I have two categories, say A and B. Each of the category includes many entries. I want to merge them into one category, say A. How can i do (with moodle codes or mysql) so that I don't need to to them manually (by changing each entry).

Thank you very much

Dear Giang,

There is unfortunately no direct method through the Moodle interface to bulk move glossary entries from one category to another. However, if you have access to your Moode site database, through phpMyAdmin, here's a little example illustrating how to do it.

Suppose in your Moodle course you have 2 glossaries: "Giang's glossary" and "Joseph's glossary". in "Giang's glossary" we have created 2 categories named Category A and Category B. in "Joseph's glossary" we have created 2 categories named Category C and Category D. Enter your Moodle mysql database using phpMyAdmin.

go to Table mdl_glossary to identify the id number of Giang's glosary, (extract below)

Id course name
2 2 Giang's glossary
3 2 Joseph's Glossary

In course id 2 we have Giangg's glossary id 2 and Joseph's glossary id 3

go to Table mdl_glossary_categories

identify the categories id

Id

glossaryid

name

usedynalink

4

2

category A

0

5

2

category B

0

6

3

category C

0

7

3

category D

0

In Giang's glossary (id 2) we have category A, id 4 and category B, id 5.

we want to move all glossary entries from category B (id 5) to category A (id 4).

In the sql query window, we type this command:

UPDATE `mdl_glossary_entries_categories` SET `categoryid` = '4' WHERE `categoryid` = '5';

or (without the queer apostrophes):

UPDATE mdl_glossary_entries_categories SET categoryid = '4' WHERE categoryid = '5';
