Updating A Column With A Count From Another Table?
May 18, 2014
My goal is to with one update statement, fill TABLE1.counter (currently empty) with the total count of TABLE2.e# (employee). Also, if TABLE1.e# isn't in TABLE2.e# then it sets it to "0" (TABLE1.e# 8 and 9 should have a counter of 0) This is for sqlplus.
e.g. TABLE2:
e#
--
1
2
3
4
5
5
6
7
7
1
2
3
4
5
UPDATE TABLE1
SET counter = (
SELECT COUNT(TABLE2.e#)
FROM TABLE2 INNER JOIN TABLE1 ON (TABLE2.e# = TABLE1.e#)
GROUP BY TABLE2.e#);
hi i want to update column with new value in a table is it possible to do so in stored procedure . the name of the column will be an input to stored procedure ie at the time of writing the stored procedure i dont know which column the user will be updating
Does anyone know of the SQL statement to add additional comuns to an existing table. I know i can do it through enterprise managaer, but I want to see if I can do it from query analyzer or some script to add columns without having to recreate the table. Or a way to save off the data and recreate the table then placing data back in? I hope that makes sense. I am thinking of this from the sens of doing all updates through source safe
I'm looking for some performance assistance on updating a column value in a table that contains approximately 50 million rows. I have a permanent table in another database that has the key column and value to be set. My query is listed below, but I'm afraid it will run quite awhile. Any suggestions would be appreciated.
update mytable set column2 = b.column2 from mytable as a join mytable1 as b on a.column1 = b.column1
There is a one to one relationship between the two tables.
One more question about this Custom Calendar table I'm creating. I have a column called "IsWorkdays" which indicates if the day represented by a row is a workday or not. For our purposes, I also need to create a row that accumulates those numbers by month. So, if it is the 3rd workday of the month, this column would have a 3. This is beyond my current T-SQL ability. Does anyone know how to do this?
I have a table for blog comments I want to add a column that counts the number of comments for each article. existing table looks like this: CommentID ArticleID (FK) commentAuthor authorEmail comment commentDate (getDate()) I would like to add a column that counts the number of total comments for each article.This will give me what I want using the VS query tool: "SELECT COUNT(comment) AS Expr1 FROM UserComments WHERE (articleid = @articleid)" But can I add that to the table somehow so it does it automagically???

Can somone tell me how to do that in SQL Server 2000? Thanks Khushbu

The boss has decided that the data from a table we have on one database (containing daily data) needs to be copied to a "history" table on a different database, on a different server.
The transfer will probably be done with a scheduled stored procedure, and all columns will be transferred EXCEPT for two columns in the source table, which are not present in the destination table. This means instead of an "INSERT Dest SELECT * FROM Source" I have to do an "INSERT Dest SELECT yada,yada,yada... FROM Source" in order to disregard the columns we don't care about. NO problem.
I was thinking (you should smell trouble - and sawdust burning at this point) that this leaves us open to a punch below the belt later when a new column is added to the Source table, since we are using a definitive list of columns to move rather than a *, and the new column could be added without the otherwise system-generated, *-sponsored "gentle reminder" that it also needs to be added to the Dest table. I'm not as convinced as The Boss that "Oh, I'm sure we'll remember to add it to the history table when that happens" :lol:
So, long story shorter (nah...too late for that) - I figure I can write a check at each day's historical transfer on the count of columns in one table verses the other, and send an email or fail the job if the count doesn't make sense.
For example, if the Source table has 34 columns, since we don't care about two of them, the Dest table should have 32 columns, if things are still in synch. OK, I think (insert burning sawdust smell here), I can use a SysObjects thang to count rows. BOL points out INFORMATION_SCHEMA.COLUMNS as a possibility.
Here is the code I think (sawdust) can be used:select ((select count(*) from SourceDb.INFORMATION_SCHEMA.columns where table_name = 'Source') - (select count(*) from HISTSERVER.DestDb.INFORMATION_SCHEMA.columns where table_name = 'Dest')) as ColumnDiff
Trouble is...this fails because apparently the INFORMATION_SCHEMA thang doesn't do well with remote servers.
