PHP Developer’s Dictionary IT-SC book 425 int 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. mssql_free_result() Syntax int mssql_free_result (int result) 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. mssql_get_last_message Syntax string msssql_get_last_message (void) PHP Developer’s Dictionary IT-SC book 426 Description 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 PHP Developer’s Dictionary IT-SC book 427 The 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 link_identifier parameter. If no link_identifier is specified, a connection PHP Developer’s Dictionary IT-SC book 428 attempt 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"); PHP Developer’s Dictionary IT-SC book 429 $msql_result_id = msql_query ("select password from users where username=user123",$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() Syntax int msql_affected_rows (int query_identifier) Description The msql_affected_rows() function, which is available from PHP 3.0.6 to PHP 3.0.16 along with PHP 4.0 and higher, returns the number of rows impacted by the execution of the query referenced by the query_identifier parameter. msql_close() Syntax int msql_close (int link identifier) . msssql_get_last_message (void) PHP Developer’s Dictionary IT-SC book 426 Description 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,. (int result) Description PHP Developer’s Dictionary IT-SC book 427 The mssql_num_fields() function, which is available from PHP 3.0 to PHP 3.0.16 along with PHP 4.0 and higher, returns. 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 link_identifier parameter. If no link_identifier is specified, a connection PHP Developer’s
