Simple MySQL: Converting ANSI SQL to SQLite3
+0 Vote Up -0 Vote Down

I was digging through some old project code and found this script. Sometimes one finds oneself in an odd situation and needs to convert regular SQL, say from a MySQL database dump, into SQLite3 format. There’s not too much else to say, but here is a script that helps with the process. It can likely be improved but this handles the items that came up during conversion on initial runs.

   echo "Usage: $0 "
cat $1 |

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          
   echo "There were errors during conversion.  Please review $1.err and $1.sql for details."
