Closed 6 years ago.
I have used sqlite database in my app.I am doing CURD operation.I get data from json then i convert that data into arrays after that from arrays i insert the data into sqlite database.In my app when data can be upto more than 1000 records.When database is done then i get memory warning.
I have one function for Inserting data.It firstly check if data exists then update data else insert new record
[[DBManager getSharedInstance]insertData:object];
Function definition -
(BOOL) insertData:(SubComponent *)subcomponent
{
const char *dbpath = [databasePath UTF8String];
if([self getSubComponentDataBySubclientClientInspectionid:subcomponent.componentid : subcomponent.componentsubclientid:subcomponent.componentClientid : subcomponent.componentinspectionid] != nil)
{
[self updateCompSubComponentDataBySubclientId:subcomponent];
return YES;
}
else
{
if (sqlite3_open(dbpath, &database) == SQLITE_OK)
{
if (sqlite3_exec(database, [#"PRAGMA CACHE_SIZE=500000;" UTF8String], NULL, NULL, NULL) == SQLITE_OK) {
NSLog(#"Successfully changed cache size");
}
else
NSLog(#"Error: failed to set cache size with message %s.", sqlite3_errmsg(database));
NSLog(#"inside isnert query");
NSString *insertSQL = [NSString stringWithFormat:
#"insert into subcomponent(subcomponentid,name,createddate,subclientid,clientid,cliententityid, inspectionid, initialstatus,componentclientname,componentsubclientname, checkedstatus) values (\"%#\",\"%#\",\"%#\",\"%#\",\"%#\",\"%#\",\"%#\",\"%ld\",\"%#\",\"%#\",\"2\")",subcomponent.componentid,subcomponent.componentName,subcomponent.componentcreateddate,subcomponent.componentsubclientid,subcomponent.componentClientid, subcomponent.componentEntityid,subcomponent.componentinspectionid,(long)subcomponent.componentStatus,subcomponent.componentClientName,subcomponent.componentSubclientName];
NSLog(#"%#",insertSQL);
const char *insert_stmt = [insertSQL UTF8String];
sqlite3_prepare_v2(database, insert_stmt,-1, &statement, NULL);
if (sqlite3_step(statement) == SQLITE_DONE)
{
sqlite3_finalize(statement);
return YES;
}
else
{
NSLog(#"REMASH DB ERROR %s",sqlite3_errmsg(database));
// sqlite3_reset(statement);
//sqlite3_close(database);
sqlite3_finalize(statement);
return NO;
}
}
sqlite3_close(database);
}
return YES;
}

Update Function

{
if(SQLITE_DONE != sqlite3_step(statement))
{
NSLog(#"REMASH Error while updating. '%s'", sqlite3_errmsg(database));
}
else
{
//sqlite3_reset(statement);
NSLog(#"Update done successfully!");
}
}
NSLog(#"NOT OK");
sqlite3_finalize(statement);
sqlite3_close(database);
}
}
PS:Can somebody suggest whether use of sqlite_finilaize(),sqlite_close().sqlite_reset() is correct by seeing my code.Because memory is increasing.

This is not a Database issue.
This issue is caused because Application doesn't have a storyboard for the device you are trying to run upon.
XCode no valid compiled storyboard at path
