4. 參照内表条件进行查询 内表可以用来临时存放多条数据,OPEN SQL允许以内表数据作为查询条件,語法如下: SELECT <f1...fn> FROM <dbtab> FOR ALL ENTRIED IN WHERE... TABLES:spfli,sflight. DATA:BEGIN OF xpfli OCCURS 0, carrid LIKE spfli-carrid, connid LIKE spfli-connid, END OF xpfli. ...

Both SQL and noSQL databases are supported, from MySQL, PostgreSQL, SQL Server, MongoDB, SQLite, to CockroachDB. The author of DbGate says this was his passion project because he couldn't find a SQL client for Linux. He had built SQL clients for Windows in the past, so this was ...
这是sqlite在Android系统上的一个bug,在需要建立索引的sql语句频繁执行时,会发生这个异常。 (如果你是在SQLiteDatabase执行open()时看到的这个exception,那应该是线程冲突的问题,跟这篇文章讲的不是同一个) 根本原因是sqlite临时文件目录不可用。 解决方案是第一次建立连接时设置临时文件目录。
register_for_idb(sqlFS); SQL.FS.mkdir('/sql'); SQL.FS.mount(sqlFS, {}, '/sql'); const path = '/sql/db.sqlite'; if (typeof SharedArrayBuffer === 'undefined') { let stream = SQL.FS.open(path, 'a+'); await stream.node.contents.readIfFallback(); SQL.FS.close(stream); }...
