Populating Data From One SQL Database To Another
Jul 13, 2007I have a project that entails the following:
There are two separate SQL Server databases involved that reside on two different servers. One of the depts within our building wants to have building permit data imported from Permit Database on Server "A" to their own database on Server "B".
I dont think this will be an overly complicated process. There are only a few fields they want populated (5 or 6 tops). This will have to be ran every
weeknight via some sort of scheduled task in Windows or SQL.
I was just interested in seeing if anyone has had prior experience working on data transfer like this. I would like to know what would be the best and most efficient way to approach this.
Thanks in advance.

Populating A Database With Data From Db If A Value Exists
Nov 16, 2004Hi all,
I have a table where I want to populate it with data (certain fields) from another table. But I only want to populate the table if there is data in a certain field in the table I wish to get the data from.
How exactly would I do this test? Would an I have to perform an IF statement to test if the field contains a value first?
Thanks

T-SQL (SS2K8) :: Populating Data For Every Day Of The Week?
May 21, 2015I have a date table(A) for every day of the year from 1990-2016 including the week number.There is another table(B) that has a number, date and week number.
I would like to join these 2 tables together, in order to populate the number from table B on every day of the week (of the week number in table B).
What makes it a little more complex is that the dates in table B not always correspond with the week number in the same row. Adding to the problem are some conditions:
- Every day of the week should have a number, and it should never be 0.
- If the 1st date of all rows in table B with the corresponding week number is not the monday of the week (but for example wednesday) it should start with this number on monday.
- Thousands of rows are in table B and for some of them the date corresponds with the week and for some of them they don't
- The rows can be grouped together using the week number.
Take the following example of table B:
B:
ID Date Number WeekNo
1 21-5-2015 25 21
2 23-5-2015 30 21
In this example the dates correspond with the weeknumber, because the 21st and the 23rd of may are week 21. By joining this with the date table (A), by using for example cross apply, I would hope to get the following result;
Date Number WeekNo
18-5 25 21
19-5 25 21
20-5 25 21
21-5 25 21
22-5 25 21
23-5 30 21
24-5 30 21
The same should work if the same example had the week number 22 in every row.
Take the following example of table B:
B:
ID Date Number WeekNo
1 21-5-2015 25 22
2 23-5-2015 30 22
In this example the dates do not correspond with the weeknumber, because the 21st and the 23rd of may are week 21 and not 22. By joining this with the date table (A), I would hope to get the following result;
Date Number WeekNo
25-5 30 22
26-5 30 22
27-5 30 22
28-5 30 22
29-5 30 22
30-5 30 22
31-5 30 22
Because the last result (ordered by date) of the week number 22 is 30, the whole week shows 30 on every day.
Populating DataGridView With Data From Two Tables?
Oct 11, 2007I am sorry for asking such a broad question, but I have been working on this and from what I can gather it can be done. My problem is that much of it has gone right over my head and I am getting more confused the more I read... I'm really, really confused...
Basically, I have a dataGridView that is populated with a number of fields from Table1 (ID, NameID, Status, Phone, Notes). This works fine, BUT I would like to access Table2 and have, where ID in Table2 = NameID in Table1, it load the First Name & Last Name into the dataGridView. I am able to load the information from Table 2 like so: SELECT NameFirst + ' ' + NameLast from Table2", but I can't get both Tables to work correctly.
I would like the dataGridView to be layed out like this:
ID NameID Name (NameFirst + NameLast) Status Phone Notes
I can't for the life of me understand or get this to work (Or for that matter even understand what I am trying to do...
Also, I am using Access 2007.
I would greatly appreciate some help, and possibly some explanation in laymans terms so that I might be able to understand this. I have read a lot about this, but for whatever reason it is just soooooo over my head that I can't follow it whatsoever.
Here is the code as it stands now:
//Populate the DataGridView
string conString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Environment.CurrentDirectory + @"DB.accdb;Jet OLEDBatabase Password=MyPassword;";
// create and open the connection
OleDbConnection conn = new OleDbConnection(conString);
OleDbCommand command = new OleDbCommand();
command = conn.CreateCommand();
// create the DataSet
DataSet ds = new DataSet();
// run the query
command.CommandText = "SELECT ID AS [#], NameID AS [Name], Status AS [Status], Phone AS [Phone], Notes AS [Notes] FROM Table1 WHERE ID = " + textBox13.Text + ";";
OleDbDataAdapter adapter = new OleDbDataAdapter();
adapter = new OleDbDataAdapter(command);
adapter.Fill(ds);
// close the connection
conn.Close();
bindingSource1.DataSource = ds.Tables[0];
dataGridView1.DataSource = bindingSource1;
// set the size of the dataGridView Columns
this.dataGridView1.Columns[0].Width = 10;
this.dataGridView1.Columns[1].Width = 100;
this.dataGridView1.Columns[2].Width = 100;
this.dataGridView1.Columns[3].Width = 100;
this.dataGridView1.Columns[4].Width = 176;
Any help and information is greatly appreciated.
Thanks Again,
Parsing A Field Data And Populating Other Fields
Nov 3, 1999I have just started to look at SQL and have a theory question that I could apply to a test I want to run. I have some legacy data from a previous project and the database was not designed properly (in my opinion). They have ONE field to capture City and State information. All the data is formatted City, State .
Does SQL have commands that can look at data in a field, strip out info before and info after a comma and then write that to other fields?
So, I would like to normalize this to take the data in a field called CityState and parse it, trim it and then populate two new fields 1) City and 2) State.
Thanks for your help!

