# bug#1644: Insertion of more than 3 NULL columns with parameter binding fails
|
|
|
|
# Using prepared statements, insertion of more than three columns with NULL
|
|
# values fails to insert additional NULLS. After the third column NULLS will
|
|
# be inserted into the database as zeros.
|
|
# First insert four columns of a value (i.e. 22) to verify binding is working
|
|
# correctly. Then Bind to each columns bind parameter an is_null value of 1.
|
|
# Then insert four more columns of integers, just for sanity.
|
|
# A subsequent select on the server will result in this:
|
|
# mysql> select * from foo_dfr;
|
|
# +------+------+------+------+
|
|
# | col1 | col2 | col3 | col4 |
|
|
# +------+------+------+------+
|
|
# | 22 | 22 | 22 | 22 |

|
# | NULL | NULL | NULL | 0 |
|
|
# | 88 | 88 | 88 | 88 |
|
|
# +------+------+------+------+

|
|
# Test is extended to more columns - code stores bit vector in bytes.
