I’m trying to efficiently import millions of records from a fixed-width text file into SQL Server 2000. My specific challenge is managing the data import process when some records contain invalid date formats.
Requirements
- Need a method to process large batches of records
- Want to automatically redirect problematic records
- Prefer solution without SSIS installation
- Maintain overall batch processing continuity
Currently considering BCP (Bulk Copy Program), but need a robust approach to handle potential data validation errors during the import.
hey, cool problem! wht abt using a custom python script to validate n filter ur records b4 bulk import? u could easyly seprate valid/invalid data n log errors. wanna hear more bout ur specific file structure?
u cud try writing a quick powershell script 2 clean ur data b4 import. separates bad rows n logs em. way easier than manual bcp method. might save u tons of headache w/ ur massive txt file. quick n dirty solution ftw!
For your specific scenario with SQL Server 2000, I recommend creating a custom preprocessing script that handles data validation before bulk import. Since BCP has limitations with error management, you'll want a two-stage approach: first validate and filter your data, then perform the bulk import.
A pragmatic solution would involve writing a short script in VBScript or a similar language compatible with older Windows environments. The script would read your fixed-width text file, parse each record, validate date formats, and create two output files - one for valid records and another for problematic entries. You can then use BCP to import the clean dataset while separately logging invalid records for manual review.
Key steps include implementing robust date parsing logic, tracking error types, and ensuring minimal performance overhead during data processing. This method provides a flexible, low-overhead solution that meets your requirements of batch processing, error redirection, and avoiding SSIS installation.
nice challenge! u cud try regex parsing in ur preprocessing script 2 catch those funky date formats. would help u clean data b4 bcp import. got any sample records u can share 4 more specific advice? lemme knw how it goes!
yo, quick hack for ur sql server prob! try regex w/ vbscript 2 catch weird date formats. split valid/invalid data b4 bcp import. u’ll save urself major headache w/ big txt files. lemme knw if u need more detailz!
