15   Description
16       Prepares the SQL query.
17
18   Parameter
19       • stmt  -  a  statement  handle,  which  was  previously  allocated  by
20         mysql_stmt_init(3).
21
22       • query - SQL statement
23
24       • length - length of SQL statement
25
26   Return value
27       Zero on success, non zero on error.

29   Notes
30       • The parameter markers must be bound to  application  variables  using
31         mysql_stmt_bind_param(3).
32
33       • The maximum number of parameters is 65535 (0xFFFF).
34
35       • The  markers are legal only in certain places in SQL statements.  For
36         example, they are allowed in the VALUES() list ofINSERT statement (to
37         specify column values for a row), or in a comparison with a column in
38         a [select()](WHERE]] clause to specify a comparison value.   However,
39         they  are  not allowed in identifiers (such as table or column names)
40         in the select list that names the columns to be  returned  by  SELECT
41         statement,  or  to specify both operands of a binary operator such as
42         the equal sign.  The latter restriction is necessary because it would
43         be  impossible  to determine the parameter type.  In general, parame‐
44         ters are legal only in Data Manipulation Language  (DML)  statements,
45         and not in Data Definition Language (DDL) statements.
