I have a table with a varchar column.
I want to select the distinct values from this column and loop through
them (using as a variable) in a raise notice statement and also in an
update statement.
I have not been able to do this trying over 100 things in the last two
hours. I could not find an example on google.
for tmp_var in select distinct(value) from mytable where
value2='literal'
loop
raise notice 'I want to print a message here - the tmp_var is
[' || tmp_var || ']';
update table set varcharid = ''' || tmp_var || '''
end loop;
tmp_var has to be in ' ' ticks or will not work. it is failing on the
first FOR statment stating: "invalid input syntax for integer:
"some_distinct_value".
How do I select varchar distinct values and iterate using variables in a
raise notice statement and inside another update statement?
this seems simple to do , but have not found a way.
