Statement Class getBfile() getBlob() getBytes() Get the value of a BFILE parameter as a Bfile object. Returns the parameter value. Syntax Bfile getBfile(unsigned int paramIndex); Parameters paramIndex The first parameter is 1, the second is 2, . . . . Get the value of a BLOB parameter as a Blob. Returns the parameter value Syntax Blob getBlob(unsigned int paramIndex); Parameters paramIndex The first parameter is 1, the second is 2, . . . . Get the value of a SQL BINARY or VARBINARY parameter as Bytes. Returns the parameter value; if the value is SQL null, the result is null. Syntax Bytes getBytes(unsigned int paramIndex); Parameters paramIndex The first parameter is 1, the second is 2, . . . . 8-176 Oracle C++ Call Interface Programmer’s Guide
getCharSet() getClob() getConnection() Statement Class Returns the character set that is in effect for the specified parameter, as a string. Syntax string getCharSet(unsigned int paramIndex) const; Parameters paramIndex The first parameter is 1, the second is 2, . . . . Get the value of a CLOB parameter as a Clob. Returns the parameter value. Syntax Clob getClob(unsigned int paramIndex); Parameters getCurrentIteration() paramIndex The first parameter is 1, the second is 2, . . . . Syntax const Connection* getConnection() const; If the prepared statement has any output Streams, this method returns the current iteration of the statement that is being processed by OCCI. If this method is called after all the invocations in the set of iterations has been processed, it returns 0. Returns the iteration number of the current iteration that is being processed. The first iteration is numbered 1 and so on. If the statement has finished execution,a0is returned. OCCI Classes and Methods 8-177
