inserting multiple tables data in sqlite database - ios

Question

I have created multiple tables in my database. And now I want insert data into those tables. How to insert multiple tables data can anyone help regarding this.
I have written this code for creating 1 table:
NSString *insertSQL = [NSString stringWithFormat: #"INSERT INTO ATRG (id, name, language,imgurl) VALUES ( \"%#\",\"%#\",\"%#\",\"%#\")", ID, name, lang,imgUrl];
const char *insert_stmt = [insertSQL UTF8String]; sqlite3_prepare_v2(_globalDataBase, insert_stmt, -1, &statement, NULL); if (sqlite3_step(statement) == SQLITE_DONE)
{
NSLog(#"Record Inserted");
} else { NSLog(#"Failed to Insert Record");
}

Try this I hope it would be helpful!! This is mine code for insert data
#import "Sqlitedatabase.h"
#implementation Sqlitedatabase
+(NSString* )getDatabasePath
{
NSString *docsDir;
NSArray *dirPaths;
sqlite3 *DB;
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = dirPaths[0];
NSString *databasePath = [docsDir stringByAppendingPathComponent:#"myUser.db"];
NSFileManager *filemgr = [[NSFileManager alloc]init];
if ([filemgr fileExistsAtPath:databasePath]==NO) {
const char *dbpath = [databasePath UTF8String];
if (sqlite3_open(dbpath,&DB)==SQLITE_OK) {
char *errorMessage;
const char *sql_statement = "CREATE TABLE IF NOT EXISTS users(ID INTEGER PRIMARY KEY AUTOINCREMENT,FIRSTNAME TEXT,LASTNAME TEXT,EMAILID TEXT,PASSWORD TEXT,BIRTHDATE DATE)";
if (sqlite3_exec(DB,sql_statement,NULL,NULL,&errorMessage)!=SQLITE_OK) {
NSLog(#"Failed to create the table");
}
sqlite3_close(DB);
}
else{
NSLog(#"Failded to open/create the table");
}
}
NSLog(#"database path=%#",databasePath);
return databasePath;
}
+(NSString*)encodedString:(const unsigned char *)ch
{
NSString *retStr;
if(ch == nil)
retStr = #"";
else
retStr = [NSString stringWithCString:(char*)ch encoding:NSUTF8StringEncoding];
return retStr;
}
+(BOOL)executeScalarQuery:(NSString*)str{
NSLog(#"executeScalarQuery is called =%#",str);
sqlite3_stmt *statement= nil;
sqlite3 *database;
BOOL fRet = NO;
NSString *strPath = [self getDatabasePath];
if (sqlite3_open([strPath UTF8String],&database) == SQLITE_OK) {
if (sqlite3_prepare_v2(database, [str UTF8String], -1, &statement, NULL) == SQLITE_OK) {
if (sqlite3_step(statement) == SQLITE_DONE)
fRet =YES;
}
sqlite3_finalize(statement);
}
sqlite3_close(database);
return fRet;
}
+(NSMutableArray *)executeQuery:(NSString*)str{
sqlite3_stmt *statement= nil; // fetch data from table
sqlite3 *database;
NSString *strPath = [self getDatabasePath];
NSMutableArray *allDataArray = [[NSMutableArray alloc] init];
if (sqlite3_open([strPath UTF8String],&database) == SQLITE_OK) {
if (sqlite3_prepare_v2(database, [str UTF8String], -1, &statement, NULL) == SQLITE_OK) {
while (sqlite3_step(statement) == SQLITE_ROW) {
NSInteger i = 0;
NSInteger iColumnCount = sqlite3_column_count(statement);
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
while (i< iColumnCount) {
NSString *str = [self encodedString:(const unsigned char*)sqlite3_column_text(statement, (int)i)];
NSString *strFieldName = [self encodedString:(const unsigned char*)sqlite3_column_name(statement, (int)i)];
[dict setObject:str forKey:strFieldName];
i++;
}
[allDataArray addObject:dict];
}
}
sqlite3_finalize(statement);
}
sqlite3_close(database);
return allDataArray;
}
#end
And called that method where you want to use!!
NSString *insertSql = [NSString stringWithFormat:#"INSERT INTO users(firstname,lastname,emailid,password,birthdate) VALUES ('%#','%#','%#','%#','%#')",_firstNameTextField.text,_lastNameTextField.text,_emailTextField.text,_passwordTextField.text,_BirthdayTextField.text];
if ([Sqlitedatabase executeScalarQuery:insertSql]==YES)
{
[self showUIalertWithMessage:#"Registration succesfully created"];
}else{
NSLog(#"Data not inserted successfully");
}
And If you want to fetch data from table then you can do this!!
NSString *insertSql = [NSString stringWithFormat:#"select emailid,password from users where emailid ='%#' and password = '%#'",[_usernameTextField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]],[_passwordTextField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]];
NSMutableArray *data =[Sqlitedatabase executeQuery:insertSql];
NSLog(#"Fetch data from database is=%#",data);
Multiple Execute Query!!
NSString *insertSql = [NSString stringWithFormat:#"INSERT INTO users (firstname,lastname,emailid,password,birthdate) VALUES ('%#','%#','%#','%#','%#')",_firstNameTextField.text,_lastNameTextField.text,_emailTextField.text,_passwordTextField.text,_BirthdayTextField.text];
NSString *insertSql1 = [NSString stringWithFormat:#"INSERT INTO contact (firstname,lastname,emailid,password,birthdate) VALUES ('%#','%#','%#','%#','%#')",_firstNameTextField.text,_lastNameTextField.text,_emailTextField.text,_passwordTextField.text,_BirthdayTextField.text];
NSMutableArray * array = [[NSMutableArray alloc]initWithObjects:insertSql,insertSql1,nil];
for (int i=0; i<array.count; i++)
{
[Sqlitedatabase executeScalarQuery:[array objectAtIndex:i]];
}
