Relatively straight forward question but I am a novice with SQL queries. I'm trying to find in all the tables any record that contains a certain value.
So in a nutshell I want to find in the entire database any instance where the hContactId is 200.
I've tried the following:
USE dbname
SELECT *
FROM sys.Tables
WHERE hContacts.hContactId = 200;
I end up with
You have an error in your SQL syntax; check the manual that
corresponds to your MariaDB server version
I've seen some really complex queries like below that didn't work but surely there should be a way to query all tables for an integer right?
Another thing I tried to the same error message:
declare #sql varchar(8000), #tbl varchar(255), #col varchar(255),
#data varchar(50)
set #data = '200'
declare cur_tbl cursor for
select a.name, b.name from sysobjects a, syscolumns b, systypes c where a.id = b.id and a.type = 'U' and c.xtype = b.xtype and c.name in ( 'int' )
open cur_tbl
fetch next from cur_tbl into #tbl, #col
while ##fetch_status = 0
begin
set #sql = '
if exists (select * from [' + #tbl + '] where convert( varchar(255), [' + #col + '] ) = ''' + #data + ''')
select tbl=''' + #tbl + ''', col=''' + #col + ''', [' + #col + '], * from [' + #tbl + '] where convert( varchar(255), [' + #col + '] ) = ''' + #data + '''
'
exec(#sql)
fetch next from cur_tbl into #tbl, #col
end
close cur_tbl
deallocate cur_tbl
Again just looking for a basic query on all tables looking for those that match the hContactId. Any ideas?
Well you can always use a union:
SELECT * FROM Table_name_1
WHERE hContactId = 200;
UNION
SELECT * FROM Table_name_2
WHERE hContactId = 200;
UNION
SELECT * FROM Table_name_3
WHERE hContactId = 200;
I have the below code that works well but I don't want to continue typing in the dates daily.
My dates will always be the last 7 days (including today) - meaning that the table will be purged daily and the new data pull in daily.
select *
from
(
select EMP_ID, EMP_SHORT_NAME, SEG_CODE,
NOM_DATE
from sick_codes_Test$
) src
pivot
(
max(seg_code)
for nom_date in ([2018-07-14], [2018-07-15],[2018-07-16],[2018-07-17],[2018-07-18],
[2018-07-19], [2018-07-20])
) piv
So for "nom_date in" how can I make those dates the dates that will just be in the table?
I tried following along with the following link
https://www.mssqltips.com/sqlservertip/2783/script-to-create-dynamic-pivot-queries-in-sql-server/
But wasn't able to make it work
From following the above URL I came up with this code
DECLARE #columns NVARCHAR(MAX), #sql NVARCHAR(MAX);
SET #columns = N'';
SELECT #columns += N',' + QUOTENAME(NOM_DATE)
FROM sick_codes_Test$
SET #sql = N'
SELECT ' + STUFF(#columns, 1, 2, '') + '
FROM
(
SELECT EMP_ID, EMP_SHORT_NAME, SEG_CODE
from sick_codes_Test$
) AS j
PIVOT
(
max(seg_code) FOR nom_date IN ('
+ STUFF(REPLACE(#columns, ', [', ',['), 1, 1, '')
+ ')
) AS p;';
PRINT #sql;
EXEC sp_executesql #sql;
Any help would be greatly appreciated.
After more digging around I think I found a possible solution but after running the below I seeing the EMP_ID being duplicated.
DECLARE #DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE #ColumnName AS NVARCHAR(MAX)
--Get distinct values of the PIVOT Column
SELECT #ColumnName= ISNULL(#ColumnName + ',','')
+ QUOTENAME(NOM_DATE)
FROM (SELECT DISTINCT NOM_DATE FROM sick_codes_Test$ ) AS NOM_DATE
order by NOM_DATE ASC
--Prepare the PIVOT query using the dynamic
SET #DynamicPivotQuery =
N'SELECT EMP_ID, EMP_SHORT_NAME, ' + #ColumnName + '
FROM sick_codes_Test$
PIVOT(MAX(SEG_CODE)
FOR NOM_DATE IN (' + #ColumnName + ')) AS PVTTable'
--Execute the Dynamic Pivot Query
EXEC sp_executesql #DynamicPivotQuery
After more modifications I finally found a solution that worked
DECLARE #DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE #ColumnName AS NVARCHAR(MAX)
--Get distinct values of the PIVOT Column
SELECT #ColumnName= ISNULL(#ColumnName + ',','')
+ QUOTENAME(NOM_DATE)
FROM (SELECT DISTINCT NOM_DATE FROM sick_codes_Test$ ) AS NOM_DATE
order by NOM_DATE ASC
--Prepare the PIVOT query using the dynamic
SET #DynamicPivotQuery =
N'SELECT EMP_ID, EMP_SHORT_NAME, ' + #ColumnName + '
FROM (
SELECT DISTINCT EMP_ID,
EMP_SHORT_NAME,
SEG_CODE,
NOM_DATE
FROM sick_codes_Test$
)t

