fbsql_result
(PHP 4 >= 4.0.6, PHP 5, PHP 7)
fbsql_result — Get result data
说明
Returns the contents of one cell from a FrontBase
result set.
When working on large result sets, you should consider using one of the functions that fetch an entire row (specified below). As these functions return the contents of multiple cells in one function call, they're MUCH quicker than fbsql_result().
Calls to fbsql_result() should not be mixed with calls to other functions that deal with the result set.
参数
-
result -
由 fbsql_query() 或 fbsql_db_query() 返回的结果标识符。
-
row -
-
field -
Can be the field's offset, or the field's name, or the field's table dot field's name (tablename.fieldname).
If the column name has been aliased ('select foo as bar from...'), use the alias instead of the column name.
Note:
Specifying a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.
