Transact SQL :: SELECT From Multiple Tables
Jul 13, 2015
I have the following two tables....
tblTimeEntry
-entryID
-entryDate
-entryUser
-entryJob
-entryTask
-entryWeekNo
tblWagesWeeks
-weekID
-weekDay
-date
I want to select all of the date and weekDay values from tblWagesWeeks for a specific weekID. I also want to show all entries fromtblTimeEntry for the weekID when a record exists. If data does not exist in fromtblTimeEntry I want to display a blank entry but still need weekDay and date from tblWagesWeeks.

I have a problem where my users complain that a select statement takes too long, at 90 seconds, to read 120 records out of a database.
The select statement reads from 9 tables three of which contain 1000000 records, the others contain between 100 and 250000 records.
I have checked that each column in the joins are indexed - they are (but some of them are clustered indexes, not unclustered).
I have run the SQL Profiler trace from the run of the query through the "Database Engine Tuning Advisor". That just suggested two statistics items which I added (no benefit) and two indexes for tables that are not involved at all in the query (I didn't add these).
I also ran the query through the Query window in SSMS with "Include Actual Execution Plan" enabled. This showed that all the execution time was being taken up by searches of the clustered indexes.
I have tried running the select with just three tables involved, and it completes fast. I added a fourth and it took 7 seconds. However there was no WHERE clause for the fourth table, so I got a cartesian product which might have explained the problem.
So my question is: Is it normal for such a type of read query to take 90 seconds to complete?
Is there anything I could do to speed it up.
Any other thoughts?
Thanks

I have database with three tables Accounts, Results, and ClosedOrders. All are connected through AccountID PK/FK.
I got a wonderful select statement that gives me the latest Results for each Account.
WITH cte AS
(
SELECT
Accounts.AccountID,
Accounts.AccountName,
Results.ResultTime AS LastUpdated,
[Code] ....
I've been struggling to extend this with two more columns from the ClosedOrders table. How to add columns to the this view? Basically what I need is this:
SELECT SUM([Lots]) AS Longs
FROM [DEV].[dbo].[ClosedOrders]
WHERE OrderTypeID = 0;
SELECT SUM([Lots]) AS Shorts
FROM [DEV].[dbo].[ClosedOrders]
WHERE OrderTypeID = 1;
But it has to "join" the CTE somehow so that I get the correct answer for each Account row.

I downloaded a day's worth of data into a single table first and named it as Full_Day_Data_Table.(10,000 records)
Later for some other purpose, downloaded the same day's data into five small tables.
Now when I compare the total row count of Full_Day_Data_Table vs Sum of row counts of five small tables, the row count does not match.
So, I would like to know the records that exists in Full_Day_Data_Table and not in small tables.

Is it possible to search a string/value across 1000's of tables and just display the table name and column name which it is in. I don't need to know every instance of the string/value only that I can find it in a given table name.

best way to go about this. My query works great and displays the information I require.
EG all demographic for ED, IP & OP. However if a patient has a record in each of the tables then I get the same info multiple times.
What I'm trying to do is a Select Distint against the entire query (below).
eg Select Distinct * from all below.
DECLARE @StartDate datetime = '01 oct 2015';
DECLARE @EndDate datetime = '30 OCT 2015';
--***OUTPATIENT DQ QUERY***--
SELECT distinct
HEYNo,
NHSNo2,
NHSNo1,

I have a number of tables, that I need to copy with data intact, about once a year.
Let's say the table name is 'dbo.MyTable'
I just do a SQL Statement like this:
SELECT * INTO dbo.MyTable'BU06032015 FROM dbo.MyTable
How can I automate this so that it does the Select Into statement and automatically adds the 'BU' + the current date?

I have three tables.
Table USERS Contains columns User_id and UserName
Table DOMAIN Contains columns Domain_id and DomainName
Table USER_DOMAIN Contains columns User_id, Domain_id, count, day, month, year
I am looking to run a report that pulls its information from USER_DOMAIN but instead of displaying User_id, Domain_id, it returns the UserName and DomainName associated.
The query to pull the info i need is very simple, where i am having problems is linking the user_id to the UserName and the Domain_id to the DomainName.

Hi all! I just registred (very nice site) and have problem with getting some data from multiple tables, I would like to get result in one result set and best would be in one sql query.
I have DB for miniMessenger proggy, what i try to do is retrieve list of contacts.
Table containing user account information.
CREATE TABLE `account` (
`id_account` mediumint(8) unsigned NOT NULL auto_increment,
`userdata_id` mediumint(8) unsigned NOT NULL default '0',
`login` varchar(15) NOT NULL default '',
`pwd` varchar(15) NOT NULL default '',

