[sqlite] inserting blob data
Hi, I'm using 3.2.2. I have a binary data in a variable which I want to store as a blob in my database table. I have defined a blob field in my table. Since this binary data varies in size every time, hence I want to store it as blob. Please let me know how can I insert a blob data using the function - sqlite_exec_printf(). I also want to later read that data using sqlite_get_table_printf(). Can anybody give an example. Thanks in advance.

[sqlite] Table problem
Hi,
I've choosen sqlite 3.6.11 for a small purpose in my organisation.
The software runs on a proprietroy OS.
SQLite is used by a single process, there are no other threads using SQLite,
hence SQLITE_THREADSAFE = 0.
I have written the memory and OS functions.
My Schema table is very simple, as under.
static char NVDataTable[] =
"CREATE TABLE NVDataTable( "
"iDataId INTEGER PRIMARY KEY, "
"iVoidData INTEGER, "
"iDefaultData INTEGER,"
"cStringId VARCHAR(32) DEFAULT '' NOT NULL,"
"iSize INTEGER, "
"iReadOnly INTEGER, "
"iCiphered INTEGER )";
I was able to successfully Open database - using sqlite3_open().
I was able to successfully create table - using sqlite3_exec().
Ofcourse, I struggled a LOT to achive the above two ... (even though i had
worked on 3.2.2 long ago)
I'm NOT able to INSERT a record into the database using - sqlite3_mprintf() and
sqlite3_exec()
*z = sqlite3_mprintf("INSERT INTO NVDataTable VALUES(NULL, '%d', '%d', \"%s\",
'%d', '%d', '%d' )",
iVoidData, iDefaultData, stTmp, 1u, iReadOnly,
iCiphered);
I get a return error as - 1
And, an error message as - [Error:= no such table: NVDataTable ]
I'm not getting any clue. How do I verify the table after I've created the
table.
I just need to achive INSERT and SELECT.
The SELECT is just a simple fetch of record based on id, there are no complex
or conditional queries.
Please help me.
Thanks in advance.
Mayura S.

[sqlite] compilation : undefined symbols.
Hello Sir, I downloaded sqlite 3.6.11 code for my project in my organisation. I'm not using the amalgamation code. I'm building the source code files in unix environment. I'm not new to sqlite, I have earlier worked on 3.2.2. My project need is very simple - to store and read data (persistent data ). Hence there are no complex/conditional queries or sorting of any kind. I'm building the code with following switches, hence scaling down Sqlite as much as possible to cater only store and read data. -DSQLITE_OS_OTHER=1 -DSQLITE_THREADSAFE=0 -DSQLITE_TEMP_STORE=3 -DSQLITE_OMIT_AUTHORIZATION -DSQLITE_OMIT_AUTOINIT -DSQLITE_OMIT_BETWEEN_OPTIMIZATION -DSQLITE_OMIT_BLOB_LITERAL -DSQLITE_OMIT_BUILTIN_TEST -DSQLITE_OMIT_CHECK -DSQLITE_OMIT_COMPLETE -DSQLITE_OMIT_DATETIME_FUNCS -DSQLITE_OMIT_DECLTYPE -DSQLITE_OMIT_DEPRECATED -DSQLITE_OMIT_FLAG_PRAGMAS -DSQLITE_OMIT_FLOATING_POINT -DSQLITE_OMIT_GET_TABLE -DSQLITE_OMIT_INCRBLOB -DSQLITE_OMIT_INTEGRITY_CHECK -DSQLITE_OMIT_LIKE_OPTIMIZATION -DSQLITE_OMIT_LOAD_EXTENSION -DSQLITE_OMIT_LOCALTIME -DSQLITE_OMIT_PAGER_PRAGMAS -DSQLITE_OMIT_PROGRESS_CALLBACK -DSQLITE_OMIT_SCHEMA_PRAGMAS -DSQLITE_OMIT_SCHEMA_VERSION_PRAGMAS -DSQLITE_OMIT_SHARED_CACHE -DSQLITE_OMIT_SUBQUERY -DSQLITE_OMIT_TCL_VARIABLE -DSQLITE_OMIT_TRACE -DSQLITE_OMIT_TRUNCATE_OPTIMIZATION -DSQLITE_OMIT_UTF16 -DSQLITE_OMIT_XFER_OPT -DSQLITE_OMIT_ALTERTABLE -DSQLITE_OMIT_ANALYZE -DSQLITE_OMIT_ATTACH -DSQLITE_OMIT_AUTOINCREMENT -DSQLITE_OMIT_AUTOVACUUM -DSQLITE_OMIT_CAST -DSQLITE_OMIT_COMPOUND_SELECT -DSQLITE_OMIT_CONFLICT_CLAUSE -DSQLITE_OMIT_EXPLAIN -DSQLITE_OMIT_FOREIGN_KEY -DSQLITE_OMIT_PRAGMA -DSQLITE_OMIT_REINDEX -DSQLITE_OMIT_TEMPDB -DSQLITE_OMIT_VACUUM -DSQLITE_OMIT_VIEW -DSQLITE_OMIT_VIRTUALTABLE -DSQLITE_SYSTEM_MALLOC ... but I'm getting the following symbols as Undefined.

Error: L6218E: Undefined symbol sqlite3VtabArgExtend (referred from sqlite.ptl) The above symbols are not available in the '#else' code of any compiler switch. Most of the compiler switch do not have any '#else' code. Please guide me on resolving these symbols. All the above symbols are used in parse.c file. I believe parse.c is a generated file. Should I make changes in parse.c file ? OR Should I stub those symbols in '#else' code ? Thanks in advance.
