根据不同的ID更新ID对应条的Code,Name,Value,Type：
string updateSqlString = " update serverconfigdata set ";
string updateSqlCode = " Code = CASE ID ";
string updateSqlName = " Name = CASE ID ";
string updateSqlValue = " Value = CASE ID ";
string updateSqlType = " Type = CASE ID ";
foreach (ServerConfigData sc in scList)
{
if(!string.IsNullOrEmpty(sc.ID))
{
//updateSqlString = $" update tablename set Code = \'{sc.Code}\',Name = \'{sc.Name}\',Value = \'{sc.Value}\',Type = \'{sc.Type}\' where Code = \'{sc.Code}\'; ";
//DataTable updatedt = mySQLConn.ExecuteDataTable(updateSqlString);
updateSqlCode += $" When {sc.ID} Then \'{sc.Code}\' ";
updateSqlName += $" When {sc.ID} Then \'{sc.Name}\' ";
updateSqlValue += $" When {sc.ID} Then \'{sc.Value}\' ";
updateSqlType += $" When {sc.ID} Then \'{sc.Type}\' ";
updateIDS += $"{sc.ID},";
}
else
{
insertSqlDatas += $" (\'{sc.Code}\',\'{sc.Name}\',\'{sc.Value}\',\'{sc.Type}\'),";
}
}
updateSqlCode += " END ";
updateSqlName += " END ";
updateSqlValue += " END ";
updateSqlType += " END ";
