Single column from Multiple tables SQL-SERVER 2014 Exprs - sql

I have a DB with 50 tables having the same structure (same column names, types) clustered Indexed on the Created Date column . Each of these tables have around ~ 100,000 rows and I need to pull all of them for some columns.
select * from customerNY
created date | Name | Age | Gender

select * from customerFL
created date | Name | Age | Gender

The above is an example of the tables in the DB. I need an SQL that runs quickly pulling all the data. Currently, I am using UNION ALL for this but it takes a lot of time for completing the report. Is there another way for this where I can pull in data without using UNION ALL such as
select Name, Age, Gender from [:customerNY:customerFL:]
Out of context: Can I pull in the table name in the result?
Thanks for any help. I've been putting my mind to this but I can't find a way to do it quicker.

This dynamic SQL approach should meet your criteria, it selects table names from the schema and creates a SELECT statement at runtime for it to execute, and to meet the criteria of the UNION ALL each SELECT statement is given a UNION ALL then I use STUFF to remove the first one.
DECLARE #SQL AS VarChar(MAX)
SET #SQL = ''
SELECT #SQL = #SQL + 'UNION ALL SELECT Name, Age, Gender FROM ' + TABLE_SCHEMA + '.[' + TABLE_NAME + ']' + CHAR(13)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME LIKE 'Customer%'
SELECT #SQL = STUFF(#SQL,1,10,'')
EXEC (#SQL)
However I do not recommend using this and you should do what people have suggested in the comments to restructure your data.

Memory Optimising the test tables below gave a 7x speed increase compared to the same data in regular tables. Samples are 50 tables of 100000 rows. Please only run this on a test server as it creates filegroups/tables etc.:
USE [master]
GO
ALTER DATABASE [myDB] ADD FILEGROUP [MemOptData] CONTAINS MEMORY_OPTIMIZED_DATA
GO
ALTER DATABASE [myDB] ADD FILE ( NAME = N'Mem', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\DATA' ) TO FILEGROUP [MemOptData] --Change Path for your version
Go
use [myDB]
go
set nocount on
declare #loop1 int = 1
declare #loop2 int = 1
declare #NoTables int = 50
declare #noRows int = 100000

set #sql = 'create table [MemCustomer' + cast(#loop1 as nvarchar(6)) + '] ([ID] [int] IDENTITY(1,1) NOT NULL,[Created Date] date, [Name] varchar(20), [Age] int, Gender char(1), CONSTRAINT [PK_Customer' + cast(#loop1 as nvarchar(6)) + '] PRIMARY KEY NONCLUSTERED

