I had lots of data in a .rtf file(having usernames and passwords).How can I fetch that data into a table. I'm using sqlite3.
I had created a "userDatabase.sql" in that I had created a table "usersList" having fields "username","password". I want to get the list of data in the "list.rtf" file in to my table "usersList". Please help me .
Thanks in advance.

I would write a little parser. Re-save the .rtf as a txt-file and assume it look like this:
user1:pass1
user2:pass2
user5:pass5
Now do this (in your code):
open the .txt file (NSString -stringWithContentsOfFile:usedEncoding:error:)
read line by line
for each line, fetch user and password (NSArray -componentsSeparatedByString)
store user/password into your DB
Best,

Edit: for parsing excel-sheets I recommend export as CSV file and then do the same
Parsing RTF files is mostly trivial. They're actually text, not binary (like doc pdf etc).
Last I used it, I remember the file format wasn't too difficult either.
Example:
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Calibri;}}
{\*\generator Msftedit 5.41.21.2510;}\viewkind4\uc1\pard\sa200\sl276\slmult1\lang9\f0\fs22 Username Password\par
Username2 Password2\par
UsernameN PasswordN\par
}
Do a regular expression match to get the last { ... } part. By sure to match { not \{.
Next, parse the text as you want, but keep in mind that:
everything starting with a \ is escaped, I would write a little function to unescape the text
the special identifier \par is for a new line
there are other special identifiers, such as \b which toggles bolding text
the color change identifier, \cfN changes the text color according to the color table defined in the file header. You would want to ignore this identifier since we're talking about plain text.

I have text file which is having ^(CAP) and ,(Comma) as a delimiter and after clearing i need to load to sql . I have tried my best to clear a source file
But still file is not cleaned as expectation .
Please find the below picture i have tried to correct the source file
But still file is not cleared as expected . Please find below uncleared file .
You have a variety of issues here.
You have identified the header row delimiter as a comma. A row delimiter is the, usually invisible, delimiter than indicates a row's worth of data has happened. Traditionally, this is an Operating System specific value but it's a Carriage Return (CR), Line Feed (LF) or Carriage Return/Line Feed.
Your source data is not a comma delimited file with caret/circumflex/cap text delimiters. You have a comma-space delimited file which SSIS doesn't support in the editor. However, if you hand edit the dtsx file as I outlined in How to read a flatfile with lowercase thorn as the delimiter to specify that it should use comma space ColumnDelimiter="_x002C__x0020_"
Given a truncated version of your source data
ListCode, CAS, Name
^216^, ^^, ^Coal Dust^
^216^, ^7782-24-5^, ^Graphite (Natural)^
^216^, ^^, ^Inert or Nuisance Dust^
and the comma (0x2C) space (0x20) edited into the raw dtsx connection manager, I was able to pull data as I believe you are expecting
You might also run into additional issues given your selection of code pages and not checking the Unicode button but that's beyond my ability to generate matching source data from an image.
Just replace the ^, ^ with ^,^
It looks like your source
CAS, SubName, ListCode, Type, CountryCode, ListName
^1000413-72-8^,^fasiglifam^,^447^,^Chemical Inventory^,^EU^,^ECICS Custom Tariff Codes^
^1000413-72-8^,^fasiglifam^,^0^,^^,^NN^,^SPHERA Global Substance List^
Then edit your connection manager with below details

It will work .

I uploaded a wav and text file to the custom speech portal. I got the following error: “Error: normalized text is empty.”
The text file is UTF-8 BOM, and is similar in format to a file that did work.
How I can trouble-shoot this?
There can be several reasons for a normalized text to be empty, e.g. if there are words of Latin and non-Latin characters in a sentence (depending on the locale). Also, words that are repeated multiple times in a row may cause this. Can you share which locale you're using to import the data? If you could share the text we can find the reason. Otherwise you could try to reduce the input text (no need to cut the audio for this) to find out what causes the normalization to discard the sentence.
I'm using SQL file table and for instance I have a saved text file named "SOS.txt" which contains following text
For god's sake, save us right now please. We can't survive.
Now or never!
Now I want to find all files that contain the word save, so I execute following query
SELECT * FROM FileTableExample
WHERE CONTAINS(file_stream, 'save')
and here's the result:
stream file => 0x616C692053617665207573207269676874206E6F772E0D0A4E6F77206F72206E6576657221
As you can see I got the true result, the third column of the result indicates the file under name SOS.txt, I have the stream_id and stream_file but what I'm about to find is the way to show the the intended text in company with it's surrounding in human readable format.
Somethings like this:
Name | Excerpt
-------------+----------------------
SOS.txt |..sake, save us..
Is there any way?
Update:
After searching on the net I found this article which is useful but it didn't mention about full text search in filetable structure.
Based on this article, I converted file stream to string:
SELECT CONVERT(varchar(MAX), file_stream) AS Excerpt, *
from FileTableExample
where contains(file_stream, 'save')
It works if the file is a plain text like SOS.txt but if it's .docx or .pptx file, you are not going to gain a useful convention.
Use this, CAST(file_Stream as varchar(max))
I have an input file that I want to use the string SPLIT function on for each line, depending on the Type field. However, the description field sometimes has data that has new lines in it so it messes up my file reader since it uses streamreader's readline() function
Handled:
Type|Name|User|Description
Type|Name|User|Description
Unhandled:
Type|Name|User|Description line 1
Description Line 2
Type|Name|User|Description
Besides not being able to validate on 'Type' for each line and keep reading the file for when the next Type field appears, are there any ways folks can come up with to properly read this file?
My solution was to have the file maker replace newline characters in their description field with another unique character that I can later add back in. I'm still interested in solutions from the file reader's perspective though
I know I'm talking to myself a lot here, but I found another solution, which is to remove remove line feeds, since the output file creator wrote out carriage returns for each line.
You could easily set a conditional statement to see if the Split array contains more than one element, which would indicate that it's a line you want to parse.
Could anyone please share how to write bold text to a .dat file using something similar to the below or otherwise in PL/SQL?
UTL_FILE.PUT_LINE(FPOINTER,'i want this in bold');
I think I maybe wrong but you can't do text with styles with UTL_FILE. .dat usually is used for information only, and its representation (like bold texts) is not part of it.
However you can save file as HTML and put lines like '<b>'|| 'my text here' || '</b>'
