cniSqlDeletePathExpression
Deletes the SQLPathExpression previously created by the cniSqlCreateReadOnlyPathExpression
or the cniSqlCreateModifiablePathExpression utility functions, as defined
by the sqlPathExpression argument.
A NULL pointer input signifies that the user-defined node does not want
to deal with errors. Any exceptions thrown during the execution of this call
will be re-thrown to the next upstream node in the flow. If input is not NULL,
output will signify the success status of the call. If an exception occurs
during execution, *returnCode will be set to CCI_EXCEPTION on output. A call
to cciGetLastExceptionData will provide details of the exception. If an invalid
sqlPathExpression parameter was passed in, then returnCode will be set to
CCI_INV_SQL_EXPR_OBJECT.
sqlPathExpression (output)
Specifies the SQLPathExpression object to be deleted as returned by one
of the cniCreate[ReadOnly|Modifiable]PathExpression functions. May not be
NULL.
Return values
None. If an error occurs, the returnCode parameter indicates the
reason for the error..
Example
Expanding on the example for cniSqlCreateReadOnlyPathExpression,
you should place the following code in _deleteNodeContext
