{code}
I override MysqlSqlDialect quoteStringLiteral function to fix it , but i think
it's not a good solution
{code:java}
@Override
public void quoteStringLiteral(StringBuilder buf, String charsetName, String
val) {
if (charsetName != null) {
buf.append("_");
buf.append(charsetName);
}
buf.append(literalQuoteString);
buf.append(val.replace(literalEndQuoteString, literalEscapedQuote));
buf.append(literalEndQuoteString);
}
