CSV UDF - a UDF for manipulating CSV files

[seangriffin 34]

This UDF provides functions for editing CSV files.

It uses the features of SQLite already existing within AutoIT to open, edit and save data in the CSV format.

Because SQLite is used the performance of the UDF is fast and the functions are accurate.

REQUIREMENTS:

• Windows 64-bit (not tested under Windows 32-bit)
• AutoIt3 3.3 or higher
• sqlite3.exe (included)
• sqlite3.dll (included)

LIST OF FUNCTIONS:

Quote

_CSV_Initialise()
_CSV_Open($csv_file)
_CSV_Exec($csv_handle, $csv_query)
_CSV_GetRecordArray($csv_handle, $row_number_or_query = "", $include_header = False)
_CSV_DisplayArrayResult($csv_result)
_CSV_GetRecordCount($csv_handle)
_CSV_SaveAs($csv_handle, $csv_file, $csv_query = "SELECT * FROM csv;")
_CSV_Cleanup()

EXAMPLES:

Note - To make this example work, you must make sure sqlite3.exe, sqlite3.dll and Item.csv are present in the same folder as the examples.

This is cool. I see you need SQLite for this.. what if the user has SQL Server ?

No this works strictly with SQLite only.  SQLite functions are already included within AutoIT (see the SQLite UDF already inside AutoIT).  But we still need to provide additionally two files - sqlite3.exe and sqlite3.dll.  sqlite3.exe provides the features to import and export CSV files to and from SQLite, and sqlite3.dll is required for all other SQLite functions.

Not working for me. Got it from GitHub today, all the files including the SQLite ones. The example worked except "Get all CSV records with an 'Assigned to' value of 'DELI_SIT_S0004' and display the result ..." didn't display anything and none of the file saves saved (probably Windows). But:

_CSV_Initialise()
Local $item_csv_handle = _CSV_Open("F:\jonf\Documents\Creationism\Dave Hawkins\AF Dave's UPDATED Creator God Hypothesis\Pages.csv")
Local $csv_result = _CSV_GetRecordArray($item_csv_handle, "", False)
_CSV_Cleanup()

fails:

!   SQLite.au3 Error

A typical CSV line is:

http://www.antievolution.org/cgi-bin/ikonboard/ikonboard.cgi"s=5f201cdc628f4c83;act=ST;f=14;t=3131;st=3510,#118_top

??

I did some investigation.  Importing the CSV is failing with result code 21.  Which according to Result and Error Codes means "The SQLITE_MISUSE return code might be returned if the application uses any SQLite interface in a way that is undefined or unsupported."

I added single quotes to all my CSV fields:

'http://www.antievolution.org/cgi-bin/ikonboard/ikonboard.cgi"s=5f201cdc628f4c83;act=ST;f=14;t=3131;st=3510','#118_top'

but that didn't help.
