I am finding the documentation located at http://www.mysql.com/doc/en/C_API_Prepared_statement_datatypes.html on the C API Prepared Statement Interface to be a bit unclear.
In the MYSQL_BIND datatype, when using mysql_bind_param() and mysql_excute() to pass parameters to a prepared statment, how does one specify the length of the parameters that will be passed? There are two fields, buffer_length and length, both of are documented to specify the length of input arguments. For buffer_length we have: "For character and binary C data, the buffer_length value specifies the length of *buffer when used with mysql_bind_param()." In turn for length we have "For input parameter data binding, length points to an unsigned long variable that indicates the length of the parameter value stored in * buffer; this is used by mysql_execute()" One might conclude that mysql_bind_param() uses buffer_length to tell the server about the max argument length, and that mysql_execute() uses length to decide how much data to actually send for a given invocation. Is this correct? Thanks, Richard Tibbetts -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
