Converting MySQL Dump SQL to Sqlite3 DB

Importing a MySQL dump SQL file into a SQLite3 database requires conversion to ensure compatibility.

The provided shell script offers an automated way to convert the dump file:

#!/bin/sh
# Usage: $0 

if [ "x$1" == "x" ]; then
   echo "Usage: $0 "
   exit
fi
cat $1 |
grep -v ' KEY "' |
grep -v ' UNIQUE KEY "' |
grep -v ' PRIMARY KEY ' |
sed '/^SET/d' |
sed 's/ unsigned / /g' |
sed 's/ auto_increment/ primary key autoincrement/g' |
sed 's/ smallint([0-9]*) / integer /g' |
sed 's/ tinyint([0-9]*) / integer /g' |
sed 's/ int([0-9]*) / integer /g' |
sed 's/ character set [^ ]* / /g' |
sed 's/ enum([^)]*) / varchar(255) /g' |
sed 's/ on update [^,]*//g' |
perl -e 'local $/;$_=<>;s/,\n\)/\n\)/gs;print "begin;\n";print;print "commit;\n"' |
perl -pe '
  if (/^(INSERT. ?)\(/) {
     $a=$1;
     s/\\'\''/'\'\''/g;
     s/\\n/\n/g;
     s/\),\(/\);\n$a\(/g;
  }
  ' > $1.sql
cat $1.sql | sqlite3 $1.db > $1.err
ERRORS=`cat $1.err | wc -l`
if [ $ERRORS == 0 ]; then
  echo "Conversion completed without error. Output file: $1.db"
  rm $1.sql
  rm $1.err
    rm tmp
else
   echo "There were errors during conversion.  Please review $1.err and $1.sql for details."
