OCIDefineByName

Description

OCIDefineByName() uses fetches SQL-Columns into user-defined PHP-Variables. Be careful that Oracle user ALL-UPPERCASE column-names, whereby in your select you can also write lower-case. OCIDefineByName() expects the Column-Name to be in uppercase. If you define a variable that doesn't exists in you select statement, no error will be given!

If you need to define an abstract Datatype (LOB/ROWID/BFILE) you need to allocate it first using OCINewDescriptor() function. See also the OCIBindByName() function.
