For example, you use this syntax using the Select By Attributes tool or with the Query Builder dialog box to set a layer definition query. Learn more about wildcards. The wildcards you use to query personal geodatabases are * for any number of characters and ? For example, this expression will select all the cities in a coverage with names starting with the letters M through Z: The not equal (<>) operator can also be used when querying strings. In most ArcGIS dialog boxes where you build a query expression, the name of the layer or table is supplied for you (or you select it from a drop-down list). In SQL, greater than operator is used to check whether the left-hand operator is higher than the right-hand operator or not.If left-hand operator higher than right-hand operator then condition will be true and it will return matched records. Example: MySQL not equal to (<>) operator. You also use SQL to select features programmatically. For example, you might add a Geodatabase layer containing cities around the world but only want the map to show cities with a population over 1 million. If a layer is not visible in the Create Features window when editing in ArcMap, this can be due to several reasons: - The layer was added to the map after a previous editing session. When you create definition query sets, you can create queries that work across several feature classes or individual queries for each feature layer. See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool. If you do not want NULLs, set it to “No”. For example: You can use the NULL keyword to select features and records that have null values for the specified field. You can click the button to enter the wildcard into the expression you're building.
