In Oracle/PLSQL, the numtodsinterval function converts a number to an INTERVAL DAY TO SECOND literal.
The syntax for the numtodsinterval function is:
numtodsinterval( number, expression )
number is the number to convert to an interval.
expression is the unit. It must be one of the following values: DAY, HOUR, MINUTE, or SECOND.
For example:
numtodsinterval(150, 'DAY') would return '+000000150' numtodsinterval(1500, 'HOUR') would return '+000000062' numtodsinterval(15000, 'MINUTE') would return '+000000010' numtodsinterval(150000, 'SECOND') would return '+000000001'
