How to write the dynamically the below query?
Table
empid designation interestes
1 developer,tester cricket,chess
1 developer chess
1 techlead cricket
Condition:
IF empid = 1
AND (designation LIKE '%developer%' OR designationLIKE '%techlead%')
OR (interests LIKE '%cricket%').
How to write the above query dynamically if designations need to send more than 2,and also same on interstes .
please tell me ...
EDIT stored procedure code:
ALTER PROCEDURE [dbo].[usp_GetDevices]
#id INT,
#designation NVARCHAR (MAX)
AS
BEGIN
declare #idsplat varchar(MAX)
set #idsplat = #UserIds
create table #u1 (id1 varchar(MAX))
set #idsplat = 'insert #u1 select ' + replace(#idsplat, ',', ' union select ')
exec(#idsplat)
Select
id FROM dbo.DevicesList WHERE id=#id AND designation IN (select id1 from #u1)
END
Then when your form is submitted, create a string of designations (should really be a list of foreign keys if you have a 1 to many relationship) and pass that to the SQL. Then parse it into a table using one of many open-source SQL user functions:
-- #designations = 'developer,tester,techlead'
select text_val
from dbo.fn_ParseText2Table(#designations,',')
/* results:
text_val
--------
developer
tester
techlead
*/
Once you have the values in a table you can do any standard join or query operations.

There are multiple (mysql) databases running under 1 website. 1 database per registered account.
I'm looking for duplicate records in each contacts-table.
This is what i have for finding duplicates inside only 1 database:
SELECT COUNT(contacts.email), contacts.email, contacts.state, contacts.source,
FROM shard_40000006.contacts
LEFT JOIN shard_40000006.optin ON optin.email=contacts.email
GROUP BY contacts.email
HAVING COUNT(contacts.email) > 1;
The query i need searches for duplicates over shard_40000001, shard_40000002, shard_40000003, .. shard_40999999
You can use dynamic tsql.
declare #sqltext nvarchar(max) = N''
declare #parameter varchar(max) = 'define what you want to search here'
select #sqltext += '
SELECT COUNT(contacts.email), contacts.email, contacts.state, contacts.source,
FROM '+name+'.dbo.contacts
LEFT JOIN '+name+'.dbo.optin ON optin.email=contacts.email
GROUP BY contacts.email
HAVING COUNT(contacts.email) > 1'
FROM sys.databases
WHERE OBJECT_ID(QUOTENAME(name) + '.dbo.prac_nag', 'U') IS NOT NULL -- will return only if the table exists
print #sqltext
-- once your review the output, uncomment out below
--exec sp_executesql #sqltext
I just put refernce code. i didn't test this code.
Can anyone help me how to check duplicate values from multiple comma separated value. I have a customer table and in that one can insert multiple comma separated contact number and I want to check duplicate values from last five digits.For reference check screenshot attached and the required output is
contact_no. count
97359506775 -- 2
390558073039-- 1
904462511251-- 1
I would advise you to redesign your database schema, if possible. Your current database violates First Normal Form since your attribute values are not indivisible.
Create a table where id together with a single phone number constitutes a key, this constraint enforces that no duplicates occur.
I don't remember much but I will try to put the idea (it's something which I had used a long time ago):
Create a table value function which will take the id and phone number as input and then generate a table with id and phone numbers and return it.
Use this function in query passing id and phone number. The query is such that for each id you get as many rows as the phone numbers. CROSS APPLY/OUTER APPLY needs to be used.
Then you can check for the duplicates.
The function would be something like this:
CREATE FUNCTION udf_PhoneNumbers
(
#Id INT
,#Phone VARCHAR(300)
) RETURNS #PhonesTable TABLE(Id INT, Phone VARCHAR(50))
BEGIN
DECLARE #CommaIndex INT
DECLARE #CurrentPosition INT
DECLARE #StringLength INT
DECLARE #PhoneNumber VARCHAR(50)
SELECT #StringLength = LEN(#Phone)
SELECT #CommaIndex = -1
SELECT #CurrentPosition = 1
--index is 1 based
WHILE #CommaIndex < #StringLength AND #CommaIndex <> 0
BEGIN
SELECT #CommaIndex = CHARINDEX(',', #Phone, #CurrentPosition)
IF #CommaIndex <> 0
SELECT #PhoneNumber = SUBSTRING(#Phone, #CurrentPosition, #CommaIndex - #CurrentPosition)
ELSE
SELECT #PhoneNumber = SUBSTRING(#Phone, #CurrentPosition, #StringLength - #CurrentPosition + 1)
SELECT #CurrentPosition = #CommaIndex + 1
INSERT INTO #UsersTable VALUES(#Id, #PhoneNumber)
END
RETURN
END
Then run CROSS APPLY query:
SELECT
U.*
,UD.*
FROM yourtable U CROSS APPLY udf_PhoneNumbers(Userid, Phone) UD
This will give you the table on which you can run query to find duplicate.
