Top Forums Shell Programming and Scripting Parse through ~21,000 Database DDL statements -- Fastest way to perform search, replace and insert Post 302805805 by Peasant on Saturday 11th of May 2013 07:42:58 AM

Code:
BEGIN {
IGNORECASE=1
}
/^\(/,/^\)/ { # lets find out the table name and fill array.
	if ( $1 !~ /\(|\)/ ) {
	if ( match($0,/(from [a-z_]+)/)) {
	table=substr($0,RSTART+5,RLENGTH-5)
	}
	a[$0]
	}
}

{
if (sub("WITH DATA","WITH NO DATA")) { rtn = 1 }
} 1 # do END (change) or print same file.

END {
if ( rtn > 0 ) {
print "INSERT INTO " table
for ( i in a ) {
	printf i
	}
	printf "; \n"
	}
}

Save as job.awk and run in scripts as awk -f job.awk yourinputfile

Hope that helps

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
