Closed 6 years ago.
i have many tables that contains same column i want to search for a value and return all the line for example
Tab1
col1 col2 col3
val1 val2 val3
val7 val8 val9
Tab2
col1 col2 col3
val4 val2 val5
i want the sql syntax that return if i search in my java code for val2 the two lines
Tab1
col1 col2 col3
val1 val2 val3
and
Tab2
col1 col2 col3
val4 val2 val5
thank you
You can try doing a UNION between two queries each of which selects the records you want:
SELECT col1, col2, col3, 'Tab1' AS table_name
FROM Tab1
WHERE col2 = 'val2'
UNION ALL
SELECT col1, col2, col3, 'Tab2'
FROM Tab2
WHERE col2 = 'val2'
If you want to search for val2 in any column, then you can use this:
SELECT col1, col2, col3, 'Tab1' AS table_name
FROM Tab1
WHERE col1 = 'val2' OR col2 = 'val2' OR col3 = 'val2'
UNION ALL
SELECT col1, col2, col3, 'Tab2'
FROM Tab2
WHERE col1 = 'val2' OR col2 = 'val2' OR col3 = 'val2'
you also can try sp_MSforeachtable and temporary table.
CREATE TABLE #tt(col1 INT,col2 INT,col3 int)
INSERT INTO #tt
EXEC sp_MSforeachtable 'select * from ? where col1=''1'' and OBJECT_ID(''?'') in (OBJECT_ID(''table1''),OBJECT_ID(''table1''),OBJECT_ID(''table1'')) '
SELECT * FROM #tt

Table1 have columns col1 , col2 ,col3 , col4 , col5
Table2 have columns col1 , col3 , col5
I want to insert rows from Table2 to Table1
But col2 , col4 should be NULL datatype after inserting into Table2
How can I do it in HIVE , Currently I am using Hortonworks 3.1 version
You just use insert . . . select:
insert into table1 (col1, col2, col3, col4, col5)
select col1, null, col3, null, col5
from table2;
I have a table like this ( SQL SERVER )
col1 col2 col3 col4 col5
1 Goerge A B ++
2 Alex B B aa
2 Alex B B ++
now the second and the third rows have almost same values except in col5. in this case i want to delete one of them ( i want to be able to decide wich row from both of them i wanna delete ) like the one with value ++ so the table should look like this :
col1 col2 col3 col4 col5
1 Goerge A B ++
2 Alex B B aa
How can that be achieved?
Use CTE with ROW_NUMBER() to find (and delete) your duplicates
WITH CTE_Dup AS
(
SELECT *
, ROW_NUMBER OVER() PARTITION BY (Col1, Col2, Col3, Col4 ORDER BY Col5) RN
-- change ORDER BY criteria to make sure row you want to keep is 1st
FROM YourTable
)
DELETE --Try SELECT * to check before actually deleting
FROM CTE_Dup WHERE RN>1
It is not at all clear the logic you want here for determining which row is a "duplicate" but this example should show you a pretty straight forward way of handling this kind of thing.
declare #Something table
(
col1 int
, col2 varchar(10)
, col3 char(1)
, col4 char(1)
, col5 char(2)
)
insert #Something
values
(1, 'Goerge', 'A', 'B', '++')
, (2, 'Alex', 'B', 'B', 'aa')
, (2, 'Alex', 'B', 'B', '++')
;
with SortedValues as
(
select *
, ROW_NUMBER() over (partition by col1 order by col5 desc) as RowNum
from #Something
)
delete SortedValues
where RowNum > 1
select *
from #Something
You can try the below query. I grouped the columns and get the count of that and handled the conditions in the WHERE clause.
Query execution with the given sample data:
DECLARE #TestTable TABLE (col1 INT, col2 VARCHAR (20), col3 VARCHAR (20), col4 VARCHAR (20), col5 VARCHAR (20));
INSERT INTO #TestTable (col1, col2, col3, col4, col5) VALUES
(1, 'Goerge', 'A', 'B', '++'),
(2, 'Alex', 'B', 'B', 'aa'),
(2, 'Alex', 'B', 'B', '++');
SELECT * INTO #tmpResults FROM (
SELECT col1, col2, col3, col4, col5,
COUNT(*) OVER (PARTITION BY col1, col2, col3, col4 ORDER BY col1 ) AS CCnt
FROM #TestTable
) a
SELECT col1, col2, col3, col4, col5 FROM #tmpResults WHERE Ccnt = 1 AND Col5 = '++'
UNION
SELECT col1, col2, col3, col4, col5 FROM #tmpResults WHERE Ccnt > 1 AND Col5 <> '++';
DROP TABLE #tmpResults
Output:
col1 col2 col3 col4 col5

