the query is this :
UPDATE ParametersMain2 INNER JOIN ParametersMain
ON ParametersMain2.VMV_CODE=ParametersMain.VMV_CODE
SET ParametersMain2.PARENT_VARIABLE_NAME=ParametersMain.PARENT_VARIABLE_NAME
AND ParametersMain2.VARIABLE_NAME=ParametersMain.VARIABLE_NAME;
Each time it says all the entries are being updated. each time i go look. the PARENT_VARIABLE_NAME fields and VARIABLE_NAME fields are still blank in ParametersMain2.
and the entire column of those fields are filled in in ParametersMain
why isntit working? i checked to see that its all the same data types and formats between the two tables.
Swap the AND with a comma, as below.
UPDATE
ParametersMain2
INNER JOIN
ParametersMain
ON ParametersMain2.VMV_CODE = ParametersMain.VMV_CODE
SET
ParametersMain2.PARENT_VARIABLE_NAME = ParametersMain.PARENT_VARIABLE_NAME ,
ParametersMain2.VARIABLE_NAME = ParametersMain.VARIABLE_NAME;
AND is operator that combines booleans (and nulls), if you want to set multiple fields separate them with a comma.

I have 2 tables, 1 containing the main body of information, the second contains information on country naming convensions. in the information table, countries are identified by Name, I would like to update this string to contain an ISO alpha 3 value which is contained in the naming convention table. e.g turning "United Kingdom" -> "GBR"
I have wrote the following query to make the update, but it effects 0 rows
UPDATE
`db.catagory.test_votes_ds`
SET
`db.catagory.test_votes_ds`.country = `db.catagory.ISO-Alpha`.Alpha_3_code
FROM
`db.catagory.ISO-Alpha`
WHERE
`LOWER(db.catagory.ISO-Alpha`.Country) = LOWER(`db.catagory.test_votes_ds`.country)
I've done an inner join outside of the update between the 2 to make sure that the values are compatable and it returns the correct value, any ideas as to why it isn't updating?
The join used to validate the result is listed below, along with the result:
SELECT
`db.catagory.test_votes_ds`.country, `db.catagory.ISO-Alpha`.Alpha_3_code
from
`db.catagory.test_votes_ds`
inner join
`db.catagory.ISO-Alpha`
on
LOWER(`db.catagory.test_votes_ds`.country) = LOWER(`db.catagory.ISO-Alpha`.Country)
1,Ireland,IRL
2,Australia,AUS
3,United States,USA
4,United Kingdom,GBR
This is not exactly an answer. But your test may not be sufficient. You need to check where the values do not match. So, to return those:
select tv.*
from `db.catagory.test_votes_ds` tv left join
`db.catagory.ISO-Alpha` a
on LOWER(tv.country) = LOWER(a.Country)
where a.Country IS NULL;
I suspect that you will find countries that do not match. So when you run the update, the matches are getting changed the first time. Then the non-matches are never changed.
Not sure why my field in my query is getting truncated upon the return of the result. The value is being stored in the field, but gets truncated by access to help with "performance". I have reviewed multiple forums and SO posts to no avail.

What is wrong with my query? Instructions field in the Customer table is the one that is getting truncated.
Here is the raw query generated by access:

Have a close read of this - http://allenbrowne.com/ser-63.html something in your set up will causing the truncation.
If it's when you cut and paste the query results that can also be mis-leading. When you say a Long Text are these linked tables?
I'd also rename your Min and Max fields as they are reserved words and may cause access to think you are aggregating your data.
So from the sounds of it, Access just sometimes will ALWAYS truncate the field no matter what the settings. There is a way to force access to show the entire field though, by using the DLOOKUP() function instead of using a Control Source.
Here is the Answer to my current Issue for reference,
=DLOOKUP("Instructions", "Customer", "CustID=" & [CustomerID])
I am very new to Access, and what I am trying to do seems like it should be very simple, but I can't seem to get it.
