Can someone write for me an example query that would select all the constraints that are applied to specific table?
something like:
SELECT FieldThatHasConstraint, FieldTableName, TableToWhitchThisFieldHasConstraint, FieldOfTableToWhitchThisFieldHasConstraint TypeOfConstraint FROM ??? WHERE TableThatIWantToSearchForConstraints='myTable'
Is Microsoft full of #*$#*% (again) or am I badly misunderstandingsomething?Quote from Microsoft's T-SQL doc:[color=blue]> INSTEAD OF triggers are executed instead of the triggering action.> These triggers are executed after the inserted and deleted tables> reflecting the changes to the base table are created, but before any> other actions are taken.

Hi, I want know how can I to build a query to get all the foreignkey contrains exist between tables using the sys tables, for example if the user select this two tables:
dbo.cat_states -> with this fields -> id_state & desc dbo.cat_universities -> with this fields -> id_state, id_university & desc_university
Hi all, I have a big problem. I have many tables with constraints, with foreign keys. I need to create a ordered list of tables, on the top must be the basic table what has no parents, then the second level tables (those depends on the first level) the the names of third level etc.
I am having trouble loading tables (within the same data flow) that have a foriegn key relationship defined between them. For instance:
Table A is a parent (one side of the relationship) to Table B (many side of the relationship).
I am trying to load Table A first within the data flow and then Table B after, but I get the following error:
[OCMD EntityRole Insert [2666]] Error: An OLE DB error has occurred. Error code: 0x80040E2F. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E2F Description: "The statement has been terminated.". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E2F Description: "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_EntityRole_Entity". The conflict occurred in database "ODS", table "dbo.Entity", column 'EntityGuid'.".
I am currently using OLE DB commands to perform the inserts, I load table A and move on to then load Table B, I can see the records in Table A before trying to load Table B but for some reason Table B load still fails.
I was thinking maybe this has something to do with the transaction setting or Isolation level but have played with this to no avail (currently everything is the default - supported/serializable). Also, I am thinking maybe because the OLE DB commands are creating two seperate connections (they are using the same connection manager) the second one is unable to see the transactions from the other (first) connection (Table A)?
Is there a way around this without dropping (disabling) forigen keys before the load and adding them back in after? Would like to avoid this?
I would also like to avoid reading the data source multiple times. Everything I need is in the one source so I would like to populate multiple tables from the one source data stream instead of reading the same data 2,3 or 4 times etc.
Seems to me there must be a simple explanation/solution for this but I'm stuck at this point?
P.S.
I was intially using OLE DB destinations (because they are much faster) and was having the same issue, which made sense because the OLE DB destinations do not let you pass the data stream on so I had to multi cast to the destinations so they were loading at the same time. I would rather use the OLE DB destinations so if you have any ideas around how I could do this using those components that would be appreciated too!
I have a slight problem which I'm sure must be a common happening. Here's my problem.
I'm using Merge replication and I have a table the has a unique contraint on a non primary key column (the column is called [name]). The thing that goes wrong (for me) is that when a new record is added in a subscriber and a new record is added in the publisher before a synchronization and both records have the same [name] value then when the merge agent runs I get an unresolved conflict because of a unique index violation.
I've read the BOL and I'm left thinking that in order to solve this problem then I must use a custom resolver. Is this the best way of handling such a conflict? Actually if it is I'm still a little stuck as I'm not sure what I could do to help the situation inside the custom resolver anyway!!
I was wondering if there is an easy way to loop through all contraints in a database and programmatically set the cascade delete to ON. I have a database with hundreds of contraints, so individually setting cascade delete on them is not optimal.
Thanks for any info in advance!
I think that the constraints are simply held in one of the system datatables, is there anyway to simply update that table?
Is there any easy way to truncate a table which has a foreign key restraint? I want to override the default behavior which is to not allow truncate of parent tables. I want to be able to temperarily remove the contraint so I can truncate the temple, how do you do this?
First of all, this is my initial thread here on dbforums. I come from the land of Broadband Reports and would like to say, Hello fellow DB enthusiasts. :)
I'm not a novice to relational databases (Access MDBs), but new to implementing a db via SQL SERVER (2000 in this case) and using Access Data Projects.
