This instance method compares data referenced by the current instance to that of the supplied object.

Declaration

// C#
public int Compare(Int64 src_offset, OracleClob obj, Int64 dst_offset, 
   Int64 amount);

Parameters

• src_offset

  The comparison starting point (in characters) for the current instance.

• obj

  The provided OracleClob object.

• dst_offset

  The comparison starting point (in characters) for the provided OracleClob.

• amount

  The number of characters to compare.

Return Value

The method returns a value that is:

• Less than zero: if the data referenced by the current instance is less than that of the supplied instance.

• Zero: if both objects reference the same data.

• Greater than zero: if the data referenced by the current instance is greater than that of the supplied instance.

Exceptions

ObjectDisposedException - The object is already disposed.

InvalidOperationException - The parameter has a different connection than the object, OracleConnection is not opened, or OracleConnection has been reopened.

ArgumentOutOfRangeException - Either the src_offset, dst_offset, or amount parameter is less than 0.

Remarks

The character set of the two OracleClob objects being compared should be the same for a meaningful comparison.

The provided object and the current instance must be using the same connection, that is, the same OracleConnection object.
