How can I create a MySql function in C#? -


i'm trying create mysql function in c#. reason i'm doing because want loop through multiple mysql databases , create function in each one.

the problem mysqlcommand not delimiter syntax required create function. script below executes fine in mysql clients, not work in context:

delimiter // drop function if exists cleandate // create function cleandate(mydate date)  returns date reads sql data  begin return  (case when mydate <= '1900-01-01' '1900-01-01' when mydate = '0000-00-00' '1900-01-01'          when date_format(mydate, '%y') = '0000' '1900-01-01'         when date_format(mydate, '%m') = '00' '1900-01-01'         when date_format(mydate, '%d') = '00' '1900-01-01'         else mydate          end); end//

the c# code trying implement this(assuming connstrings list of strings):

foreach(var connstring in connstrings) {     // create connection database     mysql.data.mysqlclient.mysqlconnection dbconn = new mysql.data.mysqlclient.mysqlconnection(connstring);      mysqlcommand cmd = dbconn.createcommand();     cmd.commandtext = @"[same script here]";      try     {         dbconn.open();         cmd.executenonquery();     }     catch (exception erro)     {         console.writeline(erro.tostring());                         } }

i "syntax error near delimiter //" when run though. ideas how can achieve this?

the mysql connector offers mysqlscript class can used in place of mysqlcommand when dealing executing multiple statements , setting delimiters.

adapted example: 

foreach(var connstring in connstrings) {     mysqlconnection dbconn = new mysqlconnection(connstring);      try     {         dbconn.open();          mysqlscript script = new mysqlscript(dbconn);          script.query = @"[same script here]";         script.delimiter = @"//";         script.execute();     }     catch (exception error)     {         console.writeline(error.tostring());                         } }

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
