  • Table for each region in MySQL

    - by King Wu
    There are four regions with more than one million records total. Should I create a table with a region column or a table for each region and combine them to get the top ranks? If I combine all four regions, none of my columns will be unique so I will need to also add an id column for my primary key. Otherwise, name, accountId & characterId would be candidate keys or should I just add an id column anyways. Table: ---------------------------------------------------------------- | name | accountId | iconId | level | characterId | updateDate | ----------------------------------------------------------------

  • SQL - First row inserted every day for the past X days

    - by okie.floyd
    A tough SQL question (I'm using postgres by the way). I need the first row inserted every day for the past X days. one of my columns is a timestamp, which i hold the time inserted, and another column is the row id. If it's not possible to get the first row inserted every day, i at least need a unique one; a single row for every day for the past x days. Any suggestions? Thanks okie

  • Multi-Column Primary Key in MySQL 5

    - by Kaji
    I'm trying to learn how to use keys and to break the habit of necessarily having SERIAL type IDs for all rows in all my tables. At the same time, I'm also doing many-to-many relationships, and so requiring unique values on either column of the tables that coordinate the relationships would hamper that. How can I define a primary key on a table such that any given value can be repeated in any column, so long as the combination of values across all columns is never repeated exactly?

  • Finding a Identity Specification using SQL

    Good Morning, I have an MS SQL database, of which there is a column that has an identity specification. However, if I do a SQL query such as: SELECT * FROM INFORMATION_SCHEMA.Columns where TABLE_NAME = It doesn't tell me if the column is an identity specification - is there a query that will? Many Thanks, Joel

  • Convert byte to boolean string in HyperLinkField.DataNavigateUrlFormatString

    - by abatishchev
    I have a asp:GridView with a HyperLinkField. It's DataNavigateUrlFormatString property is set to View.aspx?id={0}&isTechnical={1} Select command of appropriate SqlDataSource returns columns of type INT and BYTE (from SQL Server 2008). So displayed string becomes something like View.aspx?id=1&isTechnical=1. But I want to display isTechnical=true|False, i.e. Convert.ToBoolean(row["isTechnical"]).ToString().ToLowerInvariant(). How to implement such conversion in page markup?

  • ASP.Net / MySQL : Translating content into several languages

    - by philwilks
    I have an ASP.Net website which uses a MySQL database for the back end. The website is an English e-commerce system, and we are looking at the possibility of translating it into about five other languages (French, Spanish etc). We will be getting human translators to perform the translation - we've looked at automated services but these aren't good enough. The static text on the site (e.g. headings, buttons etc) can easily be served up in multiple languages via .Net's built in localization features (resx files etc). The thing that I'm not so sure about it how best to store and retrieve the multi-language content in the database. For example, there is a products table that includes these fields... productId (int) categoryId (int) title (varchar) summary (varchar) description (text) features (text) The title, summary, description and features text would need to be available in all the different languages. Here are the two options that I've come up with... Create additional field for each language For example we could have titleEn, titleFr, titleEs etc for all the languages, and repeat this for all text columns. We would then adapt our code to use the appropriate field depending on the language selected. This feels a bit hacky, and also would lead to some very large tables. Also, if we wanted to add additional languages in the future it would be time consuming to add even more columns. Use a lookup table We could create a new table with the following format... textId | languageId | content ------------------------------- 10 | EN | Car 10 | FR | Voiture 10 | ES | Coche 11 | EN | Bike 11 | FR | Vélo We'd then adapt our products table to reference the appropriate textId for the title, summary, description and features instead of having the text stored in the product table. This seems much more elegant, but I can't think of a simple way of getting this data out of the database and onto the page without using complex SQL statements. Of course adding new languages in the future would be very simple compared to the previous option. I'd be very grateful for any suggestions about the best way to achieve this! Is there any "best practice" guidance out there? Has anyone done this before?

  • How to pass a variable to an awk print parameter...

    - by Jamie
    I'm trying extract the nth + 1 and nth + 3 columns from a file. This is what tried, which is a useful pseudo code: for i in {1..100} ; do awk -F "," " { printf \"%3d, %12.3f, %12.3f\\n\", \$1, \$($i+1), \$($i+3) } " All_Runs.csv > Run-$i.csv which, obviously doesn't work (but it seemed reasonable to hope). How can I do this?

