When preceded by NOT, it selects a record if it has a value outside the specified range. To edit a clause within a query, adjust values as necessary. You can automate the creation and execution of definition queries with Python by using a combination of ArcPy functions. Probably a better alternative that works even if the Start field contains dates in future months and you want all dates from the first day of the current month forward the query should be: You also have the alternative of using a definition query like below, but it is not dynamic. >= CURRENT_TIMESTAMP -+ INTERVAL 'HH' HOUR For feature classes and tables, you can use the UPPER or LOWER function to set the case for a selection. If mode is set to edit, the tolerance is always set to the full-resolution tolerance of the spatial reference regardless of what is passed in or set for the maxAllowableOffset. If you are not using such a data source, you can force the expression to use this format. The problem is, if you went back and opened the file in June and have added June features, you would now be showing both May and June results and would need to adjust the definition query for June. It looks like you can't use those functions in Pro, even if the DB itself would in a query. The examples below outline the different ways in which the INTERVAL syntax can be modified for the purposes of your query: There are some additional considerations. For example, I want to query all the birds spotted on or after June 1st, 2018, so I will format my query using greater than or equal to: Sightings >= DATE '2018-06-01'. formatted to display differently in both the table and a pop-up.

Fixed bins are, by contrast, always a specific unit of measurement (for example, 60 seconds in a minute, 24 hours in a day) regardless of where the date and time of the bin starts. The view value specifies that geometry coordinates should be optimized for viewing and displaying of data. Geographic Information Systems Stack Exchange is a question and answer site for cartographers, geographers and GIS professionals. The edit value can only be used when the supportsQuantizationEditMode layer property is true. When you calculate a date such as date_field = dateserial(02,8,20) and specify two digits for the year (02 in this case), your system's settings control which century is used.
So, call your layer "BORES" with source in FGDB, call date field "MUID" or change code above to suit your naming. To get the bins, you want to define your time zone as America/Log_Angeles and shift the time forward 8 hours by providing an offset. This can be done with the IN or ANY keyword. >= CURRENT_TIMESTAMP -+ INTERVAL 'DD HH:MI:SS(.FFF)' DAY TO SECOND Also, if you are using ArcSDE 10, you can use query layers to bring the views into your mxd.

Steve, your method hit the nail on the head! SQL-92 WHERE clause syntax on the fields in the layer is supported for most data sources. Our data is stored in SQL and we have a point feature class that is joined to the table through a view. Many of these are overlapping and have the same location ID. Some of the functions support datetime yyyy-mm-dd hh:mm:ss AM or PM. Returns the arcsine of float_exp as an angle, expressed in radians. This selects all records in the designated field that are between the current date and the current date with 30 added to the day. In the Choose Widget window that opens, select the widget and click OK. Optionally click Change widget icon to replace the default icon for this widget.

You will have to manually adjust the date in the query each time you want that answer, and who wants to do that? Wall shelves, hooks, other wall-mounted things, without drilling? Each type of date-time query must include a date function to make sure the query is treated in the proper way. It can be used with strings (comparison is based on alphabetical order), numbers, and dates. Subqueries that are performed on versioned ArcSDE feature classes and tables will not return features that are stored in the delta tables. If you are querying a date type field and have dateFieldsTimeReference set to a specific time zone, make sure your WHERE clause issues the time in that specific time zone. Included features can be specified by providing a time extent, where condition, and a spatial filter, similar to a query operation. You can define what information is returned using the statistics parameters. Returns the hour of the time in the given date (0-23). ArcGIS Pro uses the system short date format (numerical) to display dates. Greater than. Returns the largest integer less than or equal to numeric_exp. Returns the second of the time in the date. It may be extremely slow to execute on a large dataset. For the examples above I used the =operator, but any of the following comparison operators can be used in the where clause:>=, <=, >, <, <>.

Returns the position of the first character expression in the second character expression. Values range from 1-53 where the first week of the year is 1 and the last week of the year is 52 or 53, depending on the year. You can also use two digits for the year value when calculating dates. By default, daily bins start at 00:00:00 UTC. A file explorer window appears, allowing you to browse to a local image file to use as the widget icon. Fixed bins can use multiple units for these time widths. To give more examples of how you can use this, lets sayyou want all the bird sightings within the last 6 hours, the query would look like this:Sightings >= CURRENT_TIMESTAMP - 0.25.

The dateFieldsTimeReference property of the feature service identifies the time zone in which all dates are stored. Maybe setup a definition query on the feature class (in ArcMap) before you publish it? A scalar subquery returns a single value. It only takes a minute to sign up. In a database you'd need to use a date function supported by that database (and these are, Flake it till you make it: how to detect and deal with flaky tests (Ep. -> Date When a layer is shared as a feature layer or within a map image layer, only the active definition query is retained and honored.

The date field used to determine which bin each feature falls into. @Shea Good to hear - please mark the post as answered if you get a chance to let others know it is resolved. It should honor the filter you apply to the field, but of course this will require a process to re-publish the map to contain the updates. The time parameter defines a fixed starting point and ending point of the features based on the field used in binField. Double-sided tape maybe? It is possible to store only a time in the field when the underlying database actually uses a date-time field, but it is not recommended. You could successfully query with the following statements if the table you query contains date records with these exact time stamps (2007-05-29 00:00:00 or 2007-05-29 12:14:25): If you use other operators, such as greater than, less than, greater than or equal to, or less than or equal to, you don't have to designate the time, although you can if you want to be that precise.
