fbsql_querySend a FrontBase query


resource fbsql_query ( string $query [, resource $link_identifier [, int $batch_size ]] )

Sends a query to the currently active database on the server.

If the query succeeds, you can call fbsql_num_rows() to find out how many rows were returned for a SELECT statement or fbsql_affected_rows() to find out how many rows were affected by a DELETE, INSERT, REPLACE, or UPDATE statement.



The SQL query to be executed.


The query string shall always end with a semicolon.


fbsql_connect()fbsql_pconnect()가 반환한 FrontBase 연결 식별자.

선택적이고 지정하지 않았을 때, 함수는 FrontBase 서버로 열려있는 연결을 찾고, 찾지 못하면 fbsql_connect()를 인수 없이 호출했을 때처럼 연결을 시도합니다.



fbsql_query() returns TRUE (non-zero) or FALSE to indicate whether or not the query succeeded. A return value of TRUE means that the query was legal and could be executed by the server. It does not indicate anything about the number of rows affected or returned. It is perfectly possible for a query to succeed but affect no rows or return no rows.

For SELECT statements, fbsql_query() returns a new result identifier that you can pass to fbsql_result().

fbsql_query() will also fail and return FALSE if you don't have permission to access the table(s) referenced by the query.


The following query is syntactically invalid, so fbsql_query() fails and returns FALSE:

Example #1 fbsql_query() example

fbsql_query("SELECT * WHERE 1=1")
    or die (
"Invalid query");

The following query is semantically invalid if my_col is not a column in the table my_tbl, so fbsql_query() fails and returns FALSE:

Example #2 fbsql_query() example

fbsql_query ("SELECT my_col FROM my_tbl;")
    or die (
"Invalid query");
