mysql_stmt_fetch \- Fetches result set row from a prepared statement
|
|
.SS Synopsis
|
|
.IP
|
|
.nf
|
|
\f[C]
|
|
#include <mysql.h>
|
|
|

|
.SS Description
|
|
.PP
|
|
Fetch the result from a prepared statement into the buffer bound by
|
|
[mysql_stmt_bind_result()}(mysql_stmt_bind_result).
|
|
.SS Parameter
|
|
.IP \[bu] 2
|
|
\f[C]stmt\f[R] \- a statement handle, which was previously allocated by
|
|
\f[B]mysql_stmt_init(3)\f[R].
|
|
.SS Return value
|
|
.PP
|
|
Returns \f[C]0\f[R] for success, \f[C]MYSQL_NO_DATA\f[R] if the end of
|
|
the result set has been reached, or \f[C]MYSQL_DATA_TRUNCATION\f[R] if
|
|
one or more values are truncated.
|
|
.SS Notes
|
|
.IP \[bu] 2
|
|
Note that all columns must be bound by the application before calling
|
|
mysql_stmt_fetch().
|
|
.IP \[bu] 2
|
|
Data are transferred unbuffered without calling
|
|
\f[B]mysql_stmt_store_result(3)\f[R] which can decrease performance (but
|
|
reduces memory cost).
|
|
.IP \[bu] 2
|
|
Truncation reporting must be enabled by function
|
|
\f[B]mysql_optionsv(3)\f[R] with option
|
|
\f[C]MYSQL_REPORT_DATA_TRUNCATION\f[R]
