Updating tables within cursor loop dating a colt trooper mkiii

WHILE flag1 ' END' THEN SET concat_description = CONCAT(dept_id,'*',major_description); INSERT INTO messages VALUES (concat_description); END IF; END WHILE; -- free memory CLOSE get Majors From Each Dept; SET flag1 = flag2; END IF; END WHILE;-- Loop end.-- free memory CLOSE get Dept;--- Display all records of Messages Table---------SELECT * FROM messages; END;//DELIMITER ; Purvi Just as a response to that last comment, wouldn't it be easier just to do this?CREATE PROCEDURE get_major_info_for_all_dept()INSERT INTO messages SELECT CONCAT(dept.deptid, '*', major.description)FROM dept JOIN major ON dept.deptid = major.dept_id Are you looking for an alternative cursor traversal code template in which there is no loop control variable (like "done") and no label (like "My Label:") ? id=186 This method is stored function safe, even when nested into each other.

I worry about how ETL tools apply updates (did you know Data Stage applys updates singly, but batches inserts in arrays? The two most common forms of Bulk Updates are: Case 1 is uninteresting. I spend an inordinate proportion of design time of an ETL system worrying about the relative proportion of rows inserted vs updated.Oracle provides the FOR UPDATE clause in SQL syntax to allow the developer to lock a set of Oracle rows for the duration of a transaction.The syntax of using the WHERE CURRENT OF clause in UPDATE and DELETE statements follows: WHERE [CURRENT OF cursor_name | search_condition] The following example opens a cursor for employees and updates the commission, if there is no commission assigned based on the salary level.We must declare the cursor with the FOR UPDATE clause to use this feature.

Inside a cursor loop, WHERE CURRENT OF allows the current row to be directly updated.The solution I found is somewhat cumbersome (but works!) - I've redeclared the HANDLER in each of the functions :/* Disable DATA NOT FOUND handlers from calling functions */DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' BEGIN END; There are really helpful comments posted here and throughout the manual.DECLARE this Student Student%ROWTYPE; CURSOR Maths_Student IS SELECT * FROM Student WHERE SID IN (SELECT SID FROM Take WHERE CID = ’CS145’) FOR UPDATE; BEGIN OPEN Maths_Student; LOOP FETCH Maths_Student INTO this Student; EXIT WHEN (Maths_Student%NOTFOUND); IF (this Student.PDF (US Ltr) - 37.4Mb PDF (A4) - 37.4Mb PDF (RPM) - 36.9Mb EPUB - 10.6Mb HTML Download (TGZ) - 10.3Mb HTML Download (Zip) - 10.4Mb HTML Download (RPM) - 9.0Mb Eclipse Doc Plugin (TGZ) - 11.2Mb Eclipse Doc Plugin (Zip) - 13.4Mb Man Pages (TGZ) - 204.7Kb Man Pages (Zip) - 311.7Kb Info (Gzip) - 3.4Mb Info (Zip) - 3.4Mb My SQL Backup and Recovery My SQL Globalization My SQL Information Schema My SQL Installation Guide My SQL and Linux/Unix My SQL and OS X My SQL Partitioning My SQL Performance Schema My SQL Replication Using the My SQL Yum Repository My SQL Restrictions and Limitations Security in My SQL My SQL and Solaris Building My SQL from Source Starting and Stopping My SQL My SQL Tutorial My SQL and Windows My SQL NDB Cluster 7.5 CREATE PROCEDURE curdemo() BEGIN DECLARE done INT DEFAULT FALSE; DECLARE a CHAR(16); DECLARE b, c INT; DECLARE cur1 CURSOR FOR SELECT id,data FROM test.t1; DECLARE cur2 CURSOR FOR SELECT i FROM test.t2; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE; OPEN cur1; OPEN cur2; read_loop: LOOP FETCH cur1 INTO a, b; FETCH cur2 INTO c; IF done THEN LEAVE read_loop; END IF; IF b PDF (US Ltr) - 37.4Mb PDF (A4) - 37.4Mb PDF (RPM) - 36.9Mb EPUB - 10.6Mb HTML Download (TGZ) - 10.3Mb HTML Download (Zip) - 10.4Mb HTML Download (RPM) - 9.0Mb Eclipse Doc Plugin (TGZ) - 11.2Mb Eclipse Doc Plugin (Zip) - 13.4Mb Man Pages (TGZ) - 204.7Kb Man Pages (Zip) - 311.7Kb Info (Gzip) - 3.4Mb Info (Zip) - 3.4Mb My SQL Backup and Recovery My SQL Globalization My SQL Information Schema My SQL Installation Guide My SQL and Linux/Unix My SQL and OS X My SQL Partitioning My SQL Performance Schema My SQL Replication Using the My SQL Yum Repository My SQL Restrictions and Limitations Security in My SQL My SQL and Solaris Building My SQL from Source Starting and Stopping My SQL My SQL Tutorial My SQL and Windows My SQL NDB Cluster 7.5 Hi all, as beat pointed out, LOOP is the only construct that I found useful for traversing cursors. See examples: Nesting cursors is possible, you just need to take care of a few things.The FOR UPDATE clause in the SELECT statement can only be specified in the top level; subqueries cannot have this clause.
