I want to map right column to left but i am getting error at select statement as Incorrect syntax near 'select'.Expecting ID
create table [AdventureWorks2014].[abc] as
select a.*,
b.*
from [Production].[Product] a
left join(
select distinct ProductID,Shelf
from [Production].[ProductInventory]
)b
on a.ProductID = b. ProductID;
Try using SELECT INTO:
select p.*, pi.shelf
into [AdventureWorks2014].[abc]
from [Production].[Product] p left join
(select distinct ProductID, Shelf
from [Production].[ProductInventory] pi
) pi
on p.ProductID = pi.ProductID;
Notes:
I am not aware that SQL Server supports CREATE TABLE AS.
The columns in a table need to have unique names. If you use *, you will get ProductId twice.
Abbreviations of the table names is the best naming conventions; meaningless letters such as a and b should be avoided.

I have a table with multiple data for same ID. I want to get the first row data for the ID.
I have added the below SQL that I have tried.
SELECT
"client"."id",
"client"."company_name",
"client_details"."address"
from Client
LEFT OUTER JOIN "client_details" ON ("client"."id" = "client_details"."client_id")
Since I have multiple address for the same ID, can we get only the first id?
Currently the output I get is 2 rows with different addresses.
You can add to your SQL LIMIT 1 and in case you want to be sure the order you can also add to your SQL ORDER BY...
You can use distinct on:
select distinct on (c.id) c.id, c.company_name, cd.address
from Client c left join
client_details cd
on c.id = cd.client_id
order by c.id, ?;
The ? is for the column that specifies the ordering (the definition of "first"). I am guessing that cd.id is what you want.
Note that this query removes the double quotes and introduces table aliases. This is easier on both the eyes (to read) and the fingers (to type).
use row_number()
select * from
(
SELECT
"client"."id",
"client"."company_name",
"client_details"."address",row_number() over(partition by "client"."id" order by "client_details"."address") as rn
from Client
LEFT OUTER JOIN "client_details" ON "client"."id" = "client_details"."client_id"
)A where rn=1
If there is a field you can order the results by you could use a lateral join e.g.
SELECT
"client"."id",
"client"."company_name",
"client_details"."address"
from Client
left join lateral (
select *
from client_details cd
where cd.client_id = client.id
order by [some_ordering_field]
limit 1
) "client_details" on true
This query feeds a data table with sorting, filtering, and pagination. All features worked fine until I added the INNER JOIN and then i got:
The multi-part 'identifier "Types.Description" could not be bound
if i remove the second WHERE clause at the end of the query the LIKE statements work, but i lose pagination. I removed some of the LIKE clauses to try and clean up this monstrous query.
SELECT *
FROM (
SELECT ROW_NUMBER() OVER (ORDER BY TAG asc) AS RowNumber, *
FROM (
SELECT (SELECT COUNT(*) FROM Instruments) AS TotalDisplayRows, (SELECT COUNT(*) FROM Instruments) AS TotalRows, Instruments.Tag, Instruments.Location, Instruments.Description, Types.Description As TypeDesc, Manufacturer.Name, Lease.Name as LeaseName, Facility.Name as FacName
FROM Instruments
INNER JOIN Types ON Instruments.Type = Types.ID
INNER JOIN Manufacturer ON Instruments.Manufacturer = Manufacturer.ID
INNER JOIN Facility ON Instruments.Facility = Facility.ID
INNER JOIN Lease ON Instruments.Lease = Lease.ID
WHERE (Types.Description LIKE '%Cat%')
) RawResults
) Results
WHERE (Types.Description LIKE '%Cat%') AND RowNumber BETWEEN 1 AND 10
I think this is your problem
WHERE (types.description LIKE '%Cat%')
You can't do this because you are actually selecting from your derived table named Results and you aliased the column as TypeDesc.
So it should be
WHERE (results.typeDesc LIKE '%Cat%')
Can anyone who knows SQL, specifically the flavor used in Microsoft Access 2013, tell me what I'm doing wrong here?
SELECT custid, custname, ordno, itemno, itemname
FROM cust
INNER JOIN order
ON cust.custid = order.custid
INNER JOIN orderitems
ON order.ordno = orderitems.ordno
INNER JOIN inv
ON orderitems.itemno = inv.itemno;
I've already read other, similar questions, and tried the methods they used in their solutions, but I'm getting a "Syntax error in FROM clause.", almost no matter what I try.
* * *
SOLUTION: Thanks for the replies! In addition to adding square brackets around "order" and using TableName.ColumnName syntax in SELECT, I had to use parentheses for my multiple INNER JOINs. Here is the fixed code:
SELECT cust.custid, cust.custname, [order].ordno, orderitems.itemno, inv.itemname
FROM ((cust
INNER JOIN [order]
ON cust.custid = [order].custid)
INNER JOIN orderitems
ON [order].ordno = orderitems.ordno)
INNER JOIN inv
ON orderitems.itemno = inv.itemno;
SELECT cust.custid --<-- Use two part name here
,cust.custname
,[order].ordno
,orderitems.itemno --<-- Only guessing here use the correct table name
,inv.itemname --<-- Only guessing here use the correct table name
FROM cust
INNER JOIN [order]
ON cust.custid = [order].custid --<-- used square brackets [] around ORDER as it is
INNER JOIN orderitems -- a key word.
ON [order].ordno = orderitems.ordno
INNER JOIN inv
ON orderitems.itemno = inv.itemno;
In your Select Statament you need to use Two Part name i.e TableName.ColumnName since these column can exist in more than one Tables in your FROM clause you need to tell sql server that columns in your select coming from which table in your from clause.
