Converting and to literal strings?
Does anyone know of a free web page for converting a block of HTML to literal strings in order to display it as text in these forums? The one I used to use:
http://www.stanford.edu/~bsuter/js/convert.html
...now has restricted access (or something).
Alancito, I'm guessing that you want to display some HTML without it being rendered as HTML by the forum software?
A really simple method of doing that is to change the < and > brackets to their character entities: < and > .
You can do that quickly in a text editor by doing a search-and-replace, and in reality you only need to change the opening brackets (<) to the < character entity. Then copy and paste the whole block of altered HTML in your post.
For example:
<html>
<head>
<title>your page title</title>
</head>
<body>
<img src="http://images.apple.com/home/images/promoiphone20081103.jpg" />
</body>
</html>
should be changed to the following in a text editor, by simply searching for < and replacing with < :
<html>
<head>
<title>your page title</title>
</head>
<body>
<img src="http://images.apple.com/home/images/promoiphone20081103.jpg" />
</body>
</html>
and when pasted here will look like the first block of HTML in your post.

Using clobs and ORA-01704: string literal too long
Hi,
I am attempting to add oracle support to an existing J2ee application. The issue I am facing is the use of CLOB datatypes and the 4k string literal limitation that Oracle has.
I have dowloaded the 10.2.0.3 thin driver and am connected to a 9i release 2 database. When I execute a statement such as the following (say the table has one varchar2 field and two clob fields
Insert into my_table VALUES ('hi','something','pretend this string is 5000 characters')
I still receive the error
java.sql.SQLException: ORA-01704: string literal too long
I have read that the version 10 drivers were supposed to address this limitation. Is there something I am missing or must I change my home grown database layer to use bind variables or clob manipulation in a separate update/insert statement.? I am trying to avoid this situation since the database layer works fine for the situation of MSSQL and text fields which have no such limitation.
Any advice you have here is greatly appreciated.
Thanks,

Strange problem in converting between XML to string and vice versa
i have an application that needs to send an XML document
over the wire. For this reason, I need to convert the
doc into a String at the sending side and back to Doc
at the receiving side. This document is stored in a "CLOB"
column in a table in the database. I use XDK to retrieve
this entire row (including the CLOB - hence this is an XML
document which has a column that itself is an xml document in
string format - this is just the clob read in by XDK).
Thus the row looks like
<ROWSET>
<ROW>
<col1> A <col1>
<CLOB_COL> ..clob value of an xml doc..</CLOB_COL>
</ROW>
</ROWSET>
When I convert this document into String and back, one of the "<"
tags in the clob column document gets changed to "<" and hence
the parsing fails! I have used the latest label of the XDK build
to get the latest parser jar but still i have the same problem.
I am using the following routines for the conversion.
/* for converting document to string */
public static String convertToString(XMLDocument xml) throws
IOException
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
xml.print(pw);
String result = sw.toString();
return result;
/* for converting string to document */
public static XMLDocument convertToXml(String xmlStr)
throws
IOException,SAXException
ByteArrayInputStream inStream = new
ByteArrayInputStream(xmlStr.getBytes());
DOMParser parser = new DOMParser();
parser.setPreserveWhitespace(false);
parser.parse(inStream);
return parser.getDocument();How do you get the XML document? Do you use XSU? You can use:
String str = qry.getXMLString();
to get the result XML document in String.
XSU will escape all of the < and >. Or the the XML document in
one of the column will make the result XML doc not well-formed.
Not quite understand your problem. You can send me your test
case.

Converting part of the string to a date and subtract with sysdate.
HINT! In order solve this you must know how the pnr is assembled. Study this:
650323-5510, we only need the first six characters. They inform us about when the person (car owner) was born. In this case it is 23 Mars 1965. You have to use several oracle built-in-functions to solve this. Hint! Begin by converting part of the string to a date and subtract with sysdate.
select to_char(to_date(cast(pnr,'YYMMDDMM'))) from car_owner;
please what am i doing wrong. i need the result to be something like this
Hans, Rosenboll, 59,6 years.Hi.
The main problem here is you have only last two digits of year. That could be the problem in a couple of years from now, when somebody born after 2k would get in to your database. For now if we ignore this problem the right solution would be :
<code>
SELECT months_between(trunc(SYSDATE),
to_date('19' || substr('650323-5510',
1,
6),
'YYYYMMDD')) / 12 years_old
FROM dual
</code>
Suppose you are expecting the age of the car owner as a result above code will give you that. One again notice the '19' I appended.
Best regards. -
Cannot convert between unicode and non-unicode string datatypes

