    Dear all,

    I have updating the table(1.4 mill rows) with UPDATE query only for one column,

    but the table has locked and we cant acces the table from out side of Query analyzer , what will be the problem...? is any problem in table structures..

    Example

    Update table set column1 = column2

    You're updating the entire table, hence the entire table will be locked for the duration of the update statement.
