Read records from a table

Read existing records in a table using the API.

See also: Example: Copy updated records

URL

Use a URL in the following form to invoke the API:

You must pass the application access key using one of the methods described in Specify the application access key. For example, to pass it in the HTTP query string, use the following format:

https://api.appsheet.com/api/v2/apps/{appId}/tables/{tableName}/Action?applicationAccessKey=<applicationAccessKey>

Request body

The HTTP request body contains:

• The Action name Find.
• Optional properties such as Locale, Location, and Timezone.
  The Locale is used when validating Date, Time, DateTime, Decimal, Percent, and Price data values. For example, when Locale is en-US, date values must be entered in MM/DD/YYYY format. When Locale is en-GB, date values must be entered in DD/MM/YYYY format.
• The optional Selector property.

Examples

Read all rows

You can omit the Selector property and not specify any input Rows. This will return all rows in the table.

{
"Action": "Find",
"Properties": {
   "Locale": "en-US",
   "Location": "47.623098, -122.330184",
   "Timezone": "Pacific Standard Time",
   "UserSettings": {
      "Option 1": "value1",
      "Option 2": "value2"
   }
},
"Rows": [
]
}

Read selected rows

In the Selector property, you can specify an expression to select and format the rows returned.

For example, you can specify one of the following expressions:

• FILTER() to return keys to rows in a table or slice.
• ORDERBY() expression to control the sort order of the returned records. 
• SELECT() expression that yields a list of record key values. The records identified by the key values are returned in the Rows response. The SELECT() expression can refer to a slice.
• TOP() expression to limit the number of returned rows.

{
"Action": "Find",
"Properties": {
   "Locale": "en-US",
   "Location": "47.623098, -122.330184",
   "Selector": "Filter(People, true)",
   "Timezone": "Pacific Standard Time",
   "UserSettings": {
      "Option 1": "value1",
      "Option 2": "value2"
   }
},
"Rows": [
]
}

The following provides additional examples of the Selector property:

"Selector": "Filter(People, true)"

"Selector": "Filter(People, [Age] >= 21)"

"Selector": "Select(People[_ComputedKey], And([Age] >= 21, [State] = "CA"), true)"

"Selector": "OrderBy(Filter(People, [Age] >= 21), [LastName], true)"

"Selector": "Top(OrderBy(Filter(People, [Age] >= 21), [LastName], true), 10)"

"Selector": "Top(OrderBy(Select(People[_ComputedKey], And([Age] >= 21, [Date Hired] > "01/01/2016"), true), [LastName], false), 100)"

Read input rows

You can omit the Selector property and specify input Rows containing the key values of the records to be read. This will return all rows having matching key values from the table.

{
"Action": "Find",
"Properties": {
   "Locale": "en-US",
   "Location": "47.623098, -122.330184",
   "Timezone": "Pacific Standard Time",
   "UserSettings": {
      "Option 1": "value1",
      "Option 2": "value2"
   }
},
"Rows": [
{
"FirstName": "Jan",
"LastName": "Jones",
}
]
}

Security filters

The Find is performed under the identity of the application owner by default. Your can override this by specifying the RunAsUserEmail property in the request properties.

Security filters are applied when the Find is performed.

Response body

The API returns the rows in HTTP contents.

The returned records include all field values. This includes virtual fields and field values computed by worksheet formulas.
