源码不太严谨，建议修改。

com.codingapi.txlcn.tc.core.transaction.txc.analy.PrimaryKeyListVisitor
这个类中 59 行
Object expression = ((Expression)expressions.get(i)).getASTNode().jjtGetValue();
这个方法，没有判空，可想而知，如果我一张表中没有数据 那就是 null.xxx
NullPointException
--- 望采纳。

Open com.codingapi.txlcn.tc.core.transaction.txc.analy.PrimaryKeyListVisitor and inspect line 59, especially the AST value access. Reproduce the empty-table case described in the issue and verify that it no longer raises a NullPointerException when the value is absent.