Finding Date Ranges That Are Covered By Assignments In Data Set
Jan 14, 2014I have a table of employee assignments that I'm narrowing down to a specific group. Employees have multiple assignments (job positions essentially) and each has start and end dates. I need to identify the date range(s) that are covered by the assignments in my data set. Here's an example of data for one person ID. NULL in the end_date just means it is an active assignment. The pos_id column isn't necessary, but it define the data I'm looking at. The end result won't use it.
IDCOMPANYPOS_IDSTART_DATEEND_DATE
999119/2/20119/9/2012
999119/10/20129/10/2012
999119/11/20129/11/2012
999119/12/20126/2/2013
999116/3/20136/30/2013
[Code] ....
In this case I want results to say that ID 999 has a range from 9/2/2011 to NULL. There are no gaps in the date range. Or to say it differently, there's always an assignment starting the next day after an end_date. Or an assignment that overlaps the end and beginning of another assignment.
Here's another example where there is a gap in the ranges.
IDCOMPANYPOS_IDSTART_DATEEND_DATE
333112011-09-022012-08-31
333112012-09-012012-09-10
333112012-09-112012-09-11
333112012-09-122013-01-06
333112013-09-01NULL
There would be 2 result rows for this with a range from 2011-09-02 to 2013-01-06 and a second for 2013-09-01 to NULL.
The end result would be to have a row per date range for every ID. I've written a script that will find the ranges but it is a painful RBAR solution that takes forever to run. Every different path I've gone down trying to solve it ends in evaluating row by row grouped by the Person ID. The assignments are not always continuous, so I can't use a MAX and MIN and there may be 1 or more gaps in the dates to account for.

Jul 19, 2007Hi,
I have tables like the one below for my Stage and dimension tables:
Stage Table
accountid

Dimension Table
accountkey ---- surrogate key (DW key)
accountid ---- business key (transaction's primary key)
name
address
I used slowly changing dimension to detect the changes for the records inside my Dimension table. But I had a problem when a new record exists in the stage table. The accountkey is set as the primary key and it gets its value from a different table which stores the last account key that was created. I cannot load all the changes unless i have a business key. Is there a way that i can get the "last key" from a different table in the data flow area and then supply it together with the other fields in the new output branch of the slowly changing dimension?

Jul 20, 2005I have a combo box where users select the customer name and can eithergo to the customer's info or open a list of the customer's orders.The RowSource for the combo box was a simple pass-through query:SELECT DISTINCT [Customer ID], [Company Name], [contact name],City,Region FROM Customers ORDER BY Customers.[Company Name];This was working fine until a couple of weeks ago.

Grouping In Ranges
Jul 1, 2004Table:
SomeFKID <pk>
StartDateTime <pk>
EndDateTime
SomeValue
Example Scenario:
Data is stored hourly. So there would be 24 records for today for each SomeFKID. I need to be able to pass a TimeSpan (in minutes), a StartDateTime, and an EndDateTime to a stored procedure and return totals in the date range grouped by the TimeSpan. So if I want all records today grouped by 2 hour intervals I would need to pass:
7/1/2004 00:00:00, 7/1/2004 23:59:59, 120 --> and return 12 records one for hours 0-2, one for hours 2-4, etc.
Any advice would be greatly appreciated!

