Simple .NET/ASP.NET PDF document editor web control SDK

For example, the following code defines a simple managed UDF that returns a single full name from a given title, first name, middle name, and last name [SqlFunction()] public static SqlString GetFullName(SqlString title, SqlString first, SqlString middle, SqlString last) { StringBuilder fullName = new StringBuilder(); if (!titleIsNull) { fullNameAppendFormat("{0} ", title); } fullNameAppendFormat("{0} ", first); if (!middleIsNull) { fullNameAppendFormat("{0} ", middle); } fullNameAppend(last); return fullNameToString(); }.

Because oftentimes you place initialization or cross-page posting code in a page event (typically for the Load event), you need to make sure that this code is executed only for initialization or when data is being posted to the page You can do so by checking the IsPostBack property of the Page object, which returns false if the page is requested the first time..

import oracle.sql.ArrayDescriptor; import oracle.sql.ARRAY; import oracle.sql.Datum; import oracle.sql.NUMBER; import oracle.sql.CHAR; import book.util.JDBCUtil; import book.util.Util; class DemoQueryingCollectionOfBuiltInTypes { The main() method first invokes two functions passing the Connection object. The method _doSelectVarchar2Array() returns an ARRAY of varchar2 elements, whereas the method _doSelectNumberArray() returns an ARRAY of number elements. These two methods are explained along with their definitions as part of this listing. The method _printArrayInfo(), invoked once each for the two returned arrays, is used to print information about the passed array object as you will see shortly. public static void main(String args[]) throws Exception { Util.checkProgramUsage( args ); Connection conn = null; try { conn = JDBCUtil.getConnection("benchmark", "benchmark", args[0]); ARRAY varcharArray = _doSelectVarchar2Array( conn ); ARRAY numberArray = _doSelectNumberArray(conn ); _printArrayInfo( varcharArray ); _printArrayInfo( numberArray ); } finally { // release JDBC resources JDBCUtil.close( conn ); } } Retrieving a Collection of Varchar2 Elements The method _doSelectVarchar2Array() demonstrates how to retrieve members of a collection of varchar2 elements from a table. private static ARRAY _doSelectVarchar2Array( Connection conn ) throws SQLException { PreparedStatement pstmt = null; ResultSet rset = null; ARRAY array = null; try {

As the first step, we prepare the statement that selects the varray column of varchar2 elements from the table varchar_varray_table We then execute the statement and obtain the ResultSet: String stmtString = "select varray_column from varchar_varray_table"; pstmt = connprepareStatement( stmtString ); // Step 2 - execute the statement and get the result set rset = pstmtexecuteQuery(); while( rsetnext() ) { We then use the getArray() method of the ResultSet interface to retrieve the array Note that alternatively we could have used the Oracle extension method getARRAY(), also in the interface OracleResultSet That makes your code ever so slightly more dependent on the Oracle proprietary interface; otherwise, there is no difference between the two methods array =( ARRAY ) rsetgetArray(1); The methods _doUseGetArray(), _doUseResultSet(), and _doUseGetOracleArray() use the methods getArray() of the Array interface, getResultSet() of the Array interface, and getOracleArray() of the ARRAY class, respectively.

type SchemaReader<'schema> = new : unit -> SchemaReader<'schema> member ReadFile : string -> seq<'schema> member ReadLine : System.IO.TextReader -> 'schema First we show how the SchemaReader is used in practice. Let s say you have a text file containing lines such as this: Steve, 12 March 2007, Cheddar Sally, 18 Feb 2007, Brie ... Now it s reasonable to want to convert this data to a typed data representation. You can do this simply by defining an appropriate record type along with enough information to indicate how the data in the file maps into this type. This information is expressed using custom attributes, which are a way to add extra meta-information to assembly, type, member, property, and parameter definitions. Each custom attribute is specified as an instance of a typed object, here ColumnAttribute, defined in Listing 9-10. The suffix Attribute can be dropped when using the custom attribute. type CheeseClub = { [<Column(0)>] Name : string [<Column(2)>] FavouriteCheese : string [<Column(1)>] LastAttendance : System.DateTime } You can now instantiate the SchemaReader type and use it to read the data from the file into this typed format: > let reader = new SchemaReader<CheeseClub>();; val reader : SchemaReader<CheeseClub> > fsi.AddPrinter(fun (c:System.DateTime) -> c.ToString());; val it : unit = () > System.IO.File.WriteAllLines("data.txt", [| "Steve, 12/03/2007, Cheddar"; "Sally, 18/02/2007, Brie"; |]);; val it : unit = () > reader.ReadFile("data.txt");; val it : seq<CheeseClub> = seq [{Name = "Steve"; FavouriteCheese = "Cheddar"; LastAttendance = 12/03/2007 00:00:00;}; {Name = "Sally"; FavouriteCheese = "Brie"; LastAttendance = 18/02/2007 00:00:00;}]
