sql - Error with mysql procedures ERROR 1304 & ERROR 1305 -


I'm new to using processes and I do not seem to be working for my use of MySQL v5.1.36 I am using and using my code on a WAMPP server using MySQL Console. If I'm making the (again) process I get error # 1304 (42000). 

  mysql> DELIMITER // mysql & gt; Mysql & gt; Create method modx.getCRID (X XARAR (255), outside and INT) - & gt; BEGIN - & gt; DECLARE y INT; - & gt; Select in Y - & gt; From `Modx`.coverage_region - & gt; Where `coverage_region` name = x; - & gt; END // Error 1304 (42000): The action getCRID already exists in mysql & gt; Mysql & gt; DELIMITER;

However, if I try to use the process, I get error # 1305 (42000). 

  mysql> Use the modax; MySQL and gt; SET @crID = modx.getCRID ("southeast"); Error 1305 (42000): function modx.getCRID does not exist

If the process exists for one, then how can it not exist for another?

  1. I believe that there are problems

The first error occurs because you have an existing process Trying to recreate If you wanted to leave the process before, you do not get this error,
  • The second error is that the processes are applied with a call statement, while the function is in reference to the function reference is applied. You must not define a procedure, there is no action () to say:

    • To support the UDF (User-Defined Function) also the CREATE FUNCTION statement in MySQL is used to. See Section 21.2, "Adding New Functions to MySQL" An UDF can be considered as an external archive function. Archived works share their namespace with UDF.

    To open a stored procedure, use the call statement (see section 12.2), section 9.2, "Function name parsing and resolution", for the rules, see how the server performs different types of functions. Explains the context. .1, "call syntax"). To open the stored function, view it in Expression function gives a value during the expression evaluation.

    Eclipse CDT variable colors in editor -

    I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
