问题 I am trying to write an sql script in toad for oracle version 9.5 that when run will allow the user to select data from a txt file from the c drive where the parameters / variables are entered. The version of oracle is 10g 回答1: Sounds like an Oracle external directory is perfect for the job. Keep in mind this approach is fraught with difficulties if this is a text file that users can write to. Users will do a hundred things you never believed possible that will cause errors and more.

问题 Like Oracle, SQL Server supports parameter defaults in stored procedures. Oracle syntax: CREATE OR REPLACE PROCEDURE p_default ( p_in_number IN number := 0, p_out_number OUT number, p_in_varchar IN varchar2 := '0', p_out_varchar OUT varchar2, p_in_date IN date := date '1981-07-10', p_out_date OUT date ) SQL Server syntax: CREATE PROCEDURE p_default ( @p_in_number INTEGER = 0, @p_out_number INTEGER OUT, @p_in_varchar VARCHAR(10) = '0', @p_out_varchar VARCHAR(10) OUT, @p_in_date DATE = '1981-07

问题 Like Oracle, DB2 supports parameter defaults in stored procedures.

问题 Through the SqlParameter class (for C#) I can see parameters in a stored procedure. How do you know if a parameter is mandatory or not? I tried using IsNullable but it's always false. Maybe I'm writing a wrong stored procedure, or is IsNullable meant just to set? Thanks 回答1: "Optional" simply means there is a default for stored procedure parameters.

问题 I've been doing PHP for a while now, never needed assistance, but totally confused this time. I have a single line of code with one echo statement. Problem: URL parameters are automatically assuming PHP variable values of the same name. For example, I have a URL with a parameter named 'var_name' like this: http://www.example.com?var_name=abc123 and a 1-line PHP script with a variable named 'var_name', like this: echo $var_name; then I get output on the page of: abc123 This is the only code in

问题 I've followed Cocoon's instructions for creating a nested form for a has_many association but there's one thing that I can't seem to figure out. I'm able to add an existing genre to my project but when it comes to creating a completely new one the parameters for my genres aren't being permitted. When I refer to my rails console to debug the issue this is the message I receive upon update: Unpermitted parameters: genre_attributes What's strange is I've permitted both my join table genreships

问题 There are some answers on stackoverflow, but no one fits my needs :( I'm trying to conditionally build a <ui:param /> for my parent template with JSTL. Something like this: <ui:composition ... template="template.xhtml"> <c:if test="#{condition}"> <ui:param name="parameter" value="parameterValue" /> </c:if> <ui:define name="insertName"> {...} </ui:define> </ui:composition> I tried with both namespaces for JSTL: http://java.sun.com/jstl/core and http://java.sun.com/jsp/jstl/core, but neither
