Question

我正在尝试选择默认架构中的所有表格，＆＃39; PUBLIC＆＃39;使用TABLE_CATALOG和TABLE_SCHEMA的预准备语句和参数。当我创建一个准备好的语句时，我从系统中得到一个错误，它没有任何意义。如果我在没有TABLE_SCHEMA的情况下指定TABLE_CATALOG，它可以完美地工作。另外，如果我在没有TABLE_CATALOG的情况下指定TABLE_SCHEMA，它也可以正常工作。我在这里做错了吗？

SELECT 
    TABLE_CATALOG, 
    TABLE_SCHEMA, 
    TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE
    TABLE_CATALOG = ?, TABLE_SCHEMA = ?

线程中的异常＆＃34; main＆＃34; org.h2.jdbc.JdbcSQLException：SQL中的语法错误

此

TABLE_CATALOG = ?, TABLE_SCHEMA = ?

应该是

TABLE_CATALOG = ? AND TABLE_SCHEMA = ?