I am having difficulty formatting a string to be used with SP_executesql. I keep getting the following error:

I have a dynamic table with distinct values under ColumnName in below format and I'm not sure how to convert these rows to columns. Can anyone help?
ColumnName ColumnValue
AccountNumber 123456
AccountBalance 250
AccountState TX
AccountCity Houston
Target State
AccountNumber AccountBalance AccountState AccountCity
123456 250 TX Houston
You can use dynamic crosstab:
CREATE TABLE tbl(
ColumnName VARCHAR(20),
ColumnValue VARCHAR(20)
);
INSERT INTO tbl VALUES
('AccountNumber', '123456'),
('AccountBalance', '250'),
('AccountState', 'TX'),
('AccountCity', 'Houston');
DECLARE #sql NVARCHAR(MAX) = N'';
SELECT #sql =
'SELECT' + CHAR(10);
SELECT #sql = #sql +
' MAX(CASE WHEN ColumnName = ' +QUOTENAME(ColumnName, '''') + ' THEN ColumnValue END) AS ' + QUOTENAME(ColumnName) + ',' + CHAR(10)
FROM tbl;
SELECT #sql = SUBSTRING(#sql, 0, LEN(#sql) - 1);
SELECT #sql = #sql + CHAR(10)
+ 'FROM tbl'
PRINT #sql;
EXEC(#sql);
DROP TABLE tbl;
ONLINE DEMO
I'm looking for an efficient way to convert rows to columns in SQL server, I heard that PIVOT is not very fast, and I need to deal with lot of records.
This is my example:
-------------------------------
| Id | Value | ColumnName |
-------------------------------
| 1 | John | FirstName |
| 2 | 2.4 | Amount |
| 3 | ZH1E4A | PostalCode |
| 4 | Fork | LastName |
| 5 | 857685 | AccountNumber |
-------------------------------
This is my result:
---------------------------------------------------------------------
| FirstName |Amount| PostalCode | LastName | AccountNumber |
---------------------------------------------------------------------
| John | 2.4 | ZH1E4A | Fork | 857685 |
---------------------------------------------------------------------
How can I build the result?
There are several ways that you can transform data from multiple rows into columns.
Using PIVOT
In SQL Server you can use the PIVOT function to transform the data from rows to columns:
select Firstname, Amount, PostalCode, LastName, AccountNumber
from
(
select value, columnname
from yourtable
) d
pivot
(
max(value)
for columnname in (Firstname, Amount, PostalCode, LastName, AccountNumber)
) piv;
See Demo.
Pivot with unknown number of columnnames
If you have an unknown number of columnnames that you want to transpose, then you can use dynamic SQL:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(ColumnName)
from yourtable
group by ColumnName, id
order by id
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = N'SELECT ' + #cols + N' from
(
select value, ColumnName
from yourtable
) x
pivot
(
max(value)
for ColumnName in (' + #cols + N')
) p '
exec sp_executesql #query;
See Demo.
Using an aggregate function
If you do not want to use the PIVOT function, then you can use an aggregate function with a CASE expression:
select
max(case when columnname = 'FirstName' then value end) Firstname,
max(case when columnname = 'Amount' then value end) Amount,
max(case when columnname = 'PostalCode' then value end) PostalCode,
max(case when columnname = 'LastName' then value end) LastName,
max(case when columnname = 'AccountNumber' then value end) AccountNumber
from yourtable
See Demo.
Using multiple joins
This could also be completed using multiple joins, but you will need some column to associate each of the rows which you do not have in your sample data. But the basic syntax would be:
select fn.value as FirstName,
a.value as Amount,
pc.value as PostalCode,
ln.value as LastName,
an.value as AccountNumber
from yourtable fn
left join yourtable a
on fn.somecol = a.somecol
and a.columnname = 'Amount'
left join yourtable pc
on fn.somecol = pc.somecol
and pc.columnname = 'PostalCode'
left join yourtable ln
on fn.somecol = ln.somecol
and ln.columnname = 'LastName'
left join yourtable an
on fn.somecol = an.somecol
and an.columnname = 'AccountNumber'
where fn.columnname = 'Firstname'
This is rather a method than just a single script but gives you much more flexibility.

From executing the first query (by passing source DB and table name) you will get a pre-created execution query for the second SP, all you have to do is define is the column from your source:
+ Stable
+ Value (will be used to concentrate values based on that)
+ Dim (column you want to use to pivot by)
Names and datatypes will be defined automatically!
I cant recommend it for any production environments but does the job for adhoc BI requests.
I modified Taryn's answer ("Pivot with unknown number of columnnames" version) to show more than 1 row in the result. This requires to have an additional "Group" column

Please try

One more option which could be very useful is using CROSS APPLY

GO
