What is BIT datatype in SQL Server?

What is BIT datatype in SQL Server?

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. Additionally, string values TRUE and FALSE can be converted to 1 and 0 corresponding to bit values.

How insert BIT data type in SQL Server?

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.

Is BIT 0 True or false?

The string values TRUE and FALSE can be converted to bit values: TRUE is converted to 1 and FALSE is converted to 0. Converting to bit promotes any nonzero value to 1.

How do I return a BIT value in SQL Server?

We need to directly return the calculated BIT value based on condition. So we use the CAST() method available in SQL. We can use the CAST method to cast from one data type to another. You might want to cast a float value to int value for that we use CAST().
