Greetings,
I have a plpython function that returns a set of records. I loop over
them to insert them into a temp table created by another function.
I wanted to test
select into temp_eav_table (column) select a.column from tbl as a where....
approach to see if it performs better than the loop. However, I'm not
able to compile the function due to an error that says "temp_eav_table
is not a known variable"
Probably going to have to show the actual plpython code. The message
looks like you used temp_eav_table as a variable before defining it.
So the context assumes this is supposed to be a variable. If I try
execute '...', then I have trouble passing a bytea parameter to the
python function. This is what I have at the moment:
SELECT INTO temp_eav_table (valstring,
featuremappingid,
featurename,
rmtypename,
actualrmtypename,
path,
pathstring)
select selected_node.valstring,
selected_node.featuremappingid,
selected_node.featurename,
selected_node.rmtypename,
selected_node.actualrmtypename,
selected_node.path,
selected_node.pathstring
from py_get_eav_rows_from_pb(payload ) as selected_node;
any thoughts?
I think you may be reading the plpgsql docs. The SELECT INTO syntax
there only exists within plpgsql. You are using plpythonu and it will
not work there. It follows the syntax here:
