    <p>I'm selecting about 20,000 records from the database and then I update them one by one.<br /> I looked for this error and I saw that setting the CommandTimeout will help, but not in my case.<br /></p> <pre><code> public void Initialize() { MySqlConnectionStringBuilder SQLConnect = new MySqlConnectionStringBuilder(); SQLConnect.Server = SQLServer; SQLConnect.UserID = SQLUser; SQLConnect.Password = SQLPassword; SQLConnect.Database = SQLDatabase; SQLConnect.Port = SQLPort; SQLConnection = new MySqlConnection(SQLConnect.ToString()); } public MySqlDataReader SQL_Query(string query) { MySqlCommand sql_command; sql_command = SQLConnection.CreateCommand(); sql_command.CommandTimeout = int.MaxValue; sql_command.CommandText = query; MySqlDataReader query_result = sql_command.ExecuteReader(); return query_result; } public void SQL_NonQuery(string query) { MySqlCommand sql_command; sql_command = SQLConnection.CreateCommand(); sql_command.CommandTimeout = int.MaxValue; sql_command.CommandText = query; sql_command.ExecuteNonQuery(); } </code></pre> <p>And here is my method which makes the select query:</p> <pre><code> public void CleanRecords() { SQLActions.Initialize(); SQLActions.SQL_Open(); MySqlDataReader cashData = SQLActions.SQL_Query("SELECT `cash`.`id`, SUM(`cash`.`income_money`) AS `income_money`, `cash_data`.`total` FROM `cash_data` JOIN `cash` ON `cash`.`cash_data_id` = `cash_data`.`id` WHERE `user`='0' AND `cash_data`.`paymentterm_id`='0' OR `cash_data`.`paymentterm_id`='1' GROUP BY `cash_data_id`"); while(cashData.Read()){ if(cashData["income_money"].ToString() == cashData["total"].ToString()){ UpdateRecords(cashData["id"].ToString()); } } SQLActions.SQL_Close(); } </code></pre> <p>And here is the method which makes the update:</p> <pre><code> public void UpdateRecords(string rowID) { SQLActions.Initialize(); SQLActions.SQL_Open(); SQLActions.SQL_NonQuery("UPDATE `cash_data` SET `end_date`='" + GetMeDate() + "', `user`='1' WHERE `id`='" + rowID + "'"); SQLActions.SQL_Close(); } </code></pre> <p>Changing the database structure is not an option for me.<br /> I thought that setting the timeout to the maxvalue of int will solve my problem, but is looks like this wont work in my case. Any ideas? :)</p> <p>EDIT: The error which I get is "Fatal error encoutered during data read".</p> <p><br /><br /><br /><br /></p> <p>UPDATE:</p> <pre><code> public void CleanRecords() { StringBuilder dataForUpdate = new StringBuilder(); string delimiter = ""; SQLActions.Initialize(); SQLActions.SQL_Open(); MySqlDataReader cashData = SQLActions.SQL_Query("SELECT `cash`.`id`, SUM(`cash`.`income_money`) AS `income_money`, `cash_data`.`total` FROM `cash_data` JOIN `cash` ON `cash`.`cash_data_id` = `cash_data`.`id` WHERE `user`='0' AND `cash_data`.`paymentterm_id`='0' OR `cash_data`.`paymentterm_id`='1' GROUP BY `cash_data_id`"); while (cashData.Read()) { if (cashData["income_money"].ToString() == cashData["total"].ToString()) { dataForUpdate.Append(delimiter); dataForUpdate.Append("'" + cashData["id"].ToString() + "'"); delimiter = ","; } } SQLActions.SQL_Close(); UpdateRecords(dataForUpdate.ToString()); } public void UpdateRecords(string rowID) { SQLActions.Initialize(); SQLActions.SQL_Open(); SQLActions.SQL_NonQuery("UPDATE `cash_data` SET `end_date`='" + GetMeDate() + "', `user`='1' WHERE `id` IN (" + rowID + ")"); SQLActions.SQL_Close(); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
