my_bool mysql_stmt_bind_param(MYSQL_STMT *stmt, MYSQL_BIND *bind)
mysql_stmt_bind_param()
is used to
bind input data for the parameter markers in the SQL statement that was passed to mysql_stmt_prepare()
. It uses MYSQL_BIND
structures to supply the data. bind
is the address of an array of MYSQL_BIND
structures. The client library expects the array to contain one
element for each ?
parameter marker that is present in the query.
Suppose that you prepare the following statement:
INSERT INTO mytbl VALUES(?,?,?)
When you bind the parameters, the array of MYSQL_BIND
structures must contain three
elements, and can be declared like this:
MYSQL_BIND bind[3];
Section 22.8.9, "C API Prepared Statement Data
Structures", describes the members of each MYSQL_BIND
element and how they
should be set to provide input values.
Zero if the bind operation was successful. Nonzero if an error occurred.
The conversion is not supported. Possibly the buffer_type
value is
invalid or is not one of the supported types.
Out of memory.
An unknown error occurred.
See the Example in Section 22.8.11.10, "mysql_stmt_execute()
".
