Transact SQL :: How To Update Subsequent Columns If Proceeding Column Is Not Null
Jul 7, 2015
I've got a table with 6 fields :
EmployeeAccess
(MasterID, LoginID, AccessID, Storage1, Storage2, Storage3)
that needs to be updated using the data in the following spreadsheet
NewEmployeeAccessData
(ID, MasterID, AccessID1, LoginID1)
There is a 1:1 relationship between the two tables..I'm trying to code a pair of update statements on the EmployeeAccess table (1 for LoginID, 1 for AccessID) with the following logic:
If LoginID is NULL, then Update LoginID with new LoginID1 value,
If LoginID is not null, and Storage1 is NULL then Update Storage1 with New LoginID1 values
If LoginID is not null, and Storage1 is not NULL and Storage2 is NULL then Update Storage2 with New LoginID1 values
etc etc...
The same applies when trying to populate the AccessID column
If AccessID is NULL, then Update AccessID with new AccessID1 value,
If AccessID is not null, and Storage1 is NULL then Update Storage1 with New AccessID1 values
If AccessID is not null, and Storage1 is not NULL and Storage2 is NULL then Update Storage2 with New AccessID1 values
etc etc.
I have no control over the schema of this table so I'm trying to work the logic on how to update the columns in my table only if the corresponding column data is NULL, else update the next non NULL Storage column.
I need to check Table1 by Table2 only on NOT NULL cells and if all of them in the row match do not return that row as the result. In this case it will be:
SELECT a.Server, a.Databases, a.Users, a.Names FROM Table1 EXCEPT SELECT ISNULL(b.Server,c.Server), ISNULL(b.Databases,c.Databases), ISNULL(b.Users,c.Users), ISNULL(b.Names,c.Names) FROM Table2 AS a, Table1 AS c
But for many rows (like 100 000) it takes ages to get results, any better way to work on this?
I want to update the NewVol1 and NewVol2 in table #Rec2 from NewVol1 and NewVol2 of table #Rec1. It is some tricky because the value is NULL in some records of NewVol1 and NewVol2.
Update query. SAP, Code, Code1, Code2 and SAPdate are keyfield when join both table to update the NewVol1 and NewVol2 in table #Rec2 from NewVol1 and NewVol2 of table #Rec1.
Create table #Rec1 (SAP char(10), Code char(6), Code1 char(6), Code2 char(6), SAPDate datetime, NewVol1 char(20), NewVol2 char(20)) insert into #Rec1 values ('SATRIP','AAA','AA','A','2014-01-01','838.88484884',NULL) insert into #Rec1 values ('SATRIP','AAA','BB','B','2014-01-01','839.88484884',NULL) insert into #Rec1 values ('SATRIP','AAA','CC','C','2014-01-01','848.88484884',NULL) insert into #Rec1 values ('SATRIP','BBB','AA','A','2014-01-01',NULL,'383.48377373') insert into #Rec1 values ('SATRIP','BBB','BB','B','2014-01-01',NULL,'385.48377333') insert into #Rec1 values ('SATRIP','BBB','CC','C','2014-01-01',NULL,'675.48377234')

Hi,I have an updatable DataGrid linked to a SQLDataSource in a web site developed using VS2005. Update works fine unless a value in the existing row is Null. Only one column in the database allows nulls.Putting a debug stop in the SqlDataSource1_Updating event, I checked the parameter value in the Immediate window and got the following result:?e.Command.Parameters(16){System.Data.SqlClient.SqlParameter}System.Data.SqlClient.SqlParameter: {System.Data.SqlClient.SqlParameter}DbType: Int32 {11}Direction: Input {1}IsNullable: FalseParameterName: "@original_FiresolveJobNo"Size: 0SourceColumn: ""SourceColumnNullMapping: FalseSourceVersion: Current {512}Value: NothingIs there a property I can set to generate a suitable Null check clause for the Update statement?Many Thanks,Keith.
I have a table that has two columns. One column has ID from 1 to 1800. The other column is null. I want to update the second column with values from 29 to 43. So for ID 1, value will be 29, ID value will 30 and it goes to 43. Then after it will start from 29 again and goes to 43. It goes all the way to the highest ID, i.e. 1800.I have added a script for better clarity
I have 3 different companies that share the same ticket_types(CRMS System). I need to display the Ticket Types and the 3 company's Ticket Count:
Ticket Type | Company A Count | Company B Count | Company C Count
I can get the information individually for each company, but if a company doesn't have a ticket in one of the ticket_types, then it isn't displayed in a row. So, I tried to write the following, which isn't pulling back any data.
DECLARE @startdate date = '20150306' DECLARE @enddate date = '20151031' DECLARE @AcctGrp varchar(20) = '111' ;WITH TType AS ( SELECT ctp.description as TicketType
[Code] .....
