It is important to use Direction property of Oracle Parameter in LOB operations. Input Oracle Command writes data to a server, if Direction is Parameter Direction. In this case Oracle automatically converts LONG and LONG ROW values to CLOB or BLOB data.
dot Connect for Oracle supports all three datatypes. Execute Non Query() & " rows affected.") Finally my Connection. Open() Dim my Reader As Oracle Data Reader = & _ my Command. Create) Dim w As Binary Writer = New Binary Writer(fs) w. Get Ordinal("Pic Name")) Dim fs As File Stream = New File Stream("D:\Tmp\" FN ".bmp", File Mode. If you need raw data however you can use streaming capabilities of Oracle Lob, that is Oracle Lob. Input and assign it with required data prior to actual call to stored procedure. At the same time set Direction property for parameter of Lob data type to Parameter Direction. Dim ora Command As Oracle Command = new Oracle Command( _ "SELECT * FROM Clob Table", ora Connection) Dim reader As Oracle Data Reader = ora Command.
Execute Reader() Dim clob As Oracle Lob while (reader. Concat(FN, " downloaded.")) End If End While Finally my Reader. Close() End Try End Sub Working with CLOB data generally is same as working with BLOB data. If you need to perform simple tasks like fetch record set in most cases you do not need to know about Oracle Lob. Get Value on fetch you get array of bytes for BLOB column and string for CLOB one. Oracle Command ora Command = new Oracle Command("SELECT * FROM Clob Table", ora Connection); Oracle Data Reader reader = ora Command. The following example is part of the Oracle LOB Examples Collection.This example provides two PL/SQL procedures that demonstrate how to populate a CLOB column with a text file (an XML file) then write it back out to the file system as a different file name. Dim sql As string = "UPDATE Clob Table SET Name = : Name, Value = EMPTY_CLOB() & _ WHERE Id = : Id RETURNING Value INTO : Value" Dim ora Command As Oracle Command = new Oracle Command(sql, ora Connection) ora Command.
