Encapsulated TSQL Generic Update method in MVC LINQ

Take the TSQL out, do a package, apply all the tables, update there are two kinds, normal update and Count update

Look at the code: These two methods are written in the DAL in the data manipulation base class, only its subclasses can use it, so use protected as the limit

<summary>
Generic Update method
</summary>
<param name= "tableName" > table name </param>
<param name= "param" > Parameter list, odd for field, even for his previous odd number corresponding to the value, index 0 for the primary key to be updated, 1 primary key value </param>
protected virtual void Update (string tableName, params object[] param)
{
StringBuilder sbsql = new StringBuilder ();
list<object> listparasm = new list<object> ();
Listparasm.add (Param[0]);
Listparasm.add (param[1]);
int index = Listparasm.count;
Sbsql.appendformat ("UPDATE [{0}] SET", tableName);

if (index = = 0)
{
Return
}
Else
{
for (int i = 2; i < param. Count (); i + = 2)
{
if (Param[index + 1]. GetType () = = typeof (String))
Sbsql.appendformat ("{{{0}}} = ' {{1}} ',", index, index + 1);
Else
Sbsql.appendformat ("{{{0}}} = {{1}},", index, index + 1);
Listparasm.add (Param[index]);
Listparasm.add (Param[index + 1]);
index++;
index++;
}

Sbsql.remove (sbsql.length-1, 1);//Remove the last comma
}

Sbsql.append ("WHERE [{0}] = {1}");
Db. ExecuteCommand (Sbsql.tostring (), Listparasm.toarray ());
}

<summary>
Count Update
</summary>
<param name= "tableName" > table name </param>
<param name= "param" > Parameter list, index 0 primary Key name, 1 table key value, 2 for the field to be counted, 3 for increment </param>
protected virtual void Updateforcount (string tableName, params object[] param)
{
String sql = "Update [{0}] set [{3}]=[{3}]+{4} where [{1}]={2}";
list<object> listparasm = new list<object>
{
TableName,
Param[0],
PARAM[1],
PARAM[2],
PARAM[3],
};
Db. ExecuteCommand (String. Format (SQL, Listparasm.toarray ()));
}
