I've been able to make a query using MS Access 2010 that does just what I want but I am having trouble doing so in SQLite3. Here is the Access SQL
SELECT pubacc_lo.*
FROM pubacc_en
LEFT JOIN pubacc_lo ON pubacc_en.call_sign = pubacc_lo.call_sign;
Basically it selects all of the columns in the pubacc_lo table and the rows where the call_sign fields are equal between the tables. This does not select any of the pubacc_en data into the final query in MS Access.
Playing around in SQLite 3, the closest I've gotten was
SELECT * FROM PUBACC_LO, PUBACC_EN WHERE PUBACC_en.call_sign=PUBACC_LO.call_sign
But this statement selects all of the data in the EN table along with the LO table (cross join?). I've tried some left outer joins but haven't had any luck. Any tips would be appreciated!
You should be able to use the same query as you got from Access. SQLite3 does support left outer joins.
As for your query, if you only want the fields from the LO table, then ask for that in your SELECT clause like this:
SELECT PUBACC_LO.*
FROM PUBACC_LO, PUBACC_EN
WHERE PUBACC_en.call_sign=PUBACC_LO.call_sign
but the problem here is that it will only return call_signs with entries in both tables, while the outer join from access will return all rows from PUBACC_EN irrespective of whether there is a corresponding PUBACC_LO entry..
SELECT pubacc_lo.* FROM PUBACC_LO, PUBACC_EN WHERE UBACC_en.call_sign=PUBACC_LO.call_sign
If you only want to select pubbac_lo's field, this is what you can use.

I am able to perform Union of two tables in MS Query of excel but its throwing error for "Except".
Can someone please let me know is there anyway to use "Except" of two tables in Excel.
SELECT * FROM [Book1query] tbl2
EXCEPT
SELECT * FROM [Merge1] tbl1
EXCEPT returns only rows, which are not available in the second SELECT statement. In other words, a join type of left anti.
In Power Query you can do that with a Merge of two tables, using the Join Kind option for Left Anti.

I am trying to convert a T-SQL query to MS Access SQL and getting a syntax error that I am struggling to find. My MS Access SQL query looks like this:
INSERT INTO IndvRFM_PreSort (CustNum, IndvID, IndvRScore, IndRecency, IndvFreq, IndvMonVal )
SELECT
IndvMast.CustNum, IndvMast.IndvID, IndvMast.IndvRScore,
IndvMast.IndRecency, IndvMast.IndvFreq, IndvMast.IndvMonVal
FROM
IndvMast
INNER JOIN
OHdrMast ON IndvMast.IndvID = OHdrMast.IndvID
INNER JOIN
MyParameterSettings on 1=1].ProdClass
INNER JOIN
[SalesTerritoryFilter_Check all that apply] ON IndvMast.SalesTerr = [SalesTerritoryFilter_Check all that apply].SalesTerr
WHERE
(((OHdrMast.OrdDate) >= [MyParameterSettings].[RFM_StartDate]))
GROUP BY
IndvMast.CustNum, IndvMast.IndvID, IndvMast.IndvRScore,
IndvMast.IndRecency, IndvMast.IndvFreq, IndvMast.IndvMonVal,
[CustTypeFilter_Check all that apply].IncludeInRFM,
[ProductClassFilter_Check all that apply].IncludeInRFM,
[SourceCodeFilter_Check all that apply].IncludeInRFM,
IndvMast.FlgDontUse
I have reviewed differences between MS Access SQL and T-SQL at http://rogersaccessblog.blogspot.com/2013/05/what-are-differences-between-access-sql.html and a few other locations but with no luck.
All help is appreciated.
update: I have removed many lines trying to find the syntax error and I am still getting the same error when running just (which runs fine using T-SQL):
SELECT
IndvMast.CustNum, IndvMast.IndvID, IndvMast.IndvRScore,
IndvMast.IndRecency, IndvMast.IndvFreq, IndvMast.IndvMonVal
FROM
IndvMast
INNER JOIN
OHdrMast ON IndvMast.IndvID = OHdrMast.IndvID
INNER JOIN
[My Parameter Settings] ON 1 = 1
There are a number of items in your query that should also have failed in any SQL-compliant database:
You have fields from tables in GROUP BY not referenced in FROM or JOIN clauses.
Number of fields in SELECT query do not match number of fields in INSERT INTO clause.
The MyParameterSettings table is not properly joined with valid ON expression.
Strictly MS Access SQL items:
For more than one join, MS Access SQL requires paired parentheses but even this can get tricky if some tables are joined together and their paired result joins to outer where you get nested joins.
Expressions like ON 1=1 must be used in WHERE clause and for cross join tables as MyParameterSettings appears to be, use comma-separated tables.
For above reasons and more, it is advised for beginners to this SQL dialect to use the Query Design builder providing table diagrams and links (if you have the MS Access GUI .exe of course). Then, once all tables connect graphically with at least one field selected, jump into SQL view for any nuanced scripting logic.
Below is an adjustment to SQL statement to demonstrate the parentheses pairings and for best practices, uses table aliases especially with long table names.
