3.6.5 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 Section 3.6.4, “Prepared CALL Statement Support”.