I am a structural engineer by trade and am making a database to design buildings.
My Diaphragm Analysis Table includes the fields "Floor_Name", "Story_Number", "Wall_Left", and "Wall_Right". I want to write a new query that looks in another query called "Shear_Wall_incremental_Deflection" and pulls information from it based on input from Diaphragm Analysis. I want to take the value in "Wall_Right" (SW01), find the corresponding value in "Shear_Wall_incremental_Deflection", and report the "Elastic_Deflection" corresponding to the "Story_Below" instead of the "Story_Number" in the Diaphragm Analysis Table. In the case where "Story_Number" = 1, "Story_Below" will be 0 and I want the output to be 0.
Same procedure for "Wall_Left", but I'm just taking it one step at a time.
It seems that I need to use a "DLookup" in the expression builder with TWO criteria, one that Wall_Right = Shear_Wall and one that Story_Number = Story_Below, but when I try this I just get errors.
"Shear_Wall_incremental_Deflection" includes shearwalls for all three stories, i.e. it starts at SW01 and goes through SWW for Story Number 3 and then starts again at SW01 for Story Number 2, and so on until Story Number 1. I only show a part of the query results in the image, but rest assured, there are "Elastic_Deflection" values for story numbers below 3.
Here is my attempt in the Expression Builder:
Right_Defl_in: IIf(IsNull([Diaphragm_Analysis]![Wall_Right]),0,DLookUp("[Elastic_Deflection_in]","[Shear_Wall_incremental_Deflection]","[Shear_Wall_incremental_Deflection]![Story_Below]=" & [Diaphragm_Analysis]![Story_Number]))
I know my join from Diaphragm_Analysis "Wall_Left" and "Wall_Right" must include all records from Diaphragm_Analysis and only those from "Shear_Wall_incremental_Deflection"![Shear_Walls] where the joined fields are equal, but that's about all I know.
Please let me know if I need to include more information or send out the database file.
Thanks for your help.
Diaphragm Analysis (Input Table)
Shear_Wall_incremental_Deflection (Partial Image of Query)
I think what you are missing is that you can and should join to Diaphragm_Analysis twice, first time to get the Story_Below value and second to use it to get the corresponding Elastic_Deflection value.
To handle the special case where Story_Below is zero, I would write a separate query (only requires one join this time) and 'OR together' the two queries using the UNION set operation (note the following SQL is untested):
SELECT swid.Floor_Name,
swid.Story_Number,
swid.Wall_Left,
da2.Elastic_Deflection AS Story_Below_Elastic_Deflection
FROM ( Shear_Wall_incremental_Deflection swid
INNER JOIN Diaphragm_Analysis da1
ON da1.ShearWall = swid.Wall_Left )
INNER JOIN Diaphragm_Analysis da2
ON da2.ShearWall = swid.Wall_Left
AND da2.Story_Number = da1.Story_Below
UNION
SELECT swid.Floor_Name,
swid.Story_Number,
swid.Wall_Left,
0 AS Story_Below_Elastic_Deflection
FROM Shear_Wall_incremental_Deflection swid
INNER JOIN Diaphragm_Analysis da1
ON da1.ShearWall = swid.Wall_Left
WHERE da1.Story_Below = 0;
I've assumed that there is no data where Story_Number is zero.
I have two tables and with column paperNo and some data regarding that paper. I am trying to search all data based on paper no. from both the tables. I have successfully written the query and it is retrieving the data successfully. but I have noticed that. If my paperNo contains zero(0) then the query is not searching for that data. And for the non zero contains paperNo it is retrieving the same record twice.
I don't understand what is going wrong. tried every thing.