`ost_login` varchar(11) default NULL,
PRIMARY KEY (`id_account`),
UNIQUE KEY `messenger_UN` (`messenger_id`),
UNIQUE KEY `userdata_UN` (`userdata_id`)
)
INSERT INTO `account` VALUES (1, 1, 'User', 'fatimah', 4118394, 0, NULL);
INSERT INTO `account` VALUES (2, 2, 'Admin', 'haslo', 3333333, 0, NULL);
Contact list, first field is contact number (like 4356789 - MESSENGER id) next to this number is its contact number, auth - if contact was authorised, ban selfexplained :) I just take every row with number 4356789 and get contact numbers next to it.
CREATE TABLE `contacts` (
`contact_id` mediumint(8) unsigned NOT NULL default '0',
`contacts` mediumint(8) unsigned NOT NULL default '0',
`auth` tinyint(1) unsigned NOT NULL default '0',
`ban` tinyint(1) unsigned NOT NULL default '0',
KEY `Contacts ID` (`contact_id`)
)
INSERT INTO `contacts` VALUES (4118394, 3333333, 1, 0);
INSERT INTO `contacts` VALUES (4118394, 1234567, 0, 1);
Its table for messenger data, ID, status of contact (offline,online,ect), description, chat archiwum,
CREATE TABLE `messenger` (
`id_messenger` mediumint(8) unsigned NOT NULL default '0',
`status_id` tinyint(3) unsigned NOT NULL default '0',
`description` varchar(255) NOT NULL default '',
`archiwum` mediumtext NOT NULL,
PRIMARY KEY (`id_messenger`)
)
INSERT INTO `messenger` VALUES (1234567, 0, '', '');
INSERT INTO `messenger` VALUES (3333333, 1, '', '');
INSERT INTO `messenger` VALUES (4118394, 2, '', '');
Status is enumeration of status states(off,on,brb ect).
CREATE TABLE `status` (
`id_status` tinyint(3) unsigned NOT NULL default '0',
`stat` varchar(15) default NULL,
PRIMARY KEY (`id_status`)
)
INSERT INTO `status` VALUES (0, 'offline');
INSERT INTO `status` VALUES (1, 'Online');
INSERT INTO `status` VALUES (2, 'brb');
What i want to get is contact list + additional info of specific user by its messenger id. Like:
id_messenger,contacts,auth,ban,stat
which is userID, contact ID, authorisation, ban, status
My query looks like this:
SELECT id_messenger,contacts,auth,ban,status_id
FROM account,messenger,contacts
WHERE account.login = 'User'
AND messenger.id_messenger = account.messenger_id
AND contacts.contact_id = messenger.id_messenger
And it shows in stat only status of user of which i retrieve contact list. Please help me, im tired of working on this, im sure it is trivial :(

Can someone explain to me why this would be considered "bad"? One thing that pops in my mind is that I really don't need all the columns from all these tables, only specific columns. Would this cause a performance issue when used in a stored proc for a transactional app?
SELECT *
FROM CASE_XREF CX, CASE_RENEWAL_XREF CRX, RENEWAL_BATCH RB, PROPOSAL P
WHERERB.MKT_SEG = @MKT_SEG
AND RB.CORP_ENT_CD = 'oh'
AND RB.RENEWAL_DT = '01/01/2008'
AND CRX.TRIGGER_TYPE_CD = 'P'
AND RB.BATCH_ID = CRX.BATCH_ID
AND CRX.CASE_ID = CX.CASE_ID
AND CRX.REN_PROSPECT_ID = P.PROSPECT_ID
AND CRX.REN_PROP_NUM = P.PROP_NUM
AND P.PROP_STATUS <> 'C'

Basically I have 5 tables. These are...
1/ RCPCrossRef
2/ RCPPositionData
3/ RGCrossRef
4/ RGData
5/ RComments
------------------------------------------------------
RCPCrossRef and RCPPositionData are related by these keys:
RCPPositionData.UniquePositionID = RCPCrossRef.CPPositionID
RGCrossRef and RGData are related by these keys:
ON RGData.PositionID = RGCrossRef.GPositionID
-----------------------------------------------------------
RCPCrossRef and RGCrossRef are related by these keys:
ON RCPCrossRef.GMatchID = RGCrossRef.GMatchID
But RCPCrossRef may also contain a NULL value for this key meaning no relationship exists for that row.
----------------------------------------------------------------
Finally RComments is related to RCPCrossRef and RGCrossRef by these keys...
ON RComments.GPositionID = RGCrossRef.GPositionID
ON RComments.CPPositionID = RCPCrossRef.CPPositionID
But again, one of these columns in the RComments table could contain a NULL value meaning no relationship exists for that row of data.
---------------------------------------------------------------
So my aim is to display ALL DATA for each of these tables.
Tried the below but doesn't return any rows...
Code SnippetSELECT gd.Quantity, c.Comments,
gc.GPositionID, cc.CPPositionID, cd.PositionDate
FROM ReconComments AS c
INNER JOIN
RGCrossRef AS gc
INNER JOIN
RGData AS gd
ON gc.GPositionID = gd.PositionID
ON c.GPositionID = gc.GPositionID
INNER JOIN
RCPData AS cd
INNER JOIN
RCPCrossRef AS cc
ON cd.UniquePositionID = cc.CPPositionID
ON c.CPPositionID = cc.CPPositionID
WHERE gc.ForcedMatch = 'yes' AND cc.ForcedMatch = 'yes'
Thanks.

