Use data as criteria

[peshonzi]

Hello,



I've created two tables. Both of them contain Date-fields.
The first table is the GENERAL table, where I store data (NOT TIME!).
The SECOND table is used only to input Date.

So, I want to create a query that will filter the data from GENERAL, according to the Date that I've typed in the SECOND table, using a SQL code (something similar to SELECT FROM).

I want exactly a SQL code, because the situation is more difficult than I describe it. It's just to explain it simplier for understanding.

SELECT General.*
FROM General, CritTable
WHERE (((General.CaseDate)=[DateParam]));

General is the main data table. critTable is having only one field: DateParam and with only one record. Both Tables are placed on the Query Design surface. critTable should have only one record. More than one record will duplcate the output from the data table.

You can create a Query for the same output differently without placing the critTable on the Design Surface like:

SELECT General.*
FROM General
WHERE (((General.CaseDate)=DLookUp("DateParam","critTable")));

In this method we are using the Dlookup() Functiion to read and bring the date value from the DateParam field of critTable as criteria.

There is another method you can use for the same result with a Sub-Query in the criteria row like:

SELECT General.*
FROM General
WHERE (((General.CaseDate)=(SELECT DateParam FROM critTable;)));

You can use any of the three methods above.

Well, I've typed those three things, but non of that worked: "The syntax of the subquery in this expression is incorrect". (for all of them)

If this will help:

SELECT History.Zaqvitel, History.Belejka_nomer, History.Chas, History.Minyti, History.Obekt, History.Vid_beton, History.Himicheska_dobavka, History.Pompa, History.Shofior, History.Kolichestvo, History.Faktura, History.Vuzel, History.Date, Datata.Datata1
FROM History, Datata
ORDER BY History.Zaqvitel, History.Belejka_nomer;

The main table is - [History]
The date table is - [Datata]

The main date field is - [Date]
The help field is - [Datata1]

SELECT History.Zaqvitel, History.Belejka_nomer, History.Chas, History.Minyti, History.Obekt, History.Vid_beton, History.Himicheska_dobavka, History.Pompa, History.Shofior, History.Kolichestvo, History.Faktura, History.Vuzel, History.Date
FROM History, Datata
WHERE (History.Date = Datata.Datata1)
ORDER BY History.Zaqvitel, History.Belejka_nomer;

Honestly, it doesn't work...

Maybe I am too stupid for access..

I will attach you a Sample that I made...

There is a slight change of names - instead of [Date] - [Data], and maybe something else, that I missed to say... but it is quite a simple table!

Please, look at it, because I am getting discouraged...

PLEASE

I found the mistake - I was using a field with the name [date], which is an access special word, so that was the problem... Thanks a lot!
