SQL 2012 :: Using CASE In Order To Update Columns To Be Either A Or B
May 13, 2015
I am relatively new to complex queries and need creating a query using a CASE in order to update columns to be either A or B. A few things about this is that I am joining tables from linked servers as well. This is the last part. I execute the query and receive the error:
Incorrect syntax near the keyword 'from'.
select (select FirstName from [ZZZXXX].HCM.dbo.tPerson where PersonGUID = tPersonJobHistAlias.SupervisorPersonGUID) as supervisorFirstName,
(select LastName from [ZZZXXX].HCM.dbo.tPerson where PersonGUID = tPersonJobHistAlias.SupervisorPersonGUID) as supervisorLastName,
(select PersonID from [ZZZXXX].HCM.dbo.tPerson where PersonGUID = tPersonJobHistAlias.SupervisorPersonGUID) as SupervisorEmployeeID,
I'm unable to specify multiple columns in my order by statement if i use a case statement. Does anyone know why this is, or what syntax would make this work?
Thanks
SELECT .... ORDER BY (CASE Lower(@SortExpression) WHEN 'prodname' THEN prodname, prodprice WHEN 'prodsize' THEN prodsize, prodname WHEN 'prodprice' THEN prodprice, prodname Else prodcompany, prodname END)
I'm trying to set up a statement that gives me a field called 'BINNO' if the payor = Commercial. But, I have a few customers that don't have Commercial. They have a Payor of Grant or Part D. How would I set up a statement that looks for Commerical 1st...then Grant or Part D. I started with this
case when inscomp.payor = 'COMMERCIAL' then INSCOMP.BINNO
I have a stored proc that contains an update which utilizes a case statement to populate values in a particular column in a table, based on values found in other columns within the same table. The existing update looks like this (object names and values have been changed to protect the innocent):
UPDATE dbo.target_table set target_column = case when source_column_1= 'ABC'then 'XYZ' when source_column_2= '123'then 'PDQ'
[Code] ....
The powers that be would like to replace this case statement with some sort of table-driven structure, so that the mapping rules defined above can be maintained in the database by the business owner, rather than having it embedded in code and thus requiring developer intervention to perform changes/additions to the rules.
The rules defined in the case statement are in a pre-defined sequence which reflects the order of precedence in which the rules are to be applied (in other words, if a matching value in source_column_1 is found, this trumps a conflicting matching value in source_column_2, etc). A case statement handles this nicely, of course, because the case statement will stop when it finds the first "hit" amongst the WHEN clauses, testing each in the order in which they are coded in the proc logic.
What I'm struggling with is how to replicate this using a lookup table of some sort and joins from the target table to the lookup to replace the above case statement. I'm thinking that I would need a lookup table that has column name/value pairings, with a sequence number on each row that designates the row's placement in the precedence hierarchy. I'd then join to the lookup table somehow based on column names and values and return the match with the lowest sequence number, or something to that effect.
I have a table with 8 columns, I need to update data in multiple columns on this table, this table contains 1 million records, having single update was taking time so I broke the single update into multiple update statements and running multiple update statements in parallel, Each update statement updates different column.
This approach is working fine but I am getting the deadlock error.
Transaction (Process ID 65) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename] SET [No] = CASE WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa' ELSE 'Null' END
I want to compare two columns in the same table called start date and end date for one clientId.if clientId is having continuous refenceid and sartdate and enddate of reference that I don't need any caseopendate but if clientID has new reference id and it's start date is not continuous to its previous reference id then I need to set that start date as caseopendate.

It will be part of the stored proc, but for now I couldn't even get it running in ssms. It will be two parameters/variables, one for order by column name and other for order by direction, i.e. desc or asc.I have tried following three ways, but none is working:
(1) order by case when @Sort_by= '[A_ID]' AND @Sort_Dir ='Desc' then A_ID end desc case when @Sort_by= '[A_ID]' AND @Sort_Dir ='Asc' then A_ID end asc
(2) order by case when @Sort_by= '[A_ID]' AND @Sort_Dir ='Desc' then A_ID desc end case when @Sort_by= '[A_ID]' AND @Sort_Dir ='Asc' then A_ID asc end
(3) ORDER BY CASE @Sort_by when '[A_ID]' then [A_ID] end Case @Sort_Dir when 'Desc' then desc end
The query below at the bottom works, but when I try to add the line below (a third line/argument in the CASE statement) then I get an error. It is not possible to have a table name and a DESC (sort order) in the same CASE line/argument. Are there other ways to accomplish this, because I would like to sort with both "h.ObjectType" and "h.ObjectType DESC"? WHEN @SortBy = 2 THEN h.ObjectType DESC SELECT weight, ObjectText.ObjectId, ObjectText.ObjectType, ObjectText.Title, ObjectText.ShortText FROM @hits h INNER JOIN ObjectText ON h.id = ObjectText.ObjectId AND h.ObjectType = ObjectText.ObjectType WHERE ObjectText.LanguageCode = @LanguageCode ORDER BY CASE WHEN @SortBy = 0 THEN weight WHEN @SortBy = 1 THEN h.ObjectType END DESCRegards, Sigurd
I have a query which filters records containing uppercase andLowercase i.e.Smith and SMITH, Henderson and HENDERSON etc.Is there a way that I can filter only those records that contain thefirst uppercase letter and the remaining lowercase letters for myquery i.e. Smith , HENDERSON etc.Thanks
I have the following query in a user-defined function. It accepts a single string parameter, but for the sake of simplicity, I have substituted actual strings in the query. It basically checks the passed string. If it ends with "Id", it strips off the "Id" and returns the resulting string. If it ends with "Id" followed by a digit, it strips that off and returns the string.
