  • SQL Convert Nvarchar(255) to DateTime problem

    - by steven
    Hi, I'm using SQL server 2008. I have 2 Tables: Table 1 and Table 2. Table 1 has 1 column called: OldDate which is nvarchar(255), null Table 2 has 1 column called: NewDate which is datetime, not null Example data in Table 1: 26/07/03 NULL NULL 23/07/2003 7/26/2003 NULL 28/07/03 When i try CAST(OldDate as datetime) I get this error: Arithmetic overflow error converting expression to data type datetime. I need to insert OldDate into NewDate with no errors. I can't skip some rows. Anyhelp would be appreciated.

  • SQL: Optimize insensive SELECTs on DateTime fields

    - by Fedyashev Nikita
    I have an application for scheduling certain events. And all these events must be reviewed after each scheduled time. So basically we have 3 tables: items(id, name) scheduled_items(id, item_id, execute_at - datetime) - item_id column has an index option. reviewed_items(id, item_id, created_at - datetime) - item_id column has an index option. So core function of the application is "give me any items(which are not yet reviewed) for the actual moment". How can I optimize this solution for speed(because it is very core business feature and not micro optimization)? I suppose that adding index to the datetime fields doesn't make any sense because the cardinality or uniqueness on that fields are very high and index won't give any(?) speed-up. Is it correct? What would you recommend? Should I try no-SQL? -- mysql -V 5.075 I use caching where it makes sence.

  • All of a Sudden , Sql Server Timeout

    - by Adinochestva
    Hey Guys We got a legacy vb.net applicaction that was working for years But all of a sudden it stops working yesterday and gives sql server timeout Most part of application gives time out error , one part for example is below code : command2 = New SqlCommand("select * from Acc order by AccDate,AccNo,AccSeq", SBSConnection2) reader2 = command2.ExecuteReader() If reader2.HasRows() Then While reader2.Read() If IndiAccNo <> reader2("AccNo") Then CAccNo = CAccNo + 1 CAccSeq = 10001 IndiAccNo = reader2("AccNo") Else CAccSeq = CAccSeq + 1 End If command3 = New SqlCommand("update Acc Set AccNo=@NewAccNo,AccSeq=@NewAccSeq where AccNo=@AccNo and AccSeq=@AccSeq", SBSConnection3) command3.Parameters.Add("@AccNo", SqlDbType.Int).Value = reader2("AccNo") command3.Parameters.Add("@AccSeq", SqlDbType.Int).Value = reader2("AccSeq") command3.Parameters.Add("@NewAccNo", SqlDbType.Int).Value = CAccNo command3.Parameters.Add("@NewAccSeq", SqlDbType.Int).Value = CAccSeq command3.ExecuteNonQuery() End While End If It was working and now gives time out in command3.ExecuteNonQuery() Any ideas ?

  • Can't figure out what's wrong with my php/sql statement

    - by Olegious
    So this is probably a dumb beginner question, but I've been looking at it and can't figure it out. A bit of background: just practicing making a web app, a form on page 1 takes in some values from the user, posts them to the next page which contains the code to connect to the DB and populate the relevant tables. I establish the DB connection successfully, here's the code that contains the query: $conn->query("SET NAMES 'utf9'"); $query_str = "INSERT INTO 'qa'.'users' ('id', 'user_name','password' ,'email' ,'dob' ,'sx') VALUES (NULL, $username, $password, $email, $dob, $sx);"; $result = @$conn->query($query_str); Here's the error that is returned:Insert query failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''qa'.'users' ('id', 'user_name' ,'password' ,'email' ,'dob' ,'s' at line 1 Thanks in advance!

  • SQL - logical AND among multiple rows

    - by potrnd
    Hello, First of all sorry that I could not think of a more descriptive title. What I want to do is the following using only SQL: I have some lists of strings, list1, list2 and list3. I have a dataset that contains two interesting columns, A and B. Column A contains a TransactionID and column B contains an ItemID. Naturally, there can be multiple rows that share the same TransactionIDs. I need to catch those transactions that have at least one item ID that exists whithin each list (list1, list2 AND list3). I also need to count how many times does that happen for each transaction. I hope that makes enough sense, perhaps I will be able to explain it better with a clear head. Thanks in advance

