Method and a system for merging data into a database table

The present invention relates to a method and a system for importing data into a database table with constraints consistency analysis and customized merge parameters. The method includes providing the table with data identities and a primary key assigned to each of the data identities. A temporary copy of the table is generated and contains at least one data identity to be merged into the table. The table structure of the table and the table structure of the temporary copy are determined. A temporary copy of a new column is created and contains a final primary key of the related data identity for its transfer into the table, thereby assigning the same primary key to the data identity in the temporary copy if the data exists already in the table. A new primary key is assigned to the data identity in the temporary copy if the data identity is not present yet in the table. The data identities in the table that are present in the temporary copy are locked and an update function for the data identities having the same primary key in both the table and the temporary copy are executed. An import function for the data identities having a newly assigned primary key comprised in the new column of the temporary copy is also executed. The locked data identities are unlocked after the successful execution of the updating and the importing function.
