Convert Column from Varchar to NVarchar

Hi Guys,
i know we cannot alter a columns datatype when there is a data. but the problem is that i would like to alter a datatype with the data in database. as there is no downtime to our server. im not sure this can be achieved, but i feel someone might have faced this kind of problem. even we cannot create new columns and then dump the data there and then delete the old columns as the data is huge.
please advice.
thanks
Fairozkhan

Derived column transformation from varchar(8) YYYYMMDD to DATETIME column

It seems I have tried everything, but all I need to do is change a column from varchar(8) to DATETIME. Some lines are blank, zero length strings, and some have dates such as 20140829. All the rows go to an exception table or it just bombs altogether. The
only thing I can get to run is NULL(DT_DATE), but obviously, that won't work in the end.
I tried LTRIM(RTRIM(MyDateColumn) == "" ? (DT_DATE)"1900-01-01" : (DT_DATE)(SUBSTRING(MyDateColumn,1,4) + "-" + SUBSTRING(MyDateColumn,5,2) + "-" + SUBSTRING(MyDateColumn,7,2))
I got truncation errors on that.
Sometimes I got an error: An error occurred while attempting to perform a type cast.
I tried DT_DATE, DT_DBDATE and DB_DBTIMESTAMP
I even tried putting GETDATE() in there or a literal date such as "2014-08-29" like (DT_DBDATE)"2014-08-29"
This wouldn't even compile: MyDatCeolumn == "" ? NULL(DT_DBDATE) : (DT_STR,10,1252)((DT_DBDATE)MyDateColumn)
I tried many variations on these. I either got truncation errors or the transformation would turn red and stop, or the expression wouldn't work (turns red when you leave the row).
Review:
Source MyDateColumn VARCHAR(8) NULL; Target MyDateColumn DATETIME; Source values in format of "" (blank) or "20140829". The blanks should end up null, or maybe a literal date like Jan 1, 1900, and the actual dates should be transformed
to DATETIME.
Should not be that hard. Thanks in advance for help.

Hi duanewilson,
Please create a Derived Column transformation and a new column, then use the following expression for the expression field:
(DT_DATE)(SUBSTRING([MyDateColumn],1,4) + "-" + SUBSTRING([MyDateColumn],5,2) + "-" + SUBSTRING([MyDateColumn],7,2))

Converting Column to Rows

Hello,
I am trying to build and SQL to convert columns from multiple rows to the all rows - see below test data and result expected:
CREATE TABLE XX_TEST(NAME VARCHAR2(10),A1 VARCHAR2(10),A2 VARCHAR2(10), A3 VARCHAR2(10),A4 VARCHAR2(10),A5 VARCHAR2(10));
INSERT INTO XX_TEST VALUES('LIST','A','B','C','D','E');
INSERT INTO XX_TEST VALUES('L1','1',NULL,'3',NULL,NULL);
INSERT INTO XX_TEST VALUES('L2','1','5','4',NULL,NULL);
COMMIT
SELECT * FROM XX_TEST;
Result expected:
NAME is Column from table XX_TEST but COLUMN and VALUE are the columns converted to rows-
NAME COLUMN VALUE
L1 A1 1
L1 A2 NULL
L1 A3 3
L1 A4 NULL
L1 A5 NULL
L2 A1 1
L2 A2 5
L2 A3 4
L2 A4 NULL
L2 A5 NULL
Thanks

Hi,
Thanks for posting the sample data in such a useful form!
Whenever you post a question, you should always say what version of Oracle you're using, too.
Displaying multiple columns from one row as one column on multiple rows is called Unpivoting .
In Oracle 11, you can use the SELECT ... UNPIVOT feature to do that.
In any version of Oracle, you can cross-join your table to a Counter that has as many rows as your original table has columns to be unpivoted.
In this problem, we need a self-join of the unpivoted data, to join the rows with name='LIST' to every other row.
WITH     cntr     AS
     SELECT     LEVEL     AS n
     FROM     dual
     CONNECT BY     LEVEL     <= 5
,     unpivoted_xx_test     AS
     SELECT     x.name
     ,     'A' || c.n     AS col
     ,     CASE c.n
               WHEN 1     THEN x.a1
               WHEN 2     THEN x.a2
               WHEN 3     THEN x.a3
               WHEN 4     THEN x.a4
               WHEN 5     THEN x.a5
          END          AS val
     FROM          cntr     c
     CROSS JOIN     xx_test     x
SELECT       u.name
,       u.col
,       l.val          AS val1
,       u.val          AS val2
FROM       unpivoted_xx_test     l
JOIN       unpivoted_xx_test     u ON     l.col     = u.col
WHERE       l.name     = 'LIST'
AND       u.name     != 'LIST'
ORDER BY name
,       col
;Output:
NAME       COL VAL1       VAL2
L1         A1 A          1
L1         A2 B
L1         A3 C          3
L1         A4 D
L1         A5 E
L2         A1 A          1
L2         A2 B          5
L2         A3 C          4
L2         A4 D
L2         A5 EThe query above uses some features that were new in Oracle 9, but the basic strategy will work in earlier versions.
If your columns don't have such regular names (A1, A2, A3, ...) then you can use another CASE expression to derive unpivoted_xx_test.col.