Can anyone figure a way around this, or suggest an alternative? I'm still looking, but thought I'd also toss it out onto the board for your generous consideration.
Thanks - and can you BELIEVE the year is already 1/12th of the way OVER?!?!?! Paul

I'm hoping someone can help with with a task I've been given. I need to write a trigger which will act effectively as a method of automatically distributing of incoming call ticket records. See DDL below for creation of the Assignment table, which holds information on the call ticket workload.
SELECT COUNT(CallID) AS [Total Calls], AssignmentGroup, Assignee FROM #Assignment GROUP BY AssignmentGroup, Assignee ORDER BY COUNT(CallID) DESC , AssignmentGroup, Assignee
What I need to do is write a trigger for on INSERT to automatically update the Assignee column with the name of the person who currently has the least active calls. For example, using the data above, the next PC Support call will go to Mickey Mouse, and the next two Service Desk calls will go to Jim Smith.
So, the logic for the trigger would be
UPDATE #Assignment SET Assignee = (SELECT Assignee FROM #Assignment WHERE COUNT(CallID) = MIN(COUNT(CallID))
But that's only the logic, and obviously it doesn't work with the syntax being nothing like correct.
Does any one have an idea or pointers as to how I should go about this?
I have installed SQL Server Express Edition. I have migrated a set of tables from Oracl10g (by using Microsoft's Migration Tool Kit).While I am trying the following simple update command, the session hangs and it never finishes !!!!!!!!!!!!
Tab_Name & Load_Status columns provides the information about Name of table and status of data getting loaded to this table.
To this I would like to add a column to display the running count in the table, I mean how many records so far loaded, as below the recordCount coming from the same table tbl_collection
Hi guys,I have a simple field in a table in my sql server DB. All i need to dois update a count on it, from 5 to 6, from 6 to 7, so on. A simple counter.Do I have to SELECT the count field once, get the value, do the addingin my program, then do another command to update the count field? Ordoes SQL syntax allow a simple increment function?Thanks!Buck
I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.
I am trying to write a stored procedure that updates a value in a table based on the sort order. For example, my table has a field "OfferAmount". When this field is updated, I need to resort the records and update the "CurrRank" field with values 1 through whatever. As per my question marks below, I am not sure how to do this.
Update CurrRank = ??? from tblAppKitOffers where appkitid = 3 AND (OfferStatusCode = 'O' OR OfferStatusCODE = 'D') ORDER BY tblAppKitOffers.OfferAmount Desc

I am trying to update a users status from Pending to either Approved or Rejected. I created the following handers to update me db by I keep getting a syntax error. What am I doing wrong? public partial class admin_beta : System.Web.UI.Page{ protected void ApproveButton_Click(object sender, EventArgs e) { SqlConnection conn = new SqlConnection("Data Source=TECATE;Initial Catalog=subscribe_mainSQL; User Id=maindb Password=$$ricardo; Integrated Security=SSPI"); SqlCommand cmd = new SqlCommand("UPDATE [main] ([status]) VALUES (@status)", conn); conn.Open(); cmd.Parameters.AddWithValue("@status", "Approved"); int i = cmd.ExecuteNonQuery(); conn.Dispose(); } protected void DenyButton_Click(object sender, EventArgs e) { SqlConnection conn = new SqlConnection("Data Source=TECATE;Initial Catalog=subscribe_mainSQL; User Id=maindb Password=$$ricardo; Integrated Security=SSPI"); SqlCommand cmd = new SqlCommand("UPDATE [main] ([status]) VALUES (@status)", conn); conn.Open(); cmd.Parameters.AddWithValue("@status", "Rejected"); int i = cmd.ExecuteNonQuery(); conn.Dispose(); }}
Hi,Its probably simple but.. How do I update a column by just '1'..for example - heres my code: protected void Button1_Click(object sender, EventArgs e) { SqlConnection con = new SqlConnection(); con.ConnectionString = "HiddenConnection"; con.Open(); SqlCommand command = new SqlCommand(); command.Connection = con; Label productIDLabel = (Label)DataList1.FindControl("productIDLabel"); command.CommandText = "UPDATE Items SET numberclickedin = numberclickedin + 1 WHERE productID=@productID"; command.Parameters.Add("@productID", productIDLabel.Text); command.ExecuteNonQuery(); con.Close(); command.Dispose(); } As you can see in the bold text, I want to add 1 to the numberclickedin column.. and in my primative way Ive just typed +1What should I use instead?Thanks in advance,Jon
How can I create an update statement that will allow me to fill in a column if the previous column already has data in it? I am trying to do and UPDATE/SET command that allows me to extract information and populate columns within a table. However, the UPDATE/SET has to make sure that it is not overwriting information that is already in the column and if there is, to populate the column next to it, and so on until all the columns are populated.
