Steps for creating Database Connections Introduction
(#e D;C / ava Data)ase Connectivity0 API de$ines inter$aces and casses $or writing data)ase appications in ava )y maing data)ase connections. =sing D;C you can send S%&- P&
Loading a database driver
In t#is step o$ t#e ,d)c connection process- we oad t#e driver cass )y caing Cass.$or8ame/0 wit# t#e Driver cass name as an argument. Once oaded- t#e Driver cass creates an instance o$ itse$. A cient can connect to Data)ase Server t#roug# D;C Driver. Since most o$ t#e Data)ase servers support OD;C driver t#ere$ore D;COD;C ;ridge driver is commony used.(#e return type o$ t#e Cass.$or8ame /String Cass8ame0 met#od is MCassN. Cass is a cass in,ava.ang pacage. try ? Class'forName9@sun'jdbc'odbc'%dbcOdbc!ri)er@ ..Or any ot0er dri)er catc09$ception ? System'out'println9 Dnable to load t0e dri)er classE@ 5.2.3
Creating a jdbc Connection
(#e D;C Driver"anager cass de$ines o),ects w#ic# can con nect ava appications to a D;C driver. Driver"anager is considered t#e )ac)one o$ D;C arc#itecture. Driver"anager cass manages t#e D;C drivers t#at are instaed on t#e system. Its getConnection/0 met#od is used to esta)is# a connection to a data)ase. It uses a username- password- and a ,d)c ur to esta)is# a connection to t#e data)ase and returns a connection o),ect. A ,d)c Connection represents a session
5.2.4
Creating a jdbc Statement object
Once a connection is o)tained we can interact wit# t#e data)ase. Connection inter$ace de$ines met#ods $or interacting wit# t#e data)ase via t#e esta)is#ed connection. (o eecute S%& statements- you need to instantiate a Statement o),ect $rom your connection o),ect )y using t#e createStatement/0 met#od. Statement statement d)Connection.createStatement/09 A statement o),ect is used to send and eecute S%& statements to a data)ase. (#ree inds o$ Statements Statement: ecute simpe s5 5ueries wit#out parameters.Statement createStatement/0Creates an S%& Statement o),ect. Prepared Statement: ecute precompied s5 5ueries wit# or wit#out parameters. PreparedStatement prepareStatement/String s50returns a new PreparedStatement o),ect. PreparedStatement o),ects are precompiedS%& statements. Callable Statement: ecute a ca to a data)ase stored procedure.Caa)eStatement prepareCa/String s50returns a new Caa)eStatement o),ect. Caa)eStatement o),ects are S%& stored procedure ca statements.
5.2.5 Executing a SQL statement with the Statement object, and returning a jdbc resultSet.
Statement inter$ace de$ines met#ods t#at are used to interact wit# data)ase via t#e eecution o$ S%& statements. (#e Statement cass #as t#ree met#ods $or eecuting statements6 eecute%uery/0- eecute=pdate/0- and eecute/0. +or a S&C( statement- t#e met#od to use is eecute%uery . +or statements t#at create or modi$y ta)es- t#e met#od to use is eecute=pdate. 8ote6 Statements t#at create a ta)e- ater a ta)e- or drop a ta)e are a eampes o$ DD& statements and are eecuted wit# t#e met#od eecute=pdate. eecute/0 eecutes an S%& statement t#at is written as String o),ect.