  • Working with sets of rows in (My)SQL and comparing values

    - by Pep.
    Hello, I am trying to figure out the SQL for doing some relatively simple operations on sets of records in a table but I am stuck. Consider a table with multiple rows per item, all identified by a common key. For example: serial model color XX1 A blue XX2 A blue XX3 A green XX5 B red XX6 B blue XX1 B blue What I would for example want to do is: Assuming that all model A rows must have the same color, find the rows which dont. (for example, XX3 is green). Assuming that a given serial number can only point to a single type of model, find out the rows which that does not occur (for example XX1 points both to A and B) These are all simple logically things to do. To abstract it, I want to know how to group things by using a single key (or combination of keys) and then compare the values of those records. Should I use a join on the same table? should i use some sort of array or similar? thanks for your help

  • Inserting timestamp value in SQL Server

    - by JPro
    I am trying to copy data from my MYSQL table to SQL Server using PHP. I have a TimeStamp value that needs to be copied. While I am trying to copy the fields, it gave an error that timestamp value cannot be inserted. Is there any way to insert the timestamp value? Is it is not possible, then declaring the column as nvarchar will insert the timestamp, but will I be able to search the data in a date range? Can anyone please clarify my doubt? Thanks.

  • SQL and multiple statements in stored procedure

    - by Sjemmie
    I'm working on SQL server 2005 and I have a very simple stored procedure: create PROCEDURE [dbo].[tblTabel_Insert] @ID int, @Code nvarchar(50) = null AS SET NOCOUNT ON; IF EXISTS (SELECT ID, code FROM tblTabel WHERE ID = @ID and code = @Code) UPDATE tblTabel SET ID = @ID,code = @Code WHERE ID = @ID ELSE BEGIN INSERT INTO tblTabel (ID,code) VALUES ( @ID ,@Code); END My question is: is it posible to have multiple queries in my stored procedure ? I want to add the lines UPDATE tblTabelB SET ID = @ID,code = @Code WHERE ID = @ID UPDATE tblTabelC SET ID = @ID,code = @Code WHERE ID = @ID in my if exists section. How do I change my stored procedure in the correct way ?

  • compare date split across colums

    - by alex-tech
    Greetings. I am querying tables from Microsoft SQL 2008 which have date split across 3 columns: day, month and year. Unfortunately, I do not have control over this because data is coming in to the database daily from a 3rd party source in that format. I need to add between to a where clause so user can pull records within a range. Would be easy enough if date was in a single column but finding it nearly impossible when its split across three columns. To display the date, I am doing a CAST( CAST(year as varchar(4)) + '-' + CAST(month as varchar(2)) + '-' + CAST(day as varchar(2)) as date) AS "date"` in a select. I tried to put it as a parameter for datediff function or just the regular between but get no results. Thanks for any help.

  • Update multiple values in a single statement

    - by Kluge
    I have a master / detail table and want to update some summary values in the master table against the detail table. I know I can update them like this: update MasterTbl set TotalX = (select sum(X) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID) update MasterTbl set TotalY = (select sum(Y) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID) update MasterTbl set TotalZ = (select sum(Z) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID) But, I'd like to do it in a single statement, something like this: update MasterTbl set TotalX = sum(DetailTbl.X), TotalY = sum(DetailTbl.Y), TotalZ = sum(DetailTbl.Z) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID group by MasterID but that doesn't work. I've also tried versions that omit the "group by" clause. I'm not sure whether I'm bumping up against the limits of my particular database (Advantage), or the limits of my SQL. Probably the latter. Can anyone help?

  • File folder sql programming

    - by eski
    I'm trying to figure out the best way to make a file folder system in sql. I'm making a website that will be using similar system as explorer in windows. You open your c: drive and you see there some folders and files, and you open one folder and you see more files and folders there. So what i'm asking, would i use one table for this and just point to the parent id number or what ? I have this in my head.. You make a Primary folder, it gets the u_id=1. Then i make a file in that folder, it gets u_id=2 and p_id=1 so i know its there right? same with the folders. This would all be in one table but i cant help thinking there is some major flaw in this..

  • What to do if 2 (or more) relationship tables would have the same name?

    - by primehunter326
    So I know the convention for naming M-M relationship tables in SQL is to have something like so: For tables User and Data the relationship table would be called UserData User_Data or something similar (from here) What happens then if you need to have multiple relationships between User and Data, representing each in its own table? I have a site I'm working on where I have two primary items and multiple independent M-M relationships between them. I know I could just use a single relationship table and have a field which determines the relationship type, but I'm not sure whether this is a good solution. Assuming I don't go that route, what naming convention should I follow to work around my original problem?

