问题是这样的，现在需要做一个流程表单管理，新建表单的时候创建这个表单的数据表。
那创建触发器的时候。我拼接sql语句的 代码是这么写的

StringBuffer sql = new StringBuffer();
		String TRGName = "TRG_"+formKey;//触发器名
		sql.append("CREATE OR REPLACE TRIGGER "+TRGName+" ");
		sql.append("BEFORE INSERT ON "+formKey+" ");
		sql.append("FOR EACH ROW ");
		sql.append("BEGIN ");
		sql.append("  SELECT "+seqName+".NEXTVAL INTO:NEW."+PKName+" FROM DUAL; ");
		sql.append("END;");
		return sql.toString();

语句在plsql中运行是正常的。
但是执行的时候却报错了。
