How can I delete using INNER JOIN with SQL Server?

You need to specify what table you are deleting from. Here is a version with an alias:

DELETE w
FROM WorkRecord2 w
INNER JOIN Employee e
  ON EmployeeRun=EmployeeNo
WHERE Company = '1' AND Date = '2013-05-06'

---

Just add the name of the table between DELETE and FROM from where you want to delete records, because we have to specify the table to delete. Also remove the ORDER BY clause because there is nothing to order while deleting records.

So your final query should be like this:

    DELETE WorkRecord2 
      FROM WorkRecord2 
INNER JOIN Employee 
        ON EmployeeRun=EmployeeNo
     WHERE Company = '1' 
       AND Date = '2013-05-06';

---

It is possible this will be helpful for you -

DELETE FROM dbo.WorkRecord2
WHERE EmployeeRun IN (
    SELECT e.EmployeeNo
    FROM dbo.Employee e
    WHERE ...
)

Or try this -

DELETE FROM dbo.WorkRecord2
WHERE EXISTS(
    SELECT 1
    FROM dbo.Employee e
    WHERE EmployeeRun = e.EmployeeNo
        AND ....
)

---

Try this:

DELETE FROM WorkRecord2 
       FROM Employee 
Where EmployeeRun=EmployeeNo
      And Company = '1' 
      AND Date = '2013-05-06'

---

It should be:

DELETE zpost 
FROM zpost 
INNER JOIN zcomment ON (zpost.zpostid = zcomment.zpostid)
WHERE zcomment.icomment = "first"

In SQL Server Management Studio I can easily create a SELECT query:

SELECT Contact.Naam_Contactpersoon, Bedrijf.BedrijfsNaam, Bedrijf.Adres, Bedrijf.Postcode
FROM Contact
INNER JOIN Bedrijf ON Bedrijf.IDBedrijf = Contact.IDbedrijf

I can execute it, and all my contacts are shown.

Now change the SELECT to a DELETE:

DELETE Contact
FROM Contact
INNER JOIN Bedrijf ON Bedrijf.IDBedrijf = Contact.IDbedrijf

All the records you saw in the SELECT statement will be removed.

You may even create a more difficult inner join with the same procedure, for example:

DELETE FROM Contact
INNER JOIN Bedrijf ON Bedrijf.IDBedrijf = Contact.IDbedrijf
INNER JOIN LoginBedrijf ON Bedrijf.IDLoginBedrijf = LoginBedrijf.IDLoginBedrijf

---

Try this query:

DELETE WorkRecord2, Employee 
FROM WorkRecord2 
INNER JOIN Employee ON (tbl_name.EmployeeRun=tbl_name.EmployeeNo)
WHERE tbl_name.Company = '1' 
AND tbl_name.Date = '2013-05-06';

Another way is using CTE:

;WITH cte
     AS (SELECT *
         FROM   workrecord2 w
         WHERE  EXISTS (SELECT 1
                        FROM   employee e
                        WHERE  employeerun = employeeno
                               AND company = '1'
                               AND date = '2013-05-06'))
DELETE FROM cte

Note: We cannot use JOIN inside CTE when you want to delete.

---

You could even do a sub-query. Like this code below:

DELETE FROM users WHERE id IN(
    SELECT user_id FROM Employee WHERE Company = '1' AND Date = '2013-05-06'
)

---

Here's what I currently use for deleting or even, updating:

DELETE           w
FROM             WorkRecord2   w,
                 Employee      e
WHERE            w.EmployeeRun = e.EmployeeNo
             AND w.Company = '1' 
             AND w.Date = '2013-05-06'

---

This is a simple query to delete the records from two table at a time.

DELETE table1.* ,
       table2.* 
FROM table1 
INNER JOIN table2 ON table1.id= table2.id where table1.id ='given_id'

---

You don't specify the tables for Company and Date, and you might want to fix that.

Standard SQL using MERGE:

MERGE WorkRecord2 T
   USING Employee S
      ON T.EmployeeRun = S.EmployeeNo
         AND Company = '1'
         AND Date = '2013-05-06'
WHEN MATCHED THEN DELETE;

The answer from Devart is also standard SQL, though incomplete. It should look more like this:

DELETE
  FROM WorkRecord2
  WHERE EXISTS ( SELECT *
                   FROM Employee S
                  WHERE S.EmployeeNo = WorkRecord2.EmployeeRun
                        AND Company = '1'
                        AND Date = '2013-05-06' );

The important thing to note about the above is it is clear the delete is targeting a single table, as enforced in the second example by requiring a scalar subquery.

For me, the various proprietary syntax answers are harder to read and understand. I guess the mindset for is best described in the answer by frans eilering, i.e. the person writing the code doesn't necessarily care about the person who will read and maintain the code.

Here is my SQL Server version

DECLARE @ProfileId table(Id bigint)

DELETE FROM AspNetUsers
OUTPUT deleted.ProfileId INTO @ProfileId
WHERE Email = @email

DELETE FROM UserProfiles    
WHERE Id = (Select Id FROM @ProfileId)

Delete multiple table data using transaction block, table variable and JOIN.

BEGIN TRANSACTION;

   declare @deletedIds table ( id int );
   
   DELETE w
   output deleted.EmployeeRun into @deletedIds
   FROM WorkRecord2 w
   INNER JOIN Employee e
           ON e.EmployeeNo = w.EmployeeRun
          AND w.Company = 1
          AND w.date = '2013-05-06';

   DELETE e
   FROM Employee as e
   INNER JOIN @deletedIds as d
           ON d.id = e.EmployeeNo;
COMMIT TRANSACTION;

Delete multiple table data with temporary table and JOIN. Drop temporary table after deletion.

BEGIN TRANSACTION;

    -- create temporary table
    create table #deletedRecords (employeeId int);
    
    -- INSERT INTO #deletedRecords
    SELECT e.EmployeeNo
    FROM WorkRecord2 w
    INNER JOIN Employee e
           ON e.EmployeeNo = w.EmployeeRun
          AND w.Company = 1
          AND w.date = '2013-05-06';
          
    -- delete from WorkRecord2
    DELETE w
    FROM WorkRecord2 w
    INNER JOIN #deletedRecords d
           ON w.EmployeeRun = d.employeeId;
           
    -- delete from Employee using exists
    DELETE 
    FROM Employee
    WHERE EXISTS (SELECT 1
                  FROM #deletedRecords d
                  WHERE d.employeeId = EmployeeNo);
                  
    -- drop temporary table
    DROP TABLE #deletedRecords;

COMMIT TRANSACTION;

Alternative way to create temporary tables by using SELECT INTO

BEGIN TRANSACTION;

    SELECT  e.EmployeeNo employeeId 
    INTO #deletedRecords
    FROM WorkRecord2 w
    INNER JOIN Employee e
           ON e.EmployeeNo = w.EmployeeRun
          AND w.Company = 1
          AND w.date = '2013-05-06';
          
    -- delete from WorkRecord2
    DELETE w
    FROM WorkRecord2 w
    INNER JOIN #deletedRecords d
           ON w.EmployeeRun = d.employeeId;
           
    -- delete from Employee using exists
    DELETE 
    FROM Employee
    WHERE EXISTS (SELECT 1
                  FROM #deletedRecords d
                  WHERE d.employeeId = EmployeeNo);
                  
    -- drop temporary table
    DROP TABLE #deletedRecords;

COMMIT TRANSACTION;

Use ON CASCADE DELETE during foreign key creation in child table. If remove parent table data then corresponding child table data is automatically deleted.
