SQL Server 2012 :: Where Clause On Multiple Columns?
May 16, 2014
Right now I have to do something like this and it is time consuming every time I have to query a specific table...
WHERE (column5 = '1' OR column6 = '1' OR column7 = '1' OR column8 = '1' OR column9 = '1' OR column10 = '1' OR column11 = '1' OR column12 = '1')
Typing out the OR statement gets long, time consuming and prone to errors because that first where line with all the ORs can sometimes have 20+ ORs in it. As some insight, the columns are text columns, sometimes they have data, sometimes they are NULL. Sometimes they have the same data (i.e., column5 and column6 and column12 could both have '1' as values).
I concatenate multiple rows from one table in multiple columns like this:
--Create Table CREATE TABLE [Person].[Person_1]( [BusinessEntityID] [int] NOT NULL, [PersonType] [nchar](2) NOT NULL, [FirstName] [varchar](100) NOT NULL, CONSTRAINT [PK_Person_BusinessEntityID_1] PRIMARY KEY CLUSTERED
This works very well, but I want to concatenate more rows with different [PersonType]-Values in different columns and I don't like the overhead, of using the same table in every subquery ([Person_1]). Is there a more elegant way to do this, without using a temp table or something else?
I'm fairly new to SQL and am just setting up a Windows 8 app using an Azure SQL server. The issue I have is looking up a part number supersession and getting the latest number. One part number can have multiple supersessions (ie RTC5756 > STC8572 > STC3765 > STC9150 > STC9191 > SFP500160 ).The data I am supplied monthly has both the superseeded items and the supersession information in both columns and is not easy to decipher - for example:
The newest part number is kept in a separate table - called "source" - which in this instance is SFP500160. I need access to the latest part number but also to the part's previous numbers, due to the fact that some people may still be stocking them as an old part number and for them to search by. Is there an easy and efficient way of doing both a lookup for the supersessions and a join on the two tables to minimize the queries on the database?
Usually it is better to include the columns in the index that are in where clause, select list and join.I am thinking that the columns in the selected list is better to keep as index columns and the columns that are in the where clause is better to keep in key columns.Where do we use join column is it better to create as main key column or included column.
So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
Select Test_Name AS 'Test_Name', Table_Bird.Animal AS 'Birds', Table_Mammal.Animal AS 'Mammal', Table_Reptile.Animal AS 'Reptile, Table_Fish.Animal AS 'Fish' From Table_One
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.
TRANAMT being the amount paid & TOTBAL being the balance due per the NAMEID & RMPROPID specified.The other table includes a breakdown of the total balance, in a manner of speaking, by charge code (thru a SUM(OPENAMT) query of DISTINCT CHGCODE
Also with a remaining balance (per CHGCODE) column. Any alternative solution that would effectively split the TABLE1.TRANAMT up into the respective TABLE2.CHGCODE balances? Either way, I can't figure out how to word the queries.
I think I need to only create few if an index is covering all columns then I do not need to create more indexes for separate columns or should I create separate index as suggested?
CREATE INDEX [NCIX_20187_20186_TL_SRV_Stationary_Stock_Transact] ON [TL_SRV_Stationary_Stock_Transaction] ([SerialNo],[StationaryStatus]) GO CREATE INDEX [NCIX_20189_20188_TL_SRV_Stationary_Stock_Transact] ON [TL_SRV_Stationary_Stock_Transaction] ([StationaryStatus]) INCLUDE ([SerialNo]) GO
Should I create all indexes above or use minimum number of indexes which covers all columns as mentioned in above create index statements?
I would like to be able to combine the functionality of IN and LIKE in a WHERE clause. Although the simple AdventureWorks2012 example below illustrates the concept with 3 search criteria, the real-world example I need to apply the concept to has a couple dozen. This returns 50 rows, but requires multiple OR ... LIKE functions:
SELECT DISTINCT c.Name FROM Sales.Store c WHERE c.Name LIKE '% sports %' OR c.Name LIKE '% exercise %' OR c.Name LIKE '%toy%'
What I would like to do is something like this, which doesn't work:
SELECT DISTINCT c.Name FROM Sales.Store c WHERE c.Name IN(LIKE '% sports %', LIKE '% exercise %', LIKE '%toy%')
I could load up a cursor and loop through it, but the syntax is more cumbersome than the multiple LIKE statements, not to mention most SQL programmers are horrified at the mention of the abominable word 'cursor' for performance reasons.
A while back, a "quirky update" method was proposed for lightning fast running totals based on the three-part MSSQL UPDATE's SET statement and tally tables. However, some claimed this was not 100% absolutely guaranteed behavior.
How does the new OVER clause compare in terms of performance ?
DECLARE @Tbl TABLE ( pk int not null primary key identity, N int ) INSERT INTO @Tbl (N) SELECT TOP 1000 1 FROM syscolumns a CROSS JOIN syscolumns b SELECT pk, SUM(pk) OVER (ORDER BY pk ) FROM @Tbl
Because of the way in which a specific piece of code is written, I'm bound into using a WHERE clause for a report generation.Each Inspection generates a unique Inspection Number. Any re-inspection created from that inspection is assigned that Inspection Number and appended with ".A", ".B", ".C" and so on.
