问题 So the problem goes like this: I have a table with two columns namely source query and target query. each row contains a sql query for a informatica mapping from source side and target side and we needed to build a reconciliation procedure which take those two values for each row and generate there output and store it in temp table say temp1 and temp2 and then compare the result of these two temp tables. I Did this by creating two tables and then bulk fetching through two cursors and

问题 I'm having problems with creating this trigger in PostgreSQL 8.4.

问题 Is it possible to dynamically access a column value from a record by its name? I'm writing a trigger function that executes a dynamic SQL command and I would like to dynamically extract a column value from a NEW record by column name. Here's a simplified example of what I'm trying to do: $$ DECLARE command text := 'UPDATE $1 SET $2 = $3'; myColumn := 'votes' BEGIN EXECUTE command using 'anotherTable', myColumn, NEW.myColumn; END $$ 回答1: That's possible , but the USING clause of EXECUTE can

问题 Ok so, I've been ripping my hairs ou on this one, why doesn't this work? DELIMITER | CREATE PROCEDURE Decrypt_pw() READS SQL DATA BEGIN SELECT 'Hey Select'; END| It's so basic and I'm pretty sure I'm using the correct syntax, what am I missing?

That's why you don't get the second message. val1 will have the same value as before the select - i.e. null if you

问题 I have kind of a tricky Oracle problem. I am trying to select one set of data, we'll call items. For each item I want to call another procedure and return an Inventory Item. I have two operations I am not sure on how to perform. How do I retrieve a value from the nested procedure? How do I return those retrieved values in the form of SYS_REFCURSOR? My attempt here was to put the results from spSelect_Inv_Search into a nested table called ITEMS_TABLE. This is not working. Code below PROCEDURE

问题 Good afternoon. How do I get Oracle, see what procedures are running? 回答1: Depending on your needs, this might suffice (but relies on access to v$session and dba_objects): select 'CALLED PLSQL', vs.username, d_o.object_name -- whatever info you need from dba_objects d_o inner join v$session vs on d_o.object_id = vs.plsql_entry_object_id union all select 'CURRENT PLSQL', vs.username, d_o.object_name from dba_objects d_o inner join v$session vs on d_o.object_id = vs.plsql_object_id As per the
