Numeric values are always listed using the point as the decimal delimiter regardless of your regional settings. To switch between active definition queries, follow these steps: With the layer selected in the Contents pane, under Feature Layer, on the Data tab, in the Definition Query group, click to open the Layer Properties dialog box with its Definition Query tab open. Any DefinitionExpression set in the LayerDescription or StandaloneTableDescription will override any definition query set in the source map. That means that a definition query impacts not only drawing, but also which features appear in the layer's attribute table, can be selected, labeled, identified, and processed by geoprocessing tools. For example: Instead of having the users [right click > properties > definition query > create SQL query] they would [double click tool > specify the expression value]. The Definition Queries tab on the Feature Display Settings dialog box provides you with a way to determine which features appear on a map or chart. This means you can construct a number of related queries for a certain scenario and apply them all at once.

To apply definition queries with a common name to multiple layers simultaneously, follow these steps: When a layer is shared as a feature layer or within a map image layer, only the active definition query is retained and honored. SQL expressions are used in many parts of ArcGIS and its extensions to define a subset of data on which to perform some operation. Because you are selecting columns as a whole, you cannot restrict the SELECT to return only some of the columns in the corresponding table because the SELECT * syntax is hard-coded.
