qt讀取資料庫資料並驗證 Qt對sql資料庫的訪問

odbc連線

適合資料庫型別連線方式

access "driver=;dbq=*.mdb;uid=admin;pwd=pass;"

dbase "driver=;driverid=277;dbq=------------;"

oracle "driver=;server=oraclesever.world;uid=admin;pwd=pass;"

mssql server "driver=;server=servername;database=dbname;uid=sa;pwd=pass;"

ms text "driver=;dbq=-----;extensions=asc,csv,tab,txt;persist securityinfo=false;"

visual foxpro "driver=;sourcetype=dbc;sourcedb=*.dbc;exclusive=no;"

mysql "driver=;database=yourdatabase;uid=username;pwd=yourpassword;option=16386;"

sqlite "driver=;database=d:\sqlite\*.db"

postgresql "driver=;server=127.0.0.1;uid=admin;pwd=pass;database=databasename"

oledb連線

適合的資料庫型別連線方式

access "provider=microsoft.jet.oledb.4.0;data source=your_database_path;user id=admin;password=pass;"

oracle "provider=oraoledb.oracle;data source=dbname;user id=admin;password=pass;"

ms sql server "provider=sqloledb;data source=machinename;initial catalog=dbname;userid=sa;password=pass;"

ms text "provider=microsof.jet.oledb.4.0;data source=your_path;extended properties'text;fmt=delimited'"

2、寫入資料庫

3、將sql匯入到access中

1)、從sql中讀取資料

qsqlquery query;

qstringlist m_imei;

qstringlist m_barcode;

qstringlist m_updata_data;

if (rec==tr("全部匯出"))

query.exec("select * from test");

else

query.exec("select * from test where (last_update_date > '"+num1+"') and (last_update_date <='"+num2+"')");

while (query.next())

2)、將讀出的資料寫入到access中

qsqlquery query;

for (int i=0;i

query.value(1)=m_imei.at(i);

query.value(2)=m_barcode.at(i);

query.value(3)=m_uptate_date.at(i);

query.exec("insert into exp(last_update_date,imei,barcode)" "values('"+m_uptate_date.at(i)+"','"+m_imei.at(i)+"','"+m_barcode.at(i)+"')");
