Can any one please let me know that, I need to add a column dynamically when executing mysql query
Table: Table1
--------------------------
col1 col2 col3
--------------------------
Test OK Test3
Test OK Test5
Test OK Test6
from the above example i need to introduce “col2” as new column and its value to be as “OK”
select a constant value and give it an alias.
but why do you need to do this in mysql? if the value is the same for every row, you can just as easy add it in your client (php or similar) code
