Insert into Not Exists SQL Access

Insert INTO NOT EXISTS SQL access

You need a correlation clause. The subquery just checks whether or not the table is empty. Something like:

INSERT INTO ShouldImportMetricsIDsTable( [Formulary ID], [Market Segment] )
    SELECT im.[Formulary ID], im.[Market Segment]
    FROM ImportMetricsIDs01262015 as im
    WHERE NOT EXISTS (SELECT 1
                      FROM ShouldImportMetricsIDsTable as sim
                      WHERE im.[Formulary ID] = sim.[Formulary ID] AND
                            im.[Market Segment] = sim.[Market Segment]
                     );

insert into if not exists ms-access

Instead of VALUES you should use SELECT but even then Access wouldn't allow SELECT without FROM.

So the workaround is to use after FROM a query that returns always exactly 1 row, like:

SELECT MIN(id) FROM table_a

Instead of MIN() you could use FIRST().

So your code should be:

INSERT INTO table_a([name]) 
SELECT @name_
FROM (SELECT MIN(id) FROM table_a) AS t
WHERE NOT EXISTS (SELECT 1 FROM table_a WHERE [name] = @name_);

MS Access SQL Insert Into table where records do not exist

You need a correlated subquery, such as:

SELECT DISTINCT td.WardID, td.ConsultantID
FROM tblTempData as td
WHERE NOT EXISTS (SELECT twc.WardID, twc.ConsultantID
                  FROM tblWardConsultant as twc
                  WHERE twc.WardId = td.WardId AND twc.ConsultantId = tw.ConsultantId
                 ) AND 
      td.WardID IS NOT NULL AND
      td.ConsultantID IS NOT NULL;

INSERT IF NO EXISTS in access

I would do something like this: check to see if the code exists in the Orders table and if it doesn't, then run your Insert Into SQL. You might have to play with this a bit, depending on if your Code field is a TEXT or an INT, but this should get you most of the way there.

Dim db as Database
Dim rec as Recordset
Dim sSQL as String

Set db = CurrentDB
Set rec = db.OpenRecordset("Select * from Orders WHERE Code = '" & Me.Code & "'")

'This refreshes the dataset so you can get an accurate record count
rec.MoveFirst
rec.MoveLast

'If your record count is 0, then the code isn't in the DB yet so you need to add it
If rec.RecordCount = 0 Then
  sSQL = "INSERT INTO providers (provider,code) VALUES ('"&Me!provider&"','"&Me!code&"')";
  DoCmd.RunSQL sSQL
EndIf

'Always set your connection variables to Nothing so the connection closes!
Set db = Nothing
Set rec = Nothing

Using insert into where not exists in VBA

Well instead of using a SubQuery, you could use a Domain function to get this going,

If Dcount("*", "tbl_MAP_systemTask", "TaskID = " & taskID & " AND SystemID = " &sysID) = 0 Then
    strSQL = "INSERT INTO tbl_MAP_systemTask (TaskID, SystemID) " & _
             " VALUES (" & taskID & ", " & sysID & ")
    CurrentDb.Execute strSQL
Else
    MsgBox "The Data already exists in the table, so nothing was added."
End If

Access97: INSERT INTO if not exists

You can build that into an insert . .. select:

INSERT INTO Users (FirstName, LastName)
    SELECT TOP 1 'John', 'Smith'
    FROM Users
    WHERE NOT EXISTS ( SELECT 1 FROM Users WHERE FirstName = 'John' AND LastName = 'Smith' );

SQL INSERT INTO does not work my Access database

CURRENCY is a reserved word in Access SQL, so if you have a column with that name you must enclose it in square brackets. That is, this will fail with "Syntax error in INSERT INTO statement." ...

crsr.execute("INSERT INTO Strategy (CURRENCY) VALUES ('USD')")

... but this will work:

crsr.execute("INSERT INTO Strategy ([CURRENCY]) VALUES ('USD')")
