ERROR: No results. Previous SQL was not a query.
so please help me out to clear this error.
>Solution :
change the line of code to as below
b = 'alter table temp1 add column3 varchar(10);'
this assigns the entire SQL command as string to the variable b, which then you can use in the call to execute() function of the cursor.
Also, the ALTER TABLE SQL statement will not return any results set, so you need not call fetchXX() method after executing it.
