Hammer & Screwdriver Convert Update statement into Insert statement in UNIX using awk, sed....

Hi folks,

I have a scenario to convert the update statements into insert statements using shell script (awk, sed...) or in database using regex.

I have a bunch of update statements with all columns in a file which I need to convert into insert statements.

UPDATE TABLE_A SET COL1=1 WHERE COL2 is NULL AND COL2=3;

OUTPUT Should be:

INSERT INTO TABLE_A (COL1,COL2,COL3) VALUES (1,NULL,3);

Many Thanks.

PPI::Statement::Compound(3)				User Contributed Perl Documentation			       PPI::Statement::Compound(3)

NAME
PPI::Statement::Compound - Describes all compound statements SYNOPSIS
# A compound if statement if ( foo ) { bar(); } else { baz(); } # A compound loop statement foreach ( @list ) { bar($_); } INHERITANCE
PPI::Statement::Compound isa PPI::Statement isa PPI::Node isa PPI::Element DESCRIPTION
"PPI::Statement::Compound" objects are used to describe all current forms of compound statements, as described in perlsyn. This covers blocks using "if", "unless", "for", "foreach", "while", and "continue". Please note this does not cover "simple" statements with trailing conditions. Please note also that "do" is also not part of a compound statement. # This is NOT a compound statement my $foo = 1 if $condition; # This is also not a compound statement do { ... } until $condition; METHODS
"PPI::Statement::Compound" has a number of methods in addition to the standard PPI::Statement, PPI::Node and PPI::Element methods. type The "type" method returns the syntactic type of the compound statement. There are four basic compound statement types. The 'if' type includes all variations of the if and unless statements, including any 'elsif' or 'else' parts of the compound statement. The 'while' type describes the standard while and until statements, but again does not describes simple statements with a trailing while. The 'for' type covers the C-style for loops, regardless of whether they were declared using 'for' or 'foreach'. The 'foreach' type covers loops that iterate over collections, regardless of whether they were declared using 'for' or 'foreach'. All of the compounds are a variation on one of these four. Returns the simple string 'if', 'for', 'foreach' or 'while', or "undef" if the type cannot be determined. TO DO
