Hi,
in my plpgsql function I'm looping through tables and their fields and i want to return their field names and the corresponding values.
It all works fine, except i can't retrieve the values, which is really a bummer.
I tried a couple of things (in vain), of which this seemed the most promising:
<<records>>
FOR t_record IN EXECUTE
t_qstring
LOOP
<<fields>>
FOR t_i IN 1..array_upper(t_fields, 1)
LOOP
t_rec_out.field_name := t_fields[t_i];
--retrieve the value of this column, this record, this table into "field_value" for return.
t_qstring := 't_record.'||t_fields[t_i]; --re-using t_qstring!
EXECUTE t_qstring INTO t_rec_out.field_value; --<==== happens here ===
RETURN NEXT t_rec_out;
On EXECUTE, i get the error:
ERROR: syntax error at or near "t_record"
I also tried:
<<records>>
FOR t_record IN EXECUTE
t_qstring
LOOP
<<fields>>
FOR t_i IN 1..array_upper(t_fields, 1)
LOOP
t_rec_out.field_name := t_fields[t_i];
--retrieve the value of this column, this record, this table into "field_value" for return.
t_rec_out.field_value := t_record.t_fields[t_i]; --<==== happens here ===
RETURN NEXT t_rec_out;
And then i get the error:
ERROR: record "t_record" has no field "t_fields"
Any tips there?
Cheers,
WBL
