SQL Server Insert Command Error - sql-server

Question

INSERT INTO BORCODEME
( BORCODEME.IslemTarihi, BORCODEME.IslemAciklamasi,BORCODEME.IslemTutari)
VALUES(
(SELECT BORCLAR.BorcTarih,BORCLAR.BorcAciklama,BORCLAR.BorcTutari FROM BORCLAR WHERE BORCLAR.BorcMusteriID=6),
(SELECT ODEMELER.OdemeTarihi,ODEMELER.OdemeAciklama,ODEMELER.OdemeTutar FROM ODEMELER WHERE ODEMELER.OdemeMusteriID=6)
)
My SQL command is this, and I have these errors;
Msg 116, Level 16, State 1, Line 4
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
Msg 116, Level 16, State 1, Line 6
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
Msg 109, Level 15, State 1, Line 1
There are more columns in the INSERT statement than values specified in the VALUES clause. The number of values in the VALUES clause must match the number of columns specified in the INSERT statement.

Answer 1

Not sure what you're really looking for - are you trying to insert the three columns from the two tables? Then write your INSERT like this:
INSERT INTO BORCODEME(IslemTarihi, IslemAciklamasi, IslemTutari)
SELECT
BORCLAR.BorcTarih, BORCLAR.BorcAciklama, BORCLAR.BorcTutari
FROM
BORCLAR
WHERE
BORCLAR.BorcMusteriID = 6
UNION
SELECT
ODEMELER.OdemeTarihi, ODEMELER.OdemeAciklama, ODEMELER.OdemeTutar
FROM
ODEMELER
WHERE
ODEMELER.OdemeMusteriID = 6
So this will insert the three values from BORCLAR and another row with the three values from ODEMELER.
If that's not what you want, then you need to explain in more detail what you really want instead.....
In general, you can either use this syntax:
INSERT INTO dbo.TargetTable (List-of-Columns)
VALUES (List-of-atomic-values)
or if you cannot provide atomic values (literals or T-SQL variables), then you can use
INSERT INTO dbo.TargetTable (List-of-Columns)
SELECT list-of-columns
FROM dbo.SourceTable
(but you cannot mix - you cannot have VALUES and then use SELECT inside of it)
In both cases, the number of columns in the INSERT statement must match exactly with the number of atomic values provided in VALUES or the number of columns selected by the SELECT statement