SELECT CASE WHEN LEN('IncidentViolationId') > 2 AND RIGHT('IncidentViolationId', 2) = 'Id' THEN LEFT('IncidentViolationId', LEN('IncidentViolationId') - 2) WHEN PATINDEX('%Id[0-9]', 'IncidentViolationId') > 1 THEN LEFT('IncidentViolationId', PATINDEX('%Id[0-9]', 'IncidentViolationId') - 1) ELSE 'IncidentViolationId' END
This code has worked flawlessly for quite some time and all of a sudden I get "Invalid length parameter passed to left function". I understand why LEFT() would normally fail if I passed it a -1 for the second parameter, but in this scenario, asI understand it, it never should have reached the second WHEN condition since the first one evaluates to true. Why and why all of a sudden?
select col1, col2, col3, col4, col5,..... , (select col99 from tab2) as alias1 from tab1 where <condition> order by case @sortby when 'col1' then col1, when 'col2' then col2, when 'col3' then col3, when 'col99' then col99 end
when i execute the above query it gives me the following error message.
Server: Msg 207, Level 16, State 3, Line 1 Invalid column name 'col99'.
I have created a SQL Stored Procedure that uses a Case statement todetermine the Order By. For one of the Case statements I am trying toturn a Char field into Datetime in for the Order By, however I can notget it to work. Can someone please take a look and my code below andtell me what I am doing wrong. Thank you.ORDER BYCASE WHEN @SortBy = 'dttm_stamp' THEN dttm_stamp End,CASE WHEN @SortBy = 'Event_Date1' THEN CAST(CONVERT(char(10),Event_Date1,101) as datetime) End,CASE WHEN @SortBy = 'FullName' THEN Emp_lastname + ', ' +Emp_firstname End,CASE WHEN @SortBy = 'FullName Desc' THEN Emp_lastname + ', ' +Emp_firstname End DESC,CASE WHEN @SortBy = 'Emp_SSN' THEN Emp_SSN End
I have been trying to get the following Selects to work using a case expression in the order by section.
I know I can easily separate out the two statements but I want to do a select using the case statement below ; however, I keep getting error 16 --"Order by items must appear in the select list if the statement contains a union.
If remove the case statement and put order by "internalID desc" I receive no errors. Moreover, when I take out the union statement and execute the two select statements with each including the case expression it runs as planned.
Can anyone tell what the problem is here? I have combed the web looking for an answer, but it seems that the statement is valid.
Thanks J declare @date set @date = '2001'
select internalID from section_data_v3
union
select internalID from section_data_v4
order by case when (@date = '2001') then internalID end desc
I am trying to order by the field and direction as provided by input parameters @COLTOSORTBY and @DIR while using a CTE and assigning Row_Number, but am running into syntax errors.
Say I have a table called myTable with columns col1,col2,col3,
Here's what I'm trying to do
with myCTE AS ( Select col1 ,col2 ,col3 ,row_number() over (order by case when(@DIR = 'ASC') then
case when @COLTOSORTBY='col1' then col1 asc when @COLTOSORTBY='col2' then col2 asc else col3 asc end else
case when @COLTOSORTBY='col1' then col1 desc when @COLTOSORTBY='col2' then col2 desc else col3 desc end end from myTable )
Please let me know what i can do with minimal code repetition and achive my goal of dynamically sorting column and direction. I do not want to use dynamic SQL under any circumstance.
I am familiar with the ALTER TABLE syntax that can be used to add columns to an existing table, but the columns are appended to the end of the table. Enterprise Manager allows you to insert a column in the desired place in the table, but I suspect that behind the scenes it creates a temp table with the new structure, drops the old version of the table and renames the temp table to the orginal table name (I could be wrong on this).
Is there a way to insert a new column in a specific place in a table using SQL rather than EM?
Is there a dynamic management view or system procedure which I can use to find out what columns are in an index, what columns are as an INCLUDE in the index and whether or not the column(s) are ascending or descending. This is excluding the utilities I already know about below:
sys.indexes sys.index_columns sp_helpindex dm_db_index_physical_stats dm_db_index_operational_stats I only ask because it is a pain to look through the sys.indexes and sys.index_columns tables every time I want to know about what columns are in the index created. I also know that scripting the index would give me the information I need but there must be a better way.