SQL pivot table1 into table2 without using dynamic SQL pivot or hardcode query

I have seen many questions and answers given about pivoting table with SQL, with dynamic SQL pivot or hard code query with CASE WHEN.
However is there any way I can pivot table without using those 2?
Table 1:
| col1 | col2 | col3 |
|--------|-------|--------|
| ABCD | 1 | XY123 |
| ABCD | 2 | RT789 |
| PQST | 3 | XY123 |
| PQST | 4 | RT789 |
Pivoting to
| col1 | ABCD | PQST |
|--------|-------|-------|
| XY123 | 1 | 3 |
| RT789 | 2 | 4 |
My idea was to retrieve the structure of the col with:
WITH
structure AS (
SELECT DISTINCT
col3 AS col1, col1 AS colName, col2 AS values
FROM table1 ori
)
and then extracting matched values of each cell with joins and storing them temporarily. At last JOIN again populating them in the output. However I am stuck after the above step. I can't use PIVOT and have to do this dynamically (i.e. can't use the method to hardcode each value with CASE WHEN)
How can I achieve this?
This is not as efficient (and not as easy to code) as a dynamic pivot. However, it is doable.
It does all need to be dynamic e.g., creating each SQL statement as a string and executing that.
The process involves
Determine the column names (store in a temporary table)
Creating the table with the first column only
Populating that first column
For each additional column name
Adding a column to the table (dynamically)
Populating that column with data
You haven't specified the database - I'll illustrate the following below using SQL Server/T-SQL.
The following are in this db<>fiddle so you can see what's going on.
CREATE TABLE #ColNames (ColNum int IDENTITY(1,1), ColName nvarchar(100), ColNametxt nvarchar(100));
INSERT INTO #ColNames (ColName, ColNametxt)
SELECT DISTINCT QUOTENAME(Col1), Col1
FROM table1;
This will populate the #ColNames table with the values 1, [ABCD], ABCD, 2, [PQST], PQST.
The next step is to create your output table - I'll call it #pvttable
CREATE TABLE #pvttable (col1 nvarchar(100) PRIMARY KEY);
INSERT INTO #pvttable (col1)
SELECT DISTINCT Col3
FROM table1;
This creates your table with 1 column (col1) with values XY123 and RT789).
The write your favorite loop (e.g., cursor, while loop). In each step
Get the next column name
Add the column to the table
Update that column with appropriate data
e.g., the following is an illustrative example with your data.
DECLARE #CustomSQL nvarchar(4000);
DECLARE #n int = 1;
DECLARE #ColName nvarchar(100);
DECLARE #ColNametxt nvarchar(100);
SELECT #ColName = ColName,
#ColNameTxt = ColNameTxt
FROM #ColNames
WHERE ColNum = #n;
WHILE #ColName IS NOT NULL
BEGIN
SET #CustomSQL = N'ALTER TABLE #pvttable ADD ' + #ColName + N' nvarchar(100);';
EXEC (#CustomSQL);
SET #CustomSQL =
N'UPDATE #pvttable SET ' + #Colname + N' = table1.col2'
+ N' FROM #pvttable INNER JOIN table1 ON #pvttable.col1 = table1.col3'
+ N' WHERE table1.col1 = N''' + #ColNametxt + N''';';
EXEC (#CustomSQL);
SET #n += 1;
SET #ColName = NULL;
SET #ColNametxt = NULL;
SELECT #ColName = ColName,
#ColNameTxt = ColNameTxt
FROM #ColNames
WHERE ColNum = #n;
END;
SELECT * FROM #pvttable;

Using Subqueries to Define Column Alias

I have two tables which I have simplified below for clarity. One stores data values while the other defines the units and type of data. Some tests have one result, others may have more (My actual table has results 1-10):
Table 'Tests':
ID Result1 Result2 TestType(FK to TestTypes Type)
---------- ------------ ----------- -----------
1001 50 29 1
1002 90.9 NULL 2
1003 12.4 NULL 2
1004 20.2 30 1
Table 'TestTypes':
Type TestName Result1Name Result1Unit Result2Name Result2Unit ..........
------- --------- ------------ ----------- ------------ -----------
1 Temp Calib. Temperature F Variance %
2 Clarity Turbidity CU NULL NULL
I would like to use the ResultXName as the column alias when I join the two tables. In other words, if a user wants to see all Type 1 'Temp Calib' tests, the data would be formatted as follows:
Temperature Variance
------------ -----------
50 F 10.1%
20.2 F 4.4%
Or if they look at Type 2, which only uses 1 result and should ignore the NULL:
Turbidity
----------
90.9 CU
12.4 CU
I have had some success in combining the two columns of the tables:
SELECT CONCAT(Result1, ' ', ISNULL(Result1Unit, ''))
FROM Tests
INNER JOIN TestTypes ON Tests.TestType = TestTypes.Type
But I cannot figure out how to use the TestName as the new column alias. This is what I've been trying using a subquery, but it seems subqueries are not allowed in the AS clause:
SELECT CONCAT(Result1, ' ', ISNULL(Result1Unit, '')) AS (SELECT TOP(1) Result1Name FROM TestTypes WHERE Type = 1)
FROM Tests
INNER JOIN TestTypes ON Tests.TestType = TestTypes.Type
Is there a different method I can use? Or do I need to restructure my data to achieve this? I am using MSSQL.
Yes, this can be fully automated by constructing a dynamic SQL string carefully. The key points in this solution and references is listed as follows.
Count the Result variables (section 1.)
Get the new column name of ResultXName by using sp_executesql with the output definition (section 2-1)
Append the clause for the new column (section 2-2)
N.B.1. Although a dynamic table schema is usually considered a bad design, sometimes people are simply ordered to do that. Therefore I do not question the adequacy of this requirement.
N.B.2. Mind the security problem of arbitrary string execution. Additional string filters may be required depending on your use case.

