POCreating a Stored Procedure in MySQL with C#

Body
copied!<p>I'm trying to create a new stored procedure programatically using the following code:</p> <pre><code>using (MySqlConnection conn = new MySqlConnection(connectionString)) { conn.Open(); using (MySqlTransaction trans = conn.BeginTransaction()) { using (MySqlCommand command = conn.CreateCommand()) { command.CommandText = query; command.ExecuteNonQuery(); } trans.Commit(); } } </code></pre> <p>And the following text as the create statement copied from Mysql workbench:</p> <pre><code>static string query = @" delimiter $$ CREATE PROCEDURE `GetParentIds`(IN `tempTableName` VARCHAR(255), IN `id` int) BEGIN DECLARE parId INT; DECLARE curId INT; DROP TEMPORARY TABLE IF EXISTS tempTableName; CREATE TEMPORARY TABLE tempTableName ( node_id INT NOT NULL PRIMARY KEY ); set curId := id; get_parents_loop: LOOP set parId := null; set parId = (select ParentID from {TableName} where ID = curId); IF parId is NULL THEN LEAVE get_parents_loop; END IF; INSERT INTO tempTableName(node_id) Values (parId); set curId := parId; END LOOP get_parents_loop; SELECT * FROM tempTableName; END$$"; </code></pre> <p>This procedure is passed an ID of an object which has a parentID and it gets all of the parentIDs of all the parents of the given object and returns them. The problem comes when I try to run it and I get the following message: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'delimiter $$</p> <p>CREATE PROCEDURE <code>GetParentIds</code>(IN <code>tempTableName</code> VARCHAR(255),' at line 1"</p> <p>Any and all Ideas are welcome!</p> <p><strong>* EDIT **</strong> Thanks to all the answers below, this is what finally worked:</p> <pre><code>CREATE PROCEDURE GetParentIds(IN tempTableName VARCHAR(255), IN id int) BEGIN DECLARE parId INT; DECLARE curId INT; DROP TEMPORARY TABLE IF EXISTS tempTableName; CREATE TEMPORARY TABLE tempTableName (node_id INT NOT NULL PRIMARY KEY ); set curId := id; get_parents_loop: LOOP set parId := null; set parId = (select ParentID from TDOs where TDOID = curId); IF parId is NULL THEN LEAVE get_parents_loop; END IF; INSERT INTO tempTableName(node_id) Values (parId); set curId := parId; END LOOP get_parents_loop; SELECT * FROM tempTableName; END; </code></pre>
