SQL UNIQUE Constraint
The UNIQUE constraint ensures that all values in a column are different.
Having either all columns or a single column returned back has limited utility. 1:33 Remember, the power of SQL is that you can retrieve any subset of information 1:38. Lines 97-98 set rngSrc, the column of data from our Source Worksheet. Since we know the column number (lngIdx, as we're looping through the columns) as well as the last-occupied row on the Source Worksheet (lngLastSrcRowNum), we can create this Range using these cells.

The list contains large amount of text in a column and it would be nice to display the first 5 lines of text followed by a Read more link. I've seen examples of this for Sharepoint 2010 but not for.

Both the UNIQUE and PRIMARY KEY constraints provide a guarantee for uniqueness for a column or set of columns.
A PRIMARY KEY constraint automatically has a UNIQUE constraint.
However, you can have many UNIQUE constraints per table, but only one PRIMARY KEY constraint per table.
SQL UNIQUE Constraint on CREATE TABLE
The following SQL creates a UNIQUE constraint on the 'ID' column when the 'Persons' table is created:
SQL Server / Oracle / MS Access:
ID int NOT NULL UNIQUE,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int
);
MySQL:
ID int NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int,
UNIQUE (ID)
);
To name a UNIQUE constraint, and to define a UNIQUE constraint on multiple columns, use the following SQL syntax:
MySQL / SQL Server / Oracle / MS Access:
ID int NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int,
CONSTRAINT UC_Person UNIQUE (ID,LastName)
);
SQL UNIQUE Constraint on ALTER TABLE
To create a UNIQUE constraint on the 'ID' column when the table is already created, use the following SQL:
MySQL / SQL Server / Oracle / MS Access:
To name a UNIQUE constraint, and to define a UNIQUE constraint on multiple columns, use the following SQL syntax:
MySQL / SQL Server / Oracle / MS Access:
ADD CONSTRAINT UC_Person UNIQUE (ID,LastName);
DROP a UNIQUE Constraint
To drop a UNIQUE constraint, use the following SQL:

Or is it the NCAA that is changing important sports traditions by loosening to the point of elimination its rules limiting transfers of college athletes from one school to another? March 22nd 1st payment bill.
Or is it state action, like that of California and its law that will permit college athletes to earn money by endorsing products or selling their images?
Two related North Carolina-connected books deal with the complicated pluses and minuses of college sports: 'Marching Toward Madness: How to Save the Games You Always Loved' by John LeBar and Allen Paul, and 'Larry Miller Time: The Story of the Lost Legend Who Sparked the Tar Heel Dynasty' by Stephen Demorest.
In 'Marching Toward Madness,' LeBar and Paul argue that college athletics are threatened, but they see it a different way.
'Impelled by runaway spending and rampant corruption, America's much-beloved games of college basketball and football have not been so threatened since the widespread cheating scandals in the early 1950s. The specter of billion-dollar sums being showered on imperial coaches, voracious athletic directors, hordes of support staff, and lavish comforts for fat-cat fans has led to a near-deafening roar to pay the players. The injustice of such sums being amassed, in the main, from the labor of young men of color — many of whom come from disadvantaged backgrounds — cannot be justified.'
They cite multiple reasons why paying college athletes would be a mistake and present 'comprehensive reforms to end cheating and corruption in college sports, put academics first, and end the peonage of non-white athletes once and for all.'
Their proposals are aimed at preserving or restoring the scholar-athlete image and tradition that provided students with the benefits of a serious educational experience together with athletics that are an important factor, but not a dominating one.
They illustrate this ideal with numerous examples from LeBar's experience as a tennis coach at Duke. He tells about some of his players who were 'collegiate sports heroes who had brawn and brains, athletes who ran with blazing speed and applied gray matter just as fast.'
In 'Larry Miller Time,' Demorest tells the story of one of the greatest of the great Carolina Tar Heel basketball players of all time. Playing for Coach Dean Smith in the 1960s, he helped create the coach's legend by winning his first two ACC titles and an appearance in the NCAA national championship game. Miller was a two-time All American and was twice named ACC player of the Year.
Miller grew up in Pennsylvania and was a record-setting and heavily recruited high school player. Duke and Carolina were contenders. Miller apparently found out that Duke basketball players came to Chapel Hill to party. Being a party loving young man, he chose to be in Chapel Hill full time.
Women loved Miller, and he loved them back. One of those women who swooned over him was a young girl named Nancy Curlee. Years later, long after she had married Demorest, they were driving near Catasauqua, Pennsylvania, where Miller was living. Nancy insisted they drop by Miller's house. They found him working in his garden, built a friendship, and the new book is the result.
Both Nancy and Stephen, who live in Hillsborough, are experienced writers who created content for television programs such as 'The Guiding Light.' Stephen uses those story-telling gifts to tell Miller's tales of competition, fun-loving partying, great success, near tragedy, a disappointing conclusion to his professional career, and many years living out of the bright lights until Nancy and Stephen dropped by for a visit.
