Data migration in a database management system
Abstract:
An approach is provided to copy records between tables in a relational database. In the approach, a Structured Query Language (SQL) table COPY statement is received with the COPY statement identifying a source table and a target table. Table column names are retrieved from a metadata that corresponds to the source table. The retrieved table column names are used to generate an SQL statement that includes an INSERT INTO clause pertaining to the target table and a SELECT clause pertaining to the source table, wherein the INSERT INTO clause includes a set of target column names and wherein the SELECT clause includes a set of corresponding source column names.
