SQL BULK INSERT - How to import a CSV file with Commas inside
Posted on 2012-04-07
I have to import a CSV file containing several million rows into SQL Server, in which one specific column contains a comma in some records. This comma is causing the import to split the field value into two pieces and move values into the wrong columns for those records.
When the file is opened in Notepad a record has this example form:
Value1,Value2,Value3,,Value5,Value6,"Flat1, High Street",Value8,,Value10
The problem is caused by the column containing "Flat1, High Street" due to the internal comma. I have no control over the format of the file as this comes from an external operating system and so have to deal with the file as it comes. I cannot import it first into Excel to perform manipulations as the file is several million rows.
Is there a way to perform the BULK INSERT into SQL, or to process the file first with some other tool? If it helps, I can rely on knowing that it is always the same column that may cause problems. Also, the problem values are always surrounded by "" as in the example above.
