# Test case for Bug#11230

# The point of this test is to make sure that '#', '-- ' and '/* ... */'
# comments, as well as empty lines, are sent from the client to the server.
# This is to ensure better error reporting, and to keep comments in the code
# for stored procedures / functions / triggers (Bug#11230).
# As a result, be careful when editing comments in this script, they do
# matter.
#
# Also, note that this is a script for **mysql**, not mysqltest.
# This is critical, as the mysqltest client interprets comments differently.

##============================================================================
## Setup

## See mysql_comments.test for initial cleanup

# Test tables

# t1 is reused throughout the file, and dropped at the end.
