• Help with Custom Workflow that checks db

  - by zSysop

  I need to write a workflow that monitors the status of a sql server column/field and does work to some other tables once the column has changed to "Close". (It could wait for days or hours) My application is written in c# .net 3.5. I've done some really simple "hello world" type of apps with windows workflow foundation 3.5 but have not yet grasped how to do go about implementing something like this. Any help with code or articles on this would be extremely useful. Thanks in advance.

• Simplest one-to-many Map case in Hibernate doesn't work in MySQL

  - by Malvolio

  I think this is pretty much the simplest case for mapping a Map (that is, an associative array) of entities. @Entity @AccessType("field") class Member { @Id protected long id; @OneToMany(cascade = CascadeType.ALL, fetch=FetchType.LAZY) @MapKey(name = "name") private Map<String, Preferences> preferences = new HashMap<String, Preferences>(); } @Entity @AccessType("field") class Preferences { @ManyToOne Member member; @Column String name; @Column String value; } This looks like it should work, and it does, in HSQL. In MySQL, there are two problems: First, it insists that there be a table called Members_Preferences, as if this were a many-to-many relationship. Second, it just doesn't work: since it never populates Members_Preferences, it never retrieves the Preferences. [My theory is, since I only use HSQL in memory-mode, it automatically creates Members_Preferences and never really has to retrieve the preferences map. In any case, either Hibernate has a huge bug in it or I'm doing something wrong.]

• What causes this error..please run "exec sp_register_custom_scripting 'CUSTOM_SCRIPT', your_script???

  - by larryr

  Configuration SQL 2005 (Server A) replicates to SQL 2008(Server B) which replicates to SQL 2008(Server C). I recently added a column (to Server A) to a replicated table via script & the DDL change replicated to Server B with out a problem.

• SQL Server 2008 EF 4 - limiting database records returned using permissions?

  - by Chuck

  In our database all tables are linked back to a single table. This table has a bit column to limit whether the record is displayed. Currently the records are filtered on the code side of the website. Is there any way to set up permission so that userA would never see any record in the database where that common bit column was set to true? We are using SQL Server 2008. Alternatively we are also using entity framework 4.0 in .net 4 (in c#) if you have any ideas how it might be accomplished there? Thanks for your feedback.

• how so select similarities in MySQL?

  - by mysqllearner

  Currently, I am doing a search function. Lets say in my database, I have this data: Keyword1 Keyword2 Keyword3 Keysomething Key and the user entered: "Key" as the keyword to search. This is my current query: Q1: SELECT * FROM data WHERE (data_string LIKE '$key%' OR data_string LIKE '%$key%' OR data_string LIKE '%$key') Basically, I have 2 questions: How do I sort by (order by) similarity. From above example, I should have "Key" as my first result. My current result is: Keyword1, Keyword2, Keyword3, Keysomething and Key My SQL query only search by the "data_string" column, what if I want to seach others column? Do I need to do something like this: Q2: SELECT * FROM data WHERE (data_string LIKE '$key%' OR data_string LIKE '%$key%' OR data_string LIKE '%$key') OR (data_other LIKE '$key%' OR data_other LIKE '%$key%' OR data_other LIKE '%$key') ... Is there any better/faster query than Q2?

• show only those columns which have data value

  - by Zankar

  I don't known that it is possible or not but i want to ask a question to you as suppose i have a table as table1 id | mon | tue | wed | thu | fri | sat | sun 1 | 100 | 200 | 0 | 0 | 0 | 0 | 0 2 | 200 | 0 | 300 | 0 | 0 | 0 | 0 So from given table result should be ... id | mon | tue | wed | 1 | 100 | 200 | 0 | 2 | 200 | 0 | 300 | as shown in table1 different columns of week. If all values in a column is 0 or null then query should ignore to show that column(as shown in result) Note: if we run a query as select * from table1 it shows all columns. While I don't wants a query like select id,mon,tue,wed from table1 because no. of showing columns may change. Please reply to me. Thank you....

• Code Golf: Ghost Leg

  - by Anax

  The challenge The shortest code by character count that will output the numeric solution, given a number and a valid string pattern, using the Ghost Leg method. Examples Input: 3, "| | | | | | | | |-| |=| | | | | |-| | |-| |=| | | |-| |-| | |-|" Output: 2 Input: 2, "| | |=| | |-| |-| | | |-| | |" Output: 1 Clarifications Do not bother with input. Consider the values as given somewhere else. Both input values are valid: the column number corresponds to an existing column and the pattern only contains the symbols |, -, = (and [space], [LF]). Also, two adjacent columns cannot both contain dashes (in the same line). The dimensions of the pattern are unknown (min 1x1). Clarifications #2 There are two invalid patterns: |-|-| and |=|=| which create ambiguity. The given input string will never contain those. The input variables are the same for all; a numeric value and a string representing the pattern. Entrants must produce a function. Test case Given pattern: "|-| |=|-|=|LF| |-| | |-|LF|=| |-| | |LF| | |-|=|-|" |-| |=|-|=| | |-| | |-| |=| |-| | | | | |-|=|-| Given value : Expected result 1 : 6 2 : 1 3 : 3 4 : 6 5 : 5 6 : 2

• scrolling a readonly cell in NSTableview?

