插入另一个表中的值

Question

I am trying to insert into a field using the input from another table field. Although this is entirely feasible for many database engine,

I have the following fields,

New Table Schema

• Name
• Industryid(int)
• Locationid(int)

But the actual records like,

• xxxx
• TEXT (varchar)
• TEXT(Varchar)

But I want these two Industryid and Locationid by id's from another table Industries, Locations.

I have another 2 tables for

Industries

• Id
• Name

Locations

• Id
• Name

My Query is,

select'insert into organizations(name,industryid,locationid)
values
('''+
Nameofthecompany+''','+
Isnull(industrytype,'Null')+','+
ISNULL(Location,'Null')+')' 
from Organization`

Result

insert into organizations(name,industryid,locationid) 
values 
('Swamy',Telcom,Chennai)

Expected Result

insert into organizations(name,industryid,locationid)
values
('Swamy',12,150)

Answer 1

If your current/actual records are already in a table named Organization as shown in your query, you can use this approach to populate your new Organizations table:

INSERT INTO Organizations( name, IndustryId, LocationId )
SELECT o.Nameofthecompany, i.Id, l.Id
FROM Organization AS o
LEFT JOIN Industries AS i ON o.industrytype = i.Name
LEFT JOIN Location AS l ON o.Location = l.Name

This takes the existing names, joins to your reference tables ( Industries and Locations ) and retrieves the Id values for the corresponding text values.

The LEFT JOIN will bring back all of the names from Organization, but not require them to have a matching Industry and Location in the reference tables.

Answer 2

You can do something like this:

SELECT Col1, Col2
INTO TestTable
FROM OriginalTable
WHERE Conditions

Notice that SELECT INTO only works if the table specified in the INTO clause does not exist

Or:

INSERT INTO TestTable (Col1, Col2)
SELECT Col1, Col2
FROM OriginalTable
WHERE Conditions
