Queries files in a dataset by performing a simple query operation. The operation supports logical expressions.
Operation description
- Before you call this operation, make sure that you are familiar with the billing of Intelligent Media Management (IMM).****
- Before you call this operation, make sure that you have indexed file metadata into the dataset automatically by calling the CreateBinding operation or manually by calling the IndexFileMeta or BatchIndexFileMeta operation.
- The sample response is provided for reference only. The metadata type and content in your response may differ based on factors such as the workflow template configurations. For any inquiries, join the DingTalk chat group (ID: 31690030817) and share your questions with us.
Limits
- Each query returns information about up to 100 files.
- Each query returns up to 2,000 aggregations.
- A subquery supports up to 100 conditions.
- A subquery can have a maximum nesting depth of 5 levels.
Example query conditions
- Retrieve JPEG images larger than 1,000 pixels:
{
"SubQueries":[
{
"Field":"ContentType",
"Value": "image/jpeg",
"Operation":"eq"
},
{
"Field":"ImageWidth",
"Value":"1000",
"Operation":"gt"
}
],
"Operation":"and"
}
- Search
oss://examplebucket/path/
for objects that have theTV
orStereo
label and are larger than 10 MB in size:
TV
or Stereo
label. The two labels are specified as separate objects in the Labels
fields.
{
"SubQueries": [
{
"Field": "URI",
"Value": "oss://examplebucket/path/",
"Operation": "prefix"
},
{
"Field": "Size",
"Value": "1048576",
"Operation": "gt"
},
{
"SubQueries": [
{
"Field": "Labels.LabelName",
"Value": "TV",
"Operation": "eq"
},
{
"Field": "Labels.LabelName",
"Value": "Stereo",
"Operation": "eq"
}
],
"Operation": "or"
}
],
"Operation": "and"
}
- Exclude images that contain a face of a male over the age of 36:
nested
operator to specify that the conditions are met on the same element.
{
"Operation": "not",
"SubQueries": [{
"Operation": "nested",
"SubQueries": [{
"Operation": "and",
"SubQueries": [{
"Field": "Figures.Age",
"Operation": "gt",
"Value": "36"
}, {
"Field": "Figures.Gender",
"Operation": "eq",
"Value": "male"
}]
}]
}]
}
- Query JPEG images that have both custom labels and system labels:
{
"SubQueries":[
{
"Field":"ContentType",
"Value": "image/jpeg",
"Operation":"eq"
},
{
"Field":"CustomLabels.test",
"Operation":"exist"
},
{
"Field":"Labels.LabelName",
"Operation":"exist"
}
],
"Operation":"and"
}
You can also perform aggregate operations to collect and analyze different data based on the specified conditions. For example, you can calculate the sum, count, average value, or maximum value of all files that meet the query conditions. You can also calculate the size distribution of images that meet the query conditions.
