For example, if you request 20,000 records from a table to store in a text file, it would be rather memory-intensive to hold this information in a DataSet (because a DataSet holds the entire result of the query in memory at the same time) A better approach is to create a data reader that spins over each record as rapidly as possible Be aware, however, that data reader objects (unlike data adapter objects, which you ll examine later) maintain an open connection to their data source until you explicitly close the connection You obtain data reader objects from the command object using a call to ExecuteReader()The data reader represents the current record it has read from the database The data reader has an indexer method (eg, [] syntax in C#) that allows you to access a column in the current record. .net core qr code generator codebude/QRCoder: A pure C# Open Source QR Code ... - GitHub

You can access the column either by name or by zero-based integer The following use of the data reader leverages the Read() method to determine when you have reached the end of your records (using a false return value) For each incoming record that you read from the database, you use the type indexer to print out the make, pet name, and color of each automobile Also note that you call Close() as soon as you finish processing the records; this frees up the connection object: static void Main(string[] args) { .. // Obtain a data reader via ExecuteReader() using(SqlDataReader myDataReader = myCommandExecuteReader()) { // Loop over the results while (myDataReaderRead()). .net core qr code generator .NET Standard and .

20 Set 2018 ... Desta vez, vamos costurar umas palavras sobre como gerar QR Codes no ASP. NET CORE utilizando bibliotecas instaladas via nuget. Bora lá ... { Console.WriteLine("-> Make: {0}, PetName: {1}, Color: {2}.", myDataReader["Make"].ToString(), myDataReader["PetName"].ToString(), myDataReader["Color"].ToString()); } } Console.ReadLine(); } In the preceding snippet, you overload the indexer of a data reader object to take either a string (representing the name of the column) or an int (representing the column s ordinal position). Thus, you can clean up the current reader logic (and avoid hard-coded string names) with the following update (note the use of the FieldCount property): while (myDataReader.Read()) { Console.WriteLine("***** Record *****"); for (int i = 0; i < myDataReader.FieldCount; i++) { Console.WriteLine("{0} = {1} ", myDataReader.GetName(i), myDataReader.GetValue(i).ToString()); } Console.WriteLine(); } If you compile and run your project at this point, you should see a list of all automobiles in the Inventory table of the AutoLot database. The following output shows the initial few records from my own version of AutoLot: ***** Fun with Data Readers ***** ***** Info about your connection ***** Database location: (local)\SQLEXPRESS Database name: AutoLot Timeout: 30 Connection state: Open ***** Record ***** CarID = 83 Make = Ford Color = Rust PetName = Rusty ***** Record ***** CarID = 107 Make = Ford Color = Red PetName = Snake Data reader objects can obtain multiple result sets using a single command object. For example, if you want to obtain all rows from the Inventory table, as well as all rows from the Customers table, you can specify both SQL select statements using a semicolon delimiter: string strSQL = "Select * From Inventory;Select * from Customers"; Once you obtain the data reader, you can iterate over each result set using the NextResult() method. Note that you are always returned the first result set automatically. Thus, if you wish to read over the rows of each table, you can build the following iteration construct: do { while (myDataReader.Read()) { Console.WriteLine("***** Record *****"); for (int i = 0; i < myDataReader.FieldCount; i++) { Console.WriteLine("{0} = {1}", myDataReader.GetName(i), myDataReader.GetValue(i).ToString()); } Console.WriteLine(); } } while (myDataReader.NextResult()); At this point, you should be more aware of the functionality data reader objects bring to the table. Always remember that a data reader can only process SQL Select statements; you cannot use them to modify an existing database table using Insert, Update, or Delete requests. Modifying an existing database requires additional investigation of command objects. The binary large object data (blob) type is used to store binary data (for example, Drupal s cache table to store the cached data). Binary data may include music, images, or video. Two sizes are available, normal and big. $field['fieldname'] = array( 'type' => 'blob', // Required. 'size' => 'normal' // normal | big 'not null' => TRUE, // Defaults to FALSE. 'description' => t('Always state the purpose of your field.'), ); .net core qr code generator QRCoder 1.3.6 - NuGet Gallery
