Method Details

parseWhereClause Method parseWhereClause(clause, fieldsIndex, timeZone){Promise<WhereClause>}

Parses the given where clause string and returns an instance of WhereClause when resolved. The WhereClause object can be used repeatedly against different features, to test if they individually meet the condition. The parser does not parse a whole SQL statement (ie. SELECT X… WHERE…). It only parses the expression after the where token.

Parameters

clause String

The SQL where clause expression.

fieldsIndex FieldsIndex

The fields index of the layer. The fields index is used to match the fields found in the where clause against the service, to fix casing for example.

timeZone String

optional

Default Value: "UTC"

The time zone in which SQL date functions are evaluated. The default is "UTC". This parameter only accepts IANA time zones.

Returns

Type	Description
Promise<WhereClause>	Parses a string where clause and returns a promise that resolves to an object with the WhereClause specification.

Examples

sql.parseWhereClause("POPULATION > 100000", layer.fieldsIndex)
.then(function(clause){
  let testResult = clause.testFeature(
    new Graphic({
      attributes: {
        POPULATION: 300000
      }
    })
  );
  console.log(testResult); // prints true
});

sql.parseWhereClause(
  "START_TIME BETWEEN TIMESTAMP '2023-01-01 00:00:00' AND TIMESTAMP '2023-12-31 23:59:59'",
  layer.fieldsIndex
)
.then(function(clause){
  const utcDate = Date.UTC(2023, 0, 1, 0, 0, 0);
  let testResult = clause.testFeature(
    new Graphic({
      attributes: {
        START_TIME: utcDate
      }
    })
  );
  console.log(testResult); // true
});
