How to execute *.sql mysql file in my c# application

Question

I have a mysql script in a file that I need to be able to execute from my c# application. Here is a sample of what the script contains:

USE osae;

-- Set DB         


        

Answer 1

Take a look here. You should specify a delimiter for MySqlScript (since you have stored procedure in there). And your query should look like:

-- Set DB version 
CALL osae_sp_object_property_set('SYSTEM', 'DB Version', '0.3.5', '', '')$$
CALL osae_sp_object_property_set('SYSTEM', 'Debug', 'FALSE', '', '')$$
CALL osae_sp_object_type_property_add ('Prune Logs','Boolean','TRUE','SYSTEM',0)$$
CALL osae_sp_object_property_set ('SYSTEM','Prune Logs','TRUE','','')$$



DROP PROCEDURE IF EXISTS osae_sp_object_event_script_update$$
CREATE DEFINER = 'root'@'localhost'
PROCEDURE osae_sp_object_event_script_update(IN pobject varchar(200), IN pevent varchar(200), IN ptext text)
BEGIN
DECLARE vObjectCount INT;
DECLARE vObjectID INT;
DECLARE vObjectTypeID INT;
DECLARE vEventCount INT;
DECLARE vEventID INT;
    SELECT COUNT(object_id) INTO vObjectCount FROM osae_object WHERE UPPER(object_name)=UPPER(pobject);
    IF vObjectCount > 0 THEN
              SELECT object_id,object_type_id INTO vObjectID,vObjectTypeID FROM osae_object WHERE UPPER(object_name)=UPPER(pobject);
        SELECT COUNT(event_id) INTO vEventCount FROM osae_object_type_event WHERE object_type_id=vObjectTypeID AND (UPPER(event_name)=UPPER(pevent) OR UPPER(event_label)=UPPER(pevent));
        IF vEventCount = 1 THEN     
            SELECT event_id INTO vEventID FROM osae_object_type_event WHERE object_type_id=vObjectTypeID AND (UPPER(event_name)=UPPER(pevent) OR UPPER(event_label)=UPPER(pevent));
            UPDATE osae_object_event_script SET event_script=ptext WHERE object_id=vObjectID AND event_id=vEventID;
         -- CALL osae_sp_debug_log_add(CONCAT('Updated ',vObjectID,' - ',vEventID,ptext),'');  
        END IF;
    END IF; 
END
$$

And then your code:

MySqlScript script = new MySqlScript(connection, File.ReadAllText("script.sql"));
script.Delimiter = "$$";
script.Execute();

I am not 100% sure what native MySql syntax is, but when we perform similar functionality for Sql Server, we have to break the sql file into chunks based on the literal values (GO) that are only used by the query executor (Sql Server Management Console).

I suspect there may be similar information embedded in your request above, such as the DEFINE statement.

Knowing exactly what MySql complained about would help refine the solution.

How if you put your sql script in a stored procedure? If you still want use this way attach the sql file to application as file to the application resources (files .resx) and execute it like that:

MySql.Data.MySqlClient.MySqlCommand cmdMySQL = newMySqlConnection.CreateCommand();
cmdMySQL.CommandText = (System.String)globalResource.your_file_name;

Answer 4

You could run a separate Process to execute the script. For example:

Process.Start("mysql < script.sql");

You are probably going to need to play around with it a little depending on your environment to include paths to the mysql executable or the sql script.