Here is my Query .-
SELECT PaperDate.paperNo,
PaperDate.RAW_PAPER,
PaperDate.EDGE_SEALED,
PaperDate.HYDRO_120,
PaperDate.HYDRO_350,
PaperDate.CATALYST_1ST,
PaperDate.CATALYST_2ND,
PaperDate.SIC_350,
tblThicknessPaperDate.rawThickness,
tblThicknessPaperDate.catThickness,
tblThicknessPaperDate.sicThickness,
tblThicknessPaperDate.rejectedThickness
FROM tblThicknessPaperDate
FULL OUTER JOIN PaperDate ON PaperDate.paperNo =tblThicknessPaperDate.paperNo
WHERE (tblThicknessPaperDate.paperNo = #paperNo)
I would try:
FROM tblThicknessPaperDate
RIGHT JOIN PaperDate ON PaperDate.paperNo =tblThicknessPaperDate.paperNo
WHERE (PaperDate.paperNo = #paperNo)
The two changes are: swapping to a right join so even if a record isn't in tblThicknessPaperDate we will still see the record in PaperDate. The other change is to use PapterDate.paperNo in the where clause. Since tblThicknessPaperDate.paperNo could be null we don't want to use that in the where if we can avoid it.
SELECT PaperDate.paperNo,
PaperDate.RAW_PAPER,
PaperDate.EDGE_SEALED,
PaperDate.HYDRO_120,
PaperDate.HYDRO_350,
PaperDate.CATALYST_1ST,
PaperDate.CATALYST_2ND,
PaperDate.SIC_350,
tblThicknessPaperDate.rawThickness,
tblThicknessPaperDate.catThickness,
tblThicknessPaperDate.sicThickness,
tblThicknessPaperDate.rejectedThickness
FROM tblThicknessPaperDate
FULL OUTER JOIN PaperDate ON PaperDate.paperNo =tblThicknessPaperDate.paperNo
WHERE (tblThicknessPaperDate.paperNo = #papNo | PaperDate.paperNo = #paperNo)
I am trying to create a filter with SQL queries but am having trouble with numeric values linking to other tables.
Every time I try to link to another table, it takes the same record and repeats it for every element in the other table.
For example, here is query:
SELECT ELEMENTS.RID,TAXONOMIES.SHORT_DESCRIPTION,[type],ELEMENT_NAME,ELEMENT_ID,SUBSTITUTION_GROUPS.DESCRIPTION,namespace_prefix,datatype_localname
FROM ELEMENTS,SUBSTITUTION_GROUPS,TAXONOMIES,SCHEMAS,DATA_TYPES
WHERE ELEMENTS.TAXONOMY_ID = TAXONOMIES.RID AND ELEMENTS.ELEMENT_SCHEMA_ID = SCHEMAS.RID AND
ELEMENTS.DATA_TYPE_ID = DATA_TYPES.RID
AND ELEMENTS.SUBSTITUTION_GROUP_ID = 0
The last line is the actual filtering criteria.
Here is an example result:
There should only be ONE result (Item has an RID of 0). But it's repeating a copy of the one record for every result inside the substitution groups table (there's 4).
Here is my database schema for reference. The lines indicate relationships between tables and the circles indicate the values I want:
You're forgot to join between ELEMENTS and SUBSTITUTION_GROUPS in your query.
SELECT
ELEMENTS.RID,TAXONOMIES.SHORT_DESCRIPTION,[type],ELEMENT_NAME,ELEMENT_ID,SUBSTITUTION_GROUPS.DESCRIPTION,namespace_prefix,datatype_localname
FROM
ELEMENTS,SUBSTITUTION_GROUPS,TAXONOMIES,SCHEMAS,DATA_TYPES
WHERE
ELEMENTS.TAXONOMY_ID = TAXONOMIES.RID AND ELEMENTS.ELEMENT_SCHEMA_ID = SCHEMAS.RID
AND ELEMENTS.DATA_TYPE_ID = DATA_TYPES.RID
AND ELEMENTS.SUBSTITUTION_GROUP_ID = SUBSTITUTION_GROUPS.RID
AND ELEMENTS.SUBSTITUTION_GROUP_ID = 0