Ranges With Modifiers
Oct 27, 2014I'm trying to write a statement that will return all records within a range. The only problem is that the records can have modifiers on them.For example, a sample range I would want would be all records between 1008 and 1120. I can't use a between statement though because these records can end in modifiers, like 1009X or 1117B. How can I search for records within a range when they have modifiers such as above?

Building a small app for a school nurse......
Have a SP that takes 2 parameters (@login, @logout) both in the form of "convert(varchar,@Login,108)" or 08:00 AM, etc
What I need to do is then check to see:
1. What period did they login in?
2. What period did they logout in?
3. How much time in a period did they actually miss?
The ranges look like:
Set @Period1Start='08:20 AM'
Set @Period1End='09:10 AM'
Set @Period2Start='09:15 AM'
Set @Period2End='10:00 AM'
...
...
...
So.....
if @login = 08:30 AM and @logout = 08:45 then they missed 15 minutes of period 1
If @login = 08:30 AM and @logout = 09:45 then they missed 40 minutes of period 1 AND 30 minutes of period 2
Not knowing all of the time functions in SQl, I am looking for some ideas on how to accomplish this.
Thanks!

How To Pull From Two Date Ranges

I need a query that will pull clients that made payments last year but not this year.
I need the query to use date parameters so I can select any date range for the past year and the current year.
I have listed the tables and fields that might be needed: I'm hoping to do this without temp tables.
Date range is based on the tblPaymentReceipts.PaymentDate
tblClients, ClientID

tblPaymentReceipts, PmtRcptID, PmtID,CleintID,PaymentDate,PaymentAmount

Comparing Date Ranges
Mar 18, 2004I have two sets of dates to work with. One is an existing booking with a start and an end date. The other is a new booking with a start and an end date. I want to compare them and calculate how much overlap there is. If the overlap is over a certain amount (say 4 days), then I want to flag the user.
Is there any thing I can use in terms of a SQL query to assist in this comparison? I'm relatively new to SQL so I'm not entirely sure what functions and keywords are available to me to make this comparison.
Overlapping Integer Ranges ??
Jul 26, 2004:confused: Dont know if this will be tough for the rest of you but for someone who is fairly new to SQL...I cannot figure it out...
I have a table:
Rownumber starttime endtime
1 l 30 l 240
2 l 40 l 120
3 l 50 l 260
4 l 1300 l 1400
Rows 1, 2, and 3 over lap with one another and I am trying to obtain the starttime and endtime values which can cover them all.
I would like to find the overlapping (starttime - endtime) ranges and accept the lowest starttime value and the highest endtime value.
Row 1: 30--------------------240
Row 2: 40--------------120
Row 3: 50----------------------260
Row 4: ...1300---------1440
I would like to include starttime-endtime ranges that do not overlap with any other integer range.
which in this case would be:
Rownumber starttime endtime
1 l 30 l 260
2 l 1330 l 1400
I was thinking of using a cursor and comparing each row to all of the other rows in the table and then setting a boolean in that row if it overlaps with another row in the table...is there a better way of doing this?
Thank you for the help!

2 2004-12-12 420 1020
3 2004-12-14 200 600
4 2004-12-15 0 200
4 2004-12-15 500 1000
I need to be able to return the minutes that are open for each room. The @reservations table shows me the times that are blocked.
I'd like to analyze each row and return an integer range representing gaps in the day, where 0-1440 represents an entire day.
Based on the @reservations table above, I'd like to write something that returns:
room date starttime endtime
2 2004-12-12 0 420
2 2004-12-12 1020 1440
3 2004-12-14 0 200
3 2004-12-14 600 1440
4 2004-12-15 200 500
4 2004-12-15 1000 1440
This result represents the times in minutes that are available.
I have no clue how to do this without using a numbers table and checking each minute in each day for each row in the table. Id like to not do that because of sheer performance reasons. There is a possiblity that I will have hundreds of rows in the @reservations table.
I was hoping someone could provide some insight as to how to approach this. Thank you ahead of time! :)
