Im sorry if this classified as OOT
One example of the confussion
C Header File declaration of statement handler (taken from the 4.1.3)
typedef struct st_mysql_stmt
{
MEM_ROOT mem_root; /* root allocations */
LIST list; /* list to keep track of all stmts */
MYSQL *mysql; /* connection handle */
MYSQL_BIND *params; /* input parameters */
MYSQL_BIND *bind; /* output parameters */
MYSQL_FIELD *fields; /* result set metadata */
MYSQL_DATA result; /* cached result set */
MYSQL_ROWS *data_cursor; /* current row in cached result */
/* copy of
mysql->affected_rows after statement execution */
my_ulonglong affected_rows;
my_ulonglong insert_id; /* copy of mysql->insert_id */
/*
mysql_stmt_fetch() calls this function to fetch one row (it's different
for buffered, unbuffered and cursor fetch).
*/
int (*read_row_func)(struct st_mysql_stmt *stmt,
unsigned char **row);
unsigned long stmt_id; /* Id for prepared statement */
unsigned int last_errno; /* error code */
unsigned int param_count; /* inpute parameters count */
unsigned int field_count; /* number of columns in result set */
enum enum_mysql_stmt_state state; /* statement state */
char last_error[MYSQL_ERRMSG_SIZE]; /* error message */
char sqlstate[SQLSTATE_LENGTH+1];
/* Types of input parameters should be sent to server */
my_bool send_types_to_server;
my_bool bind_param_done; /* input buffers were supplied */
my_bool bind_result_done; /* output buffers were supplied */
/* mysql_stmt_close() had to cancel this result */
my_bool unbuffered_fetch_cancelled;
/*
Is set to true if we need to calculate field->max_length for
metadata fields when doing mysql_stmt_store_result.
*/
my_bool update_max_length;
} MYSQL_STMT;
And the pascal version (taken from Jorge del Conde's)
PMYSQL_STMT = ^TMYSQL_STMT;
TMYSQL_STMT = record
mysql: PMYSQL; // connection handle
params: PMYSQL_BIND; // input parameters
result: PMYSQL_RES; // resultset
bind: PMYSQL_BIND; // row binding
fields: PMYSQL_FIELD; // prepare meta info
list: _TLIST; // list to keep track
of all stmts
query: PChar; // query buffer
mem_root: TMEM_ROOT; // root allocations
param_count: Cardinal; // parameters count
field_count: Cardinal; // fields count
stmt_id: Cardinal; // Id for prepared
statement
last_errno: Cardinal; // error code
state: PREP_STMT_STATE; // statement state
last_error: array [0..MYSQL_ERRMSG_SIZE - 1] of char; // error message
long_alloced: my_bool; // flag to indicate long
alloced
send_types_to_server: my_bool; // Types sent to server
param_buffers: my_bool; // param bound buffers
res_buffers: my_bool; // output bound buffers
result_buffered: my_bool; // Results buffered
end;
I see that the two declarations have different number of total
field/member..
And also some of the struct/record member has different order of placement..
Is it ok for me to add the other missing member??
