i have a table named masterlist wherein the columns are :
name-----age------sex
andrew---19-------male
trisha---23------female
and i have also another table which is namelist that is linked to the masterlist table.. after i search for the record andrew in the table namelist..i updated andrew as 25 and sex is female..now i want reset andrew's record, same to the records that andrew has in the table masterlist..
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian
View 5 Replies View RelatedHi,
I'm new to SQL Server but not new to SQL because I used it with Oracle. I wonder if it is possible to do this kind of statement on SQL Server:
UPDATE TableX M
SET (M.column1, M.column2, M.column3)=
(SELECT T.column1, T.column2, G.column3)
FROM Table_Y T,
Table_Z G
WHERE join condition))
WHERE EXISTS (join condition for TableX)
Basically, I'd like to update multiple columns in one statement but for some reason I can not get it to work.
What would be the equivalent on SQL Server?
Thanks for the help,

I have a single update statement that updates the same column multipletimes in the same update statement. Basically i have a column thatlooks like .1.2.3.4. which are id references that need to be updatedwhen a group of items is copied. I can successfully do this withcursors, but am experimenting with a way to do it with a single updatestatement.I have verified that each row being returned to the Update statement(in an Update..From) is correct, but that after the first update to acolumn, the next row that does an update to that same row/column combois not using the updated data from the first update to that column.Does anybody know of a switch or setting that can make this work, or doI need to stick with the cursors?Schema detail:if exists( select * from sysobjects where id = object_id('dbo.ScheduleTask') and type = 'U')drop table dbo.ScheduleTaskgocreate table dbo.ScheduleTask (Id int not null identity(1,1),IdHierarchy varchar(200) not null,CopyTaskId int null,constraint PK_ScheduleTask primary key nonclustered (Id))goUpdate query:Update ScheduleTask SetScheduleTask.IdHierarchy = Replace(ScheduleTask.IdHierarchy, '.' +CAST(TaskCopyData.CopyTaskId as varchar) + '.', '.' +CAST(TaskCopyData.Id as varchar) + '.')FromScheduleTaskINNER JOIN ScheduleTask as TaskCopyData ONScheduleTask.CopyTaskId IS NOT NULL ANDTaskCopyData.CopyTaskId IS NOT NULL ANDcharindex('.' + CAST(TaskCopyData.CopyTaskId as varchar) + '.',ScheduleTask.IdHierarchy) > 0Query used to verify that data going into update is correct:selectScheduleTask.Id, TaskCopyData.Id, ScheduleTask.IdHierarchy, '.' +CAST(TaskCopyData.CopyTaskId as varchar) + '.', '.' +CAST(TaskCopyData.Id as varchar) + '.'FromScheduleTaskINNER JOIN ScheduleTask as TaskCopyData ONScheduleTask.CopyTaskId IS NOT NULL ANDTaskCopyData.CopyTaskId IS NOT NULL ANDcharindex('.' + CAST(TaskCopyData.CopyTaskId as varchar) + '.',ScheduleTask.IdHierarchy) > 0

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
I am attempting to run update statements within a SELECT CASE statement.
Select case x.field

UPDATE TABLE1
SET TABLE1.FIELD2 = 1
ELSE
UPDATE TABLE2
SET TABLE2.FIELD1 = 2

I get incorrect syntax near the keyword 'update'.
I need to update multiple columns in a table with multiple condition.
For example, this is my Query
update Table1
set weight= d.weight,
stateweight=d.stateweight,
overallweight=d.overallweight
from
(select * from table2)d
where table1.state=d.state and
table1.month=d.month and
table1.year=d.year
If table matches all the three column (State,month,year), it should update only weight column and if it matches(state ,year) it should update only the stateweight column and if it matches(year) it should update only the overallweight column
I can't write an update query for each condition separately because its a huge select
If I want to update 2 columns at 1 time with a where clause
like
update table a
set column1 = 8 and
set column2 = 9
where id = 10
I know you can't use the and statement, what is the correct syntax?

I would like to update the "SMiles" column based on the data in the "Dist" column. If the number in the "Dist" column is less than 250 then subtract 25 and multiply it by 1.15 the result should go in the "SMiles" column.