HI Subu ,
there is some information gap , what is your source ? are there any transformation in between ?
If its SQL server source and destination and the datatype is as you have mentioned I dont think you should be getting such errors ... to be sure check advance properties of your source and check metada of your source columns
just check simple oledb source as
SELECT TOP 1 ItemCode = cast('111' as nvarchar(50)),DivisionCode = cast('222' AS nvarchar(50)), Salesplan = cast(3.3 As float) FROM sys.sysobjects
and destination as you mentioned ... it should work ...
somewher in your package the source columns metadata is not right .. and you need to convert it or fix the source.
Hope that helps

Hello,
I am working on one project and there is need to extract Sharepoint list data and import them to SQL Server table. I have few lookup columns in the list.
Steps in my Data Flow :
Sharepoint List Source
Derived Column
its formula : SUBSTRING([BusinessUnit],FINDSTRING([BusinessUnit],"#",1)+1,LEN([BusinessUnit])-FINDSTRING([BusinessUnit],"#",1))
Data Conversion
OLE DB Destination
But I am getting the error of not converting between unicode and non-unicode string data types.
I am not sure what I am missing here.
In Data Conversion, what should be the Data Type for the Look up column?
Please suggest here.
Thank you,
Mittal.You have a data conversion transformation. Now, in the destination are you assigning the results of the derived column transformation or the data conversion transformation. To avoid this error you need use the data conversion output.
You can eliminate the need for the data conversion with the following in the derived column (creating a new column):
(DT_STR,100,1252)(SUBSTRING([BusinessUnit],FINDSTRING([BusinessUnit],"#",1)+1,LEN([BusinessUnit])-FINDSTRING([BusinessUnit],"#",1)))
The 100 is the length and 1252 is the code page (I almost always use 1252) for interpreting the string.

Column "A" cannot convert between unicode and non-unicode string data types
I am following the SSIS overview video-
https://secure.cbtnuggets.com/it-training-videos/series/microsoft-sql-server-2008-business-development/6143?autostart=true
I have a flat file that i want to import the contents onto a SQL database.
I created a Dataflow task, source file and oledb destination.
I am getting the folliwung error -
"column "A" cannot convert between unicode and non-unicode string data types"
in the origin file the data type is coming as string[DT_STR] and in the destination object it is coming as "Unicode string [DT_WSTR]"
I used a data conversion object in between, dosent works very well
Please help what to doI see this often.
Right Click on FlatFileSource --> Show Advanced Editor --> 'Input and Output Properties' tab --> Expand 'Flat File Source Output' --> Expand 'Output Columns' --> Select your field and set the datatype to DT_WSTR.
Let me know if you still have issues.
Thank You,

Cannot convert between unicode and non-unicode string data types.
I'm trying to copy the data from 21 tables in a SQL 2005 database to a MS Access database using SSIS. Before converting the SQL database from 2000 to 2005 we had this process set up as a DTS package that ran every month for years with no problem. The only way I can get it to work now is to delete all of the tables from the Access DB and have SSIS create new tables each time. But when I try to create an SSIS package using the SSIS Import and Export Wizard to copy the SQL 2005 data to the same tables that SSIS itself created in Access I get the "cannot convert between unicode and non-unicode string data types" error message. The first few columns I hit this problem on were created by SSIS as the Memo datatype in Access and when I changed them to Text in Access they started to work. The column I'm stuck on now is defined as Text in the SQL 2005 DB and in Access, but it still gives me the "cannot convert" error.
I was getting same error while tranfering data from SQL 2005 to Excel , but using following method i was able to tranfer data. Hopefully it may also help you.
1) Using Data Conversion transformation
data types you need to select is DT_WSTR (unicode in terms of SQL: 2005)
2) derived coloumn transformation
expression you need to use is :
(DT_WSTR, 20) (note : 20 can be replace by your character size)
Note:
Above teo method create replica of your esting coloumn (default name will be copy of <coloumn name>).
while mapping data do not map actual coloumn to the destination but select the coloumn that were created by any of above data transformer (replicated coloumn). -

