Use Destination to indicate the database table that will be created or altered by the batch operation. The batch operation affects the Destination differently depending on the Mode: 

Mode Effect on Destination 

• batAppend Records are added to the destination table. No pre-existing records are altered. The destination table must already exist.
• batUpdate Records in the destination table with key fields matching the corresponding fields in the source are changed to match the source records. No new records are added. The destination table must already exist and must have an index defined.
• batAppendUpdate Records in the destination table with key fields matching the corresponding fields in the source are changed to match the source. Source records that do not match key fields are added to the destination table. The destination table must already exist and must have an index defined.
• batDelete Records in the destination table that match the records in the source are deleted. The destination table must already exist and must have an index defined.
• batCopy The destination table is created to match the records in the source. If Destination already exists, it is replaced by the copy of the source.
