(PHP 5, PHP 7 < 7.4.0)
ibase_query — Execute a query on an InterBase database
说明
ibase_query
([ resource $link_identifier
], string $query
[, int $bind_args
] ) : resource
Performs a query on an InterBase database.
参数
link_identifier- An InterBase link identifier. If omitted, the last opened link is assumed.
query- An InterBase query.
bind_args
返回值
If the query raises an error, returns false. If it is successful and
there is a (possibly empty) result set (such as with a SELECT query),
returns a result identifier. If the query was successful and there were
no results, returns true.
Note:
In PHP 5.0.0 and up, this function will return the number of rows affected by the query for INSERT, UPDATE and DELETE statements. In order to retain backward compatibility, it will return
truefor these statements if the query succeeded without affecting any rows.
错误／异常
If you get some error like "arithmetic exception, numeric overflow, or string truncation. Cannot transliterate character between character sets" (this occurs when you try use some character with accents) when using this and after ibase_query() you must set the character set (i.e. ISO8859_1 or your current character set).
