Insert a concatenated string from one table into a field in another

Question

See more:

Table 1 (Course) has the following fields:

course.name (for example, Science)
course.number (for example, SC101S1)
course.id
course.calendarid

Table 2 (CustomCourse) has the following following fields:
customcourse.id
customcourse.value
customcourse.attributeid

I want to insert into customcourse.value the concatenated value of course.name + '-' + course.number from the course table

What I have tried:

I've tried an update statement but 0 rows are affected:

--Works but zero rows affected
UPDATE customcourse SET customcourse.value = name + '_' + number
from course
Inner join customcourse on customcourse.courseID = course.courseID
where course.calendarID = '162'
and course.number = 'CL03S2'
and customcourse.attributeID = '1132'

--Syntax doesn't work in INSERT INTO statement

INSERT INTO CustomCourse
Select Concat ('course.name', '_', 'course.number') AS customcourse.value
Inner join course on course.courseID = customccourse.courseID
where customcourse.attributeID = '1132'
and course.calendarID = '162'

Solution 1

Assuming customcourse.id is an IDENTITY field:

SQL

INSERT INTO customcourse
(
    value,
    attributeid
)
SELECT
    Concat(course.name, '_', course.number),
    '1132'
FROM
    course
WHERE
    calendarID = '162'
;