How to INSERT into another table except specific field
e.g
TABLE A
ID(auto_inc) CODE NAME
1 001 TEST1
2 002 TEST2
I want to insert CODE and NAME to another table, in this case TABLE B but except ID because it is auto increment
Note: I don't want to use "INSERT INTO TABLE B SELECT CODE, NAME FROM TABLE A", because I have an existing table with around 50 fields and I don't want to write it one by one
Thanks for any suggests and replies
This can't be done without specifying the columns (excludes the primary key).
This question might help you. Copy data into another table
You can get all the columns using information_schema.columns:
select group_concat(column_name separator ', ')
from information_schema.columns c
where table_name = 'tableA' and
column_name <> 'id';
This gives you the list. Then past the list into your code. You can also use a prepared statement for this, but a prepared statement might be overkill.
If this is a one time thing?
If yes, do the insert into tableA (select * from table B)
then Alter the table to drop the column that your dont need.
I tried to copy from a table to another one with one extra field.
source table is TERRITORY_t
* the principle is to create a temp table identical to the source table, adjust column fields of the temp table and copy the content of the temp table to the destination table.
This is what I did:
create a temp table called TERRITORY_temp
generate SQL by running export
CREATE TABLE IF NOT EXISTS TERRITORY_temp (
Territory_Id int(11) NOT NULL,
Territory_Name varchar(50) COLLATE utf8_unicode_ci DEFAULT NULL,
PRIMARY KEY (Territory_Id)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
copy over with
INSERT INTO TERRITORY_temp (Territory_Id, Territory_Name) VALUES
(1, 'SouthEast'),
(2, 'SouthWest'),
(3, 'NorthEast'),
(4, 'NorthWest'),
(5, 'Central');
or
INSERT INTO TERRITORY_temp
SELECT * from TERRITORY_t
add the extra field(s) to match with the new table
copy from the temp table to the destination table
INSERT INTO TERRITORY_new
SELECT * from TERRITORY_temp
Please provide feedback.
Step 1. Create stored procedure
CREATE PROCEDURE CopyDataTable
#SourceTable varchar(255),
#TargetTable varchar(255),
#SourceFilter nvarchar(max) = ''
AS
BEGIN
SET NOCOUNT ON;
DECLARE #SourceColumns VARCHAR(MAX)=''
DECLARE #TargetColumns VARCHAR(MAX)=''
DECLARE #Query VARCHAR(MAX)=''
SELECT
#SourceColumns = ISNULL(#SourceColumns +',', '') + T.COLUMN_NAME
FROM
(
select name as COLUMN_NAME from sys.all_columns
where object_id = (select object_id from sys.tables where name = #SourceTable)
and is_identity = 0
)T
SELECT
#TargetColumns = ISNULL(#TargetColumns +',', '') + T.COLUMN_NAME
FROM
(
select name as COLUMN_NAME from sys.all_columns
where object_id = (select object_id from sys.tables where name = #TargetTable)
and is_identity = 0
)T
set #Query = 'INSERT INTO ' + #TargetTable + ' (' + SUBSTRING(#TargetColumns,2 , 9999) + ') SELECT ' + SUBSTRING(#SourceColumns,2 , 9999) + ' FROM ' + #SourceTable + ' ' + #SourceFilter;
PRINT #Query
--EXEC(#Query)
END
GO
Step 2. Run stored procedure
use YourDatabaseName
exec dbo.CopyDataTable 'SourceTable','TargetTable'
Explanations
a) dbo.CopyDataTable will transfer all data from SourceTable to TargetTable, except field with Identity
b) You can apply filter when call stored procedure, in order to transfer only row based on criteria
exec dbo.CopyDataTable 'SourceTable','TargetTable', 'WHERE FieldName=3'
exec dbo.CopyDataTable 'SourceTable','TargetTable', 'WHERE FieldName=''TextValue'''
c) Remove -- from --EXEC(#Query) WHEN finish
How to split a string in SQL Server.
