[英]Left Outer Join in SQLite
I have two tables, the first having more rows than the second. 我有两个表,第一个表比第二个表有更多的行。
I am trying to use a LEFT OUTER JOIN to put these two tables together in SQLite but I keep getting an error message. 我正在尝试使用LEFT OUTER JOIN在SQLite中将这两个表放在一起,但我一直收到错误消息。
The query I am running is: 我正在运行的查询是:
SELECT a.object, a.id, b.objectName
FROM tableOne a
LEFT OUTER JOIN tableTwo b ON a.id=b.id
The error message I get is: 我收到的错误消息是:
Exception Name: NS_ERROR_FAILURE
Exception Message: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [mozIStorageConnection.createStatement]
Isolate table names: 隔离表名称:
SELECT a.object,
a.id,
b.objectName
FROM "tableOne" a
LEFT OUTER JOIN "tableTwo" b
ON a.id=b.id
