If you're running on Sun/Solaris you might need to use nawk rather than awk. Older versions, including the default awk on Sun boxen (If I remember correctly), have smallish line length restrictions.

You can let awk find your table names and count them with something like this:

Code:
awk -v RS=" " '
    {
        n=split( $0, a, "\n" );
        for( i = 1; i <= n; i++ )
            if( (m = split( a[i], b, "." )) == 2 && b[1] == "ABCD" )
                count[b[2]]++;     # count each occurrence of table name
    }
    END {
        for( c in count )   #print each table and count
            printf( "%5d %s\n", count[c], c );
    } ' input-file-name |sort  -k 1nr,1

Setting the record seperator (RS) to blank, and splitting the input line on newline, might get you round the long line issue. Splitting each token and doing a direct compare for the database name should be quicker than a regexp match since your pattern is (I assume) a fixed string.

ucblinks

ucblinks(1B)					     SunOS/BSD Compatibility Package Commands					      ucblinks(1B)

NAME

       ucblinks - adds /dev entries to give SunOS 4.x compatible names to SunOS 5.x devices

SYNOPSIS

       /usr/ucb/ucblinks [-e rulebase] [-r rootdir]

DESCRIPTION

       ucblinks  creates symbolic links under the /dev directory for devices whose SunOS 5.x names differ from their SunOS 4.x names. Where possi-
       ble, these symbolic links point to the device's SunOS 5.x name rather than to the actual /devices entry.

       ucblinks does not remove unneeded compatibility links; these must be removed by hand.

       ucblinks should be called each time the system is reconfiguration-booted, after any new SunOS 5.x links that are needed have been  created,
       since the reconfiguration may have resulted in more compatibility names being needed.

       In  releases prior to SunOS 5.4, ucblinks used a  nawk rule-base to construct the SunOS 4.x compatible names. ucblinks no longer uses  nawk
       for the default operation, although  nawk rule-bases can still be specifed with the -e option.  The  nawk rule-base equivalent to the SunOS
       5.4 default operation can be found in /usr/ucblib/ucblinks.awk.

OPTIONS

       -e rulebase     Specify rulebase as the file containing nawk(1) pattern-action statements.

       -r rootdir      Specify rootdir as the directory under which dev and devices will be found, rather than the standard root directory /.

FILES

       /usr/ucblib/ucblinks.awk        sample rule-base for compatibility links
