Employee photo and resume table (DSN8C10.EMP_PHOTO_RESUME)

The sample employee photo and resume table complements the employee table.

Begin general-use programming interface information. Each row of the photo and resume table contains a photo of the employee, in two formats, and the employee's resume. The photo and resume table resides in table space DSN8D12L.DSN8S12B. The following statement creates the table:

CREATE TABLE  DSN8C10.EMP_PHOTO_RESUME
               (EMPNO      CHAR(06) NOT NULL,
                EMP_ROWID  ROWID NOT NULL GENERATED ALWAYS,
                PSEG_PHOTO BLOB(500K),
                BMP_PHOTO  BLOB(100K),
                RESUME        CLOB(5K),
                PRIMARY KEY  (EMPNO))
        IN  DSN8D12L.DSN8S12B
        CCSID  EBCDIC;

Db2 requires an auxiliary table for each LOB column in a table. The following statements define the auxiliary tables for the three LOB columns in DSN8C10.EMP_PHOTO_RESUME:

CREATE AUX TABLE DSN8C10.AUX_BMP_PHOTO
               IN DSN8D12L.DSN8S12M
               STORES DSN8C10.EMP_PHOTO_RESUME
               COLUMN BMP_PHOTO;
 
CREATE AUX TABLE DSN8C10.AUX_PSEG_PHOTO
               IN DSN8D12L.DSN8S12L
               STORES DSN8C10.EMP_PHOTO_RESUME
               COLUMN PSEG_PHOTO;
 
CREATE AUX TABLE DSN8C10.AUX_EMP_RESUME
               IN DSN8D12L.DSN8S12N
               STORES DSN8C10.EMP_PHOTO_RESUME
               COLUMN RESUME;

End general-use programming interface information.
