Trang 1int mssql_field_seek (int result, int field_offset)
Description
The mssql_field_seek() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, sets the field position in the result set to the
specified offset If the next call to mssql_fetch_field() doesn't include an offset, this field will be returned
mssql_field_type()
Syntax
string mssql_field_type (int result [, int offset)
Description
The mssql_field_type() function, which is available from PHP 3.0.3 to PHP 3.0.16 along with PHP 4.0 and higher, returns the type of a field in the result set at the offset location

Description
The mssql_free_result() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, frees all memory associated with the result set This
will happen automatically at the end of a script's processing, so it is not usually necessary to call this function

Syntax
Trang 2Description
The mssql_get_last_message() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, returns the last message generated from the server
mssql_min_error_severity()
Syntax
void mssql_min_error_severity (int severity)
Description
The mssql_min_error_severity() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, sets the minimum threshold for the errors generated by the server
mssql_min_message_severity()
Syntax
void mssql_min_message_severity (int severity)
Description
The mssql_min_message_severity() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, sets the maximum threshold for the messages generated by the server
mssql_num_fields()
Syntax
int mssql_num_fields (int result)
Description
Trang 3The mssql_num_fields() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, returns the number of fields in the result set
mssql_num_rows()
Syntax
int mssql_num_rows (int result)
Description
The mssql_num_rows() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, returns the number of rows in the result set
mssql_pconnect()
Syntax
int mssql_pconnect (string servername [, string username [, string
password]]])
Description
The mssql_pconnect() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, acts similar to mssql_connect() except that it first looks for a persistent connection that is already established If a persistent connection is available, the function uses it instead of opening a new one Secondly, the connection does not close with the end of a script's processing
mssql_query()
Syntax
int mssql_query (string query [, int link_identifier])
Description
The mssql_query() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, sends a query to the database indicated by the
Trang 4attempt is made as if mssql_connect() were called A result_identifier is
returned on success; otherwise, FALSE is returned
mssql_result()
Syntax
int mssql_result (int result, int i, mixed field)
Description
The mssql_result() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, returns the contents of one column of a result set The field parameter can be one of three values: the offset, the fieldname, or the field's
table name dot field name The column name will be the alias value if specified If processing several columns or the entire row of the result set, you should use
mssql_fetch_row(), mssql_fetch_array(), or mssql_fetch_object() because they are more efficient Also note that specifying an offset is more efficient than using column names
mssql_select_db()
Syntax
int mssql_select_db (string database_name [, int link_identifier])
Description
The mssql_select_db() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, sets the active database for the server that is referenced by the link_identifier parameter If no link_identifier is specified,
an attempt will be made to open a connection as though mssql_connect() were called
mSQL
The mSQL functions enable you access to data in an mSQL database More information can be found at http://www.Hughes.com.ua To include support for this database, compile with the –-with-msql=[dir] option where dir is typically
/usr/local/Hughes The following example connects to the user database and retrieves user123's password from the users table:
<?
$msql_link_id = msql_connect("users");
Trang 5$msql_result_id =
msql_query ("select password from users where
username=user123",$msql_link_id);
$results = msql_fetch(msql_result_id);
echo $results[0];
mssql_close($msql_link_id);
?>
msql()
Syntax
int msql (string database, string query, int link_identifier)
Description
The msql() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, executes the query against the database specified using the optional link_identifier parameter If no link_identifier is specified, it attempts to
create a connection as though msql_connect() were called with no arguments The return value is an mSQL query identifier to the query result, or FALSE on error
msql_affected_rows()
