Problem:
Insert large amount of data in text file to a SQL database
table with minimum time.
Solution:
Using ‘Bulk Insert’ is the solution.
I had to import large amount of data in text file to SQL
database. If I programmatically insert this data, it would take more time and
memory. Therefore, I use SQL bulk insert to import this data. If the fields in
the data files are separated using a special character (comma – ‘,’) they can
be directly insert in to columns in the database with one query. In addition,
it can be fields are not separated, but have known lengths. Then you have to
substring them according to lengths.