I'm using Sql Server 2012. Consider the table schema to be,
create table A (col1 int, col2 int)
I'm trying to execute this query,
select col1, col2, col3, col4 from A
I get execution error as col3 and col4 are not in table.
But is there any way, these 2 columns can be displayed in result with NULL as value for every row, even though it's not available in the table?
Use an alias for each one of these 2 columns:
select col1, col2, null as col3, null as col4 from A
Try below select query..
select col1, col2, null as col3, null as col4 from A
Cast Null as desired data type:
select col1, col2, cast(null as int) as col3, cast(null as int) as col4 from A
I am trying to copy multiple records using one query using insert select from.
Insert into tab_A(colId, col1, col2, col3)
Select colId, col1, col2, col3 form tab_A
Where colId in ( 2,4,6)
Would it be possible to assign different colId for new entries? For example colid 2 should be replaced with 23, 4 with 24 and 6 with 25. How could I achieve it in a single query?
this would work
Insert into tab_A(colId, col1, col2, col3)
Select 23 , col1, col2, col3 form tab_A Where colId = 2 UNION ALL
Select 24 , col1, col2, col3 form tab_A Where colId = 4 UNION ALL
Select 25 , col1, col2, col3 form tab_A Where colId = 6
If you give some more info I could provide somthing more reusable. Should/is colId (be) an identity column?
EDIT
This would work in this very specialised case
Insert into tab_A(colId, col1, col2, col3)
Select ((colId - 4) * (-1)) + colId + 20 , col1, col2, col3
form tab_A Where colId IN (2, 4, 6)
The function newId = ((oldId - 4) * (-1)) + oldId + 20 is obviously specific to the stated problem.
EDIT2
I suspect somthing like this is more generic approach is appropriate.
DECLARE #MaxColID INT
BEGIN TRANSACTION
SELECT #MaxColID = MAX(ColID) FROM tab_A
INSERT tab_A(colId, col1, col2, col3)
SELECT row + #MaxColID, col1, col2, col3
FROM
(
SELECT ROW_NUMBER() OVER (ORDER BY ColID) row, col1, col2, col3
FROM tab_A WHERE colID IN (2, 4, 6)
)
COMMIT
EDIT 3
If you think EDIT 2 is actually what you want then you really want to make ColID an IDENTITY column, then you could do this.
INSERT tab_A (col1, col2, col3)
SELECT col1, col2, col3 FROM tab_A WHERE colId IN (2, 4, 6)
I dont see col4 or col6 in your query, but is this what you want:
Insert into tab_A(colId, col1, col2, col3)
Select colId, col1, 23, col3 form tab_A
Where colId in ( 2,4,6)
have you just tried adding the disired difference to colId -
In your case, since you need to replace 2 by 23, difference is 21.
Insert into tab_A(colId, col1, col2, col3)
Select colId+21, col1, col2, col3
form tab_A Where colId in ( 2,4,6)
Note: I missed the part, that the differnce is not consistent in your case.
The proposed solution will work only if difference is same
There are a few options:
Add the new ID column to the original table and populate it with the new values before you do this insert, selecting the new ID column instead of the old. This would be the tidiest solution I think.
Alternative - Modify the ID value on the insert based on a rule e.g.
INSERT INTO tab_A(colID, col1, col2, col3)
SELECT colId + 20, col1, col2, col3
FROM tab_A
WHERE colID IN(2,4,6)
Last resort - Process the insert sequentially with a cursor, modifying the ID value each time.
You could also write case in the select. when 2 then 23 or whatever value.
i've got 1 row with many columns:
col1|col2|col3|...
and i want to have 1 column with many rows, like that:
col1
col2
col3

UNPIVOT if you're using version 2005+

If SQL Server 2000 or lower...
How to rotate a table in SQL Server: http://support.microsoft.com/kb/175574
Take a look at UNPIVOT:
CREATE TABLE Table1 (col1 INT, col2 INT, col3 INT, col4 INT);
INSERT INTO Table1 (col1, col2, col3, col4) VALUES (1,2,3,4);
SELECT col, value FROM Table1
UNPIVOT (value FOR col IN (col1, col2, col3, col4)) AS unpvt
Result:
col value
col1 1
col2 2
col3 3
col4 4
If you don't want to know which value came from which column, only select value:
SELECT value FROM Table1
UNPIVOT (value FOR col IN (col1, col2, col3, col4)) AS unpvt
