For information about subprograms in PL/SQL blocks, see "Using Local PL/SQL Procedures and Functions in PL/SQL Blocks". Stored procedures and functions are the key to modular, reusable PL/SQL code. Wherever you might use a JAR file in Java, a module in Perl, a shared library in C++, ...
However, the significance of disulfidptosis-related Long non-coding RNAs (DRLs) in the prognosis and immunotherapy of HCC remains unclear. Based on The Cancer Genome Atlas (TCGA) database, we used Least Absolute Shrinkage and Selection Operator (LASSO) and Cox regression model to construct DRL...
When we need to reference the particular element, we can use -> operator. my $name = $hash_ref->{name}; Make reference to an anonymous Perl hash as shown below. my $hash_ref = { 'name' => "Harsha", 'designation' => "Manager" ...
