Using a string value in a SQL query in VBA

Good Day,

I have a query that is setting the recordset of a subform from a main form in access 2010. There are issues with using a variable to change the WHERE clause at runtime.

Does anyone know how to get a string variable to function within a SQL string in VBA?

Code below:
' dim array variables
Dim thismonth As String
Dim Gecsfieldname As String
Dim Morfieldname As String
Dim BinList As String

'Set Variable values
thismonth = Me.Monthlist
BinList = Me.BinList
'Gecsfieldname = "[Fused_MOR].[GECS_MOR_ChartDBSource_Template" & thismonth & "]"
'Morfieldname = "[Fused_MOR].[MOR_ChartDBSource_Template" & thismonth & "]"

Gecsfieldname = "[Fused_MOR].[GECS_MOR_ChartDBSource_TemplateMar]"
Morfieldname = "[Fused_MOR].[GECS_MOR_ChartDBSource_TemplateMar]"

MsgBox thismonth
MsgBox Gecsfieldname
MsgBox Morfieldname
MsgBox BinList

Forms![CompareMonthsForm]![Fused_MORsubform].Form.RecordSource = "SELECT Fused_MOR.GECS_MOR_ChartDBSource_TemplateMOR_GROUP, Fused_MOR.MOR_ChartDBSource_TemplateMOR_GROUP," & _
"Fused_MOR.GECS_MOR_ChartDBSource_TemplateCHARTDB_BIN , Fused_MOR.MOR_ChartDBSource_TemplateCHARTDB_BIN, Fused_MOR.GECS_MOR_ChartDBSource_TemplateORG_ABBR, " & _
"Fused_MOR.MOR_ChartDBSource_TemplateORG_ABBR, Fused_MOR.GECS_MOR_ChartDBSource_TemplateYEAR, Fused_MOR.MOR_ChartDBSource_TemplateYEAR, " & _
"Fused_MOR.GECS_MOR_ChartDBSource_TemplateJan, Fused_MOR.MOR_ChartDBSource_TemplateJan, Fused_MOR.GECS_MOR_ChartDBSource_TemplateFeb, " & _
"Fused_MOR.MOR_ChartDBSource_TemplateFeb, Fused_MOR.GECS_MOR_ChartDBSource_TemplateMar, Fused_MOR.MOR_ChartDBSource_TemplateMar, " & _
"Fused_MOR.GECS_MOR_ChartDBSource_TemplateApr, Fused_MOR.MOR_ChartDBSource_TemplateApr, Fused_MOR.GECS_MOR_ChartDBSource_TemplateMay, " & _
"Fused_MOR.MOR_ChartDBSource_TemplateMay, Fused_MOR.GECS_MOR_ChartDBSource_TemplateJun, Fused_MOR.MOR_ChartDBSource_TemplateJun, " & _
"Fused_MOR.GECS_MOR_ChartDBSource_TemplateJul, Fused_MOR.MOR_ChartDBSource_TemplateJul, Fused_MOR.GECS_MOR_ChartDBSource_TemplateAug, " & _
"Fused_MOR.MOR_ChartDBSource_TemplateAug, Fused_MOR.GECS_MOR_ChartDBSource_TemplateSep, Fused_MOR.MOR_ChartDBSource_TemplateSep, " & _
"Fused_MOR.GECS_MOR_ChartDBSource_TemplateOct, Fused_MOR.MOR_ChartDBSource_TemplateOct, Fused_MOR.GECS_MOR_ChartDBSource_TemplateNov, " & _
"Fused_MOR.MOR_ChartDBSource_TemplateNov, Fused_MOR.GECS_MOR_ChartDBSource_TemplateDec, Fused_MOR.MOR_ChartDBSource_TemplateDec " & _
"FROM Fused_MOR " & _
"WHERE (((Fused_MOR.MOR_ChartDBSource_TemplateMar) Not Like [Fused_MOR].[GECS_MOR_ChartDBSource_TemplateMar]));"

if you want to use string variables in SQL statments you need to wrap the variable name with apostrophes. Try this...

