procedure

问题 I'm trying to extract Stored procedure DDL by querying system tables. If I run the following query select * from dbc.tvm where TableKind = 'P' both fields RequestText and CreateText contain NULL. Is there any way to query Stored Procedure body apart from using SHOW PROCEDURE? Thank you. 回答1: The DDL (SPL) for the Stored Procedures is not stored in the data dictionary tables. If you do not retain your DDL in a repository for version control you will need to script the SHOW PROCEDURE commands

问题 Suppose you already have the basic binary tree procedures isempty(bt), root(bt), left(bt), and right(bt). Write a procedure isLeaf(bt) that returns true if the binary tree bt is a leaf node and false if it is not. This is what I have: proc isLeaf(bt) if (isEmpty(bt)) error('The binary tree is empty.'); elseif (left(bt) < right(bt)) return true; else return false; Then write a procedure numLeaves(bt) that returns the number of leaves in the binary tree bt. This is what I have: proc numLeaves

问题 I am trying to write a procedure with the following functionality. Namely, is looking for records from the tables in the schema. In particular, it is a typepkstring column in these tables. At the same time, I have the composedtypes table on the same schema, which has the column pk. The pk column contains all number identifiers from the aforementioned typepkstring column. And now the problem is that in typepkstring we have additionally keys that are not in the column pk in tabel composedtypes.
