parameter query

[LP]

hi there
i want to create a parameter query which lets the user first select what
field on the db they need to query, before entering their own parameters for
that field. can this be done in a single query? how would you go about it?
regards
LP

Post your table structure indicating field names and datatype.
How many fields are you want to select from? Which ones?

 

[LP]

Thanks for your reply.
at the moment i just want to refer to 2 tables.
table1 has 8 fields users could query: FirstName (text), Surname (text),
Gender text), Ethnicity (text), FirstLanguage (text), DOB (date), Loop (Y/N),
DialARide (Y/N).
Table2 has 16 fields users could query: MembershipType (text), Date Joined
(date), LastUpdated (date), Executive (Y/N), MailoutFormat (text), Receive
Mailouts (Y/N), Address1 (text), Address2 (text), Address3 (text), Address4
(text), Postcode (text), Ward (text), Telephone (text), Fax (text), Email
(text), Wheelchair User (Y/N).

How are the tables related? I do not see a common field.

 

[LP]

there is a 121 relationship type between table1 and table2, table 1 being the
related table. table2 has a primary key (MemID) with autonumber as Data Type.
table 1 has a primary key (MemId) with number as Data Type.

Apparently you did not understand the question about how the tables are
related.
What field is common to both? When you have a manufactor and product table
one-to-many you need a field in the product table that matches a field for
manufactor.
I do not see such fields in your two tables. Table 1 is people and Table 2
is memberships. What fields connects the two?

 

[LP]

the only fields connecting the 2 tables are MemID (in table2) and MemId (in
table1)

Create an unbound form with unbound list box and text box. Populate list
with field names.

Create query in design view by adding all fields to the grid.

Use a query like this –
SELECT [Forms]![YourForm]![ListBox] AS Expr1, LPtable1.FirstName,
[Forms]![YourForm]![ListBox] AS Expr2, LPtable1.Surname,
[Forms]![YourForm]![ListBox] AS Expr3, LPtable1.Gender,
[Forms]![YourForm]![ListBox] AS Expr4, LPtable1.DOB, LPtable1.Ethnicity,
LPtable1.FirstLanguage, LPtable1.Loop, LPtable1.DialARide,
LPtable2.MembershipType, LPtable2.[Date Joined], LPtable2.LastUpdated,
LPtable2.Ethnicity, LPtable2.Executive, LPtable2.MailoutFormat,
LPtable2.[Receive Mailouts], LPtable2.Address1, LPtable2.Loop,
LPtable2.Address2, LPtable2.Address3, LPtable2.Address4, LPtable2.Postcode,
LPtable2.Ward, LPtable2.Telephone, LPtable2.Telephone, LPtable2.Fax,
LPtable2.Email, LPtable2.[Wheelchair User], LPtable2.[Wheelchair User]
FROM LPtable1 LEFT JOIN LPtable2 ON LPtable1.MemID = LPtable2.MemID
WHERE ((([Forms]![YourForm]![ListBox])="FirstName") AND
((LPtable1.FirstName) Like [Forms]![YourForm]![ListBox] & "*")) OR
((([Forms]![YourForm]![ListBox])="Surname") AND ((LPtable1.Surname) Like
[Forms]![YourForm]![ListBox] & "*")) OR
((([Forms]![YourForm]![ListBox])="Gender") AND ((LPtable1.Gender) Like
[Forms]![YourForm]![ListBox] & "*")) OR
((([Forms]![YourForm]![ListBox])="DOB") AND
((LPtable1.DOB)=[Forms]![YourForm]![ListBox]));

Your tables should be like this –
