I want to insert into a table an value from variable and an select result.
declare #actual Date
set #actual = getdate()
This is my try:
insert into test (ID, Date) (select ID, #actual from Table)
I get an error Message!!
use INSERT INTO..SELECT statement,
DECLARE #actual Date
SET #actual = GETDATE()
INSERT INTO test (ID, Date)
SELECT ID, #actual
FROM Tablename
You can try like this for using a select clause for Insert
insert into test(id,date) select col1,col2 from table;
INSERT INTO TEST
(ID,DATE)
SELECT COLUMN1,COLUMN2 FROM TABLE

I have a Database and i want to execute few queries on it, and the results of the queries i.e. message, has to be comapared in my code if it is expected or not.
Please let me know how to capture the output of the SQL queries in any variable that can be used later in code for comparision.
Try the following Method :
Create a Table with the Same structure as of your Procedure output
Insert the Result of the SP Execution to the Table
Compare your Query result with the Table
Like this
CREATE PROCEDURE dbo.uSp_Temp
AS
SELECT
GETDATE() "MyDate"
DECLARE #T TABLE
(
MyDate DATE
)
INSERT INTO #T
EXEC uSp_Temp
SELECT
*
FROM #T
You can use Temp tables or temp variable to save the result set of a query.
Below is the sample for temp table
create table #temp (id int)
insert into #temp
select 1 as id
select * from #temp
Below is sample for Temp variable
declare #temp table (id int)
insert into #temp
select 1 as id
select * from #temp
I want to add empty rows to results fetched from a select statement. For example, if the select query fetch 4 rows then 2 empty rows needs to be fetched. Objective should be the number of rows fetched should be 6 every time. The number of rows fetched will be 6 maximum if there are 6 rows with data.
Any idea?
In SQL-SERVER You can create temp table to update It with empty rows and you can use WHILE to insert desired number of rows with empty values. Something like:
-- Create temp table to update data with empty rows
CREATE TABLE #HoldEmptyRows
(
Id NVARCHAR(20),
CustomerName NVARCHAR(20),
CustomerEmail NVARCHAR(20)
)
-- Insert data from SourceTable to temp
INSERT INTO #HoldEmptyRows
SELECT * FROM SourceTable
-- Do while count from temp table < of desired number insert empty rows
WHILE ((SELECT COUNT(*) cnt FROM #HoldEmptyRows) < 6)
BEGIN
INSERT INTO #HoldEmptyRows VALUES ('', '', '')
END
SELECT * FROM #HoldEmptyRows
DEMO AT SQL FIDDLE
Try the below logic:
with cte as
(
select 0 as col1
union all
select col1+1 from cte where cte.col1<10
)
select * into #temp1 from cte
create table #test
(rownum int,col1 varchar(100))
declare #i int=1
while (#i<=6)
begin
insert into #test
select * from
(select row_Number() over (order by (Select 0))rownum, * from #temp1)x
where rownum=#i
Set #i=#i+1
end
select case when rownum>4 then '' else col1 end as col1 from #test
I have a temp table declared
declare #tmptable(
value nvarchar(500) not null
);
I use a function to insert values into that temp table.
I am trying to figure out how to update a table using the values of #tmptable
insert into t1 (
active
,SchoolId
,inserted
)
select
1
,temp.value
,#insertedDate
select temp.value from #tmptable;
When i try to insert in table t1 it doesn't work. I guess there are two Select statements is causing the problem. Please let me know how to fix it. Thanks
Try this one -
INSERT INTO dbo.t1
(
Active
, SchoolId
, Inserted
)
SELECT
1
, t.value
, #insertedDate
FROM #tmptable t;
INSERT INTO t1
(
ACTIVE
,SchoolId
,INSERTED
)
SELECT 1
,temp.value
,#insertedDate
FROM #tmptable temp;
insert into t1 (
active
,SchoolId
,inserted
)
select
1
,temp.value
,#insertedDate
from #tmptable;
this will work...
I am trying to run a query given three tables.
DECLARE #TABLE1 TABLE (ID CHAR(2))
DECLARE #TABLE2 TABLE (ID CHAR(2))
DECLARE #TABLE3 TABLE (ID CHAR(2))
INSERT INTO #TABLE1 VALUES('1')
INSERT INTO #TABLE1 VALUES('2')
INSERT INTO #TABLE2 VALUES('1')
--NOTHING in TABLE3
I Need to get only the values that are present and ignore the null table. This doesn't work since TABLE3 has no values.