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> I need to select from a dynamic column name and save the result in a variable, but seem to be having trouble with the values being fed to sp_executesql <<
This is so very, very wrong! A column is an attribute of an entity. The idea that you are so screwed up that you have no idea if you want
the shoe size, the phone number or something else at run time of this entity.
In Software Engineering we have a principle called cohesion that says a model should do one and only one task, have one and only one entry point, and one and only one exit point.
Hey, on a scale from 1 to 10, what color is your favorite letter of the alphabet? Yes, your mindset is that level of sillyity and absurdity.
Do you know that SQL is a declarative language? This family of languages does not use local variables!
Now think about “month_val” and what it means. A month is a temporal unit of measurement, so this is as silly as saying “liter_val” in your code. Why did you use “sp_” on a procedure? It has special meaning in T-SQL.
Think about how silly this is:
SET @month_val = 'Month' + CAST(@month_nbr AS VARCHAR(2));
We do not do display formatting in a query. This is a violation of at the tiered architecture principle. We have a presentation layer. But more than that, the INTERVAL temporal data type is a {year-month} and never just a month. This is fundamental.
We need to see the DDL so we can re-write this mess. Want to fix it or not?

To convert the values in the column from upper case to Camel Case.

Hi All,
I have requirement to convert the column values(Data in the Columns) from upper case to camel case in pivot table view.
For Eg:
I have
Table Name:Billing_Transaction
under Billing_Transaction table i Have column Comment_Text
Data in Comment_Text Column is
INSERT,
EXPORT,
AMEND
How i will change these values in to Insert,Export,Amend.(Camel Case condition)
I want only the first letter of a word to be in caps and others to be in smaller case.
Thanks,
Chitra Subramani.

Hi Aravind,
Thanks for immediate response.your query is helpful.But i need to satisfy another condition in my requirement by using same formula.
"REPLACE(UPPER(SUBSTRING(BILLING_TRANSACTION.BILLING_TRANSACTION_DESC FROM 1 FOR 1)) || lower(substring(BILLING_TRANSACTION.BILLING_TRANSACTION_DESC FROM 2)), '_', ' ')"
above query satisfying Camil case and replacing '_' with ' '(space)......but inthis query i want add another condition to satisfy camil case for word which comes after '_'
for example:
DECLINE_IMPORT
above query satisfying 2 conditions to convert above data into
"Decline import"
But in my requirement for word 'import' also it should come in camil case condition like
"Decline Import"
Thanks & Regards,
Chitra

How to import decimal values from Excel to nvarchar column correctly?

I have SQL Server 2012 Integration Services. I have Excel Source and OLE DB Destination.
I have 2 Excels, both having exactly same columns and their destination table is same.
I have MarketShare column in Excel. I have also MarketShare column nvarchar(100) in Database. I should not make any change in Excel file or DB table.
MarketShare value can be numerical like "0.50" or "25.4" or text like "Not Available" or text like "Not Available Yet"
My problem is that numerical values are stored to DB like 0.500000000000003, 25.399999999999999. Text as stored correctly.
What should I do so that digits of numerical values are stored corretly to nvarchar(100) column?
Kenny_I

Hi Kenny_I,
I am unable to reproduce the issue in my test environment no matter it is a XLS file or a XLSX file. After adding extended property “IMEX=1” to the ConnectionString of the Excel Connection Manager, the connection string should be as follows:
For XLS file:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Temp\Test.xls;Extended Properties="EXCEL 8.0;HDR=YES;IMEX=1";
For XLSX file:
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Temp\Test.xlsx;Extended Properties="EXCEL 12.0 XML;HDR=YES;IMEX=1";
If we open the Advanced Editor for the Excel Source, and expand the Output Columns node, the data type of the MarketShare column should be to DT_WSTR with 255 length. Because the length of the destination column in SQL Server table is 100,
we need to change the length of the output column from 255 to 100. There may be a warning about data truncation thrown by the Excel Source but we can ignore this warning.
If the above steps doesn’t work, please post more information about this package for further investigation. Please post the data type of the Output Column MarketShare of the Excel Source as well as the Input Column MarketShare of the OLE DB Destination.
Besides, click the path between the Excel Source and OLE DB Destination and click “Enable Data Viewer”. Then, run the package to check whether the data displayed in the Data Viewer are the same as the source data (like 0.50) or the same as the data inserted
to the SQL Server table (like 0.500000000000003).