Sample Data would be 1 | CRYS | CRYSTAL STAIRS 2 | MAOF | MEXICAN AMERICAN FOUNDATION 3 | PATH | PATHWAYS 4 | CCRC | CHILD CARE RESOURCE CENTER 5 | CHSC | CHILDREN'S HOME SOCIETY OF CALIFORNIA ==========================================
THE REMAINING "FKs" FROM SCHOOL ARE SIMILAR, as is other tables and their relationships. The design of the foreign keys were made using sql and the keyword "REFERENCES" and "FOREIGN KEY."
My questions are: :confused: (1) Is the use of FK as a Constraint any different than using an INDEX and how? (2) Should I Alter the Tables to include CASCADING Up/Down? (3) Are the use of CHARs Ok for the Keys? (4) Have I over/under-normalized any of the relationships?
HiI am using SQL 2005, VB 2005I am trying to insert a record using parameters using the following code as per MotLey suggestion and it works finestring insertSQL; insertSQL = "INSERT INTO Issue(ProjectID, TypeofEntryID, PriorityID ,Title, Area) VALUES (@ProjectID, @TypeofEntryID, @PriorityID ,@Title, @Area)"; cmdInsert SqlCommand; cmdInsert=new SqlCommand(insertSQL,conn); cmdInsert.Parameters.Add("@ProjectID",SqlDbType.Varchar).Value=ProjectID.Text; My query is how to detail with dates my previous code wasinsertSQL += "convert(datetime,'" + DateTime.Now.ToString("dd/MM/yy") + "',3), '";I tried the code below but the record doesn't save?string date = DateTime.Now.ToString("dd/MM/yy"); insertSQL = "INSERT INTO WorkFlow(IssueID, TaskID, TaskDone, Date ,StaffID) VALUES (@IDIssue, @IDTask, @TaskDone, convert(DateTime,@Date,3),@IDStaff)"; cmdInsert.Parameters.Add("IDIssue", SqlDbType.Int).Value = IDIssue.ToString();cmdInsert.Parameters.Add("IDTask",SqlDbType.Int).Value = IDTask.Text;cmdInsert.Parameters.Add("TaskDone",SqlDbType.VarChar).Value = TaskDoneTxtbox.Text;cmdInsert.Parameters.Add("Date",SqlDbType.DateTime).Value = date;cmdInsert.Parameters.Add("IDStaff",SqlDbType.Int).Value = IDStaff.Text;Could someone point to me in the right direction?Thanks in advance
My goal is to select values from the same date range for a month on month view to compare values month over month. I've tried using the date trunc function but I'm not sure what the best way to attack this is. My thoughts are I need to somehow select first day of every month + interval 'x days' (but I don't know the syntax).In other words, I want to see
Select Jan 1- 23rd feb 1-23rd march 1-23rd april 1-23rd ,value from table
For this id: 0793319, my beginning date is 2011-09-06

108203492014-09-022015-06-30
For this id: 0820349, my beginning date is 2014-09-02
To find continuous date, you look at the beginning date in row 1 and end date in row 2, then if no break in dates, row 2 beginning date to row 3 end date, if no break continue until last date There could multiple dates up to 12 which I have to check for "no break" in dates, if break, display beginning date of last continuous date.
I want to compare two columns in the same table called start date and end date for one clientId.if clientId is having continuous refenceid and sartdate and enddate of reference that I don't need any caseopendate but if clientID has new reference id and it's start date is not continuous to its previous reference id then I need to set that start date as caseopendate.
Hi,I have a problem with updating a datetime column,When I try to change the Column from VB I get "Incorrect syntax near'942'" returned from [Microsoft][ODBC SQL Server Driver][SQL Server]'942' is the unique key column valueHowever if I update any other column the syntax is fineThe same blanket update query makes the changes no matter what isupdatedThe problem only happens when I set a unique key on the date field inquestionKey is a composite of an ID, and 2 date fieldsIf I allow duplicates in the index it all works perfectlyI am trying to trap 'Duplicate value in index' (which is working onother non-date columns in other tables)This is driving me nutsAny help would be appreciated
So I have to build dynamic T-SQL because of a date parameter that will be provided. The Date Parameter will be provided in SSRS in normal MM/DD/CCYY format. So how do I then convert that date to my Oracle format
Hi, Basically the above is a very common requirement, please comment on my solution which I've arrived at by searching through the web; -
In summary I have used 3 SSIS components these are "Flat File Source", "Derived Column" and "SQL Server Destination".
