												 				  Send a FrontBase query				  				 				 				 fbsql_pconnect				 fbsql_read_blob				 FrontBase Functions				 PHP Manual								 				  fbsql_query				  (PHP 4 >= 4.0.6, PHP 5)fbsql_query — Send a FrontBase query								 				 				 				  Description				  				   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.				  				 												 				  Parameters				  				   								    								     query												     								      				       The SQL query to be executed.				      				      Note: 				       				        The query string shall always end with a semicolon.				       				      				     								    								    								link_identifier												A FrontBase link identifier				returned by fbsql_connect() or 				fbsql_pconnect().If optional and not specified,				the function will try to find an open link to the FrontBase server and if no				such link is found it will try to create one as if 				fbsql_connect() was called with no arguments																    								     batch_size												     								      				      				     								    								   								  				 												 				  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");?>												    								   				  				 												 				  See Also				  				   				    fbsql_affected_rows()				    fbsql_db_query()				    fbsql_free_result()				    fbsql_result()				    fbsql_select_db()				    fbsql_connect()				   				  				 																 fbsql_pconnect				 fbsql_read_blob				 FrontBase Functions				 PHP Manual