Converting text to varchar in a variable

hi all,
i am getting CUSTMER_ID like ('1234','23456','23445','9845'.....) almost 3k Customers in single row, i am selecting this from a table a running through execute SQL task and capturing the result in a variable , but when i try
execute the task i am getting the error saying variable value is differs from the current variable. i converted the column to varchar(max) but no use.
please help me to solve this issue , any help will be appreciated.

SSIS doesn't recognize VARCHAR(MAX). So,
Try using SELECT CAST(CUSTOMER_ID AS VARCHAR(8000)) Cust_ID FROM YourTable and map this "Cust_ID" column in Result Set.
If your result is exceeding the limit, store it in Object variable.
Later you can access Cust_ID by using ForEach Loop or using Script Task.

I have table called Employe. And the Columns are Emp_ID,EMP_NAME,SRC_SYS_CD,DOB
I have Query like
Select

XML Column from table extract to Pipe Delimited Text File

Hi,
I have an XML column with large data in a Table ( Source SQL server Database).
I was asked to extract XML column to .txt file using SSIS.
Is it possible to extract xml column with huge data to text file ?
when I tried, select XML column from Table in source , I noticed that Property of column is taken as [DT_NTEXT] . I Converted it to DT_TEXT as Ansi donot support DT_NTEXT.
Execution method was success but it failed due to trucation. so wondering is there a way to get XML column extracted to Pipe delimited text file?
Is it advisable to do this ? or IS It Valid to export XML in Pipe Delimited File ?
Please Kindly advice
thanks
kodi

Are you looking at shredding data within XML nodes and then importing it to text file or are you looking at exporting XML value as is? Also is SSIS a necessity?
If not, You can simply use T-SQL for this along with bcp for this. just use a query like
EXEC xp_cmdshell 'bcp "SELECT CAST(XMLColumn AS varchar(max)) AS Column FROM table" queryout <full file path> -c -S <ServerName> -T -t |'
provided you use trusted connection (windows authentication)
see
http://visakhm.blogspot.in/2013/10/bcp-out-custom-format-data-to-flat-file.html
If you want to shred the data use Xpath functions in the query as below

Error converting data type varchar to numeric - maybe non printable character?

Hello all. I'm having some trouble converting a column in my table from varchar(50) to decimal(20,4). I've also tried to convert it to int and had no luck. In trying to find the records with non numeric data, I ran this query...
SELECT *
FROM [table]
WHERE [column] not like '%[^0-9]%'
My result set was 32 rows where the field in question had zeros. This doesn't make sense to me. If it was a real zero, it would have been excluded from the query.
So, I flipped it around and ran the following query, and got the same results.
SELECT *
FROM [table]
WHERE [column] = '0'
If it's really a string 0, what would keep it from converting to a numeric type? I'm wondering if there are non printable characters in there because this table was populated via SSIS package using a flat file.
Thanks for any help you can provide!
WeeLass

I have discovered one of the values that will not convert. It is '-1.2317 ' and I tried RTRIM and those trailing spaces stay there.
It has a length of 8, and ASCII value of 45, and converting to varbinary gives 0x2D312E3233313709.
The 45 and 2D both point to a negative sign. This one does indeed have a negative sign, but it's in the front, not trailing. Also, another value that was failing was not negative, but did have the trailing spaces.
Any ideas on how to figure out what those spaces actually are? Hopefully, if I know that, then I can know how to get rid of them.
WeeLass
It may be a hard space
RTRIM trims only soft spaces
try this and see if works
REPLACE(ColumnName,CHAR(160),'')

How to I convert data from oracle database into excel sheet

how to I convert data from oracle database into excel sheet.
I need to import columns and there datas from oracle database to microsoft excel sheet.
Please let me know the different ways for doing this.
Thanks.

asktom.oracle.com has an excellent article on writing a PL/SQL procedure that dumps data to an Excel spreadsheet-- search for 'Excel' and it'll come up.
You can also use your favorite connection protocol (ODBC, OLE DB, etc) to connect from Excel to Oracle and pull the data out that way.

