fbsql_query

Description

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.

Parameters

Return Values

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.

Examples

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

Example 1. fbsql_query() example <?php $result = 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 <?php $result = fbsql_query ("SELECT my_col FROM my_tbl;")     or die ("Invalid query"); ?>
