‘abc’ || ‘xyz’, when PIPES_AS_CONCAT is enabled, results in ____________(a) 0(b) 1(c) abcxyz(d) xyzabc |
|
Answer» Right option is (c) abcxyz To explain I would say: If the SQL mode PIPES_AS_CONCAT has been enabled, the SQL standard ‘||’ operation for string concatenation becomes valid in MySQL. Both operands are concatenated to give ‘abcxyz’. |