Hi,
I am writting a bit of SQL that takes data from one table then inserts it into another one. There is a field that can be any value (and is usually null), but when I insert the value in the new table then I want to execute:
IF table.field>0 then tabl2.field='400'. In other words for every row in the selection that has a field that is greater than 0 then '400' will be put into the new table.
I am not sure if the IF stamement can loop through a number of rows and execute depending on the value of a field in that row??
Thanks

I am trying to apply the logic from the following resource: URL....but cannot get it to work with my logic for some reason.For example, the following query:
;WITH CTE1 AS (SELECT CONVERT(VARCHAR, GETDATE(), 120) AS Col1),
CTE2 AS (SELECT CONVERT(VARCHAR, GETDATE(), 111) AS Col2)
SELECT CTE1.Col1,CTE2.Col2
FROM CTE1
CROSS JOIN CTE2
GO
Produces the following output:
Col1 | Col2
2014-05-08 10:55:54 | 2014/05/08
But, as soon as I try to do something else like:
;WITH CTE1 AS (SELECT COUNT(login) FROM userinfo AS Col1),
CTE2 AS (SELECT COUNT(login) FROM userinfo AS Col2)
SELECT CTE1.Col1,CTE2.Col2
FROM CTE1
CROSS JOIN CTE2
GO
I receive the following errors:
Msg 8155, Level 16, State 2, Line 1
No column name was specified for column 1 of 'CTE1'.
Msg 8155, Level 16, State 2, Line 2

I have a table which I need to obtain data from but am having a problem with select statement.
Specifically, I have a table that has multiple records for a particular hostName where the name of the host is either a shortname (say "Larry") or a long name (say "Larry's").
I need to display only the long names (NOT THE SHORT NAME records with the similar hostName).
Select winsHostName, len(winsHostName) from winsData where winsClientIPAddress IN (SELECT winsClientIPAddress from winsData Group By winsClientIPAddress Having count(winsClientIpAddress) > 1) Order by winsHostName
Which returns data
Name Length
ATVDDR 6 ATVDDR1 7
This is a s far as I can get but,
Now, I need to list all remaining table fields based on the Name with the longer length and this is where I run into trouble.
The output should read per below with the remaining table fields which I cannot seem to extract with nested select statement
Name IP Addr Location
ATVDDR1 1.1.1.1 2ndFloor
I tried adding another GROUP BY by this gets me no where because I do not need to execute another aggregate in select statement. Maybe I need to use INNER JOIN
Please advise any assistance.
Would it be possible to retrieve a "dynamically" named field from a table by using an input parameter?
For example, if a table has fields named Semester1, Semester2, Semester3, Semester4, and I was lazy and only wanted to create one stored procedure for all semesters could I do the following...
ALTER PROCEDURE u_sp_x
@semester int
AS
Select Semester@semester
From ThisTable
Just curious.

View 5 Replies View RelatedI am renovating an existing application and am converting the existing passwords into hashed values using SHA1. I know how to compute the hashed values as a byte array for each record. What I don't know how to do easily is update all of the records i a single call to the database.

UPDATE HashedPassword = someOtherValue WHERE UserID = 102;

This is more of a basic SQL question rather than anything specific for T-SQL, but I assume someone here can help me...
I have a problem with properly combining a lot of AND and ORs in a SELECT statement in a stored procedure in order to get the desired results. The problem is that I want to have all results that fullfill all of the supplied conditions: InstitutionCode, CollectionCode, ScientificName, Locality (unless they are null, hence 'coalesce') and the Parentid, that can be in one of eight columns.
SELECT * FROM QueryView WHERE InstitutionCode = COALESCE(@museum, InstitutionCode) AND CollectionCode = COALESCE(@collection, CollectionCode) AND ScientificName LIKE '%' + @binomen + '%' AND Locality LIKE '%' + @locality + '%' AND ParentID1 = COALESCE(@taxparent, ParentID3) OR ParentID2 = COALESCE(@taxparent, ParentID2) OR ParentID3 = COALESCE(@taxparent, ParentID3) OR ParentID4 = COALESCE(@taxparent, ParentID4) OR ParentID5 = COALESCE(@taxparent, ParentID5) OR ParentID6 = COALESCE(@taxparent, ParentID6) OR ParentID7 = COALESCE(@taxparent, ParentID7) OR ParentID8 = COALESCE(@taxparent, ParentID8)
The current construction, however, gives me all results that fullfill either on of the four conditions, or the parentid in one of the columns. putting parentheses around parentid part gives me zero query results. I understand that the ORs should be restricted to the parentids and not the rest, but putting parentheses around parentid part gives me zero query results.
Has anyone got a good tip to help me resolve this puzzle?