  • Problem with skipping empty cells while importing data from .xlsx file in asp.net c# application

    - by Eedoh
    Hi to all. I have a problem with reading .xlsx files in asp.net mvc2.0 application, using c#. Problem occurs when reading empty cell from .xlsx file. My code simply skips this cell and reads the next one. For example, if the contents of .xlsx file are: FirstName LastName Age John 36 They will be read as: FirstName LastName Age John 36 Here's the code that does the reading. private string GetValue(Cell cell, SharedStringTablePart stringTablePart) { if (cell.ChildElements.Count == 0) return string.Empty; //get cell value string value = cell.ElementAt(0).InnerText;//CellValue.InnerText; //Look up real value from shared string table if ((cell.DataType != null) && (cell.DataType == CellValues.SharedString)) value = stringTablePart.SharedStringTable.ChildElements[Int32.Parse(value)].InnerText; return value; } private DataTable ExtractExcelSheetValuesToDataTable(string xlsxFilePath, string sheetName) { DataTable dt = new DataTable(); using (SpreadsheetDocument myWorkbook = SpreadsheetDocument.Open(xlsxFilePath, true)) { //Access the main Workbook part, which contains data WorkbookPart workbookPart = myWorkbook.WorkbookPart; WorksheetPart worksheetPart = null; if (!string.IsNullOrEmpty(sheetName)) { Sheet ss = workbookPart.Workbook.Descendants<Sheet>().Where(s => s.Name == sheetName).SingleOrDefault<Sheet>(); worksheetPart = (WorksheetPart)workbookPart.GetPartById(ss.Id); } else { worksheetPart = workbookPart.WorksheetParts.FirstOrDefault(); } SharedStringTablePart stringTablePart = workbookPart.SharedStringTablePart; if (worksheetPart != null) { Row lastRow = worksheetPart.Worksheet.Descendants<Row>().LastOrDefault(); Row firstRow = worksheetPart.Worksheet.Descendants<Row>().FirstOrDefault(); if (firstRow != null) { foreach (Cell c in firstRow.ChildElements) { string value = GetValue(c, stringTablePart); dt.Columns.Add(value); } } if (lastRow != null) { for (int i = 2; i <= lastRow.RowIndex; i++) { DataRow dr = dt.NewRow(); bool empty = true; Row row = worksheetPart.Worksheet.Descendants<Row>().Where(r => i == r.RowIndex).FirstOrDefault(); int j = 0; if (row != null) { foreach (Cell c in row.ChildElements) { //Get cell value string value = GetValue(c, stringTablePart); if (!string.IsNullOrEmpty(value) && value != "") empty = false; dr[j] = value; j++; if (j == dt.Columns.Count) break; } if (empty) break; dt.Rows.Add(dr); } } } } } return dt; }

  • Oracle: Is there a way to get the column data types for a view?

    - by rally25rs
    For a table in oracle, I can query "all_tab_columns" and get table column information, like the data type, precision, whether or not the column is nullable. In SQL Developer or TOAD, you can click on a view in the GUI and it will spit out a list of the columns that the view returns and the same set of data (data type, precision, nullable, etc). So my question is, is there a way to query this column definition for a view, the way you can for a table? How do the GUI tools do it?

  • Get highlighted state for NSButtonCell

    - by dvg
    I have a NSTableView that contains a NSButtonCell in one of the columns. To draw a custom background in neighbor cells (based on NSTextFieldCell) I use isHighlighted method: - (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView { if ([self isHighlighted]) { //here I draw the cell background But for NSButtonCell isHighlighted shows only the button pressed state. How to determine when the NSButtonCell is selected, i.e. when it's highlighted in the row?

  • Improve SQL Server 2005 Query Performance

    - by user366810
    I have a course search engine and when I try to do a search, it takes too long to show search results. You can try to do a search here http://76.12.87.164/cpd/testperformance.cfm At that page you can also see the database tables and indexes, if any. I'm not using Stored Procedures - the queries are inline using Coldfusion. I think I need to create some indexes but I'm not sure what kind (clustered, non-clustered) and on what columns. Thanks