  - by John Velman

  I have a table that the user should not be able to edit directly (although user actions may cause changes). One column may contain a string too long for any reasonable size cell, so to see everything there, the user needs to scroll the cell (using arrow keys, for example). If I make either the column or cell not editible, I loose the ability to scroll the cell. If I make it editable, of course, I loose the ability to keep the user from changeing it. (I'm using NSArray controller and a couple of NSObject controllers to get from the model to the table view using bindings. Binding compliance via @property(copy) and @synthesize. Updating the model with setXXXX:xxx). Thanks, John Velman

• making a combined sum of two columns

  - by bsandrabr

  I have a table (apples) containing: cid date_am date_pm ---------------------- 1 1 1 2 2 1 3 1 3 1 1 2 I asked a question earlier (badly) about how I would rank the customers in order of the number of ones(1) they had. The solution was (based on one column): SELECT cid, sum( date_pm ) AS No_of_ones FROM apples WHERE date_am =1 GROUP BY cid ORDER BY no_of_ones DESC This works great for one column but how would I do the same for the sum of the two columns. ie. SELECT cid, sum( date_pm ) AS No_of_ones FROM apples WHERE date_am =1 add to SELECT cid, sum( date_am ) AS No_of_ones FROM apples WHERE date_pm =1 GROUP by cid ORDER by no_of_ones(added) hope I've managed to make that clear enough for you to help -thanks

• Can't create a MySQL query that generates 4 rows for each row in the table it references.

  - by UkraineTrain

  I need to create a MySQL query that generates 4 rows for each row in the table it references. I need some of the information in those rows to repeat and some to be different. In the table each row stands for one day. I need to break the day up in 6 hour increments, hence the four rows for each entry. I need to create one column which for each day will have '12AM', '6AM', '12PM', and '6PM' values and another column will have the corresponding numeric values calculated for those entries. Thanks a lot in advance and I will really appreciate any help on this.

• RoR model field without validators, has*, delegates, etc

  - by jackr

  How can I declare a field, in the Rails model, when it doesn't have any "has_" relations, or validations, or delegations? I just need to ensure its existence and column width in the schema. Currently, I have no mention of the field in the "schema section" of the model file, but it's referenced in various methods that use it, and this seems to work. However, depending on my exact creation workflow, the underlying database table may be created as t.binary "field_name", :limit => 32 or t.binary "field_name", :limit => 255 This is not a restriction on the value (any binary value is valid, even NULL), only on the table column declaration. As it happens, 32 is enough -- it never receives any larger value, it's only ever written to like this: self.field_name = SecureRandom.random_bytes(32)

• Convert Military time to string representation

  - by RRUZ

  I have an column declarated as int (called HourMil) wich store the time in military format. i need convert this values to an formated string (HH:MM) example HourMil = 710 -> must be 07:10 HourMil = 1305 -> must be 13:05 Actually i am using this code (and works ok) for convert the column HourMil to the string representation. SELECT SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),1,2)+':'+SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),3,2) FROM MYTABLE but I think this code can be improved.

• Excel PivotTable : Calculated Field / Item for Period Comparison

  - by dino76

  HI All, If I have a PivotTable in Excel 2007 with a date field. I understand that I can group the date by day, month or even year using Group Field (Years & Months). If I combine with product perspective, the PivotTable may look like this Sum of Sales_Total | Column Labels Row Labels | PRODUCT-001 | PRODUCT-002 | Grand Total - 2006 | 2000 | 1500 | 3500 Jan | 1700 | 800 | 2500 Feb | 300 | 700 | 1000 - 2007 | 1000 | 1500 | 2500 Jan | 700 | 800 | 1500 Feb | 300 | 700 | 1000 - 2008 | 600 | 700 | 1300 Jan | 600 | 700 | 1300 Now, what I want to do is to compare Jan 2008 - Jan 2006 and Jan 2007 - Jan 2006. Something like this : | Column Labels | PRODUCT-001 | | ... Row Labels | Sum of Sales | Sum of Last Sales | - 2006 | 2000 | | Jan | 1700 | | Feb | 300 | | - 2007 | 1000 | 2000 | Jan | 700 | 1700 | Feb | 300 | 300 | - 2008 | 600 | 1000 | Jan | 600 | 700 | Is it possible ? If so, how to do that ? Thanks, D. Chopins

• How do I resolve this scope issue in VB .NET?

