What can you do with a search cursor?
Search cursors also support with statements to reset iteration and aid in removal of locks. However, using a del statement to delete the object or wrapping the cursor in a function to have the cursor object go out of scope should be considered to guard against all locking cases.
How can I get geometry from search cursor?
The order of values in the tuple matches the order of fields specified by the field_names argument. Geometry properties can be accessed by specifying the token SHAPE@ in the list of fields. Search cursors can be iterated using a for loop. Search cursors also support with statements to reset iteration and aid in removal of locks.
How does the search cursor work in ArcGIS?
Resets the cursor back to the first row. Use SearchCursor to step through a feature class, printing specific field values and the x,y coordinates of the point. Use SearchCursor to return a set of unique field values. Use SearchCursor to return attributes using tokens.
What to use instead of an asterisk in searchcursor?
Use an asterisk ( *) instead of a list of fields to access all fields from the input table (raster and BLOB fields are excluded). However, for faster performance and reliable field order, it is recommended that the list of fields be narrowed to only those that are actually needed. Raster fields are not supported.
What is the function of searchcursor in Java?
The SearchCursor function establishes a read-only cursor on a feature class or table. SearchCursor can be used to iterate through Row objects and extract field values. The search can optionally be limited by a where clause or by field and optionally sorted.
How does search cursor work in ArcGIS Pro?
Resets the cursor back to the first row. Use SearchCursor to step through a feature class and print specific field values and the x,y coordinates of the point. Use SearchCursor to return a set of unique field values. Use SearchCursor to return attributes using tokens.
How are search cursors iterated in ArcGIS help?
Search cursors can be iterated using a For loop. Search cursors also support With statements; using a With statement will guarantee close and release of database locks and reset iteration. The records returned by SearchCursor can be constrained to match attribute criteria and/or spatial criteria.
How can I use search cursor to access geometry?
Geometry properties can be accessed by specifying the token SHAPE@ in the list of fields. Search cursors can be iterated using a For loop. The records returned by SearchCursor can be constrained to match attribute criteria or spatial criteria. Accessing full geometry with SHAPE@ is an expensive operation.
