Dear all,
How can i unset arrays. I mean all the subscripts including the array after using them.
Could you direct me to some links of array memory handling in the korn shell.

I've noticed something interesting in C++ programming. I've always done tricky stuff with pointers and references to have functions deal with arrays. Doing exercises again out of a C++ book has shown me an easier way, I didn't even know was there. It's weird to me.
When dealing with arrays, it... (4 Replies)

rdf::query::compiler::sql
RDF::Query::Compiler::SQL(3pm) User Contributed Perl Documentation RDF::Query::Compiler::SQL(3pm)NAME
RDF::Query::Compiler::SQL - Compile a SPARQL query directly to SQL.
VERSION
This document describes RDF::Query::Compiler::SQL version 2.908.
METHODS
"new ( $parse_tree )"
Returns a new compiler object.
"compile ()"
Returns a SQL query string for the specified parse tree.
"emit_select"
Returns a SQL query string representing the query.
"limit_clause"
Returns a SQL LIMIT clause, or an empty string if the query does not need limiting.
"order_by_clause"
Returns a SQL ORDER BY clause, or an empty string if the query does not use ordering.
"variable_columns ( $var )"
Given a variable name, returns the set of column aliases that store the values for the column (values for Literals, URIs, and Blank
Nodes).
"add_variable_values_joins"
Modifies the query by adding LEFT JOINs to the tables in the database that contain the node values (for literals, resources, and blank
nodes).
"patterns2sql ( @triples, $level, %args )"
Builds the SQL query in instance data from the supplied @triples. $level is used as a unique identifier for recursive calls.
%args may contain callback closures for the following keys:
'where_hook'
'from_hook'
When present, these closures are used to add SQL FROM and WHERE clauses to the query instead of adding them directly to the object's
instance data.
"expr2sql ( $expression, $level, %args )"
Returns a SQL expression for the supplied query $expression. $level is used as a unique identifier for recursive calls.
%args may contain callback closures for the following keys:
'where_hook'
'from_hook'
When present, these closures are used to add necessary SQL FROM and WHERE clauses to the query.
"_mysql_hash ( $data )"
Returns a hash value for the supplied $data string. This value is computed using the same algorithm that Redland's mysql storage
backend uses.
"_mysql_node_hash ( $node )"
Returns a hash value (computed by "_mysql_hash" for the supplied $node. The hash value is based on the string value of the node and
the node type.
"qualify_uri ( $uri )"
Returns a fully qualified URI from the supplied $uri. $uri may already be a qualified URI, or a parse tree for a qualified URI or
QName. If $uri is a QName, the namespaces defined in the query parse tree are used to fully qualify.
"add_function ( $uri, $function )"
Associates the custom function $function (a CODE reference) with the specified URI, allowing the function to be called by query
FILTERs.
"get_function ( $uri )"
If $uri is associated with a query function, returns a CODE reference to the function. Otherwise returns "undef".
