SQLite: DB error, "out of memory"
I am using FMDB to create and add a record to a d/b. The method to create the d/b is:
//----------------------- checkIfDatabaseExists -----------------|
+ (void) openCreateDB {
NSArray *searchPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); // Get the path to the database file
NSString *documentPath = [searchPaths objectAtIndex:0];
NSString *databasePath = [documentPath stringByAppendingPathComponent:@"ppcipher.s3db"];
NSLog(@"d/b path: /%@", databasePath);
char * errmsg = nil;
NSFileManager *fileManager = [NSFileManager defaultManager];
[fileManager removeItemAtPath:databasePath error:NULL]; // <------------ delete d/b TESTING ONLY!
BOOL fileExists = [fileManager fileExistsAtPath:databasePath];
if(!fileExists) {
FMDatabase* _db = [FMDatabase databaseWithPath: databasePath];
if (![_db ope开发者_如何学JAVAn]) {
NSLog(@"Could not open/create database");
}
[_db executeUpdate:@"CREATE TABLE CardData (card_id TEXT PRIMARY KEY NOT NULL, card_name TEXT NOT NULL, "
@"card_type TEXT, code_val TEXT, create_date TEXT DEFAULT CURRENT_DATE, user_notes TEXT, gps_loc TEXT)"];
if(errmsg != nil)
NSLog(@"error: %s", errmsg); // DEBUGGING ONLY! (REMOVE when done!)
}
return;
}
Which causes NO errors. However, when I next do one (1) "insert" after the "open", I get an error from FMDB saying DB Error: 7 "out of memory". And every sql statement after this, I get the same error (only the creation of the d/b gave no errors!). Here is the code for the insert:
//--------------------- addRecordToDatabase ----------------------|
+ (void)addRecordToDatabase: (ZBarSymbol *)symbol {
FMDatabase* _db = [FMDatabase sharedFMDatabase];
[_db setLogsErrors:1]; // log all of the SQLite d/b errors
[_db executeUpdate: @"INSERT INTO CardData (card_id, card_name, code_val) VALUES (?, ?, ?)", symbol.data, @"Test Card", symbol.typeName, nil];
}
This is a very small d/b with minimal data. I ran Inspector and nothing was out of the ordinary. Any suggestions would be greatly appreciated.
I think you should just call[_db open]
in your code, that should fix it. It seems that the "out of memory error" in FMDB means also error caused by missing table(s) or connection not open.