Find a value from all table columns

I am building a functionality that will filter a data on all column table.
Let's say I have this table:
-------------------------------------
| ID | NAME | Address | Remarks |
| 1 | Manny | Phil | Boxer-US |
| 2 | Timothy | US | Boxer |
| 3 | Floyd | US | Boxer |
| 4 | Maidana | US | Boxer |
| 5 | Marquez | MEX | Boxer |
-------------------------------------
I search for "US", it should give me IDs 1-4 since "US" exists in their columns.
I could have this to filter it:
SELECT ID FROM tbl_Boxers
WHERE ID LIKE '%US%' OR NAME LIKE '%US%' OR Address LIKE '%US%' OR Remarks LIKE '%US%'
But I'm trying to avoid a long WHERE clause here since in actual, I have around 15 columns to look at.
Is there any other way to minimize the where clause?
Please help.
Thanks
The way this is normally done is to make a 'Searchable Field' column where you concatinate all search columns into one field for searching.
So while that provides an easier overview and querying it adds some management of the data you need to be aware off on inserts and updates.
Also on its own - it's not an optimal way of searching, so if performance is important - then you should look to implement full text search.
So the question is where you want to have the 'overhead' and whether that functionality your building is going to be run often or just once in a while.
If it is the former, and performance is important - look to full text. If it is just a once-in-a-while query, then I'd properly just do the long WHERE clause myself to avoid adding more overhead on the maintenance of the data
Check the following solution. Here the query is generated dynamically based on the column names in your table.
This is applicable if the given table is a physical table. This solution wont work for temporary tables or table variables.
BEGIN TRAN
--Simulate your table structure
--Should be a physical table. Cannot be a temp table or a table variable
CREATE TABLE TableA
(
ID INT,
NAME VARCHAR(50),
ADDRESS VARCHAR(50),
REMARKS VARCHAR(50)
)
--Added values for testing
INSERT INTO TableA(ID, name , address ,remarks) VALUES(1,'Manny','Phil','Boxer-US')
INSERT INTO TableA(ID, name , address ,remarks) VALUES(2,'Timothy','US','Boxer')
INSERT INTO TableA(ID, name , address ,remarks) VALUES(3,'Floyd','US','Boxer')
INSERT INTO TableA(ID, name , address ,remarks) VALUES(4,'Maidana','US','Boxer')
INSERT INTO TableA(ID, name , address ,remarks) VALUES(5,'Marquez',' MEX','Boxer')
--Solution Starts from here
DECLARE #YourSearchValue VARCHAR(50)--Will be passed
SET #YourSearchValue = 'US' --Simulated passed value
CREATE TABLE #TableCols
(
ID INT IDENTITY(1,1),
COLUMN_NAME VARCHAR(1000)
)
INSERT INTO #TableCols
(COLUMN_NAME)
SELECT COLUMN_NAME
FROM information_schema.columns
WHERE table_name = 'TableA';
DECLARE #STARTCOUNT INT, #MAXCOUNT INT, #COL_NAME VARCHAR(1000), #QUERY VARCHAR(8000), #SUBQUERY VARCHAR(8000)
SELECT #STARTCOUNT = 1, #MAXCOUNT = MAX(ID) FROM #TableCols;
SELECT #QUERY = '', #SUBQUERY = ''
WHILE(#STARTCOUNT <= #MAXCOUNT)
BEGIN
SELECT #COL_NAME = COLUMN_NAME FROM #TableCols WHERE ID = #STARTCOUNT;
SET #SUBQUERY = #SUBQUERY + ' CONVERT(VARCHAR(50), ' + #COL_NAME + ') LIKE ''%' + #YourSearchValue + '%''' + ' OR ';
SET #STARTCOUNT = #STARTCOUNT + 1
END
SET #SUBQUERY = LEFT(#SUBQUERY, LEN(#SUBQUERY) - 3);
SET #QUERY = 'SELECT * FROM TableA WHERE 1 = 1 AND (' + #SUBQUERY + ')'
--PRINT (#QUERY);
EXEC (#QUERY);
ROLLBACK
Hope this helps.

