Notice
1: The columns of the incoming DataTable must be consistent with the table columns in the database, otherwise the data will be stored in the first few columns by default.
2: As long as the sql statement is a query to the table to be inserted, the purpose is to determine the table name
3: The method to obtain the connection string is GetOracleConnection(), you need to add it yourself
public static bool insertValueWithDt(DataTable dataTable, string sql)
{
String ConnStr = GetOracleConnection();
using (OracleConnection conn = new OracleConnection(ConnStr))
{
try
{
OracleCommand cmd = new OracleCommand(sql,conn);
OracleDataAdapter adapter = new OracleDataAdapter(cmd);
OracleCommandBuilder cb = new OracleCommandBuilder(adapter);
DataTable dsNew = new DataTable();
int count = adapter.Fill(dsNew);
for (int i = 0; i < dataTable.Rows.Count; i++)
{
DataRow dr = dsNew.NewRow();
for (int j = 0; j < dataTable.Columns.Count; j++)
{
dr[dsNew.Columns[j].ColumnName] = dataTable.Rows[i][j];
}
dsNew.Rows.Add(dr);
}
count = adapter.Update(dsNew);
adapter.UpdateBatchSize = 200;
//adapter.Update(dataTable);
return true;
}
catch (Exception e)
{
WriteLog writeLog = new WriteLog();
writeLog.WriteLogs(e.ToString());
return false;
}
}
}