In my UPDATE/SET I am pulling data from another table to populate into the 'add_diag' columns however, I'm not sure how to write in SQL the ability to monitor all the columns, and if for example the first three are full to then populate into the fourth and so on.
Here is my UPDATE/SET statement (while involved, I think I need something in my WHERE clause in order for this to be resolved):
Code:
update ad set add_diag_1=dsm_code from #add_diags ad join Doc_Entity de on ad.patient_id=de.patient_id and ad.episode_id=de.episode_id and doc_code = 'DCDIAG' join Patient_Assignment pa on de.patient_assignment_id = pa.patient_assignment_id and convert(char(8),de.effective_date,112) = convert(char(8),pa.date_discharged,112) left outer join Doc_Diag_Axis_I_III dx1 on de.doc_session_no=dx1.doc_session_no and de.current_version_no=dx1.version_no where dx1.sequence_no=2 and de.is_locked = 'Y' and dx1.rule_out = 'N' and is_billable = 'Y' and dx1.axis_type IN ('1','2') and de.status in ('CO' , 'SA')
We have SharePoint list which has, say, two columns. Column A and Column B.
Column A can have three values - red, blue & green.
Column B can have four values - pen, marker, pencil & highlighter.
A typical view of list can be:
Column A - Column B red  - pen red - pencil red - highlighter blue - marker blue - pencil green - pen green - highlighter red  - pen blue - pencil blue - highlighter blue - pencil
We are looking to create a report from SharePoint List using SSRS which has following view:
          red   blue  green   pen       2    0    1   marker    0    1    0   pencil      1    3    0   highlighter  1    1    1Â
We tried Sum but not able to display in single row.
Please excuse my ignorance. I've researched this and it appears I am asking to do something that is ridiculous, so please let me know what is wrong with my design (or my brain). I'd like to update an ID number in a table. It is an identity column. In my solution I'm adding a lot of new entries into my table and deleting old ones. Call me anal, but It's driving me nuts that my ID numbers are growing so large so quickly and that I have so many unused ID's. If you were to look over my data ID's they would be something like 1,3,45,78,88,89,103,140,219. What I'm trying to do is renumber my data so that my data currently at say ID# 1067 can be moved to the unused ID#2, etc. So I either need a way to update an Identity column...or I need a way find the lowest unused number among a list of ID's. So is there anyway to achieve what I am trying to do? I see this guy had my same OCD issue (without a solution) :-(
how can i update a column with datatype of text with a combination of columns having a datatype of float? do i convert the float columns to varchar/char/?? and/or can i convert the column i am updating?
If amc.amc2>0 then “UPDATE amc set AMC2= AMC2 + “ & val(txtamt.text) & “where am1=1” else if amc.amc2<0 then “UPDATE amc set AMC2= “ & val(txtamt.text) & “where am1=1” end if
Here I check the value of column with if condition statement. I need to check the column with out if condition statement.
What is my doubt is that how I can check value of amc2 column while updating.
eg: update amc set case when amc2>0 then AMC2= AMC2 + “ & val(txtamt.text) like this
Is it possible with “case-when -end”?
If it is possible I can solve a big problem in my project. Can you give me an example with this query?
