What is BCP format file?

The bulk copy program utility (bcp) bulk copies data between an instance of Microsoft SQL Server and a data file in a user-specified format. The bcp utility can be used to import large numbers of new rows into SQL Server tables or to export data out of tables into data files.

How do you ignore inserts?

Use the INSERT IGNORE command rather than the INSERT command. If a record doesn’t duplicate an existing record, then MySQL inserts it as usual. If the record is a duplicate, then the IGNORE keyword tells MySQL to discard it silently without generating an error.

How does insert ignore work?

Insert Ignore statement in MySQL has a special feature that ignores the invalid rows whenever we are inserting single or multiple rows into a table. We can understand it with the following explanation, where a table contains a primary key column. The primary key column cannot stores duplicate values into a table.

How do I specify rows terminator in BCP?

To place each data record on its own line in the data file, specify the combination \r\n as the row terminator. When you use bcp interactively and specify \n (newline) as the row terminator, bcp automatically prefixes it with a \r (carriage return) character, which results in a row terminator of \r\n.

Why does it skip rows in a BCP file?

It doesn’t skip “rows” in the classic sense. Instead, it skips “delimiter sets” as defined in the “format lines” of the BCP Format File. The reason why they did this is so that you could import multi-line rows as a single record (an easy thing to do with a BCP Format File).

Can BCP-F and-L switches skip header and footers?

This is working for tab delimited files but not for fixed length files because the header row is just of 10 to 20 characters where as the detail record spans for few hundred lines. Doing some research lead me to the conclusion that -F and-L switches in bcp are not intended to skip header and footers as it looks at the field terminators.

What is the last column of the BCP format file for?

The last column of the BCP Format File is for “Collation Name “. Two double quotes should be used for any non-character based columns in the table. For character based columns, you could include the collation name for the particular column if it’s other than the server default.

How do I change the default format of a BCP file?

In both cases, there are two steps: Use the bcp command-line utility to create a default format file. Modify the default format file in a text editor. The modified format file must map each existing field to its corresponding column in the destination table. It must also indicate which table column or columns to skip.
