# The old multiquery implementation uses '\n' to split INSERT query segmentation
|
|
# this case is mainly to test the following situations
|
|
# 1. INSERT(format=Values) query: split by ';'
|
|
# 2. INSERT(format is not Values) query: split by '\n\n' instead of ';', then discard the ramaining data
|
|
# 3. INSERT(format is not Values) query: split by '\n\n', causing the trailing ';'' to be treated as the part of last value
|
|
# 4. The client uses multiquery by default, regardless of whether multiquery option is used.

# create table test1, test2, then
|
|
# 1. insert 101, 102 into test1
|
|
# 2. insert 1, 2; into test2, ';' will be treated as a part of a value
|
|
# 3. insert 3, 4; '6' will be treated as the next query because of the empty line, we use empty line to determine the end of insert query(format IS NOT VALUES)
|
|
# '6' will cause Syntax error
