Default Query Inside an SQL statement

Hi and TIA. What I'm wondering is can you use aquery name in place of a
table name when building an sql statement in code? Example below can I
replace MyTable with MyQuery. It bombs out on me when I run the code. My
goal is to creat several Union queries in my db. Have the user select
tables on my form to use in the results and depending on what they select I
will use that saved Union query in place of the table name (MyTable)
below.Thanks for your time.


Set db = CurrentDb()
Set qdf = db.QueryDefs("qryMultiSelect")
If Me!lstUIC_ID.ItemsSelected.Count 0 Then
For Each varItem In Me!lstUIC_ID.ItemsSelected
strCriteria = strCriteria & "MyTable.UIC = " & Chr(34) _
& Me!lstUIC_ID.ItemData(varItem) & Chr(34) & "OR "
Next varItem
strCriteria = Left(strCriteria, Len(strCriteria) - 3)
Else
strCriteria = "MyTable.UIC Like '*'"
End If
strSQL = "SELECT * FROM MyTable" & _
"WHERE " & strCriteria & ";"
qdf.SQL = strSQL
DoCmd.OpenQuery "9h1_qryMultiSelect"

Default Query Inside an SQL statement

You can.

Example below can I
replace MyTable with MyQuery. It bombs out on me when I run the code.

hmm, "bombs out" is not a quite accurate error description.

Set db = CurrentDb()
Set qdf = db.QueryDefs("qryMultiSelect")
If Me!lstUIC_ID.ItemsSelected.Count 0 Then
For Each varItem In Me!lstUIC_ID.ItemsSelected
strCriteria = strCriteria & "MyTable.UIC = " & Chr(34) _
& Me!lstUIC_ID.ItemData(varItem) & Chr(34) & "OR "
Next varItem
strCriteria = Left(strCriteria, Len(strCriteria) - 3)
Else
strCriteria = "MyTable.UIC Like '*'"
End If
strSQL = "SELECT * FROM MyTable" & _
"WHERE " & strCriteria & ";"
qdf.SQL = strSQL

Use Debug.Ptin strSQL to output the SQL statement to the immediate
window. Copy'n'paste it into a new query. Try to fix it. Then adjust
your code...

Yes. A saved query looks like a table to the query engine.

It bombs out on me when I run the code.

We're not looking over your shoulder at your screen. What is the error
message you get?

My goal is to creat several Union queries in my db.


? Why several union queries? Or do you mean to say you have created a union
query that combines the data from several tables?

Have the user select tables on my form to use in the results and
depending on what they select I will use that saved Union query in
place of the table name (MyTable) below.Thanks for your time.


Set db = CurrentDb()
Set qdf = db.QueryDefs("qryMultiSelect")
If Me!lstUIC_ID.ItemsSelected.Count 0 Then
For Each varItem In Me!lstUIC_ID.ItemsSelected
strCriteria = strCriteria & "MyTable.UIC = " & Chr(34) _
& Me!lstUIC_ID.ItemData(varItem) & Chr(34) &
"OR " Next varItem
strCriteria = Left(strCriteria, Len(strCriteria) - 3)
Else
strCriteria = "MyTable.UIC Like '*'"
End If
strSQL = "SELECT * FROM MyTable" & _
"WHERE " & strCriteria & ";"
qdf.SQL = strSQL


This sql statement will raise a syntax error because you have failed to put
a space between MyTable and WHERE. While debugging, you should look at the
results of your concatenation. You can do that by using msgbox or
debug.print.

debug.print strSQL

DoCmd.OpenQuery "9h1_qryMultiSelect"

Do you have a saved query called "9h1_qryMultiSelect"? if not, this last
line will raise an "object not found" error.

Does qryMultiSelect contain your union query? And does that union query
return a field called UIC? If so, your code is replacing that union query
with a simple select statement.

Or is there another saved query that does the union? And qryMultiSelect is
intended just to be used in your OpenQuery statement? If so, then you should
be able to use the name of that saved union query (whatever its name is) in
your sql. Like this:

strSQL = "SELECT * FROM qryUnion " & _
"WHERE " & strCriteria & ";"
qdf.SQL = strSQL
DoCmd.OpenQuery "qryMultiSelect"

My preference is not to display the results of a query in a query window.
Given that this is read-only data, I would create a report whose data source
is qryMultiSelect and use DoCmd.OpenReport instead. Alternatively, you can
use a subform whose form's data source is qryMultiSelect and use
subformname.Requery

Responses below:

Thanks All for your responses and sorry for my lame post. I figured out the
problem it was because the query name I am using has a leading number in the
name. Once I put the name in brackets it runs like a charm. Guess the
number was throwing off the sql statement.

This is correct. Using my list box on the form the user wil select a table
or a combination of the tables (only 3 off them)
Depending On their selection I will pass a string (strQueryName) to this
procedure containing the name of the predefined union query and use in place
of qryUnion you have below. The qryMultiSelect is just a holder query and
built on the fly

strSQL = "SELECT * FROM qryUnion " & _
"WHERE " & strCriteria & ";"
qdf.SQL = strSQL
DoCmd.OpenQuery "qryMultiSelect"

My preference is not to display the results of a query in a query window.

Yep. I'm simply exporting the results to excel.
