Question

 INSERT INTO TextTable(Number, Tokens)  
 SELECT 
 (SELECT  ID FROM  Tureme WHERE leksem IN  
 (SELECT  Tokens FROM  Text)),
 (SELECT  Tokens FROM Text WHERE Tokens IN 
 (SELECT  leksem FROM Tureme));

TextTable has two columns-> Number,Tokens
Tureme has two columns -> ID(Primary Key), leksem
and
Text has one column -> Tokens

My tables:

TextTable is empty.

What I’m trying to do is inserting the results of these subqueries into TextTable. The subqueries works perfect individually. But, when I run it together, it doesn’t insert results of subqueries and it gives an error saying:

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated.

What should i do?

---

First subquery returns:                        Second subquery returns:

ID                                                            Tokens

4                              apple
6                              melon
9                              pear

I want to populate TextTable with these values.

Answer 1

INSERT INTO TextTable
SELECT DISTINCT ID, Text.Tokens
FROM Tureme
JOIN Text ON Tureme.leksem = Text.Tokens

I guess this is exactly what you want.
