Re: The DROP TABLE instruction should have a TEMP option for when a temporary table

Hi Tom,

Thanks a lot, for the response!

Yes, you are right, there is a secure way for drops, prefixing with the
schema name.
But, for this particular case, TEMPORARY tables, as a special way for
CREATE TABLE, It would be good to have also an special way for DROP TABLE.
(It is just an opinion)

Today I realized that,
and I've created my functions:

--/*
;CREATE FUNCTION "dailyDataProcessingEphemerals"."getTemporalSchemaName"()
RETURNS text
AS $$
SELECT quote_ident(nspname) FROM pg_namespace WHERE oid =
pg_my_temp_schema();
$$ LANGUAGE SQL;

-- RUN AS: ;SELECT * FROM
"dailyDataProcessingEphemerals"."getTemporalSchemaName"()

;CREATE FUNCTION
"dailyDataProcessingEphemerals"."dropTemporalTableIfExists"("tableName"
text)
RETURNS void
LANGUAGE "plpgsql"
AS $$
BEGIN
EXECUTE 'DROP TABLE IF EXISTS ' || (SELECT "getTemporalSchemaName" FROM
"dailyDataProcessingEphemerals"."getTemporalSchemaName"()) || '.' ||
quote_ident("tableName");
END $$
--*/

Regards Pablo
