Create CSV from Log File

Question

I have a set of logs that that I need to run some analysis on. I'm trying to convert them to a CSV format so I can analyze them with Excel or LogParser.
The basic process I'm trying to implement is:
1. Search entries for ERROR in log file
2. Split components of the error line
3. Create output CSV.
I was able to address item 1 with this this statement:
Select-string -path C:\my\logfile\file.log -Pattern "\W\sERROR:\s" -CaseSensitive -AllMatches | select -expand line
This is a sample of the output lines I'm getting
01/31/2014 14:07:00 USERC <25000> ERROR: 1222 - SQLSTATE: HYT00 - Execute failed:  Lock request time out period exceeded. on line 9461 in Quote Entry - Payable, Accounts
01/31/2014 14:07:11 USERD <25000> ERROR: 1222 - SQLSTATE: HYT00 - Execute failed:  Lock request time out period exceeded. on line 324491 in &Orders on object SELECT_ORD_BTN.
01/31/2014 15:49:34 USERG <25000> ERROR: 50000 - SQLSTATE: 42000 - Execute failed:  \n\nNo Lines entered. Must finish entering lines. on line 281522 in Quote Entry - Payable, Accounts
01/31/2014 15:51:01 USERH <25000> ERROR: 50000 - SQLSTATE: 42000 - Execute failed:  \n\nNo Lines entered. Must finish entering lines. on line 281522 in Quote Entry - Payable, Accounts
I'm having issues breaking these lines into its components. Ideally, I'd like to create an output CSV file that breaks the components of these lines thus:
DATE, TIME, USER, ERROR, ERRORID, MESSAGE
Following on the method I mentioned above, I was planning to pipe the output into a foreach and perhaps use regex to extract the parts of the line, but I'm having difficulties. I have the regex figured out, and I have tried combining them with the -split
operator and the select-string, but I'm not having much luck.
What is the best method to process these lines so I can split them at specific locations in the string?
Using one of the example outputs above, I need to split the line in the following spots (note the commas)
01/31/2014, 15:51:01, USERH, <25000> ERROR:, 50000 - SQLSTATE:, 42000 - Execute failed:  \n\nNo Lines entered. Must finish entering lines. on line 281522 in Quote Entry - Payable, Accounts

Answer 1

Well, I ended up using
$mydate=$line.split(" ")[0]
$myTime=$line.split(" ")[1]
... etc
to extract the first 6 fields in the line as they're all (more or less consistently) separated by spaces. For the final (message) field, I used your recommendation above.
I redistributed the fields so they'd split at the spaces and I concatenated 
01/31/2014 | 15:51:01 | USERH | <25000> | ERROR: 50000 - | SQLSTATE: 42000 - | Execute failed:  \n\nNo Lines entered. Must finish entering lines. on line 281522 in Quote Entry - Payable, Accounts.
Thanks for pointing me in the right direction.