INSERT INTO IndvRFM_PreSort (CustNum, IndvID, IndvRScore, IndRecency, IndvFreq, IndvMonVal)
SELECT
i.CustNum, i.IndvID, i.IndvRScore, i.IndRecency, i.IndvFreq, i.IndvMonVal
FROM
[MyParameterSettings] p, (IndvMast i
INNER JOIN
OHdrMast o ON i.IndvID = o.IndvID)
INNER JOIN
[SalesTerritoryFilter_Check all that apply] s ON i.SalesTerr = s.SalesTerr
WHERE
(o.OrdDate >= p.[RFM_StartDate])
GROUP BY
i.CustNum, i.IndvID, i.IndvRScore, i.IndRecency, i.IndvFreq, i.IndvMonVal
And in your smaller SQL subset, the last table does not need an ON 1=1 condition and may be redundant as well in SQL Server. Simply a comma separate table will suffice if you intend for cross join. The same is done in above example:
SELECT
IndvMast.CustNum, IndvMast.IndvID, IndvMast.IndvRScore,
IndvMast.IndRecency, IndvMast.IndvFreq, IndvMast.IndvMonVal
FROM
[My Parameter Settings], IndvMast
INNER JOIN
OHdrMast ON IndvMast.IndvID = OHdrMast.IndvID
I suppose there are some errors in your query, the first (more important).
Why do you use HAVING clause to add these conditions?
HAVING (((IndvMast.IndRecency)>(date()-7200))
AND (([CustTypeFilter_Check all that apply].IncludeInRFM)=1)
AND (([ProductClassFilter_Check all that apply].IncludeInRFM)=1)
AND (([SourceCodeFilter_Check all that apply].IncludeInRFM)=1)
AND ((IndvMast.FlgDontUse) Is Null))
HAVING usually used about conditions on aggregate functions (COUNT, SUM, MAX, MIN, AVG), for scalar value you must put in WHERE clause.
The second: You have 12 parenthesis opened and 11 closed in HAVING clause
a select query for Multiple tables with one Common Column
i have tried something below but not working
Select * from DM_Audit da, DM_APPLICANTS dap , DM_POLICY dp, DM_Names dn,DM_Address ad
where da.fk_applicationID=dap.fk_applicationID and
dap.fk_applicationID=dp.fk_applicationID and
dp.fk_applicationID=dn.fk_applicationID and
dn.fk_applicationID=ad.fk_applicationID
Here fk_applicationID is Common column in all the table
New to the Sql Please Help
The column name may be the same, but does it reference data for the intended records in each table?
If it definitely does, then re-writing the query using joins would be an easier way of checking the links:
Select *
from DM_Audit da
INNER JOIN DM_APPLICANTS dap ON dap.fk_applicationID=da.fk_applicationID
etc........
I would usually have a 'key' table in this situation (i.e. with the most data in it, or one which links to the most other tables which need to be joined) Then it is much easier to join the other tables.
N.B. if not all tables join to the key table, join as many as you can first, then join to the 'joined' tables further down the statement.
I am joining 2 tables using RIGHT JOIN statement. I used below query and it works good. However it still display all data whenever I tried to select specific user
SELECT TBLNOTIFICATIONS.NOTIFICATION_ID, TBLNOTIFICATIONS.NOTIFICATION_TYPE, FILENAMES_LIST.LOCATION_FILENAME, TBLNOTIFICATIONS.NOTIFICATION_DATE
FROM TBLNOTIFICATIONS
RIGHT JOIN FILENAMES_LIST
ON TBLNOTIFICATIONS.NOTIFICATION_ID=FILENAMES_LIST.NOTIFICATION_ID
WHERE TBLNOTIFICATIONS.USER_ID='JCON'
What should I do to select data from specific user?
Thanks in advance.
You are filtering on the left table, so all the data of the right table will still be shown.
It is probably enough to change the query to a LEFT JOIN to get the results you want.
Besides that, you can use aliases to make your query more readable, like so:
SELECT tn.NOTIFICATION_ID, tn.NOTIFICATION_TYPE, fl.LOCATION_FILENAME, tn.NOTIFICATION_DATE
FROM TBLNOTIFICATIONS AS tn
LEFT JOIN FILENAMES_LIST AS fl
ON tn.NOTIFICATION_ID = fl.NOTIFICATION_ID
WHERE tn.USER_ID='JCON'
Is there a way of joining results from 2 tables without using JOIN or SELECT from more than one table? The reason being the database im working with requires queries that only contain SELECT, FROM, and WHERE clauses containing only one distinct table. I do, however, need information from other tables for the project i'm working on.
More info: the querier returns the query results in a .csv format, is there something we can manipulate there?
Pick a programming language. Any language will do. Run one query, and get the results. Run another query, get the results. Use the programming language to combine the results.
Seriously. You are asking how to join data from a database that doesn't support joins. If the database doesn't support it, you're going to have to do it externally.
select a.*, b.* from tablea a, tableb b
You can do it either by Using JOIN or SELECT. You have to use one of it. By Join you must be knowing. I am writing an example for without using JOIN and just using SELECT, to join two tables.
SELECT * from Table1, Table2 where Table1.common_attribute = Table2.common_attribute;
