SQL插入命令歧义

Question

I'm trying to use a sql command like this but it's not working for some obvious reasons.Can you tell me what's the way out for this type of commands ?

   INSERT INTO ContentToGroup(ContentId,ClassSectionId)  
   VALUES (16, Select ClassSectionId from ClassSectionMaster where ClassId=1)

Answer 1

INSERT INTO ContentToGroup (ContentId,ClassSectionId)
Select 16, ClassSectionId
from ClassSectionMaster
where classid = 1

Answer 2

You cannot mix the INSERT .... VALUES.... with "inline" select statements. Using the VALUES keyword, you must provide all values as literals or SQL variables.

Either you need to select the value first and assign it to a variable:

DECLARE @ClassSectionID INT

SELECT @ClassSectionID = ClassSectionID 
FROM dbo.ClassSectionMaster WHERE ClassId = 1

INSERT INTO ContentToGroup(ContentId,ClassSectionId)  
VALUES (16, @ClassSectionID)

or then use the SELECT statement others have shown to provide all values (and then you omit the VALUES keyword)

Answer 3

INSERT INTO ContentToGroup(ContentId,ClassSectionId) Select 16, ClassSectionId from ClassSectionMaster where ClassId=1

Answer 4

First you need to remove the VALUES when you are using an nested query. Also try specifying the table names in front of the field name in case that is causing your ambiguity.

INSERT INTO ContentToGroup(ContentId,ClassSectionId) 
    SELECT 16, ClassSectionMaster.ClassSectionId 
    FROM ClassSectionMaster 
    WHERE ClassSectionMaster.ClassId=1
