ifx_prepare - Prepare an SQL-statement for execution

SYNOPSIS

       resource ifx_prepare (string  $query, resource  $link_identifier, [int  $cursor_def], mixed  $blobidarray)

DESCRIPTION

	Prepares a $query for later use with ifx_do(3).

	For "select-type" queries a cursor is declared and opened. Non-select queries are "execute immediate".

	For either query type the number of (estimated or real) affected rows is saved for retrieval by ifx_affected_rows(3).

	If  the contents of the TEXT (or BYTE) column allow it, you can also use ifx_textasvarchar(1) and ifx_byteasvarchar(1). This allows you to
       treat TEXT (or BYTE) columns just as if they were ordinary (but long) VARCHAR columns for select queries, and you don't need to bother with
       blob id's.

	With  ifx_textasvarchar(0)  or ifx_byteasvarchar(0) (the default situation), select queries will return BLOB columns as blob id's (integer
       value). You can get the value of the blob as a string or file with the blob functions (see below).

PARAMETERS

	      o $query
		- The query string.

	      o $link_identifier
		- The link identifier.

	      o $cursor_def
		- This optional parameter allows you to make this a scroll and/or hold cursor. It's  a	bitmask  and  can  be  either  IFX_SCROLL,
		IFX_HOLD, or both or'ed together.

	      o $blobidarray
		-  If  you  have BLOB (BYTE or TEXT) columns in the query, you can add a $blobidarray parameter containing the corresponding "blob
		ids", and you should replace those columns with a "?" in the query text.

RETURN VALUES

	Returns a valid result identifier for use by ifx_do(3), or FALSE on errors.

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");
	      ?>
