Error PLS-00103 compiling user-defined function in Oracle -


I am trying to create a user-defined function in Oracle which will return on DATE, when a date sub-word Giving a text argument will be given. I have tried some ways of writing this, and all start throwing the same error: 

  create or function lm_date_convert REPLACE (lm_date_in (50) in VARCHAR2) Date of return determinant returns (IS TO_DATE (REGEXP_REPLACE (lm_date_in, '([[digits:]] {2}) [- /.] * ([[Issue:]] {2}) [- /.] * ([[: Points :]] {4}) ',' \ 3- \ 1- \ 2 '),' YYYY-MM-DD '); End;

Error:

compiled Lm_date_convert function 1/46
PLS-00103: symbol "(" While expecting one of the following: < / P>

: =.), Indicating "% of the default character emblem" "symbol": = "was replaced for" ("to continue.

Any ideas on this, and general UDF writing tips (and good references) are welcome!

We restrict datatype The parameters can not be specified in time stored procedures. That is, just use VARCHAR2 instead of VARCHAR2 (50).

Just to prove I 'm your problem arises ... < / P> 

  SQL> Create or function lm_date_convert REPLACE (lm_date_in (50)) in VARCHAR2 2 Date of return deterministic 3 4 Returns (TO_DATE (REGEXP_REPLACE (lm_date_in, '([[: Numbers:]] {2}) - * ([[:: points:]] {2}) [/.] [- /.] * ([[:: Points:]] {4}) ',' \ 3 \ 1- \ 2 '),' YYYY-MM-DD '); 5 end, 6 / warning.

"> SQL

to fix it now : 

  SQL & gt; ed 1 afiedt.buf file can be written or REPLACE FUNCTION lm_date_convert (in VARCHAR2 lm_date_in) 2 return date deterministic 3 start 4 profit i.e. (TO_DATE (REGEXP_REPLACE) (Lm_date_in, '([ [: Points:]] {2}) [- /.] * ([[: Issue:]] {2}) [- /.] * ([[: Issue:]] {4}) ',' \ 3- \ 1- \ 2 '),' 5 'end, SQL> Create 1 or function lm_date_convert REPLACE (lm_date_in in VARCHAR2) 2 return date deterministic 3 start 4 profit ie (TO_DATE (REGEXP_REPLACE (lm_date_in, '([[digits:]] {2}) [- /.] * ([[:: Digits:]] {2}) [- /.] * ([[: ]] {4}) ',' \ 3 \ 1- \ sql>

"If you really want a VARCHAR2 (50)) then Announce a type of VARCHAR2 (50) and use the type. "

Declaring a SQL TYPE to implement shaping is a bit of overkill. The YPE in PL / SQL but their size does not actually apply to stored process signatures. There are ways to work in this form.

On the one hand, why are you using Reggae to solve this problem? Or rather, what problem do you try to solve? Which are TO_CHAR and TO_DATE Sector can not be solved with? Format very forgiving of Oracle with masks

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....