If I run each SELECT individually from above (excluding the last SELECT), it works and I get the following:
TicketType AR Request Credit Availability/Rush Cancel Order Credit Card Payment Expedite Order Freight Quote
[Code] ...
How to get the query results? Am I even close to getting it right?
select CurrencyCode,TransactionCode,TransactionAmount,COUNT(TransactionCode) as [No. Of Trans] from TransactionDetails where CAST(CurrentTime as date)=CAST(GETDATE()as date) group by TransactionCode, CurrencyCode,TransactionAmount order by CurrencyCode
select CurrencyCode,TransactionCode,TransactionAmount,COUNT(TransactionCode) as [No. Of Trans] from TransactionDetails where CAST(CurrentTime as date)=CAST(GETDATE()as date) group by TransactionCode order by CurrencyCode
But of course this codes gives an error, but how can I get my desired result??
I'm wanting to create reports in SSDT 2012 which is connected to a 2008R2 database. I want to have parameters on for my reports where a user is able to select a year such as 2014. Unfortunate my table containing the data has two columns with a date value. the first is of the int type and contains an epoch formatted date. The second is a varchar type and shows the date as 2015-07-01 08:00:00. I would like to be able to write a query to return the year, monthnumber and daynumber from either of these columns.
I am trying to convert all columns to rows in sql, but giving an error.
SELECT Employee, Orders FROM (SELECT CisId, [Z_Id], [ModuleType] FROM CIS) p UNPIVOT (Orders FOR Employee IN (CisId, [Z_Id], [ModuleType]) )AS unpvt;
Error: The type of column "Z_Id" conflicts with the type of other columns specified in the UNPIVOT list.If I remove "Z_Id" from selection then giving same error for ModuleType also.
I have a Users Table. It is full of users already and I would like to start using the UserPIN in the software (this is an nvarchar column).
I would like to update the UserPIN column with the row_number. All of my efforts have resulted in setting the UserPIN to 1 for every record. I just want an update query that fill the UserPIN column in sequential order.
Hey ya'll... I need to create a query that I can run that will allow me to essentially take the first initial and last name and combine them from two columns in one table and update one column with that new data in another table. Example of need: UPDATE tblLogin.UserName with (first character(tblEmployee.FName)+(tblEmployee.LName)) WHERE tblLogin.EmployeeID = tblEmployee.EmployeeID. That was TOTALLY pseudo code and I know I'll need a join statement in there somewhere. Both tables reside on the same database, such as this: dbEMPLOYEE (Database)--> tblLogin (Table)----> UserName (Column)--> tblEmployee (Table)----> FName (Column)----> LName (Column) Any help would be GREATLY appreciated! Hopefully something soon - this was handed to me a few minutes ago and I have a few minutes to get it done.iSheahan
Hi,I have three columns and want to update the third column based on the comparison of first two columns in the same table.For instance:Col1 - val1, val2, val3, val4, val5......Col2 - NULL, NULL, val1, NULL, val2....Col3 - TRUE, TRUE, FALSE, FALSE, FALSE....Thanks for any help.
I have a simple question that is more about performance on my code for updating a column with the sum of two columns:
Example
Table = dbo.adding
c1 c2 c3Sum 1 2 3 5 4 6
Now if I just simple write
Update dbo.adding set c3SUM = c1 + c2
This works, but there is a null in c1 or c2 then I know I can write this:
if exists (select * from dbo.adding where c1 is NULL)
Update dbo.adding
set c1 = '0', c3SUM = '0' + c2 where c1 is NULL
if exists (select * from dbo.adding where c2 is NULL)
Update dbo.adding
set c2 = '0', equals = c1 + '0' where c2 is NULL
Update dbo.adding
set c3SUM = c1 + c2
This works as well, but I am not sure how perficient it is being that from my understanding the code will evaluate the table three times and update it based on the criteria. If the table consists of 100,000 rows then this might not be a good solution
Is there a more proficient way to do this... I personally try to as little coding as possible to help increase performance. I know I can make this very complex and declare variables and put everything in a loop, but I personally think that would be less profient..
ClaimNumTransactionDateUsername ClaimNum TransactionAmountUserName 2000074 20150209jerry.witt 2000074 -10000DATAFIX INSERTED ON 20150626 AT 162152493 LOCAL 2000074 20150626DATAFIX INSERTED ON 20150626 AT 162152493 LOCAL 2000074 -10000DATAFIX INSERTED ON 20150626 AT 162152493 LOCAL
[Code] .....