I have two tables in SQL Server, tbl_disputes and tbl_disputetypes. The tbl_disputes table contains a foreign key column disputetype. The table tbl_disputetypes contains the primary key field disputetypeid and disputetypedesc. The following query gives me a count of each disputetype from the tbl_disputes table.
select disputetype, count(disputetype) as numberof
from tbl_disputes
group by disputetype
What sort of join or subquery do I need to use to display the
tbl_disputetypes.dbo.disputetypedesc instead of tbl_disputes.dbo.disputetype?
EDIT Issue was because disputetypedesc was set as TEXT. I changed it to nvarchar, and the following query worked:
SELECT
tbl_disputetypes.disputetypedesc,
count(tbl_disputetypes.disputetypedesc)
FROM
tbl_disputes Left OUTER JOIN
tbl_disputetypes ON tbl_disputes.disputetype = tbl_disputetypes.disputetypeid
group by tbl_disputetypes.disputetypedesc
Unless I'm missing something, you can just LEFT JOIN the description:
select disputetypedesc, count(disputetype) as numberof
from tbl_disputes d
LEFT JOIN tbl_disputetypes dt
ON dt.disputetypeid = d.disputetype
group by disputetypedesc
Assuming 2005+:
WITH x(t, numberof) AS
(
SELECT disputetype, COUNT(*)
FROM tbl_disputes
GROUP BY disputetype
)
SELECT dt.disputetypedesc, x.numberof
FROM tbl_disputetypes AS dt
INNER JOIN x ON dt.disputetype = x.t;
A simple JOIN?
select
DT.disputetypedesc, count(*) as numberof
from
tbl_disputes D
JOIN
tbl_disputetypes DT ON D.disputetype = DT.disputetype
group by
DT.disputetypedesc
The basic idea is that you will need a sub-query. Something like this will work:
select disputetypedesc, disputetype, numberof
from (select disputetype, count(disputetype) numberof
from tbl_disputes
group by disputetype) t left outer join
tbl_disputetypes on t.disputetype = tbl_disputetypes.disputetype
I am not sure if I understand your question however you should be able to select all columns using a query similar to the code sample below.
The following query will join the two tables by the disputetypeid column. I changed the format of the SQL statement however you can obviously format it however you would like.
SELECT tbl_disputetypes.disputetypedesc
, tbl_disputes.*
, <any_column_from_either_table>
FROM tbl_disputes
INNER JOIN tbl_disputetypes
ON tbl_disputes.disputetypeid = tbl_disputetypes.disputetypeid
I posted on Friday (sql multiple count) and had a few responses.
Having tried to implement them today, I keep getting the same error.
My SQL code now is:
SELECT MBDDX_STUDY.STUDY_NAME,
COUNT(MBDDX_EXPERIMENT.STUDY_ID)
AS NUMBER_OF_EXPERIMENTS
FROM MBDDX_STUDY
INNER JOIN MBDDX_EXPERIMENT
ON MBDDX_STUDY.ID = MBDDX_EXPERIMENT.STUDY_ID
INNER JOIN (SELECT COUNT(MBDDX_TREATMENT_GROUP.GROUP_NO)
FROM MBDDX_TREATMENT_GROUP)
ON MBDDX_TREATMENT_GROUP.STUDY_ID = MBDDX_STUDY.ID
GROUP BY MBDDX_STUDY.STUDY_NAME
I keep getting the error:
ORA-00904: "MBDDX_TREATMENT_GROUP"."STUDY_ID": invalid identifier
Is it because it is outside of the inner join bracket, i.e. out of scope? I am very new to SQL and cannot understand why it wont work. I can get it working using select subqueries (without joins) but I want to also be able to work with joins.
If it matters any I am using Toad for Oracle.
Thanks.
Because you join with a query. Give a name to that query, and refer to it that way:
SELECT MBDDX_STUDY.STUDY_NAME
, COUNT ( MBDDX_EXPERIMENT.STUDY_ID )
AS NUMBER_OF_EXPERIMENTS
FROM MBDDX_STUDY
INNER JOIN MBDDX_EXPERIMENT
ON MBDDX_STUDY.ID = MBDDX_EXPERIMENT.STUDY_ID
inner JOIN ( SELECT study_id, COUNT ( MBDDX_TREATMENT_GROUP.GROUP_NO )
FROM MBDDX_TREATMENT_GROUP group by study_id ) AS my_query
ON my_query.STUDY_ID = MBDDX_STUDY.ID
GROUP BY MBDDX_STUDY.STUDY_NAME
For one thing, a subquery must have an alias. Change:
inner JOIN ( SELECT COUNT ( MBDDX_TREATMENT_GROUP.GROUP_NO )
FROM MBDDX_TREATMENT_GROUP )
ON MBDDX_TREATMENT_GROUP.STUDY_ID = MBDDX_STUDY.ID
to
inner JOIN ( SELECT COUNT ( MBDDX_TREATMENT_GROUP.GROUP_NO )
FROM MBDDX_TREATMENT_GROUP ) as CountAlias
ON MBDDX_TREATMENT_GROUP.STUDY_ID = MBDDX_STUDY.ID
The second thing is that you have to include all columns you plan to use. Right now, the subquery just selects a count, but the ON clause references STUDY_ID. You can fix that by including STUDY_ID in the subquery select list, like:
inner JOIN (
SELECT STUDY_ID
, COUNT(MBDDX_TREATMENT_GROUP.GROUP_NO) as GroupCount
FROM MBDDX_TREATMENT_GROUP) as CountAlias
ON MBDDX_TREATMENT_GROUP.STUDY_ID = MBDDX_STUDY.ID
Now after that, you might hit other issues, but I'm hoping this will get you started.
