Hi, question is that sqlplus return an errorcode only if there are a connection issue, else in every case return 0.
A simple solution is to redirect the output to a tmp file and check the content:

rmvb
rmvb(9F) Kernel Functions for Drivers rmvb(9F)NAME
rmvb - remove a message block from a message
SYNOPSIS
#include <sys/stream.h>
mblk_t *rmvb(mblk_t *mp, mblk_t *bp);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
mp Message from which a block is to be removed. mblk_t is an instance of the
msgb(9S) structure.
bp Message block to be removed.
DESCRIPTION
rmvb() removes a message block (bp) from a message (mp), and returns a pointer to the altered message. The message block is not freed,
merely removed from the message. It is the module or driver's responsibility to free the message block.
RETURN VALUES
If successful, a pointer to the message (minus the removed block) is returned. The pointer is NULL if bp was the only block of the message
before
rmvb() was called. If the designated message block (bp) does not exist, -1 is returned.
CONTEXT
rmvb() can be called from user or interrupt context.
EXAMPLES
This routine removes all zero-length M_DATA message blocks from the given message. For each message block in the message, save the next
message block (line 10). If the current message block is of type M_DATA and has no data in its buffer (line 11), then remove it from the
message (line 12) and free it (line 13). In either case, continue with the next message block in the message (line 16).