merge two rows in return query as one

I have a query that returns the people in a certain household, however the individuals show up in to separate rows, what i want to do is merge the two rows into one.
SELECT dbo.households.id, dbo.individuals.firstname, dbo.individuals.lastname
FROM dbo.households INNER JOIN
dbo.individuals ON dbo.households.id = dbo.individuals.householdID
WHERE (dbo.households.id = 10017)
Current results:
ID | First Name | Last Name |
1 | Test | Test1 |
1 | ABC | ABC1 |
Desired results:
ID | First Name | Last Name |ID1| First Name1| Last Name1|
1 | Test | Test1 |1 | ABC | ABC1 |
However if theres 3 people then it would need to merge all 3 and so on
Depending on the response to the question I asked above, below is a simple script that would compile the names into a string and then output the string (I don't have access to the syntax validator now so forgive any errors):
DECLARE
#CNT INT,
#R_MAX INT,
#H_ID INT,
#R_FIRST VARCHAR(250),
#R_LAST VARCHAR(250),
#R_NAMES VARCHAR(MAX)
SET #CNT = 0; --Counter
SET #R_NAMES = 'Names: ';
SELECT #R_MAX = COUNT(*) FROM dbo.individuals a WHERE a.householdID = #H_ID; --Get total number of individuals
PRINT(#R_MAX); --Output # of matching rows
--Loop through table to get individuals
WHILE #CNT < #R_MAX
BEGIN
--Select statement
SELECT * FROM (SELECT
#R_FIRST = b.firstname,
#R_LAST = b.lastname,
ROW_NUMBER() OVER (ORDER BY b.lastname, b.firstname) AS Row
FROM
dbo.households a INNER JOIN
dbo.individuals b ON a.id = b.householdID
WHERE
(a.id = #H_ID)) AS RN WHERE (Row = #CNT);
SET #R_NAMES = #R_NAMES + #R_FIRST + #R_LAST + '; '; --Add individual's name to name string
PRINT(CAST(#CNT AS VARCHAR) + ':' + #R_NAMES);
SET #CNT = #CNT +1; --Increase counter
END
PRINT(#R_NAMES); --Output the individuals
Provided you're using SQL Server 2005 or up, you might be able to use FOR XML PATH('') to concatenate the strings.
This should do what you want without having to do manual loops:
edit: fixed up SQL to actually work (now I have access to SQL)
SELECT households.id,
STUFF(
(
SELECT '; ' + [firstname] + '|' + lastname AS [text()]
FROM individuals
WHERE individuals.householdID = households.id
FOR XML PATH('')
)
, 1, 2, '' ) -- remove the first '; ' from the string
AS [name]
FROM dbo.households
WHERE (households.id = 10017)
This is pretty close to the format of data that you wanted.
it converts the data to XML (without any actual XML markup due to the PATH('')) and then joins it back to the header row.