Hi,
I have a 'charges' table that records charges for an invoice. There are several different types of charges, each with its own unique set of additional data fields that need to be recorded.
I maintain separate tables for each charge type and these tables participate in an "ISA" relationship with the main charges table.
Here is a simplified version of my schema. Hourly charges are one type of charge:
charges table
=============
id int (autoincremented primary key)
date datetime
amount money
hourly_charges table
====================
charge_id int (primary key, also a foreign key to charges table)
start_time datetime
end_time datetime
I need to write a query that will duplicate all charges meeting a certain criteria by inserting new records into both the charges table and the hourly_charges table.
Here is some non-working pseudo-code that hopefully will get across what I would like to accomplish:
INSERT INTO charges JOIN hourly_charges
(
charges.date,
charges.amount,
hourly_charges.charge_id,
hourly_charges.start_time,
hourly_charges.end_time
)
SELECT
date,
amount,
SCOPE_IDENTITY(),
start_time,
end_time
FROM charges
JOIN hourly_charges
ON charges.id = hourly_charges.charge_id
WHERE some condition is true
Now I realize this code is invalid and I'll have to go about this an entirely different way but I'm wondering if someone can tell me what the proper way is.
Thanks,

I'm trying to get the number of records from one table where a column matches another column in a 2nd table. I then need the total values of another column that it has selected.
SELECT HOLIDAY_REF].holiday_id, COUNT([BOOKING].booking_status_id) AS record_count COUNT([BOOKING].total_value) AS total_value FROM [HOLIDAY_REF] LEFT OUTER JOIN [BOOKING] ON [HOLIDAY_REF].holiday_id = [BOOKING].booking_status_id WHERE [BOOKING].holiday_id=[HOLIDAY_REF].holiday_id && booking_status_id = '330'
Table 1 HOLIDAY_REF
holiday_id | holiday_name
1 | Italy
2 | Russia
3 | Spain
Table 2 BOOKING
holiday_id | booking_status_id | total_value
1 | 330 | 2500
3 | 330 | 1500
1 | 330 | 1750
2 | 330 | 1240
2 | 330 | 5600
Results would be:
Holiday_id | holiday_name | total_value | record_count
1 | Italy | 4250 | 2
2 | Russia | 6840 | 2
3 | Spain | 1500 | 1
Not sure I'm going about it the right way.

RComments is related to either RGData or RCPPositionData only.

SELECT * FROM Table1, Table2 WHERE Table1.ID IS NOT NULL AND Table2.ID IS NOT NULL
Basically I want to select all records from the two tables (they have the same fields, but are just different specialties) and then output them, but there is nothing in common between the two to reference one another, and it ends up in some kind of loop. Thanks. for the help.

Hi there,
I have a MS Access database (mdb) containing the following tables:
Crime
Criminal
CrimeCommitted
Hideout
CriminalType
The Criminal table contains information about each criminal and the CrimeCommitted table contains information about the specific crimes. I've written the following query to return only the latest crime committed by each criminal:
Code Snippet
SELECT Criminal.CriminalID, Criminal.Firstname, Criminal.Lastname, Criminal.Nickname, Criminal.Gender, Criminal.DOB, Criminal.Eyes, Criminal.Complexion, Criminal.Weight, Criminal.Height, Criminal.Build, Criminal.Scars, Criminal.Occupation, Criminal.CrimeOrgID, Criminal.IQ, Criminal.Hideout, Criminal.CriminalType, Max(CrimeComitted.Date) AS Last_Crime_Comitted
FROM Criminal INNER JOIN CrimeComitted ON Criminal.CriminalID=CrimeComitted.CriminalID
GROUP BY Criminal.CriminalID, Criminal.Firstname, Criminal.Lastname, Criminal.Nickname, Criminal.Gender, Criminal.DOB, Criminal.Eyes, Criminal.Complexion, Criminal.Weight, Criminal.Height, Criminal.Build, Criminal.Scars, Criminal.Occupation, Criminal.CrimeOrgID, Criminal.IQ, Criminal.Hideout, Criminal.CriminalType;
This query works fine for obtaining the Criminal table data, but once i've include CrimeCommitted.Country in the SELECT statement, the data returned contained all the crimes committed by each criminal (i just need the latest crime).
The query doesn't work when another table, other than Criminal, is selected. How can i obtain the columns in the CrimeCommitted table in this query?

I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:
I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.
1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B
If updated my query (see below) and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.
2. My second question: How to i get around this error?
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, fnSplitJson2(A.ITEM6,NULL) C
I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.
