Chapter 19 C API Prepared Statement Problems

Here follows a list of the currently known problems with prepared statements:

TIME, TIMESTAMP, and DATETIME do not support parts of seconds (for example, from DATE_FORMAT()).
When converting an integer to string, ZEROFILL is honored with prepared statements in some cases where the MySQL server does not print the leading zeros. (For example, with MIN(number-with-zerofill)).
When converting a floating-point number to a string in the client, the rightmost digits of the converted value may differ slightly from those of the original value.
Prepared statements use the query cache under the conditions described in How the Query Cache Operates.
Prepared statements do not support multi-statements (that is, multiple statements within a single string separated by ; characters).
The capabilities of prepared CALL statements are described in Chapter 18, C API Prepared CALL Statement Support.
