to solve this problem i need to modify function

below to allow multi threads

so that i need to modify function to allow multi threads

How i do that in code

public static int ExecuteNonQuery(string sql, DbParameter[] dbprmParameters = null)
{
return ExecuteNonQuery(sql, null, dbprmParameters);
}
public static int ExecuteNonQuery(string sql, IDbConnection dbConnection, DbParameter[] @params = null)
{
int RecordsCount = 0;
lock (synObj)
{
if (cmd.CommandTimeout < 360)
cmd.CommandTimeout = 360;
if (sql == "") return 0;
sql = AnalyizeBooleanFields(sql);
cmd.CommandText = sql;
cmd.Parameters.Clear();
if (@params != null)
{
for (int i = 0; i < @params.Length; i++)
{
cmd.Parameters.Add(@params[i]);
}
}
if (dbConnection == null)
{
if (WithTransaction)
dbConnection = BeginTransaction();
else
dbConnection = InitializeConnection();
}
if (dbConnection.State != ConnectionState.Open) dbConnection.Open();
if (WithTransaction) cmd.Transaction = _transaction;
cmd.Connection = dbConnection;
RecordsCount = cmd.ExecuteNonQuery();
if (!WithTransaction) dbConnection.Close();
}
return RecordsCount;
}
1. public static string AnalyizeBooleanFields(string sql)
2. {
3. switch (DataAccess.Provider)
4. {
5. case Providers.Access2003:
6. case Providers.Access2007:
7. sql = sql.Replace("{{1}}", "True");
8. sql = sql.Replace("{{0}}", "False");
9. break;
10. case Providers.SQLServer:
11. case Providers.MySQL:
12. case Providers.Oracle:
13. default:
14. sql = sql.Replace("{{1}}", "1");
15. sql = sql.Replace("{{0}}", "0");
16. break;
17. }
18. return sql;
19. }
21. }
