Here follows a list of the currently known problems with prepared statements:
- TIME,- TIMESTAMP, and- DATETIMEdo not support parts of seconds (for example, from- DATE_FORMAT()).
- When converting an integer to string, - ZEROFILLis 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 do not support multi-statements (that is, multiple statements within a single string separated by - ;characters).
- The capabilities of prepared - CALLstatements are described in Section 3.6.5, “Prepared CALL Statement Support”.