  - by froadie

  I have a code structure something like this: For row = 1 To numRows Dim arrayIndex As Integer = 0 For column As Integer = bucketStartColumn To bucketEndColumn ' whatever code arrayIndex = arrayIndex + 1 Next Next Dim arrayIndex As Integer = 0 For column As Integer = bucketStartColumn To bucketEndColumn ' whatever code arrayIndex = arrayIndex + 1 Next Not exactly the code, so I don't really need suggestions about refactoring, but my problem is this - with this code I get a compiler error for the first Dim arrayIndex As Integer = 0 - "Variable 'arrayIndex' hides a variable in an enclosing block." As far as I can tell, arrayIndex is local to the first for loop and shouldn't exist by the time we reach the second loop. If I try to change the second declaration of arrayIndex to arrayIndex = 0, I get the error "Name 'arrayIndex' is not declared", as I expected. So is it visible, or not? Does this have something to do with the Dim keyword? Any suggestions of how to get around this, other than naming the second index variable something else?

  Hi, I'm doing a gridview with an object datasource: List<MyObject> TheSource = a linq query At some point, I have MyGridview.DataSource = TheSource; MyGridview.Databind(); and an OnRowDataBound event handler that's tied to the databinding. In that event handler, how do you make column 2 contain 2 objects from TheSource. For instance, in the TheSource, there is a variable for FirstName and another one for LastName. Column 2 needs to contain both the first and last name in the same cell. Thanks.

• PreparedStatement and setTimestamp in oracle jdbc

  - by Roman

  Hi everyone, I am using PreparedStatement with Timestamp in where clause: PreparedStatement s=c.prepareStatement("select utctimestamp from t where utctimestamp>=? and utctimestamp<?"); s.setTimestamp(1, new Timestamp(1273017600000L)); //2010-05-05 00:00 GMT s.setTimestamp(2, new Timestamp(1273104000000L)); //2010-05-06 00:00 GMT The result I get is different, when I have different time zones on the client computer. Is this a bug in Oracle jdbc? or correct behavior? The parameter is Timestamp, and I expected that no time conversions will be done on the way. The database column type is DATE, but I also checked it with TIMESTAMP column type with the same results. Is there a way to achieve correct result? I cannot change default timezone in the the whole application to UTC. Thanks for your help

• How to select the range for pasting using vba

  - by user1616384

  I wrote some code for selecting the particular row and pasting it in column wise using paste-special property. It is working correctly my code is : lngRow = Me.TextBox4.Value strCol = Me.TextBox5.Value Set rng = Range("A:A").Find(What:=lngRow, LookIn:=xlValues, LookAt:=xlWhole) If rng Is Nothing Then MsgBox "Value not found in row 1", vbExclamation Else Range(rng, rng.End(xlToRight)).Copy Range("A1:E3").Columns(strCol).Offset(, 1).PasteSpecial Transpose:=True Range("A1:E3").Rows(1).Copy Range("A1:E3").Columns(strCol).PasteSpecial Transpose:=True endif the problem here is I am using Range(rng, rng.End(xlToRight)).Copy to copy the values and for pasting I am using Range("A1:E3").Columns(strCol).Offset(, 1).PasteSpecial Transpose:=True. How can I paste all the values which are copied? Because if the values are in column F then this macro will not paste those values.

• Basic Hibernate question using and sql query

  Hello Sorry if this is basic but I cannot find the solution anywhere. I have an java Object ‘Person’ with 3 properties firstname,lastname and username. I have an Oracle Store procedure returning a Resultset with the 3 column. All works fine for that. Now I have another StoreProcedure that will only return firstname and lastname but not username. I get the following error : « could not read column value from result set username. » Hibernate tries to fetch the username property from the resultset. If I remove the property username, then it works. Do I have to Create a Special Pojo for Each type of resultset or can I tell Hibernate what to map for each result set? Please help.

• Java long task - Did it stop writing to file?

  - by rockit

  I am writing a lot of data to a file, and while keeping my eye on the file it eventually stopped growing in size. Essentially my task is getting information from a database, and printing out all non-unique values in column A. Since there are many rows to the database table, and the database table is across my network, this is taking days to complete. Thus I'm concerned that since the file isn't growing, that it isn't actually writing to the file anymore. Which is odd, I have no "catch"'s in my code, so if there was a problem writing to file, wouldn't it have thrown an error?! Should I let the task complete (estimate 2-3 days from today), or is there something else that I don't know going on here making my application not write to the file?! my algorithm goes something like this Declare file Create new file Open file for writing get database connection get resultset from database for each row in the resultset - write column "A" to file - if row# % 100000 then write to screen "completed " + row# + " rows" when no more rows exist close file write to screen - "completed"

• Using stored procedures to generate RDLC report in C#

  - by NDraskovic

  I'm making an application that generates reports for my client. I'm using his database that contains stored procedures which return the data needed for the reports. The problem is that I don't know how to execute them from the application (more specific the TableAdapter in my dataset). When I use the visual aid to create the TableAdapter, it shows the error "Invalid object named #table1". This is weird because there is a temporary table called #table1 in the stored procedure. When I try to do the whole job programmatically, I get the exception Incorrect syntax near '.'. An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Change the alias to a valid name. I created a DataTable that has identical structure as the result of the stored procedure, but I still get the same exception