SELECT ID
FROM #TABLE1
INTERSECT
SELECT ID
FROM #TABLE2
INTERSECT
SELECT ID
FROM #TABLE3
**Result should be 1**
How do I ignore the any table if it's null but keep the other values?
Why not do a union of select distincts from each table, and then group that by ID and select count(*), and select only rows with count(*) equal to the maximum value of count(*) in the result?
It's a bit of a mess of subqueries at this point unfortunately but you should get the logic :)
Intersect is not going to work for you as you can't add conditions to it.
From what I understand you want to select all records where the ID appears in at least 2 of the tables. I am assuming that the ID is unique to each table.
The following works in MS SQL Server:
DECLARE #TABLE1 TABLE (ID CHAR(2))
DECLARE #TABLE2 TABLE (ID CHAR(2))
DECLARE #TABLE3 TABLE (ID CHAR(2))
INSERT INTO #TABLE1 VALUES('1')
INSERT INTO #TABLE1 VALUES('2')
INSERT INTO #TABLE2 VALUES('1')
--NOTHING in TABLE3
;WITH AllValues AS
(
SELECT ID
FROM #TABLE1
UNION ALL
SELECT ID
FROM #TABLE2
UNION ALL
SELECT ID
FROM #TABLE3
)
SELECT ID
FROM AllValues
GROUP BY ID
HAVING COUNT(*) > 1
Maybe... But the design of the system is extremely foreign; a real world example would help understand what you're trying to do.
Select count(*), ID FROM (
Select ID from #table1
UNION
Select ID from #table2
UNION
Select ID from #table3) Derived
Where RowNum =1
GROUP BY ID
ORder by count(*) DESC
Updated where clause was in wrong place
I have a simple problem , Although i believe its simple , am not able to figure out the same.
Consider i have the below table with exactly same data as given below :
CREATE TABLE #temp
(
link varchar(255),
number INT,
fname varchar(255)
)
insert into #temp VALUES ('abc',1,'f1')
insert into #temp VALUES ('abc',2,'f2')
insert into #temp VALUES ('abc',3,'f3')
insert into #temp VALUES ('abc',4,'f6')
insert into #temp VALUES ('abc',10,'f100')
insert into #temp VALUES ('abe',-1,'f0')
insert into #temp VALUES ('abe',1,'f1')
insert into #temp VALUES ('abe',2,'f2')
insert into #temp VALUES ('abe',3,'f3')
insert into #temp VALUES ('abe',4,'f6')
insert into #temp VALUES ('abe',20,'f200')
insert into #temp VALUES ('cbe',-1,'f0')
insert into #temp VALUES ('cbe',1,'f1')
insert into #temp VALUES ('cbe',2,'f2')
insert into #temp VALUES ('cbe',3,'f3')
Now for a given link , i need to get the max 'number' and the corresponding 'fname' which has the max 'number' for the given 'link'.
1)Ex : if link is 'abc' , output should be
abc, 10, f100
2)Ex : if link if 'abe' , Output should be
abe, 20, f200
3)Now link can be also given as a pattern , like (link like 'ab%') , so output should be
abc, 10, f100
abe, 20, f200
4)if (link like 'cb%') , so output should be
cbe, 3, f3
Any help in writing this group by query. I have a solution using CAST and string concat like below , but that seems to be in-efficient.
select link,number,fname from #temp
where link like 'ab%' and link+'_'+CAST(number AS varchar(255))
in (select link+'_'+CAST(MAX(number) AS varchar(255)) from #temp
group by link)
Thanks..
Using a self join:
SELECT x.link,
x.number,
x.fname
FROM #temp x
JOIN (SELECT t.link,
MAX(t.number) AS max_number
FROM #temp t
GROUP BY t.link) y ON y.link = x.link
AND y.max_number = x.number
Using a CTE and ROW_NUMBER (SQL Server 2005+):
WITH cte AS (
SELECT x.link,
x.number,
x.fname,
ROW_NUMBER() OVER(PARTITION BY x.link
ORDER BY x.number DESC) rank
FROM #temp x)
SELECT c.link,
c.number,
c.fname
FROM cte c
WHERE c.rank = 1
