I am trying to insert or edit the bit value to "0" or "1", but either returns me a blank.
Could someone tells me how to insert the value in it?
Also, Is that possible to not use bit type but Boolean? I see there's a Boolean type in the list of types
Thanks
Hi, I have uploaded the picture, the cell in the table is blank, but I have tried several times, add, update, all take effect, but cell keeps blank...

To insert a new value to the BIT column, use INSERT statement: INSERT INTO table_name (bit_column) VALUES (1); You can also use TRUE and FALSE as the inputs for the BIT columns, SQL Server will automatically convert them as follow: TRUE will be converted to 1.
A bit is a binary digit, the smallest increment of data on a computer. A bit can hold only one of two values: 0 or 1, corresponding to the electrical values of off or on, respectively.
SQL Server bit data type is an integer data type that can take only one of these values: 0, 1, NULL. With regard to the storage, if there are less than 9 columns of the bit data in the table, they are stored as 1 byte. If there are 9 to 16 such columns, they consume 2 bytes and so on.
bit columns hold either 0 or 1. Integer values other than 0 or 1 are accepted, but are always interpreted as 1. Storage size is 1 byte. Multiple bit datatypes in a table are collected into bytes. For example, 7 bit columns fit into 1 byte; 9 bit columns take 2 bytes.
Generally speaking, for boolean or bit data types, you would use 0 or 1 like so:
UPDATE tbl SET bitCol = 1 WHERE bitCol = 0 See also:
