    text
    copied!<p>After visiting dozens of websites containing info about SQLite I still cannot find a solution to fix an error while binding a blob. Here is the table decleration:</p> <pre><code>CREATE TABLE ONE ( ID INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, NAME CHAR( 50 ) NOT NULL, LABEL CHAR( 50 ), GRP CHAR( 50 ), FILE BLOB ); </code></pre> <p>And here is the code for insertion:</p> <pre><code>int InsertFile(string name) { const char* dbname = name.c_str(); sqlite3 *database; int rc = sqlite3_open(dbname, &amp;database); char *zErrMsg = 0; unsigned char *buffer = (unsigned char*) malloc(sizeof(char)*MAX); ifstream file; file.open("Sql.pdf", ios::in|ios::binary); if ( ! file ) { cout &lt;&lt; "An error occurred opening the file" &lt;&lt; endl; } int count = 0; const void* fileptr = NULL; fileptr = buffer; while(file.good()) { char c=file.get(); buffer[count]=c; count++; } file.close(); sqlite3_stmt *stmt = NULL; char* statement = "INSERT INTO ONE( ID, NAME, LABEL, GRP, FILE ) VALUES ( NULL, 'fedfsdfss', NULL, NULL, ?);"; rc = sqlite3_prepare_v2(database, statement, 0, &amp;stmt, NULL); rc = sqlite3_bind_blob(stmt, 1, fileptr, sizeof(char)*count, SQLITE_TRANSIENT); const char* result = sqlite3_errmsg(database); rc = sqlite3_step(stmt); result = sqlite3_errmsg(database); sqlite3_close(database); free(buffer); fileptr=NULL; return 0; </code></pre> <p>} EDIT: Pasted full function, the amount of characters im trying to insert is about 350K.</p> <p>The result from binb_blob is always 21, error code contains nothing. buffer contains binary file data, which most probably isn't too big hence the error code. Any hints would be apprieciated. </p>
