In most database management systems, you can modify field properties in a table by using the ALTER TABLE statement followed by the MODIFY COLUMN clause. This allows you to change parameters such as data type, size, nullability, and constraints for a specific field in the table. Remember to ensure that any modifications do not violate existing data integrity rules.

How can the periodic table identify the properties of chemical families?
Periodic table group elements with same properties together. Hence their properties can be identified.
Who first gave the concept of periodicity?
The concept of periodicity was first introduced by Dmitri Mendeleev when he created the periodic table in 1869, which arranged the elements based on their atomic mass and properties. Mendeleev's table allowed for the prediction of the properties of undiscovered elements and is considered a landmark achievement in the field of chemistry.
What were the five properties Medeleev used in his table?
The five properties Mendeleev used in his table were atomic mass, chemical properties, valency (oxidation state), color, and density.

What is one property that you can't find on the periodic table?
The physical properties are not listed in periodic table. The properties like density is not listed.These can't be found on periodic table.
How is a default value set in MS Access?
When you provide a default value for a field in Access, Access will automatically insert this value into the field when a record is inserted that has no value (NULL) for this field. Default values are used when there is a sensible default for a field.
What is the definition of Field Properties in computer subjects?
While creating a table in the design view,every field has some specific features,called properties,associated with it.
In VB.NET what method is used to modify a table?
SQL UPDATE statement is used to modify a record in a table.
How can you change column in the table?
ALTER TABLE mytab MODIFY (mycol <modifications>)
What is field property in database?
In a database, a field property defines the characteristics of a specific field within a table. These properties can include data type (such as text or numeric), length constraints, default values, and whether the field is required or allows null values. Field properties help ensure data integrity and consistency within the database.
What is difference between alter and modify on oracle?
MODIFY is a clause used within an ALTER statement, such as ALTER TABLE, ALTER INDEX or ALTER MATERIALIZED VIEW, etc. That is, MODIFY isn't a command by itself. For example, you might change the length of a text column in a table with the following: ALTER TABLE employee MODIFY (email_address VARCHAR(132));
Which view is used to create a table or to modify the structure of the table?
Design view.
When designing a table why is it important to place field properties within each field?
Fields specify how a field can work, what kinds of data can be put in to a field size and other things. You need to specify formats for numbers and dates. You need to specify the size of text fields. There are many optional properties which can prove useful in different situations. Doing validation on a field can be useful to reduce errors. You can ensure data is entered into a field. There are so many other things that properties do. So they are an essential part of designing a field in a database.
What is a vulnerability of ActiveX?
ActiveX controls can modify the properties of objects in an application.
Can an indexer modify the name field by highlighting the existing name and typing in a name?
An indexer can modify the name field by highlighting the existing name and typing in a new name.
How can the periodic table identify the properties of chemical families?
Periodic table group elements with same properties together. Hence their properties can be identified.
How is the position on the periodic table related to the chemical properties of an element?
Position of Periodic Table describes chemical properties. it is estimated from its position in table.
