Declaration

// C#
public OracleString GetOracleString(int index);

Parameters

• index

  The zero-based column index.

The OracleString value of the column.

Exceptions

InvalidOperationException - The connection is closed, the reader is closed, Read() has not been called, or all rows have been read.

IndexOutOfRangeException - The column index is invalid.

InvalidCastException - The accessor method is invalid for this column type or the column value is NULL.

Remarks

If the column is an Oracle REF column, the string returned is a hexadecimal value that represents the REF in the database.

For VECTOR columns, the string returned is a JSON string that represents the VECTOR in the database. A sparse vector type column will return a JSON string in sparse format.

For ODP.NET managed and core, a JSON formatted string is returned for the cursor result set from Oracle REF CURSOR columns.