Count number of rows across multiple tables in one query

I have a SQL Server 2005 database that stores data for multiple users. Each table that contains user-owned data has a column called OwnerID that identifies the owner; most but not all tables have this column.
I want to be able to count number of rows 'owned' by a user in each table. In other words, I want a query that returns the names of each table that contains an OwnerID column, and counts the number of rows in each table that match a given OwnerID value.
I can return just the names of the matching tables using this query:
SELECT OBJECT_NAME(object_id) [Table] FROM sys.columns
WHERE name = 'OwnerID' ORDER BY OBJECT_NAME(object_id);
That query returns a list of table names like this:
+---------+
| Table |
+---------+
| Alpha |
| Beta |
| Gamma |
| ... |
+---------+
But is it possible to write a query that can also count the number of rows in each table that match a given OwnerID? ie:
+---------+------------+
| Table | RowCount |
+---------+------------+
| Alpha | 2042 |
| Beta | 49 |
| Gamma | 740 |
| ... | ... |
+---------+------------+
Note: The list of table names needs to be returned dynamically, it is not suitable to hard-code table names into this query.
Edit: the answer...
(I can't edit your answers yet but I can edit my own question so I'm putting it here...)
Damien_The_Unbeliever had essentially the correct answer, but SQL Server doesn't allow string concatenation in an exec statement so I had to set the query prior to the exec statement. The final query is as follows:
DECLARE #OwnerID int;
SET #OwnerID = 1;
DECLARE #ForEachSQL varchar(100);
SET #ForEachSQL = 'INSERT INTO #t(TableName,RowsOwned) SELECT ''?'', COUNT(*) FROM ? WHERE OwnerID = ' + CONVERT(varchar(11), #OwnerID);
CREATE TABLE #t(TableName sysname, RowsOwned int);
EXEC sp_MSforeachtable #ForEachSQL,
#whereAnd = 'AND o.id IN (SELECT id FROM syscolumns where name=''OwnerID'')';
SELECT * FROM #t ORDER BY TableName;
DROP TABLE #t;
You can use sp_MSForeachtable, and the #whereand parameter, to specify a filter so you're only working against tables with an OwnerID column. Create a temp table, and populate that for each matching table. Something like:
create table #t(tablename sysname,Cnt int)
sp_MSforeachtable 'insert into #t(tablename,Cnt) select ''?'',COUNT(*) from ?',#whereAnd='and o.id in (select id from syscolumns where name=''OwnerID'')'
select * from #t
Two major caveats to mention - first is that sp_MSforeachtable is "undocumented", so you use it at your own risk - it could be suddenly removed from SQL Server by any kind of servicing, or in the next release.
The second is that, having a dynamic schema is usually a sign that something else has gone wrong in modelling - possibly attribute splitting (where sales for January and February are given different tables, even though they're logically the same thing and should appear in the same table, with possibly an additional column to distinguish them)
And, of course, you wanted to filter based on a particular clientID, so the query would be more like:
'insert into #t(tablename,Cnt) select ''?'',COUNT(*) from ? where OwnerID=' + #OwnerID
(Assuming #OwnerID is the owner sought, and is an int)
This would get the info from sysindexes. It can be slightly out of date but will give you a rough count
SELECT
[TableName] = so.name,
[RowCount] = MAX(si.rows)
FROM
sysobjects so,
sysindexes si
WHERE
so.xtype = 'U'
AND
si.id = OBJECT_ID(so.name)
GROUP BY
so.name
ORDER BY
2 DESC
If you needed it to be 100% right then you could use the undocumented feature sp_MSForEachTable
DECLARE #SQL VARCHAR(255)
SET #SQL = 'DBCC UPDATEUSAGE (' + DB_NAME() + ')'
EXEC(#SQL)
CREATE TABLE #foo
(
tablename VARCHAR(255),
rc INT
)
INSERT #foo
EXEC sp_msForEachTable
'SELECT PARSENAME(''?'', 1),
COUNT(*) FROM ?'
SELECT tablename, rc
FROM #foo
ORDER BY rc DESC
DROP TABLE #foo
You can use this:
DECLARE #nSQL NVARCHAR(MAX)
SELECT #nSQL = COALESCE(#nSQL + 'UNION ALL ' + CHAR(10), '')
+ 'SELECT ''' + TABLE_NAME + ''' AS TableName, COUNT(*) FROM ' + QUOTENAME(TABLE_NAME) + CHAR(10)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME = 'strKey'
-- This will PRINT out the dynamically generated SQL statement. Just replace this with EXECUTE(#nSQL) when you are happy to run it.
PRINT #nSQL
Update: To search for a specific OwnerId:
DECLARE #nSQL NVARCHAR(MAX)
DECLARE #OwnerId INTEGER
SET #OwnerId = 1
SELECT #nSQL = COALESCE(#nSQL + 'UNION ALL ' + CHAR(10), '')
+ 'SELECT ''' + TABLE_NAME + ''' AS TableName, COUNT(*) FROM ' + QUOTENAME(TABLE_NAME) + ' WHERE OwnerId = #OwnerId' + CHAR(10)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME = 'strKey'
EXECUTE sp_executesql #nSQL, '#OwnerId INTEGER', #OwnerId
SELECT
O.ID,
O.NAME,
I.ROWCNT
FROM SYSOBJECTS O
INNER JOIN SYSINDEXES I
ON O.ID = I.ID
WHERE O.UID = 5
AND O.XTYPE = 'U'
AND I.STATUS = 0
Try using this query it will give you id of the table, table name and no of rows for that table.
UID = 5 means I want to check in particular schema which has id = 5.You can check schema id using SELECT SCHEMA_ID('<schema name>');
XTYPE = 'U' means User defined tables only.