  • Delete data with foreign key in SQL Server table

    I'm going to delete data in an SQL Server table (parent) which has a relationship with another table (child). I tried the basic Delete query. But it isn't working (and I know it won't). DELETE FROM table WHERE ... It returned following error The DELETE statement conflicted with the REFERENCE constraint ... I need to keep the table's schema. I know that I just need to add some words in the query, I've ever done this before, but I just couldn't recall it.

  • Put empty spaces in an SQL select

    - by David Undy
    I'm having difficulty creating a month-count select query in SQL. Basically, I have a list of entries, all of which have a date associated with them. What I want the end result to be, is a list containing 12 rows (one for each month), and each row would contain the month number (1 for January, 2 for February, etc), and a count of how many entries had that month set as it's date. Something like this: Month - Count 1 - 12 2 - 0 3 - 7 4 - 0 5 - 9 6 - 0 I can get an result containing months that have a count of higher than 0, but if the month contains no entries, the row isn't created. I get this result just by doing SELECT Month(goalDate) as monthNumber, count(*) as monthCount FROM goalsList WHERE Year(goalDate) = 2012 GROUP BY Month(goalDate) ORDER BY monthNumber Thanks in advance for the help!

  • Microsoft SQL Server xml data

    - by cf_PhillipSenn
    This site has a technique to pass xml data around in Microsoft SQL Server: DECLARE @productIds xml SET @productIds ='<Products><id>3</id><id>6</id><id>15</id></Products>' SELECT ParamValues.ID.value('.','VARCHAR(20)') FROM @productIds.nodes('/Products/id') as ParamValues(ID) But what is the syntax if I add another field? The following does NOT work: DECLARE @productIds xml SET @productIds ='<Products><id>3</id><descr>Three</descr><id>6</id><descr>six</descr><id>15</id><descr>Fifteen</descr></Products>' SELECT ParamValues.ID.value('.','VARCHAR(20)') ,ParamValues.descr.value('.','VARCHAR(20)') FROM @productIds.nodes('/Products/id') as ParamValues(ID) Note: Maybe I've constructed my xml wrong.

  • Filter rows on the basis of "First Name" + "Last Name" in SQL

    - by Raghav Khunger
    Hi, I have a user table in my database which contains two columns FirstName and LastName. Now in my front end there is a textbox to filter out the users from this table. Let's suppose I am taking that input from the front end in the form of a input parameter "@SEARCHKEYWORD". I have created a sample below: DECLARE @Test TABLE ([ID] INT IDENTITY, [FNAME] NVARCHAR(100), [LNAME] NVARCHAR(100) ) INSERT INTO @Test( FNAME, LNAME ) SELECT 'John','Resig' UNION ALL SELECT 'Dave','Ward' UNION ALL SELECT 'Peter','Smith' UNION ALL SELECT 'Dave','Smith' UNION ALL SELECT 'Girija','Acharya' UNION ALL SELECT 'Devendra', 'Gujel' UNION ALL SELECT 'Arjit', 'Gupta' DECLARE @SEARCHKEYWORD NVARCHAR(100) SELECT * FROM @Test WHERE FNAME +' '+ LNAME LIKE @SEARCHKEYWORD i.e. so far I have thought of this query to filter out the rows but it is not giving the desired results: SELECT * FROM @Test WHERE FNAME +' '+ LNAME LIKE @SEARCHKEYWORD Here are the desired outputs which I needed for the inputs mentioned below: --WHEN @SEARCHKEYWORD='John Resig' --Desired OUTPUT: the row which contains 'John','Resig' --WHEN @SEARCHKEYWORD='Ac' --Desired OUTPUT: the row which contains 'Girija','Acharya' --WHEN @SEARCHKEYWORD='Smith' --Desired OUTPUT: the row which contains 'Peter','Smith' and 'Dave','Smith' --WHEN @SEARCHKEYWORD='g' --Desired OUTPUT: the row which contains 'Devendra', 'Gujel' and 'Arjit', 'Gupta' --WHEN @SEARCHKEYWORD='Smith' --Desired OUTPUT: the row which contains 'Peter','Smith' and 'Dave','Smith'

  • SQL Server insert with XML parameter - empty string not converting to null for numeric

