1. Microsoft Sql Is Not Null

I have a combo box on my form that will filter my query criteria. In my combo box, I have the selection ' to allow all data to show. I put this statement in the Query criteria box: IIf(Forms!frmJobList!cboCategory=',Is Not Null,Forms!frmJobList!cboCategory) If I select from the combo box, the query returns no data.

If I select an alternative selection (that is in the table) then the query returns the data. The error is obviously in the 'True' part (Is Not Null).

May 21, 2014 I have the following SQL statement that I've been using against an Access Database (I've changed the # for date query): SELECT IIF(ISNULL(.)=TRUE,0.)- IIF. Dec 03, 2008 =IIf([SomeField] Is Not Null,'Not Null','Null') In a query: NewField: IIf([SomeField] Is Not Null,'Not Null','Null') This will cause 'Not Null' or 'Null' to appear in the text box or query field. Substitute the actual actions you would have performed. In all cases use the actual field name. In the query you can name the field as you choose. (MSSL 2008) SELECT IIF(Field1 IS NULL, 'NULL', 'NOT NULL') *** XX FROM MyTable [color. SQL Server Security Skills Microsoft Access Microsoft Access Products.

But when I use Is Not Null by itself, I get all the data. Any thoughts as to what I am doing wrong? If you're using the iif statement below to create a text string that goes into a query, i would think that you would need to put quotes around 'Is not null'.

Microsoft Sql Is Not Null

Though when you put quotes around it, I believe it is actually looking for the string 'Is Not Null' in the field and not all records that are not null Now if I substitute an actual selection from the combo box the query works as expected. So the error definitely seems to point to the Is Not Null within the Iif statement.

Ex: IIf(Forms!frmJobList!cboCategory=','Atlas',Forms!frmJobList!cboCategory) returns all records containing Atlas I've even tried: IIf(Forms!frmJobList!cboCategory=',Forms!frmJobList!cboCategory) thinking I might be able to leave the criteria blank. I've also tried the reverse to no avail: IIf(Forms!frmJobList!cboCategory',Forms!frmJobList!cboCategory,Is Not Null) Thanks for the thoughts. Any other ideas while I go back to searching? Could you show me the entire code sentence? Try: strSQL = 'SELECT. FROM Table WHERE Category ' & IIf(Forms!frmJobList!cboCategory=','Is Not Null','=Forms!frmJobList!cboCategory') & ' SELECT txtJobID, txtJobCategory, txtJobStatus FROM tblJobTracking WHERE (((txtJobCategory)=IIf(Forms!frmJobList!cboCategory=',Is Not Null,Forms!frmJobList!cboCategory)); I did try it with quotes around Is Not Null. When I do that it actually looks for the string 'Is Not Null' in the field.

It does not return all fields that are not null.