1) File Connections Manager Editor 1.1) Within File Connections Manager Editor; - Name the data type e.g. "INTERCHANGE_NET_APP_DATE_SRC" and assign a type to the data type e.g. string[DT_STR]
1.2) Click on the Preview button to ensure the expected text is assigned to the expected data type.
2.4) Select "database timestamp [DT_DBTIMESTAMP] " as Data Type.
2.5) Within the Mappings tab of the SQL Destination Editor have; - Input Column as INTERCHANGE_NET_APP_DATE and Destination Column as INTERCHANGE_NET_APP_DATE.
Please comment on the above, I will then pass on my suggestion to Microsoft.
Hi there. I'm trying to extract data from my SQL server & everything in the script I've got is working (extracting correct data) except for one field - which is for the most part it's off by +2 days (on a few occasions - I see it off by just +1 day or even +3, but it's usually the +2 days).
I'm told that it's due to the conversion formula - but - since SQL is not my native language, I'm at a bit of a loss.
The DB table has the date field stored as a type: CHAR (as opposed to 'DATE') Can anyone out there help?

The insert column I am trying to get into is a date type. The original state of the field is YYYYMM varchar. How to get this into the table.
I asked this question below, but the answer was that the conversion will take place automatically, but I can't get that to happen. I have a flat file with an 8 position field that I identify as string (and I also tried date) that is yyyymmdd and it needs to go into the database field that is datetime format. IS there something I am doing wrong with the definition of it, or do I need to add some kind of conversion, and if so, what and how would that be done. I'm a dts Sql2000 expert, but the SSIS thing is driving me crazy. I have a ton of dts' to convert and the migration tool doesn't work because there are a lot of active X scripts in them. thanks for your help. Boston Rose
A server with SQL 2005 sp2, Reporting Services and Sharepoint services (ver 3.0) (in integrated mode) gives an odd error. When viewing a Reporting Services report with a Date Time Picker, the date chosen is wrong. The preferred setting is Danish with the date format dd-mm-yyyy. The date picker shows the months in Danish but when selecting a date, and clicking on the Apply-button, the date reformats to US (mm-dd-yyyy).
Example: When choosing 5th of September 2007 and clicking apply, it shows in the picker, 9th of May 2007. When choosing 26th of September 2007 and clicking apply, it shows, again in US format, the RIGHT date but adds a timestamp 12:00 AM? in the end, making further enquiries to fail.
The report itself receives the right date and shows correctly. The only case it fails is, when the time stamp appears.
The server is a 32-bit one with 4 GB RAM. A testserver with identical collation on the Reportserver database cannot recreate the error. The site containing the reports has been set to Danish in the regional settings. To Reinstall is not an option.
The test report has no database connection whatsoever.
When setting the site to US, the timestamp wont appear at all.
The server has been restarted and the installation procedure was of the simple kind. No special tweaks at all.
I have a table here. I want find a way of getting the latest date, when the code is the same. If the Declined date is null. Then I still want the latest date. E.g. ID 3.
If the declined date is filled in. Then I want to get the row, when the Datein column value is greater then the declined date only.
I tried grouping it by max date, but i got an error message when trying this out. Against the code
WHERE MAX(Datein) > Declined
An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference. What do I need to do to get both my outputs working?
i have written a sql function which returns only number of working days (excludes holidays and Weekends) between given StartDate and EndDate.
USE [XXX] GO /****** Object: UserDefinedFunction [dbo].[CalculateNumberOFWorkDays] Script Date: 10/28/2015 10:20:25 AM ******/ SET ANSI_NULLS ON GO
[code]...
I need a function or stored procedure which will return the date which is 15 working days (should exclude holidays and Weekends) prior to the given future Date? the future date should be passed as a parameter to this function or stored procedure to return the date. Example scenario: If i give date as 12/01/2015, my function or stored procedure should return the date which is 15 working days (should exclude holidays and Weekends) prior to the given date i.e 12/01/2015...In my application i have a table tblMasHolidayList where all the 2015 year holidays dates and info are stored.
I am having report parameter end date I am showing the default value "5/21/2007 11:59:59 PM" in the end date paramter. And also I want to show date time format "(MM/DD/YYYY HH:MMS)" in the right hand side of the parameter. How to do this?
So my data column [EODPosting].[MatchDate] is defined as a DATE column. I am trying to SELECT from my table where [EODPosting].[MatchDate] is today's date.
Is this not working because GETDATE() is like a timestamp format? How can I get this to work to return those rows where [EODPosting].[MatchDate] is equal to today's date?
