查询多个值

Question

我正在尝试按多个值进行过滤，但我似乎无法使用 and 子句（例如 filter1 和 filter 2 ...等）：

显示数据库名称为 'testing'

的快照

aws rds describe-db-snapshots --include-shared --query 'DBSnapshots[?DBInstanceIdentifier==`testing`].{DBNAME:DBInstanceIdentifier,SNAPSHOT:DBSnapshotIdentifier}'
[
    {
        "SNAPSHOT": "test1",
        "DBNAME": "testing"
    },
    {
        "SNAPSHOT": "test2",
        "DBNAME": "testing"
    },
    {
        "SNAPSHOT": "test3",
        "DBNAME": "testing"
    },
    {
        "SNAPSHOT": "test4",
        "DBNAME": "testing"
    }
]

显示名为 'test1'

的快照

$ aws rds describe-db-snapshots --include-shared --query 'DBSnapshots[?DBSnapshotIdentifier==`test1`].{DBNAME:DBInstanceIdentifier,SNAPSHOT:DBSnapshotIdentifier}'
[
    {
        "SNAPSHOT": "test1",
        "DBNAME": "testing"
    },
        {
        "SNAPSHOT": "test1",
        "DBNAME": "testing2"
    }
]

显示数据库测试中名为 test1 的快照

aws rds describe-db-snapshots --include-shared --query 'DBSnapshots[?DBInstanceIdentifier==`testing`][?DBSnapshotIdentifier==`test1`].{DBNAME:DBInstanceIdentifier,SNAPSHOT:DBSnapshotIdentifier}'
[]

如何实现？

Answer 1

您需要与 AND expression 一起工作，这样才能成功

$ aws rds describe-db-snapshots --include-shared \
--query 'DBSnapshots[?(DBInstanceIdentifier==`testing` && DBSnapshotIdentifier==`test1`)].{DBNAME:DBInstanceIdentifier,SNAPSHOT:DBSnapshotIdentifier}'
