Hi joe, Thanks for your response.
In order to reduce the footprint size, I have bypassed parser completely and using byte codes directly as my schema and queries are almost compile time fixed. Hence I am not using sqlite3_prepare(). The following is the schema and inserts I am using. CREATE TABLE OBJECT( PUOI INTEGER PRIMARY KEY, Storage_Id INTEGER, Object_Format INTEGER, Protection_Status INTEGER, Object_Size INTEGER, Parent_Object INTEGER, Non_Consumable INTEGER, Object_file_name TEXT, Name TEXT, File_Path TEXT ); CREATE TABLE AUDIO( PUOI INTEGER PRIMARY KEY, Use_Count INTEGER, Audio_Bit_Rate INTEGER, Sample_Rate INTEGER, Audio_Codec_Type INTEGER, Number_of_Channels INTEGER, Track INTEGER, Artist TEXT, Title TEXT, Genre TEXT, Album_Name TEXT, File_Path TEXT ); INSERT INTO OBJECT VALUES ( 7, 65537, 12297, 0, 475805, 6, 0, 'ANJANEYASTOTRAM.mp3', NULL, 'C:\\MTPSim\\Store0\\Music\\Artist\\Album\\ANJANEYASTOTRAM.mp3' ); INSERT INTO AUDIO VALUES ( 7, 6, 144100, 0, 0, 0, 6, NULL, NULL, NULL, NULL, 'C:\\MTPSim\\Store0\\Music\\Artist\\Album\\ANJANEYASTOTRAM.mp3' ); INSERT INTO OBJECT VALUES ( 8, 65537, 12297, 0, 387406, 6, 0, 'BHADRAM.mp3', NULL, 'C:\\MTPSim\\Store0\\Music\\Artist\\Album\\BHADRAM.mp3' ); INSERT INTO AUDIO VALUES ( 8, 6, 144100, 0, 0, 0, 6, NULL, NULL, NULL, NULL, 'C:\\MTPSim\\Store0\\Music\\Artist\\Album\\BHADRAM.mp3' ); Warm regards Kalyani -----Original Message----- From: Joe Wilson [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 29, 2007 9:42 AM To: sqlite-users@sqlite.org Subject: Re: [sqlite] How to restrict the peak heap usage during multiple inserts and updates? > I am working at porting sqlite ( ver 3.3.8 ) on an embedded device with > extremely low main memory. > > I tried running select queries on the tables( with about 2k records each > having about 5 strings) and they do well within 20kB of runtime heap > usage. > > But, when I try new insertions, the heap usage grows tremendously (about > 70 kB at peak). Perhaps preparing the statements (sqlite3_prepare) might decrease RAM use somewhat. Can you post an example of your schema and these insert statements? ________________________________________________________________________ ____________Choose the right car based on your needs.
