我尝试使用以下脚本将 mysqldump 文件转换为 Sqlite 3 兼容文件。
#!/bin/bash
if [ "x$1" == "x" ]; then
echo "Usage: $0 <dumpname>"
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' |
sed 's/\\r\\n/\\n/g' |
sed 's/\\"/"/g' |
sed 's/ "id" bigint(20) NOT NULL/ "id" integer primary key autoincrement/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"
else
echo "There were errors during conversion. Please review $1.err and $1.sql for details."
fi
尝试转换以下转储文件时出现以下错误:
DROP TABLE IF EXISTS "acos";
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;

"lft" int(10) DEFAULT NULL,
"rght" int(10) DEFAULT NULL,

FULLTEXT KEY "alias" ("alias")
);