Example:
Input string: stack over flow
Result:
stack
over
flow
if you can't use table value parameters, see: "Arrays and Lists in SQL Server 2008 Using Table-Valued Parameters" by Erland Sommarskog , then there are many ways to split string in SQL Server. This article covers the PROs and CONs of just about every method:
"Arrays and Lists in SQL Server 2005 and Beyond, When Table Value Parameters Do Not Cut it" by Erland Sommarskog
You need to create a split function. This is how a split function can be used:
SELECT
*
FROM YourTable y
INNER JOIN dbo.yourSplitFunction(#Parameter) s ON y.ID=s.Value
I prefer the number table approach to split a string in TSQL but there are numerous ways to split strings in SQL Server, see the previous link, which explains the PROs and CONs of each.
For the Numbers Table method to work, you need to do this one time table setup, which will create a table Numbers that contains rows from 1 to 10,000:
SELECT TOP 10000 IDENTITY(int,1,1) AS Number
INTO Numbers
FROM sys.objects s1
CROSS JOIN sys.objects s2
ALTER TABLE Numbers ADD CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number)
Once the Numbers table is set up, create this split function:
CREATE FUNCTION [dbo].[FN_ListToTable]
(
#SplitOn char(1) --REQUIRED, the character to split the #List string on
,#List varchar(8000)--REQUIRED, the list to split apart
)
RETURNS TABLE
AS
RETURN
(
----------------
--SINGLE QUERY-- --this will not return empty rows
----------------
SELECT
ListValue
FROM (SELECT
LTRIM(RTRIM(SUBSTRING(List2, number+1, CHARINDEX(#SplitOn, List2, number+1)-number - 1))) AS ListValue
FROM (
SELECT #SplitOn + #List + #SplitOn AS List2
) AS dt
INNER JOIN Numbers n ON n.Number < LEN(dt.List2)
WHERE SUBSTRING(List2, number, 1) = #SplitOn
) dt2
WHERE ListValue IS NOT NULL AND ListValue!=''
);
GO
You can now easily split a CSV string into a table and join on it:
select * from dbo.FN_ListToTable(' ','stack over flow')
OUTPUT:
ListValue
-------------------
stack
over
flow
(3 row(s) affected)
A common set-based solution to this kind of problem is to use a numbers table.
The following solution uses a simple recursive CTE to generate the numbers table on the fly - if you need to work with longer strings, this should be replaced with a static numbers table.
DECLARE #vch_string varchar(max)
DECLARE #chr_delim char(1)
SET #chr_delim = ' '
SET #vch_string = 'stack over flow'
;WITH nums_cte
AS
(
SELECT 1 AS n
UNION ALL
SELECT n+1 FROM nums_cte
WHERE n < len(#vch_string)
)
SELECT n - LEN(REPLACE(LEFT(s,n),#chr_delim,'')) + 1 AS pos
,SUBSTRING(s,n,CHARINDEX(#chr_delim, s + #chr_delim,n) -n) as ELEMENT
FROM (SELECT #vch_string as s) AS D
JOIN nums_cte
ON n <= LEN(s)
AND SUBSTRING(#chr_delim + s,n,1) = #chr_delim
OPTION (MAXRECURSION 0);
I know this question was for SQL Server 2008 but things evolve so starting with SQL Server 2016 you can do this
DECLARE #string varchar(100) = 'Richard, Mike, Mark'
SELECT value FROM string_split(#string, ',')
CREATE FUNCTION [dbo].[Split]
(
#List varchar(max),
#SplitOn nvarchar(5)
)
RETURNS #RtnValue table
(
Id int identity(1,1),
Value nvarchar(max)
)
AS
BEGIN
While (Charindex(#SplitOn,#List)>0)
Begin
Insert Into #RtnValue (value)
Select
Value = ltrim(rtrim(Substring(#List,1,Charindex(#SplitOn,#List)-1)))
Set #List = Substring(#List,Charindex(#SplitOn,#List)+len(#SplitOn),len(#List))
End
Insert Into #RtnValue (Value)
Select Value = ltrim(rtrim(#List))
Return
END
Create Above Function And Execute Belowe Query To Get Your Result.
Select * From Dbo.Split('Stack Over Flow',' ')
Suggestion : use delimiter for get split value. it's better. (for ex. 'Stack,Over,Flow')
Hard. Really hard - Strin Manipulation and SQL... BAD combination. C# / .NET for a stored procedure is a way, could return a table defined type (table) with one item per row.
