Using Boolean in SQL Server To store Boolean values, we can use a BIT data type. A bit type is used to store values from 1 t0 64. Hence, we can use a bit value of 0 to represent false and 1 to describe true. Consider the example query below that creates a table with a Boolean...
In this article, we showed how to use this bit variable as a variable in a SQL query. We also show how to convert bit data to integer and string and finally, we teach how to use the query inside a stored procedure. If you have more questions about this SQL Boolean data type do ...
