I am attempting to make my saving code more efficient through the use of re-using the prepared statement, the use of transactions, and parametrized queries. However whenever I run the save code only one record ends up in my table. I think it has to do with where the sqlite3_step is placed.
But I also want some other eyes to look over my code and let me know if I am doing things correctly; I could not find an example doing this anywhere so it is a jumble of about six forums posts and Stack Overflow topics I found on the various subjects:
//Planet Data
//Delete previous save data
dData("Generated_Planets", bErrors);
if (plData.size() > 0)
{
sqlite3_exec(dBase, "BEGIN TRANSACTION", NULL, NULL, &error);
sqlStr = "Insert Into Generated_Planets (ID, Name, Affiliation, Disposition, Race, Player_Owned, Is_Destroyed, EKS, Planet_Size, Current_Pop, Max_Pop) Values (?,?,?,?,?,?,?,?,?,?,?);";
if (sqlite3_prepare_v2(dBase, sqlStr.c_str(), sqlStr.size(), &statement, 0) == SQLITE_OK)
{
cout << "Saving planet data";
//Save new data
for (i = 0; i <= plData.size(); i++)
{
if (i == plData.size())
{
finalize(statement, bErrors);
}
else
{
sqlI1 = plData.at(i).pID;
sqlS1 = plData.at(i).pName;
sqlS2 = plData.at(i).pAffiliation;
sqlS3 = plData.at(i).pDispo;
sqlS4 = plData.at(i).pRace;
sqlI2 = plData.at(i).bIsPOwned;
sqlI3 = plData.at(i).bIsDestroyed;
sqlF1 = plData.at(i).pEKS;
sqlF2 = plData.at(i).pSize;
sqlLLI1 = plData.at(i).pCPop;
sqlLLI2 = plData.at(i).pMPop;
find = "'";
temp = "\"";
foundAt = sqlS1.find(find);
if (foundAt != string::npos)
{
sqlS1.replace(foundAt,1,temp);
}
//Bind parameters
sqlite3_bind_int(statement,1,sqlI1);
sqlite3_bind_text(statement,2,sqlS1.c_str(),sqlS1.size(),SQLITE_TRANSIENT);
sqlite3_bind_text(statement,3,sqlS2.c_str(),sqlS2.size(),SQLITE_TRANSIENT);
sqlite3_bind_text(statement,4,sqlS3.c_str(),sqlS3.size(),SQLITE_TRANSIENT);
sqlite3_bind_text(statement,5,sqlS4.c_str(),sqlS4.size(),SQLITE_TRANSIENT);
sqlite3_bind_int(statement,6,sqlI2);
sqlite3_bind_int(statement,7,sqlI3);
sqlite3_bind_double(statement,8,sqlF1);
sqlite3_bind_double(statement,9,sqlF2);
sqlite3_bind_int64(statement,10,sqlLLI1);
sqlite3_bind_int64(statement,11,sqlLLI2);
sqlite3_step(statement);
cout << ".";
}
}
}
else
{
*bErrors = true;
createBInfo();
d.createBReport("SQL Code 2",sqlite3_errmsg(dBase),bLocale + to_string(__LINE__),bTDate,"./SC_Log.txt");
}
sqlite3_exec(dBase, "END TRANSACTION", NULL, NULL, &error);
sFlags_Temp.push_back(saveFlag());
sFlags_Temp.at(sFlags_Temp.size()-1).sfName = "GPlanets";
sFlags_Temp.at(sFlags_Temp.size()-1).sfValue = 1;
cout << "Done" << endl << endl;
