maxdb_prepare() prepares the SQL query pointed to by the
null-terminated string query, and returns a statement handle to be used for
further operations on the statement. The query must consist of a single SQL statement.
You should not add a terminating semicolon or \g
to the statement.
The parameter query can include one or more parameter markers
in the SQL statement by embedding question mark (?) characters
at the appropriate positions.
The markers are legal only in certain places in SQL statements.
For example, they are allowed in the VALUES() list of an INSERT statement
(to specify column values for a row), or in a comparison with a column in
a WHERE clause to specify a comparison value.
However, they are not allowed for identifiers (such as table or column names),
in the select list that names the columns to be returned by a SELECT statement),
or to specify both operands of a binary operator such as the =
equal sign. The latter restriction is necessary because it would be impossible
to determine the parameter type. In general, parameters are legal only in Data
Manipulation Languange (DML) statements, and not in Data Defination Language