Forms![CompareMonthsForm]![Fused_MORsubform].Form.RecordSource = "SELECT Fused_MOR.GECS_MOR_ChartDBSource_TemplateMOR_GROUP, Fused_MOR.MOR_ChartDBSource_TemplateMOR_GROUP," & _
"Fused_MOR.GECS_MOR_ChartDBSource_TemplateCHARTDB_BIN , Fused_MOR.MOR_ChartDBSource_TemplateCHARTDB_BIN, Fused_MOR.GECS_MOR_ChartDBSource_TemplateORG_ABBR, " & _
"Fused_MOR.MOR_ChartDBSource_TemplateORG_ABBR, Fused_MOR.GECS_MOR_ChartDBSource_TemplateYEAR, Fused_MOR.MOR_ChartDBSource_TemplateYEAR, " & _
"Fused_MOR.GECS_MOR_ChartDBSource_TemplateJan, Fused_MOR.MOR_ChartDBSource_TemplateJan, Fused_MOR.GECS_MOR_ChartDBSource_TemplateFeb, " & _
"Fused_MOR.MOR_ChartDBSource_TemplateFeb, Fused_MOR.GECS_MOR_ChartDBSource_TemplateMar, Fused_MOR.MOR_ChartDBSource_TemplateMar, " & _
"Fused_MOR.GECS_MOR_ChartDBSource_TemplateApr, Fused_MOR.MOR_ChartDBSource_TemplateApr, Fused_MOR.GECS_MOR_ChartDBSource_TemplateMay, " & _
"Fused_MOR.MOR_ChartDBSource_TemplateMay, Fused_MOR.GECS_MOR_ChartDBSource_TemplateJun, Fused_MOR.MOR_ChartDBSource_TemplateJun, " & _
"Fused_MOR.GECS_MOR_ChartDBSource_TemplateJul, Fused_MOR.MOR_ChartDBSource_TemplateJul, Fused_MOR.GECS_MOR_ChartDBSource_TemplateAug, " & _
"Fused_MOR.MOR_ChartDBSource_TemplateAug, Fused_MOR.GECS_MOR_ChartDBSource_TemplateSep, Fused_MOR.MOR_ChartDBSource_TemplateSep, " & _
"Fused_MOR.GECS_MOR_ChartDBSource_TemplateOct, Fused_MOR.MOR_ChartDBSource_TemplateOct, Fused_MOR.GECS_MOR_ChartDBSource_TemplateNov, " & _
"Fused_MOR.MOR_ChartDBSource_TemplateNov, Fused_MOR.GECS_MOR_ChartDBSource_TemplateDec, Fused_MOR.MOR_ChartDBSource_TemplateDec " & _
"FROM Fused_MOR " & _
"WHERE  (((Fused_MOR.MOR_ChartDBSource_TemplateMar) Not Like "'" & [Fused_MOR].[GECS_MOR_ChartDBSource_TemplateMar] & "'" ));"

What string variable do you want in the SQL?

In general this is how you would add a string variable to your criteria.

"WHERE  (((Fused_MOR.MOR_ChartDBSource_TemplateMar) Not Like '"& YourStringVariable "'"

Yes, I agree, however, I can not get it to function.
Basically, it is set up like this.
the Main form has a combo box that is defined in the code
thismonth = me.monthlist

Then that value would be placed into the query by concatenating the two WHERE variables like this:
Gecsfieldname = "[Fused_MOR].[GECS_MOR_ChartDBSource_Template" & thismonth & "]"
so, depending upon the month value from the main form, the string could be something this
[Fused_MOR].[GECS_MOR_ChartDBSource_TemplateJan
or
[Fused_MOR].[GECS_MOR_ChartDBSource_TemplateFeb
or
[Fused_MOR].[GECS_MOR_ChartDBSource_TemplateMar

I have tried
Where "" '" & Morfieldname & "'"" not like "" '" & Gecsfieldname & "'"" ;"
Where " ' & Morfieldname & '" not like " ' & Gecsfieldname & '" ;"
Where Chr$(34) & Morfieldname & Chr$(34) not like Chr$(34) & Gecsfieldname & Chr$(34)

If I 'hard code' it, it functions, if the variable is used, it fails.

Thank you for the input !!

try

"Where " & Morfieldname & " not like " & "'" & Gecsfieldname & "';"

Umm, How would one set up the variables?

Like this
Gecsfieldname = "[Fused_MOR].[GECS_MOR_ChartDBSource_Template" & thismonth & "]"
Morfieldname = "[Fused_MOR].[MOR_ChartDBSource_Template" & thismonth & "]"

or maybe like this

Gecsfieldname = "Fused_MOR.GECS_MOR_ChartDBSource_Template" & thismonth & "
Morfieldname = "Fused_MOR.MOR_ChartDBSource_Template" & thismonth & "

How would one set these values up?

This information was very useful, and, ultimately lead me to the solution. Since the number of queries is limited to the months in a year (12), I simpley hard coded the different circumstances since each query only had a variance of 6 characters. these were quickly created using the replace function.
Thanks for the education.

PatHartman

You're welcome.

Yes, there are only 12 months in a year but normalizing the schema is still better and ultimately will save you work.

I hear you, however this was a 'one off' for comparative purposes. It is not going to be developed. Thanks again !
