Transact SQL :: Update Multiple Table Referencing New Table Data
Aug 4, 2015
I have a table called ADSCHL which contains the school_code as Primary key and other two table as
RGDEGR(common field as SCHOOl_code) and RGENRl( Original_school_code) which are refrencing the ADSCHL. if a school_code will be updated both the table RGDEGR (school_code) and RGERNL ( original_schoolcode) has to be updated as well. I have been provided a new data that i have imported to SQL server using SSIS with table name as TESTCEP which has a column name school_code. I have been assigned a task to update the old school_code vale ( ADSCHL) with new school_code ( TESTCEP) and make sure the changes happen across all 3 tables.
I tried using Merge Update function not sure if this is going to work.
Update dbo.ADSCHL
SET dbo.ADSCHL.SCHOOL_CODE = FD.SCHOOL_Code
FROM dbo.ADSCHL AD
INNER JOIN TESTCEP FD
ON AD.SCHOOL_NAME = FD.School_Name
ID Flag TestDate Value Comment 111 2 12/15/2014 7.5 null 222 2 Null 10 received
Matrix_Current table could have 1 or multiple rows as below.
ID Flag TestDate Value Comment 111 2 01/26/2015 7.9 111 2 02/23/2015 7.9 111 2 04/07/2015 6.8 222 1 null 8 test comment 1 222 3 null 9 test comment 2
When I run below update
UPDATE AM SET M.Flag = MC.Flag, M.TestDate = MC.TestDate, M.Value = MC.Value, M.comment = MC.Comment FROM dbo.Matrix M inner join dbo.Matrix_Current MC on M.ID = MC.ID
Matrix table has value below:
ID Flag TestDate Value Comment 111 2 01/26/2015 7.9 222 1 Null 8 test comment 1
I want to update Matrix table from all row from Matrix_Current, final table would like below:
ID Flag TestDate Value Comment 111 2 04/07/2015 6.8 222 3 Null 9 test comment 2
Now we have different packages for 4 tables data loading. These 4 packages will start at a time. Before going to load the data we have to make the Flag to 1 and after that we have to load it. Because of this we have written Update statement to update the Value to 1 in respective Package.
Now we are getting dead lock because we are using same table at a same time. Because we are updating different records.
ID INT PK Name VARCHAR RefID FK ID Name RefID 1 Test1 <NULL> 2 Test1a 1 3 Test1b 1 4 Test1b1 3 5 Test1b1a 4
CREATE TRIGGER Update_ID ON TableA INSTEAD OF UPDATE AS IF UPDATE(ID) BEGIN DECLARE @old_ID INT DECLARE @new_ID INT
SELECT @old_ID = ID FROM DELETED SELECT @new_ID = ID FROM INSERTED
UPDATE TableA SET ID = @new_ID WHERE ID = @old_ID
UPDATE TableA SET RefID = @new_ID WHERE RefID = @old_ID END
SPROC: UPDATE TableA SET ID=6 WHERE ID=2
RefID is the FK to ID ID is also the PK to another table and has the relationship use cascading Delete and Update.
Problem: "The UPDATE statement conflicted with the SAME TABLE REFERENCE constraint" This is referring to the first UPDATE of the Trigger. It was my understanding that Instead Of checks the constraints after it is all done yet it errs with the first Trigger UPDATE. I was expecting to overcome the self-reference constraint issue by using Instead Of and with the first Trigger UPDATE, change the ID(PK) and then change the RefID(FK) with the second Trigger UPDATE. Once that was done, it should have not had any constraint problems. Thoughts?
Each one of the tables listed below has a “CreateDateTime” and “UpdateDateTime” fields, I need to get yesterday changes, I can get any record where either CreateDateTime or UpdateDateTime is greater than midnight yesterday butI need to watch dates on all of the tables so I need to do atleast 10 date checks.
If any table shows an updated or created record, I need to gather ALL of the information for that customer. So, if my name didn’t change (SCUS table), but my email does (SEML table), I have to pull out both the SCUS and SEML tables (and the others, of course). So It may not be simple WHERE clause, How can I achieve this:
Can we push the data for the above query in a physical table and create index to make the query fast rather than using the same set tables multiple times
I would like to update the flag of the promotion ID should the promotion ID date range overlap with Promotion ID(All) Date Range. The general logic is as below.
Update TableName SET PromotionID Flag = 1 AND Reason = 'Overlap with row ID(Overlap row ID number)' Where EACH ROW(Except with Promotion ID ALL) Date Range Overlap with ROW(with promotion ID ALL) Date range
I have 2 tables which with one-many relation. Table B has three child records based on Table A. I want to update value in Table from one of the records in table B.
