    The data type bit can only contain numeric 0 and 1; "false"/"true" are strings, that's not possible. You have to convert it like

    SELECT CASE WHEN value = 'false' THEN 0 ELSE 1 END AS BitValue

    SQL Server actually supports implicit conversion of the strings 'true' and 'false' to 1 and 0:

    CREATE TABLE #bit(b bit NULL)
go
INSERT #bit(b) VALUES('true'), ('false')
go
SELECT b FROM #bit