    - by Mayo
    I have a stored procedure that takes an XML parameter and inserts the "Entity" nodes as records into a table. This works fine unless one of the numeric fields has a value of empty string in the XML. Then it throws an "error converting data type nvarchar to numeric" error. Is there a way for me to tell SQL to convert empty string to null for those numeric fields in the code below? -- @importData XML <- stored procedure param DECLARE @l_index INT EXECUTE sp_xml_preparedocument @l_index OUTPUT, @importData INSERT INTO dbo.myTable ( [field1] ,[field2] ,[field3] ) SELECT [field1] ,[field2] ,[field3] FROM OPENXML(@l_index, 'Entities/Entity', 1) WITH ( field1 int 'field1' ,field2 varchar(40) 'field2' ,field3 decimal(15, 2) 'field3' ) EXECUTE sp_xml_removedocument @l_index EDIT: And if it helps, sample XML. Error is thrown unless I comment out field3 in the code above or provide a value in field3 below. <?xml version="1.0" encoding="utf-16"?> <Entities> <Entity> <field1>2435</field1> <field2>843257-3242</field2> <field3 /> </Entity> </Entities>

  • SQL Server: Output an XML field as tabular data using a stored procedure

    - by Pawan
    I am using a table with an XML data field to store the audit trails of all other tables in the database. That means the same XML field has various XML information. For example my table has two records with XML data like this: 1st record: <client> <name>xyz</name> <ssn>432-54-4231</ssn> </client> 2nd record: <emp> <name>abc</name> <sal>5000</sal> </emp> These are the two sample formats and just two records. The table actually has many more XML formats in the same field and many records in each format. Now my problem is that upon query I need these XML formats to be converted into tabular result sets. What are the options for me? It would be a regular task to query this table and generate reports from it. I want to create a stored procedure to which I can pass that I need to query "<emp>" or "<client>", then my stored procedure should return tabular data.

  • SQL Outer Join on a bunch of Inner Joined results

    - by Matthew Frederick
    I received some great help on joining a table to itself and am trying to take it to the next level. The SQL below is from the help but with my addition of the select line beginning with COUNT, the inner join to the Recipient table, and the Group By. SELECT Event.EventID AS EventID, Event.EventDate AS EventDateUTC, Participant2.ParticipantID AS AwayID, Participant1.ParticipantID AS HostID, COUNT(Recipient.ChallengeID) AS AllChallenges FROM Event INNER JOIN Matchup Matchup1 ON (Event.EventID = Matchup1.EventID) INNER JOIN Matchup Matchup2 ON (Event.EventID = Matchup2.EventID) INNER JOIN Participant Participant1 ON (Matchup1.Host = 1 AND Matchup1.ParticipantID = Participant1.ParticipantID) INNER JOIN Participant Participant2 ON (Matchup2.Host != 1 AND Matchup2.ParticipantID = Participant2.ParticipantID) INNER JOIN Recipient ON (Event.EventID = Recipient.EventID) WHERE Event.CategoryID = 1 AND Event.Resolved = 0 AND Event.Type = 1 GROUP BY Recipient.ChallengeID ORDER BY EventDateUTC ASC My goal is to get a count of how many rows in the Recipient table match the EventID in Event. This code works fine except that I also want to get results where there are 0 matching rows in Recipient. I want 15 rows (= the number of events) but I get 2 rows, one with a count of 1 and one with a count of 2 (which is appropriate for an inner join as there are 3 rows in the sample Recipient table, one for one EventID and two for another EventID). I thought that either a LEFT join or an OUTER join was what I was looking for, but I know that I'm not quite getting how the tables are actually joined. A LEFT join there gives me one more row with 0, which happens to be EventID 1 (first thing in the table), but that's all. Errors advise me that I can't just change that INNER join to an OUTER. I tried some parenthesizing and some subselects and such but can't seem to make it work.

  • Linear regression confidence intervals in SQL

    - by Matt Howells
    I'm using some fairly straight-forward SQL code to calculate the coefficients of regression (intercept and slope) of some (x,y) data points, using least-squares. This gives me a nice best-fit line through the data. However we would like to be able to see the 95% and 5% confidence intervals for the line of best-fit (the curves below). What these mean is that the true line has 95% probability of being below the upper curve and 95% probability of being above the lower curve. How can I calculate these curves? I have already read wikipedia etc. and done some googling but I haven't found understandable mathematical equations to be able to calculate this. Edit: here is the essence of what I have right now. --sample data create table #lr (x real not null, y real not null) insert into #lr values (0,1) insert into #lr values (4,9) insert into #lr values (2,5) insert into #lr values (3,7) declare @slope real declare @intercept real --calculate slope and intercept select @slope = ((count(*) * sum(x*y)) - (sum(x)*sum(y)))/ ((count(*) * sum(Power(x,2)))-Power(Sum(x),2)), @intercept = avg(y) - ((count(*) * sum(x*y)) - (sum(x)*sum(y)))/ ((count(*) * sum(Power(x,2)))-Power(Sum(x),2)) * avg(x) from #lr Thank you in advance.