The problem is this: Each row's Primary Key is the "InspectionId" in "dbo.v_InspectionDetailsReports". I need to return not only the data related to that particular InspectionId, but also the data related to any previous related inspection. For example, if I have a main number of CCS-2012 and three re-inspections, CCS-2012.A, CCS-2012.B and CCS-2012.C, and I report on CCS-2012.B, I need all the data for CCS-2012, CCS-2012.A and CCS-2012.B but NOT CCS-2012.C.
I would prefer to not have to do everything in a WHERE statement, but my hands are a bit tied.
The "SELECT * FROM dbo.v_InspectionDetailsReports WHERE . . ." is already hardcoded (don't ask). SELECT * FROM dbo.v_InspectionDetailsReports WHERE ( RefOnly = 0 OR RefOnly IS NULL
I am using an aggregate with the OVER clause.Running the script is fast less than 1 second but when I say insert into a temp table the execution plan is very different at it take 8 seconds.I have attached the execution plans. Also the Statistics IO, Time messages. I am using SQL Server 2014 with backward compatibility to 2008 R2.
if (select OBJECT_ID('tempdb..#MM')) is not null drop table #MM CREATE TABLE #MM ([MyTableID] [int], [ParticipantID] [int], [ConferenceID] [nvarchar](50), [Points] [money], [DateCreated] [datetime], [StartPoints] [money], [EndPoints] [money], [LowPoints] [money], [HighPoints] [money]) insert into #MM ([MyTableID], [ParticipantID], [ConferenceID], [Points], [DateCreated], [StartPoints], [EndPoints], [LowPoints], [HighPoints]) selectmm.MyTableID, mm.ParticipantID, mm.ConferenceID, mm.Points, mm.DateCreated,
I have 10k indexes I need to rebuild and each time the script reaches an error it stops all further activity. How can I append 'GO' to the end of each line so it will continue on error messages?
Once I have the syntax I can do a find and replace function in Notepad++
USE [AdventureWorks2014] + char(13) + char(10) + GO ALTER INDEX [IX_Person] ON [Person].[Person] REBUILD PARTITION = ALL WITH (PAD_INDEX = OFF) + char(13) + char(10) + GO ALTER INDEX [IX_Emp] ON [HumanResources].[Employee] REBUILD PARTITION = ALL WITH (PAD_INDEX = OFF) + char(13) + char(10) + GO ************** Truncate ***********
How I am using a CASE statement within a WHERE clause to filter data:
CREATE PROCEDURE dbo.GetSomeStuff @filter1 varchar(100) = '', @filter2 varchar(100) = '' AS BEGIN SELECT
What I want, is to be able to pass in a single value to filter the table, or if I pass in (at the moment a blank) for no filter to be applied to the table.
Is this a good way to accomplish that, or is there a better way? Also, down the line I'm probably going to want to have multiple filter items for a single filter, what would be the best way to implement that?
the code below works (this is only a quick dumbed down version of the actual code, it might not work 100% for all cases). Is it at all possible to exploit the functions that were added to SSQL since v. 2005 to simplify this code ?
In SSRS, a parameter allows the user to create a list of invoices (from CRM) to be ordered in any of the following ways the user prefers:
'Document Date (most recent date first)' 'Document Number (highest number first)' 'Document Date (most recent first) and Number' 'Document Number (lowest number first)'
The invoices have a (supposedly) sequential identity-generated number. However Accounting may want to set a different date than the creation date on some invoices. So there is no way the invoice numbers will be in the same sequence as the invoice dates.
So I just created the "sorting fields" - they appear as junk in the output dataset (just do not drop them in the SSRS tablix - they have to be part of the SELECT statement to be usable in the ORDER BY clause.
The code is:
DECLARE @ls_OrderBy varchar(80) --'Document Number (highest number first)' --'Customer and Document Date (most recent date first)' --'Customer and Document Number (highest number first)' --'Document Date (most recent first) and Number'
I have a two tables each having a uniqueidentifier column person_id
I am trying to a select statement where I want a list of the person_id's in one table that are not in another table.
-- insert into wch_needed those who need checked
insert into #wch_needed (person_id, rendered_by ) select distinct e.person_id, e.rendered_by from #wch_who o, encounter e where o.person_id not in (select distinct person_id from #wch_have ) and o.person_id = e.person_id
the where conditional
where o.person_id not in (select distinct person_id from #wch_have )
I'm trying to write a query to select various columns from 3 tables. In the where clause I use a set of conditions, but most important condition is that I only want to see all results from the different columns where the ph.ProdHeaderDossierCode contains at least 25 lines of processed hours. I tried this with group by and having, but I constant get error messages on all other columns that I want to see: "is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause". How can I make this so I can see all information I need?
I want to create the following scenario. I have a table that stores employees working on projects and their project hours by week, but now I also need a running total per week for each of those projects. For example take a look below:
EmployeeID, Project, Sunday, Monday, Tuesday,....Saturday, ProjectHours, TotalProjectHoursPerWeek(this is the column I am trying to derive), FiscalWeek
