#*********************************************************************
# Description:
# It is also possible to retrieve meta information about
results.
# sasql_fetch_field() returns an object that contains column
# properties of a result set.
#
# The
sample code fetches meta information about a result using
# sasql_fetch_field() and fetches the row using sasql_fetch_row().
#
#*********************************************************************
# Connect using the default user ID
and password
$conn =sasql_connect ( "UID=DBA;PWD=sql" ) ;
if
( ! $conn ) {
die ( "Connection
failed" ) ;
} else {
#
Connected successfully.
#
Execute a SELECT statement
$result =sasql_query ( $conn
, "SELECT * FROM Customers" ) ;
if ( ! $result )
{
echo
"sasql_query failed!" ;
return 0 ;
} else {
echo
"query completed successfully \n " ;
}
#
Retrieve meta information about the results
$num_cols =sasql_num_fields ( $result )
;
$num_rows =sasql_num_rows ( $result )
;
echo "Num of rows
= $num_rows \n "
;
echo "Num of cols
= $num_cols \n "

all the rows