I am working with a network analyzer. I have arrays made of 5 columns the first consisting of an integer and the next four consisting of complex numbers. I am converting the array into a spreadsheet string and then saving the file using the write characters to a file VI. That seems to work well as when I open the file in Excel all the data is there. However when I try to reverse the process, open file and convert back to array, I loose some of the data. Specifically the imaginary parts of my complex numbers are all going to zero. I have narrowed down the problem to be in the conversion from spreadsheet string to array and vice versa. I
think the problem may be with the 'format' input to the VI. I do not have an adequate resource for this so I am not sure what to put in to accomplish my task. Any takers?Hi Biz
I don't think there is a direct way of converting a complex number to a
string, so when you convert the array to a spreadsheet string, the
numbers would be converted to real data.
However, you could try separating the real and imaginary parts using the
"Numeric: Complex to Re/Im" function, and then store these - either in
separate files or in adjacent columns/rows in the same file. Then, when
you read in the data again, use the "Numeric: Re/Im to Complex" function
to put the two "halves" together.
If you actually want Excel to interpret the numbers as imaginary, then
you'll probably want to create a string for each complex number of the
form "Re + Im*i" (after separating the Re and Im parts), by using
"String:Format into String" with 2 numeric inputs and the format string
"%f+%fi".
Reading the data back into Labview then would require splitting the
string into the 2 pieces by using "Stringcan from String" with 2
numeric outputs (smae precision as original numbers specified by the 2
Default Value inputs) and the same format string "%f+%fi", and then using
the above-mentioned "Numeric: Re/Im to Complex" function. It worked for
me, so if you can't follow what I am describing, send me an email and I
can email you what I did (LV 5.1.1).

Convert a date in String format to a Date

The syntax of the representation of a date/time of day value as character sequence is false. .SQLSTATE=22007I'm pretty sure it won't understand what date.toString() returns. If you know what format the database understands, you do it like this:
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yy"); // e.g. 18-Apr-02
String datestring = sdf.parse(date);
and use that instead of date in your sql string. Some databases understands it if you do
"to_date('18-Apr-02')"
so you could include that in your sql string as well..
You could also try to make it a java.sql.Date and hope your jdbc driver knows how to convert it to a string that the database understands if you don't know the format:
con = getConnection();
PreparedStatement ps = con.prepareStatement("select date1 from table1 where date1 <= ?");
ps.setDate(new java.sql.Date(date.getTime()));

Convert HH:mm:ss String format.
Hi,
I have a formula in webI to display Milliseconds to HH:mm:ss and is in String format.
Is there a way to convert to date or number format?.
Also, how to calculate average of Max and Min time?.
Thanks,
JothiHi Jyothi,
To take a average time do following-
1) Convert Min Time and Max Time into Seconds.
MaxSec=ToNumber(Substr([MaxTime];1;2))*60*60+ToNumber(Substr([MaxTime];4;2))*60+ToNumber(Substr([MaxTime];7;2))
MinSec=ToNumber(Substr([MinTime];1;2))*60*60+ToNumber(Substr([MinTime];4;2))*60+ToNumber(Substr([MinTime];7;2))
2) calculate approximate Avg seconds-
AvgSec=([MaxSec]+[MinSec])/2
3) Convert AvgSec in to hh:mm:ss.
AvgTime=Floor([AvgSec]/3600 )+":"+Floor(Mod([AvgSec];3600)/60)+":"+Mod(Mod([AvgSec];3600);60)
Hope this help.
Thanks,

How to use sed on a literal string containing regex meta characters?
I want to delete the lines from a file which match an arbitrary literal string.
The string is contained in a variable, and may itself contain various regex meta characters such as [,],^,$,|, etc
So, my problem is that sed wants to interpret these meta characters itself. For example:
x='abc[xyz$'
sed -i "/$x/d" file
produces a sed error about the unmatched [, and no doubt it wants to interpret the $ too.
(Of course, I could try and change the string $x so that every possible regex meta character was escaped with a \, but that seems immensely cumbersome. Also, can't see a way of using single or double quotes cleverly.)
Sorry if I am being thick about this, but any ideas or alternative methods would be most welcome!frostschutz wrote:
With sed, you have to escape meta characters indivudually. That's just how it works. Of course you could do the escaping using sed as well, by replacing all meta characters (including \ and /) with \character.
If you want to match strings literally, use a different tool. Or do it in Bash.
while read line
do
[ "$line" != "$x" ] && echo "$line"
done < file
In Perl/PCRE instead of escaping indivudually there is \Q...\E but sed does not understand that, and \Q\E does not solve all problems either, if there is a \E in the $x you have to escape it with \E\\E\Q or something like it.
Thank you for your swift reply. Looks like sed can't be much of a friend in these circumstances!
Probably will have to go with the Bash file handling method.
Oh well ...
