Set connection data
When a record is stored, UDS/SQL automatically adds set connection data (SCD) if the
record has to be connected with other records or tables. table 20 shows what the SCD
consists of in each case.
The length of the SCD may vary, depending on which page length was defined for the
database. The effect of the database page length on that of the SCD is indicated in table 20
in the column “SCD length in bytes” by means of 2 values (e.g. 8/12):
– The first value shows the SCD length for databases with a page length of 2048 bytes.
– The second value shows the SCD length for databases with a page length of 4000 or
8096 bytes.
