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.
#!/bin/sh #### # NAME: convert-mysql-to-sqlite3.sh # AUTHOR: Matt Reid # DATE: 2011-03-22 # LICENSE: BSD #### 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.
