
CONVERT(int,MemoryTotal)
FROM [dbo].[stagingtable]
GO
Now I get an error I didn't get before:
Implicit conversion from data type datetime to decimal is not allowed. Use the CONVERT function to run this query.
But if I run the datetime convert on it's own as a single column select then it works okay. Any ideas where I've gone wrong there?
To sum up - the above fails but the below works:
SELECT CONVERT(datetime,TimeIndex,103) AS 'TimeIndex'
FROM [dbo].[stagingtable]
Thanks

Converting varchar to datetime 103

Hi Guys
Im making a select query where in a colomn the date is yyyy-mm-dd, i need dd-mm-yyyy (103). A simple convert query does not work because the colomn is not set as a datetime but as a varchar. Its not possible to change the tables at the source.
The colomn name is DATE_IN
I think the following post could be helpfull but i dont know how to fix the given statements into the select query
http://stackoverflow.com/questions/1509977/convert-varchar-into-datetime-in-sql-server

> in a colomn the date is yyyy-mm-dd, i need dd-mm-yyyy (103)
As suggested above, this is string date format to string date format conversion, purely string operations.
If you convert to DATE / DATETIME first (universal internal binary representation), then it may fail if invalid date.
You can use the ISDATE or TRY_CONVERT functions to check if the string date is valid.

Convert varchar to decimal - arithmetic overflow

I'm using SQL Server 2014 and I'm trying to convert data from a staging table over to a production table. I seem to be getting an Arithmetic overflow error converting varchar to numeric on the decimal conversion. I'm sure I've overlooked something with the
syntax of the CONVERT.
This is the staging table:
CREATE TABLE [dbo].[staging_table](
[TimeIndex] [varchar](100) NULL,
[Cluster] [varchar](100) NULL,
[AvgMem] [varchar](100) NULL,
[AvgCPU] [varchar](100) NULL,
[TotalMemory] [varchar](100) NULL,
[TotalCPU] [varchar](100) NULL,
[Datacenter] [varchar](100) NULL,
[vCenter] [varchar](100) NULL
) ON [PRIMARY]
This is the prod table I'm moving it to:
CREATE TABLE [dbo].[Clusters](
[ClusterID] [int] IDENTITY(1,1) NOT NULL,
[ClusterName] [varchar](25) NULL,
[DatacenterName] [varchar](25) NULL,
[TimeIndex] [datetime] NULL,
[AvgCPU] [decimal](5, 2) NULL,
[AvgMem] [decimal](5, 2) NULL,
[TotalCPU] [decimal](8, 2) NULL,
[TotalMem] [decimal](8, 2) NULL,
[vCenterID] [int] NULL,
CONSTRAINT [PK_Clusters_1] PRIMARY KEY CLUSTERED
[ClusterID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
and here's an example INSERT INTO statement throwing the error:
INSERT INTO [dbo].[Clusters] (ClusterName,DatacenterName,TimeIndex,AvgCPU,AvgMem,TotalCPU,TotalMem,vCenterID)
SELECT SUBSTRING(Cluster,1,25) AS ClusterName,
SUBSTRING(Datacenter,1,25) AS DatacenterName,
CONVERT(datetime,TimeIndex,103) AS TimeIndex,
CONVERT(decimal(5,2),AvgCPU) AS AvgCPU,
CONVERT(decimal(5,2),AvgMem) AS AvgMem,
CONVERT(decimal(8,2),TotalCPU) AS TotalCPU,
CONVERT(decimal(8,2),TotalMemory) AS TotalMem,
'3' FROM [dbo].[staging_table]
Sample data is 0.00 to 100.00 in fields AvgCPU and AvgMem, and TotalCPU and TotalMem usually goes up to about 7 digits with no decimal (eg. 7543253) but could be 8 and although I've never seen a decimal I wouldn't rule it out so decided to account for it.
I assume it's something I've overlooked with the syntax but any ideas would help.
Thanks
Adam

The problem is your precision and scale you are assigning to your decimals.
decimal(5,2) = this is a total of 5 digits, 3 digits for the whole number and 2 for the fractional.
decimal(8,2) = this is a total of 8 digits, 6 digits for the whole number and 2 for the fractional.
So converting a varchar of 7 or 8 digits for TotalCPU or TotalMem will give you an error because your definition will actually only allow for 6 digits of storage. You could test this by doing decimal(8,0) or decimal(10,2) both which will allow for up to
8 whole numbers.
If you are worried about space Sql Server will allocate a set number of bytes for ranges based on the precision (first number in the parenthesis). See this page which explains in detail how much space each range takes up and also further details on
decimal and numerics.
