$sql_host = ".\SQLEXPRESS";//Ur instance name, E.G: 7\SQLEXPRESS.
$sql_user = "sa";//Your username of SQL, default : sa.
$sql_pass = ""; // Password of SA.
$sql_db = "SRO_VT_ACCOUNT";//Your DB name of ACC, Default:SRO_VT_ACCOUNT
Note : Dont change the whole syntax. , just change the text between " and "
E.G :
"SRO_VT_ACCOUNT"
"sa"
"test"
"7\SQLEXPRESS"
