fbsql_query - Send a FrontBase query

SYNOPSIS

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

DESCRIPTION

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

	If  the  query	succeeds,  you	can  call  fbsql_num_rows(3)  to  find	out  how  many	rows  were  returned  for  a  SELECT  statement or
       fbsql_affected_rows(3) to find out how many rows were affected by a DELETE, INSERT, REPLACE, or UPDATE statement.

PARAMETERS

	      o $query
		- The SQL query to be executed.

	      Note

		      The query string shall always end with a semicolon.

	      o $
		link_identifier -A FrontBase link identifier returned by fbsql_connect(3) or fbsql_pconnect(3).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(3) was called with no arguments.

	      o $batch_size
		-

RETURN VALUES

       fbsql_query(3) 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(3) returns a new result identifier that you can pass to fbsql_result(3).

       fbsql_query(3) 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(3) fails and returns FALSE:

       Example #1

	      fbsql_query(3) 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(3) fails and returns FALSE:

       Example #2

	      fbsql_query(3) example

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

MAXDB_AFFECTED_ROWS(3)							 1						    MAXDB_AFFECTED_ROWS(3)

maxdb_affected_rows - Gets the number of affected rows in a previous MaxDB operation

       Procedural style

SYNOPSIS

       int maxdb_affected_rows (resource  $link)

DESCRIPTION

       Object oriented style
       int$maxdb->affected_rows ()

       maxdb_affected_rows(3)  returns	the number of rows affected by the last INSERT, UPDATE, or DELETE query associated with the provided $link
       parameter. If this number cannot be determined, this function will return -1.

       Note

	       For SELECT statements maxdb_affected_rows(3) works like maxdb_num_rows(3).

	The maxdb_affected_rows(3) function only works with queries which modify a table. In order to return the number  of  rows  from  a  SELECT
       query, use the maxdb_num_rows(3) function instead.

RETURN VALUES

	An  integer  greater  than  zero  indicates  the number of rows affected or retrieved. Zero indicates that no records where updated for an
       UPDATE statement, no rows matched the WHERE clause in the query or that no query has yet been executed. -1 indicates  that  the	number	of
       rows affected can not be determined.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      maxdb_report (MAXDB_REPORT_OFF);
	      $maxdb->query("DROP TABLE mycustomer");
	      maxdb_report (MAXDB_REPORT_ERROR);

	      /* Insert rows */
	      $maxdb->query("CREATE TABLE mycustomer AS SELECT * from hotel.customer");
	      printf("Affected rows (INSERT): %d
", $maxdb->affected_rows);

	      $maxdb->query("ALTER TABLE mycustomer ADD Status int default 0");

	      /* update rows */
	      $maxdb->query("UPDATE mycustomer SET Status=1 WHERE cno > 50");
	      printf("Affected rows (UPDATE): %d
", $maxdb->affected_rows);

	      /* delete rows */
	      $maxdb->query("DELETE FROM mycustomer WHERE cno < 50");
	      printf("Affected rows (DELETE): %d
", $maxdb->affected_rows);

	      /* select all rows */
	      $result = $maxdb->query("SELECT title FROM mycustomer");
	      printf("Affected rows (SELECT): %d
", $maxdb->affected_rows);

	      $result->close();

	      /* Delete table Language */
	      $maxdb->query("DROP TABLE mycustomer");

	      /* close connection */
	      $maxdb->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

	      if (!$link) {
		 printf("Can't connect to localhost. Error: %s
", maxdb_connect_error());
		 exit();
	      }

	      maxdb_report (MAXDB_REPORT_OFF);
	      maxdb_query($link,"DROP TABLE mycustomer");
	      maxdb_report (MAXDB_REPORT_ERROR);

	      /* Insert rows */
	      maxdb_query($link, "CREATE TABLE mycustomer AS SELECT * from hotel.customer");
	      printf("Affected rows (INSERT): %d
", maxdb_affected_rows($link));

	      maxdb_query($link, "ALTER TABLE mycustomer ADD Status int default 0");

	      /* update rows */
	      maxdb_query($link, "UPDATE mycustomer SET Status=1 WHERE cno > 50");
	      printf("Affected rows (UPDATE): %d
", maxdb_affected_rows($link));

	      /* delete rows */
	      maxdb_query($link, "DELETE FROM mycustomer WHERE cno < 50");
	      printf("Affected rows (DELETE): %d
", maxdb_affected_rows($link));

	      /* select all rows */
	      $result = maxdb_query($link, "SELECT title FROM mycustomer");
	      printf("Affected rows (SELECT): %d
", maxdb_affected_rows($link));

	      maxdb_free_result($result);

	      /* Delete table Language */
	      maxdb_query($link, "DROP TABLE mycustomer");

	      /* close connection */
	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       Affected rows (INSERT): 15
       Affected rows (UPDATE): 15
       Affected rows (DELETE): 0
       Affected rows (SELECT): 15
