Setting bulk insert options


Data file type

Use this drop-down list to select the data file type value to be used to perform the load operation. Possible data file type values are: char, native, widechar and widenative.

 

Batch size (rows)

Specify the number of rows in a batch. Each batch is copied to the server as one transaction. If this operation fails, SQL Server commits or rolls back the transaction for every batch.

 

Kilobytes per batch

Specify the approximate number of kilobytes (KB) of data in each batch.

 

Rows per batch

This value indicates the number of rows in each batch.

 

Bulk Insert - Setting bulk insert options

 

 

CheckBox Check constraints

Enable this option to specify that all constraints on the target table or view must be checked during the bulk insert operation. If disabled, any CHECK constraints are ignored, and after the operation the constraint on the table is marked as not-trusted. This might be necessary if the input data contains rows that violate constraints.

Note: UNIQUE, PRIMARY KEY, FOREIGN KEY and NOT NULL constraints are always enforced.

 

CheckBox Fire triggers

Use this option to specify that any insert triggers defined on the destination table execute during the bulk load operation. If triggers are defined for INSERT operations on the target table, they are fired for every completed batch.

 

CheckBox Keep identity

Use this option to specify that identity value or values in the imported data file are to be used for the identity column. If this option is not checked, the identity values for this column are verified but not imported, and SQL Server automatically assigns unique values based on the seed and increment values specified during table creation.

 

CheckBox Keep nulls

Use this option to specify that empty columns should retain a null value during the bulk load operation, instead of having any default values for the columns inserted.

 

CheckBox Table lock

Use this option to specify that a table-level lock is acquired for the duration of the bulk load operation. Holding a lock for the duration of the bulk load operation reduces lock contention on the table and may significantly improve performance.

 

 

Max errors

Specifies the maximum number of syntax errors allowed in the data before the bulk insert operation is canceled. Each row that cannot be imported by the bulk load operation is ignored and counted as one error.

Note: This option is not applied to constraint checks and to converting money and bigint data types.

 

Error file

Specify the file used to collect rows that have formatting errors and cannot be converted to an OLEDB rowset. These rows are copied into this error file from the data file "as is". The error file is created when the command is executed.
