Add Field

Adds a new field to a table or the table of a feature class, feature layer, and/or rasters with attribute tables.

يضيف حقلاً جديدًا إلى جدول أو جدول فئة المعالم و / أو طبقة المعالم و / أو البيانات النقطية بجداول البيانات الجدولية.

1. Input Table جدول الإدخال

The input table to which the specified field will be added. The field will be added to the existing input table and will not create a new output table.

جدول الإدخال الذي سيتم إضافة الحقل المحدد إليه. ستتم إضافة الحقل إلى جدول الإدخال الحالي ولن يتم إنشاء جدول إخراج جديد.

Fields can be added to feature classes in geodatabases, shapefiles, stand-alone tables, rasters with attribute tables, and layers.

يمكن إضافة الحقول إلى فئات المعالم في قواعد البيانات الجغرافية ، وملفات الأشكال ، والجداول المستقلة ، والنقطية مع جداول البيانات الجدولية ، والطبقات.

Field Name

The name of the field that will be added to the input table.

Field Type

The field type of the new field.

·      TEXT—Any string of characters.

·      FLOAT— Fractional numbers between -3.4E38 and 1.2E38.

·      DOUBLE— Fractional numbers between -2.2E308 and 1.8E308.

·      SHORT— Whole numbers between -32,768 and 32,767.

·      LONG— Whole numbers between -2,147,483,648 and 2,147,483,647.

·      DATE—Date and/or time.

·      BLOB—Long sequence of binary numbers. You need a custom loader or viewer or a third-party application to load items into a BLOB field or view the contents of a BLOB field.

·      RASTER—Raster images. All ArcGIS software-supported raster dataset formats can be stored, but it is highly recommended that only small images be used.

·      GUID—Globally unique identifier.

Field Precision (optional)

The number of digits that can be stored in the field. All digits are counted no matter what side of the decimal they are on.

Field IsNullable (optional)

Specifies whether the field can contain null values. Null values are different from zero or empty fields and are only supported for fields in a geodatabase.

·      Checked—The field will allow null values. This is the default.

·      Unchecked—The field will not allow null values.

Field IsRequired (optional)

Specifies whether the field being created is a required field for the table and is only supported for fields in a geodatabase.

·      Unchecked—The field is not a required field. This is the default.
