8. A computer program product for a database storage reclaiming program, the computer program product comprising: one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising: program instructions to retrieve a list of data elements for deletion from a database catalog, wherein the list of data elements for deletion details one or more data elements contained in a database; program instructions to determine whether first data elements of the one or more data elements on the list of data elements for deletion have been active in one or more static Structured Query Language (SQL) statements, wherein the one or more SQL statements are persistent and created before runtime; program instructions to remove the first data elements of the one or more data elements from the list of data elements for deletion that have been determined to be active in the one or more static SQL statements; program instructions to determine whether second data elements of the one or more data elements on the list of data elements for deletion have been active in one or more dynamic SQL statements, wherein the one or more dynamic SQL statements are non-persistent and created at runtime; program instructions to remove the second data elements of the one or more data elements from the list of data elements for deletion that have been determined to be active in the one or more dynamic SQL statements; program instructions to determine whether third data elements of the one or more data elements on the list of data elements for deletion are associated with one or more data elements not on the list of data elements for deletion; program instructions to remove the third data elements of the one or more data elements from the list of data elements for deletion that are determined to be associated with the one or more data elements not on the list of data elements for deletion; program instructions to determine whether fourth data elements of the one or more data elements on the list of data elements for deletion are used in a source code of one or more applications; and program instructions to remove the fourth data elements of the one or more data elements from the list of data elements for deletion that are determined to be used in the source code of the one or more applications.
13. The computer program product of claim 8 , wherein the determining whether the fourth data elements of the one or more data elements on the list of data elements for deletion are used in the source code of the one or more applications includes analyzing one or more application source codes and workload logic in order to extract the one or more SQL statements and cross reference the extracted one or more SQL statements with the one or more data elements on the list of data elements for deletion.
