For convenience, the GRANT statement provides two shortcuts that you can use when granting many privileges or when granting them to many users. Instead of specifically listing all of the privileges available for a particular object, you can use the keywords ALL PRIVILEGES. This GRANT statement gives Sam Clark, the vice president of sales, full access to the SALESREPS table: Give all privileges on the SALESREPS table to Sam Clark.

The SQL1 standard allows you to grant the UPDATE privilege for individual columns of a table or view, and the SQL2 standard allows a column list for INSERT and REFERENCES privileges as well. The columns are listed after the UPDATE, INSERT, or REFERENCES keyword and enclosed in parentheses. Here is a GRANT statement that allows the orderprocessing department to update only the company name and assigned salesperson columns of the CUSTOMERS table: Let order-processing users change company names and salesperson assignments.
GRANT UPDATE (COMPANY, CUST_REP) ON CUSTOMERS TO OPUSER
If the column list is omitted, the privilege applies to all columns of the table or view, as in this example: Let accounts receivable users change any customer information.
GRANT UPDATE ON CUSTOMERS TO ARUSER
The ANSI/ISO standard does not permit a column list for the SELECT privilege; it requires that the SELECT privilege apply to all of the columns of a table or view. In practice, this isn t a serious restriction. To grant access to specific columns, you first define a view on the table that includes only those columns and then grant the SELECT privilege only for the view. However, views defined solely for security purposes can clog the structure of an otherwise simple database. For this reason, some DBMS brands allow a column list for the SELECT privilege. For example, the following GRANT statement is legal for the Sybase, SQL Server, and Informix DBMS brands: Give accounts receivable users read-only access to the employee number, name, and sales office columns of the SALESREPS table.
GRANT SELECT (EMPL_NUM, NAME, REP_OFFICE) ON SALESREPS TO ARUSER
This GRANT statement eliminates the need for the REPINFO view defined in Figure 15-3, and in practice, it can eliminate the need for many views in a production database. However, the use of a column list for the SELECT privilege is unique to certain SQL dialects, and it is not permitted by the ANSI/ISO standard or by the IBM SQL products.

Passing Privileges (GRANT OPTION)
When you create a database object and become its owner, you are the only person who can grant privileges to use the object. When you grant privileges to other users, they are allowed to use the object, but they cannot pass those privileges on to other users. In this way, the owner of an object maintains very tight control both over who has permission to use the object and over which forms of access are allowed. Occasionally, you may want to allow other users to grant privileges on an object that you own. For example, consider again the EASTREPS and WESTREPS views in the sample database. Sam Clark, the vice president of sales, created these views and owns them. He can give the Los Angeles office manager, Larry Fitch, permission to use the WESTREPS view with this GRANT statement:
