Remarks

If the CacheData property is false, applications can only retrieve the complete set of data from a DB2Clob instance once. Any additional attempts at retrieving data will result in an InvalidOperationException. The specific implications of this are:

This method can only be used to retrieve data from a DB2Clob instance once.
If you use this method to retrieve data from a DB2Clob instance, you cannot use the Value property or the GetChars method to do the same.
If you have already used the Value property or the GetChars method to retrieve data from a DB2Clob instance, you cannot use this method to do the same.

If the CacheData property is true, data can be read from the DB2Clob structure, using any of the access methods.
