Combinations of SQL Operators

Multiple operators can also be combined, as in the following examples:

field1 POSITION(*+3) INTEGER EXTERNAL
       "TRUNC(RPAD(:field1,6,'0'), -2)"
field1 POSITION(1:8) INTEGER EXTERNAL
       "TRANSLATE(RTRIM(:field1),'N/A', '0')"
field1 CHAR(10)
       "NVL( LTRIM(RTRIM(:field1)), 'unknown' )"
