    <p>Is there a way to batch stored procedure calls in MySql with the .Net / Connector to increase performance?</p> <p>Here's the scenario... I'm using a stored procedure that accepts a few parameters as input. This procedure basically checks to see whether an existing record should be updated or a new one inserted (I'm not using INSERT INTO .. ON DUPLICATE KEY UPDATE because the check involves date ranges, so I can't really make a primary key out of the criteria).</p> <p>I want to call this procedure a lot of times (let's say batches of 1000 or so). I can of course, use one MySqlConnection and one MySqlCommand instance and keep changing the parameter values, and calling .ExecuteNonQuery(). </p> <p>I'm wondering if there's a better way to batch these calls?</p> <p>The only thought that comes to mind is to manually construct a string like 'call sp_myprocedure(@parama_1,@paramb_1);call sp_myprocedure(@parama_2,@paramb2);...', and then create all the appropriate parameters. I'm not convinced this will be any better than calling .ExecuteNonQuery() a bunch of times.</p> <p>Any advice? Thanks!</p> <p><strong>EDIT: More info</strong><br> I'm actually trying to store data from an external data source, on a regular basis. Basically I'm taking rss feeds of Domain auctions (from various sources like godaddy, pool, etc.), and updating a table with the auction info using this stored procedure (let's call it sp_storeSale). Now, in this table that the sale info gets stored, I want to keep historical records for sales for a given domain, so I have a <em>domain</em> table, and a <em>sale</em> table. The <em>sale</em> table has a many to one relationship with the <em>domain</em> table. </p> <p>Here's the stored procedure:</p> <pre><code> -- -------------------------------------------------------------------------------- -- Routine DDL -- Note: comments before and after the routine body will not be stored by the server -- -------------------------------------------------------------------------------- DELIMITER $$ CREATE PROCEDURE `DomainFace`.`sp_storeSale` ( middle VARCHAR(63), extension VARCHAR(10), brokerId INT, endDate DATETIME, url VARCHAR(500), category INT, saleType INT, priceOrBid DECIMAL(10, 2), currency VARCHAR(3) ) BEGIN DECLARE existingId BIGINT DEFAULT NULL; DECLARE domainId BIGINT DEFAULT 0; SET @domainId = fn_getDomainId(@middle, @extensions); SET @existingId = ( SELECT id FROM sale WHERE domainId = @domainId AND brokerId = @brokerId AND UTC_TIMESTAMP() BETWEEN startDate AND endDate ); IF @existingId IS NOT NULL THEN UPDATE sale SET endDate = @endDate, url = @url, category = @category, saleType = @saleType, priceOrBid = @priceOrBid, currency = @currency WHERE id = @existingId; ELSE INSERT INTO sale (domainId, brokerId, startDate, endDate, url, category, saleType, priceOrBid, currency) VALUES (@domainId, @brokerId, UTC_TIMESTAMP(), @endDate, @url, @category, @saleType, @priceOrBid, @currency); END IF; END </code></pre> <p>As you can see, I'm basically looking for an existing record that is not 'expired', but has the same domain, and broker, in which case I assume the auction is not over yet, and the data is an update to the existing auction. Otherwise, I assume the auction is over, it is a historical record, and the data I've got is for a new auction, so I create a new record.</p> <p>Hope that clears up what I'm trying to achieve :)</p>

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.