Right now I am thinking of creating 2 temp table importing values there but does not seem to work. Can someone please help thanks. Armoghan
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.
I'm trying to create an email report which gives a result of multiple results from multiple databases in a table format bt I'm trying to find out if there is a simple format I can use.Here is what I've done so far but I'm having troble getting into html and also with the database column:
I have one table that has unique id's associated with each row of information. I want to delete rows of information in one table that have a unique ID that references information in another table.
Here is a basic breakdown of what I am trying to do:
Table1 (the table where the rows need to be deleted from) Column_x (Holds the id that is unique to the various rows of data - User ID)
Table2 (Holds the user information & has the associated ID) Column_z (holds the User ID)
I tried this on a test set of tables and could not get it to work. What I am trying to do is skip all rows of Table1 that have ID's present in Table2, and delete the rows of ID's that are not present in Table2.
Code:
SELECT Column_z FROM dbo.Table2 DELETE FROM dbo.Table1 WHERE Column_z <> Column_x
This did not seem to do what I needed, it did not delete any rows at all.
I wanted it to delete all rows in Table1 that did not have a reference to a user ID that matched any ID's in Column_z of Table2
Then I tried another scenerio that I also needed to do:
Code:
SELECT Column_z, Column_a FROM dbo.Table2 DELETE FROM dbo.Table1 WHERE Column_z = Column_x AND Column_a='0'
'0' being the user id is inactive so I wanted to delete rows in Table1 and remove all references to users that were in an inactive status in Table2.
Neither one of the Queries wanted to work for me in the Query Analyzer when I ran them. It just said (0) rows affected.
I have two table i want to update one table using other table.query given below
--table 1
create table #temp_P (P_id int null, p_name varchar(50), h_id int)
--table 2
which is to be updated,check the p_name from above table( like 1 has same name like 4 so 1 will replace by 4) create table #temp_t (t_id int null, p_id varchar(50), r_id int)
I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?
Im trying to create an update statement which references two tables (join) and has a CASE clause attached. Not sure where im going wrong...
Using T-sql!!!
update import set import.gone = from import inner join stat ON stat.id = import.id CASE WHEN stat.A = import.field2 THEN import.gone = sec.A WHEN stat.B = import.field2 THEN import.gone = sec.B WHEN stat.C = import.field2 THEN import.gone = sec.C WHEN stat.D = import.field2 THEN import.gone = sec.D WHEN stat.E = import.field2 THEN import.gone = sec.E WHEN stat.F = import.field2 THEN import.gone = sec.F ELSE import.gone = null END
I want to insert the data from temp table to other table. Only condition is, it needs to sorted based on tool number and tool date. For example if we have ten records for tool number 1000, it should be order by tool number and then based on tool_dt. Both tables doesn't have any primary keys. Please find below my code. I removed all the unnecessary columns for simple understanding. INSERT INTO tool_summary (tool_nbr, tool_dt) select tool_nbr, tool_dt from #tool order by tool_nbr, tool_dt...But this query is not working as expected. Data is getting shuffled.
TABLE1 ID Roll Name Amount . . . . . . so on --------------------------------------- 1 2 Alex 500 2 5 Jones 600 3 2 Ales 400
and we have TABLE 2
ID Roll Name Amount . . . . . . . so on
In both the Tables ID Field is Identity Field and rest all the columns are identical in both the tables.I want to perform a query in such a way that SQL Should,
1) Remove all data from TABLE2 First 2) Select those records from TABLE1 where Roll = 2 3) Then, Insert the results to TABLE 2
So we should get the result similar to below:
ID Roll Name Amount . . . . . . . so on --------------------------------------- 1 2 Alex 500 3 2 Ales 400
I am trying to do a simple update in one sql table from another where a certain condition in both tables are met.I am missing something basic and have tried numerous posted examples, without success.Here is my code (that does not update) :
insert into [dbo].[tbl_FG_Alert_Count_All_Report] ([Date] ,[Count] ,[Rule Type]) SELECT TOP 10 [Date] ,[Count] ,[Rule Type] FROM [dbo].[tbl_FG_Alert_Count_All] where Count <>'0' and DATEDIFF(dy,date,GETDATE()) = 1 order by Date desc
When I ran this T-SQL statement in SSMS; I don't get any error and as expected, I can see new data in [dbo].
[tbl_FG_Alert_Count_All_Report] table.
Now I created one job with same T-SQL Statement. Job completes successfully with out giving any error message; But unfortunately I don't see any new data in [dbo].[tbl_FG_Alert_Count_All_Report] table. What would be the reason that I don't see new data when job completes successfully but I can see new data after executing same T-SQL statement in SSMS?