Excel & ActiveX: Insert arbitrary columns from 2D array and create graph problems

Hi there,
I want to insert data from either a 1D or 2D array from LabView into Excel and create graphs.
I used the information from the following example:
http://www.ni.com/example/28934/en/
and was able to create a new Excel file (I'm using Excel 2010), writing data from an 1D array to a column in excel by creating a while loop and using the first element of the array to write it to a specific cell. I use the counter of the loop to write to the next cell when the loop starts over and always delete the first value, which I write to the cell, from the array until it is empty.
Now I also would like to write a 2D array - so the first column in Excel should be the first column from the array and so. Here I cannot use the loop counter directly as Excel only counts 1,2,... for the rows, but uses A,B,... to count columns. Also I do not know in advance how many columns my 2D array will contain, so creating a lookup table like (A means 1, B means 2,...) is not really an option (except there really is no other way). Is there a possibilty to convert numbers into letters or some way to 'explain' to the program that column 2 in the array means column B in Excel for example, or is there a way to insert new columns?
I figured out how to add new Worksheets and as I also need to create a certain number of Worksheets and I know that on standard 3 sheets are present when creating the file, I use the 'add' methode to create every new worksheets before worksheet 3 - I could use the same methode to create new columns in Excel, but so far I didn't find a methode to do so. Or is there a way to enter the whole 2D array at once?
Then I'd like to create a graph (in case of the 1D arrays a bar plot, when using 2D arrays a 3D plot) to view the data. I found this example:

-> as I do not have the toolkit I'd like to do it using ActiveX directly, so I tried to do things like shown under the headline 'DIY ActiveX/.NET'
I tried to load the snippet to a new Excel file but got the error message 'microsoft.office.interop.excel.dll not found' and hence the code is not working. That confuses me a little as I would guess when this dll is not present I cannot access Excel from LabView at all, though my understanding of what I'm really doing so far is quiet limited. ;-)
Also - as far as I understand from the snippet - when creating a new chart object I should be able the create methodes for it, however when I do a right click on the chart object of an ActiveX Worksheet symbol there are none listed.
To explain my problems better I added a snippet showing my two problems: The inner of the two while loops shows how I import a 1D array. In the outer loop I seperate the columns. I know that currently this is not working as all data end up in column A of the Excel sheet - so I would need to convert the number of the outer counter to A, B,... or find a different solution.
Moreover on the snippet I placed an ActiveX Worksheet Property with the Chart Object - as I can see the difference to the Chart Object in the example code from the last link above is the color. However I'm not sure what that means and how to change/ solve this.
And just to make sure - I know this way the VI does not run as the Chart Object is placed completely wrong - I just did it, so it is included in the snippet.
I'd be thankful for any suggestions,
Thanks!
Solved!

Hello everyone and thanks for the answers.
I only have the LabView Student Edition available here - is the toolkit included in it too. How can I check if it is installed/ available and in case it is installed - where can I find it?
Today I had time to take a look at the example
Create via ActiveX Labview a XY Scatter plot graph on an excel sheet
It almost does what I want in terms of creating a graph. The only problem I could not fix, is that in this example a sheet is created where only the graph is present. i'd like to add the graph to a previously created worksheet. Today I tried get this working but it seems I stilll don't really understand what I'm doing, I'll post a snippet of my code as soon as I can access the PC with LabView on it again.
I also took a look at the other example for inserting 2D attays - it seems to be what I need, I just had no time so far to test it, I'll post an update when I could test it.
Thanks for the help so far!

Desc doesn't show datetime columns from SQl Server

Hi Everyone,
I have working db link to sql server using hsodbc:
Oracle 10.2 on AIX using freetds odbc driver version 0.82.
I can access tables on sql server but oracle sees only varchars and numerics columns in a table.
Is there a way to select datetime columns from sql server using hsodbc?

when hsodbc does not show a certain data type it is commonly related to the fact that HSODBC doesn't support the related ODBC data type.
In general you have a data type in your SQL Server which is mapped to an ODBC data type by the ODBC driver. HSODBC then maps the ODBC data type to an Oracle equivalent and when the ODBC data type isn't supported by HSODBC it just drops it from the select list.
So for a root cause analysis an ODBC trace is required to determine the mapping of the FreeTDS ODBC driver.
With this info we can then compare the mapping documented in the HSODBC manual and if the ODBC data type isn't listed as a supported data type you then need to cast the data type on the source side to a different data type (for example varchar/char).
So please post the ODBC trace and I'll have a look.

A way to convert selection from query builder in DML language

I search a way to convert selection from query builder in DML language.
regards

We will make a sample from this request and post it on OTN. I have pasted all the JSP code so you should be able to use it directly. Just change the BISession details and the presentation references.