Hi, I am using MS SQL Server 2005 9.00.1399.00. I am trying to make a PivotReport. Everything is fine, but the columns are are ordered alphabetically, but i want that they are ordered in a specific way. So i just created a new column ProcId in the Query, but how can i order the columns with the new column but display the other values.
and thats what gets written to the flatfile destination.
i want SSIS to preserve the column order and write it as col1,col2,col3,col4 instead of what is happening now and it gets written as col2,col4,col3....
i am running sql2k5 and SSIS with sp2
is this a bug is there a solution for this or change the order of the columns for the flat file destination
Hi Everyone, I am trying to do a query where I need to use as little C# as possible to build my gridview. Basically I have a column called statusID. There are about 15 options for this column but I only want to count certain ones. I want to count when statusID = 3 and output that into a column called "fullUnitsUsed" but when the value is 4 or > 13 I want it to count and put the result into a column called "halfUnitsUsed". I also want it to count based on the month. To accomplish this I have used CASE and GROUP BY. This has worked to some extent. Currently if I COUNT for one month I get the correct number of fullUnitsUsed and halfUnitsUsed used for January. Unfortunately the query returns 2 records for the month. The first one has a value for fullUnitsUsed and halfUnitsUsed is NULL, the second record has fullUnitsUsed as NULL and halfUnitsUsed has the correct value. I was hoping to output one record where both fullUnitsUsed and halfUnitsUsed have data. My other problem is that if I test for the entire year (which is what this query is supposed to do) there are 5 records returned for each month, 3 of the records have fullUnitsUsed and halfUnitsUsed both as NULL and for the other 2, one has fullUnitsUsed with data and the other has halfUnitsUsed with data and the other column in both records is NULL. The values for fullUnitsUsed and halfUnitsUsed are counted for the entire year as well, which I only want it to count based on each month. Below is my query, any suggestions about how to approach this will be greatly appreciated. If any clarification is needed please let me know. Again if I could get this to work completely with SQL and not need to use any more C# than I have to it would be preferable. SELECT People.lastName + ', ' + People.firstName AS fullName, Property.Name, NYSDDSORegion.Description, OpenDays.[month], OpenDays.maxOpenDays,CASE Attend.statusID WHEN 3 THEN COUNT(Attend.statusID) END AS fullUnitsUsed,CASE Attend.statusID WHEN 4 THEN COUNT(Attend.statusID) WHEN 14 THEN COUNT(Attend.statusID) WHEN 15 THEN COUNT(Attend.statusID) WHEN 16 THEN COUNT(Attend.statusID) WHEN 17 THEN COUNT(Attend.statusID) WHEN 18 THEN COUNT(Attend.statusID) WHEN 19 THEN COUNT(Attend.statusID) WHEN 20 THEN COUNT(Attend.statusID) END AS halfUnitsUsed FROM Attend INNER JOIN People ON Attend.personID = People.personID INNER JOIN Property ON Attend.propertyID = Property.propertyID INNER JOIN NYSDDSORegion ON Property.RegionID = NYSDDSORegion.RegionID CROSS JOIN OpenDays WHERE (Attend.attendDate BETWEEN '1/1/2007' AND '12/31/2007') GROUP BY Property.Name, People.lastName, NYSDDSORegion.Description, People.firstName, OpenDays.monthID, OpenDays.[month], OpenDays.maxOpenDays, Attend.statusID ORDER BY Property.Name, fullName, NYSDDSORegion.Description
I have a problem. I need to rename all columns of a database to uppercase. Since SQL SERVER 2005 does not support changing system tables is there a smooth way to do this? Has anyone ideas for a script? point me to the right direction. I have found the stored procedure sp_rename which could be useful (or would it be better to alter the tables)... So any help would be appriciated very much...
Is it possible to combine a CASE statement with two different columns to retrieve data into one result column? In one column it has multiple JobCode, but this needs to be divided. The only way I can see to do this is take the data from another column to get the results.Ex. JobCode - has one code for several job descriptions (there are about 30), but all within this code cannot have the same level of access. So I need to divide them out, and put them in one column for AccessLevel.
JobTitle - has one code for one job, (but there are over 100).I want to pull from both columns to get the results I need to assign appropriate access level in one column.
Case JobCode (they all have same job code, but everyone in this job code should not have same access) When '45' Then '1' (Principal, Asst. Prin, or any Administrator, Counselors) When '25' Then '2' (this could be teacher, etc. ) Case JobTitle (this is how access should be) When '12345' Then '1' (this is Administration only)
According to BOL, columns in an ORDER BY clause do not have to be in the SELECTcolumn list unless the SELECT includes DISTINCT, or the UNION operator.Is this a SQL Server thing, or SQL standard behavior? That is, if I were to writeabsolutely pure SQL-92, must columns in the ORDER BY clause be present in the SELECTlist?