So,if we look at the result set, we notice 2 conditions where the IG_FinancialTransactionSummary.Username is like 'Data' and if we see the transaction date then sometimes that is the max transaction date or sometimes there are transactions that happened after but that doesn't have like '%data%' in username . So, i need to add a new column to my sql query which should basically verify if the username is like '%data%' and if that is the max(transaction date) or even if there are any transactions after that doesn't have like '%data%' then YES else No.
I upload data from a Txt File(Txt_Temp) where I have VinNumber with 6 digits. Another table name Resrve_Temp1 where I have Vinumber with 17 digit. Now I need to update the vinnumber 6 digit to 17 digit or to new column in Txt_temp.
Txt_Temp - Table
I tried this code with no succes and only one row is updating
update Txt_Temp Set Txt_Temp.Vinnumber=dbo.R_ResrvStock.Vin from dbo.R_ResrvStock inner join Txt_Temp on Right (dbo.R_ResrvStock.Vin,6)=Txt_Temp.VinNumber
OR Add this code in view
Select dbo.R_ResrvStock.Vin,R_Txt_Temp.Vinnumber,R_Txt_Te mp.Model_Code from dbo.R_ResrvStock inner join R_Txt_Temp on Right (dbo.R_ResrvStock.Vin,6)=R_Txt_Temp.VinNumber
I have a column with XML data stored in it. I need to update that column several times with new values for different nodes. I've written a CLR function to update the XML quickly but the update is always based on the initial value of the xmlData column. I was hoping that the subsequent updates would be based on the new data from the prior update (each xmlTable has several newData rows). Do I have to make this a table valued function and use cross apply?
UPDATE xmlTable SET xmlTable.xmlData = Underwriting.UpdateByDynamicValue(xmlTable.xmlData,newData.NodeID,newData.NewValue) FROM xmlTable JOIN newData ON xmlTable.ID = newData.fkXmlTableID
I have a table with ~30M records. I'm trying to add a column to the existing table with default value and have noticed following ... When using alter with default value- (Executes more than 45 min and killed forcefully)
ex: ALTER TABLE dbo.Table_X Add is_Active BIT CONSTRAINT DF_Table_X_is_Active DEFAULT 'FALSE' NOT NULL GO
When using update command after adding column with alter (without default value) it completes is 5 min.
ex: ALTER TABLE dbo.Table_X Add is_Active BIT NULL GO UPDATE Table_X SET is_Active = 0 WHERE is_Active IS NULL GO
Why there is so much of difference in execution times ? I was just trying to understand internal behavior of the SQL in these two scenarios.
My current proc updates(updates using joins of two or three tables) millions of records as per the condition provided for each department.
However, when the proc fails it writes to a ErrorTable, ERROR_MESSAGE(), ERROR_SEVERITY() and which department has failed.
Since the records are updated keeping the selected departments in loop, I get the department in a temp variable.Now, I was asked to log the specific record where the failure was occured.Something like log the identity column value or primary key value which record has failed.
I am dynamically creating a job using sql script and it does work fine(It creates the job and when it's done it gets deleted as it's created dynamically. so I won't be having any job history at all in the system.). I want to update an existing table if the jobs fails and I am not sure how I can do that using t-sql script. Is that possible?I have an idea but not sure whether it works. In the job create script, can I include the code for if the job fails then go to step 2 and update the table column with the error??? If so, how can I retrieve the error???
For our ETL process, we maintain a TransformationList table that has the source view and the destination table. Data is copied from the view into the table (INSERT INTO). I am trying to find column names in the Views that are not column names in the associated Table.
In the below example, want to end up with three records:
I have it almost working, except that there is a table, ChangeColPrefix table, that is used by the ETL process to change some of the view's column name prefixes. Some of the source views have column names with prefixes that do not match the destination table column names. Say view SouthBase has all the column names prefixed with SB - like SBAcct, SBName. And the Destination table of Area District has ADAcct, ADName. There would be a row in the ChangeColPrefix for SouthBase, SB, AD, 1, 2 that would be used by the ETL process to create the INSERT INTO Area District From SouthBase.
I need to use this ChangeColPreifx to find my unmatching columns between my source views and destination tables. With out that table SBAcct and SBName from SouthBase will not appear to match the columns of ADAcct and ADName, but they do match.
I want to end up with these three records as non-matching:
View1, Column4 View2, Column4 View2, Column5
View1 has Salumn2 and View2 has Salumn5, and they must be changed to Column2 and Column5 as per the ChangeColPrefix table before running the Select from INFORMATION_SCHEMA.COLUMNS EXCEPT Select from INFORMATION_SCHEMA.COLUMNS looking for unmatched columns.
/***** Set Up Test Data *****/ -- Create 2 test views IF EXISTS(SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[View1]')) DROP VIEW dbo.[View1] GO CREATE VIEW View1 AS SELECT '1' AS Column1 , '2' AS Salumn2 , '4' AS Column4;
