(PHP 4, PHP 5, PHP 7, PHP 8)

odbc_fetch_row — Fetch a row

说明

odbc_fetch_row(Odbc\Result $statement, ?int $row = null): bool

Fetches a row of the data that was returned by odbc_do() or odbc_exec(). After odbc_fetch_row() is called, the fields of that row can be accessed with odbc_result().

参数

statement

ODBC 结果对象.

row

If row is not specified, odbc_fetch_row() will try to fetch the next row in the result set. Calls to odbc_fetch_row() with and without row can be mixed.

To step through the result more than once, you can call odbc_fetch_row() with row 1, and then continue doing odbc_fetch_row() without row to review the result. If a driver doesn't support fetching rows by number, the row parameter is ignored.

返回值

Returns true if there was a row, false otherwise.

错误／异常

An E_WARNING is emitted when row is equal or less than zero.
