PL/SQL does have a boolean data type, so if you’rewriting PL/SQL code(a stored procedure, for example), you can use the boolean data type. SQL Server Boolean There isno boolean data typein SQL Server. However,

publicstructSqlBoolean : IComparable, IEquatable<System.Data.SqlTypes.SqlBoolean>, System.Data.SqlTypes.INullable, System.Xml.Serialization.IXmlSerializable 继承 Object ValueType SqlBoolean 注解 任何非零值都解释为 1。 SqlBoolean结构和标准布尔值之间的主要区别在于,如果标准布尔值有两个可能的值,true和fals...
Boolean data type The Boolean data type represents the values of true, false, and unknown. Boolean constants TRUE, FALSE, and UNKNOWN represent the corresponding Boolean truth values. ON and OFF are synonyms for TRUE and FALSE. UNKNOWN is identical to the NULL constant. When performing comparison...
繼承 Object ValueType SqlBoolean 實作 INullable IComparable IXmlSerializable IEquatable<SqlBoolean> 備註任何非零值會解譯為 1。SqlBoolean 結構和標準布爾值之間的主要差異在於,其中標準布爾值有兩個可能值,true 和false,SqlBoolean 結構有三個可能的值:True、False或Null。

Yes, it's correct. the data type of the Boolean data in SQL Server is bit data type, and it could store 1,0 and NULL. Also, the string values TRUE and FALSE could be converted to bit values, which is mentioned at/en-us/sql/t-sql/data-types/bit-transact-sql?view=sql-server-201...
I need to insert a Boolean value into an SQL Server datatable. I'm having a problem with what I'm trying. I don't see the option for a Boolean data type in SQL Server so I used Binary(1). Is this the right data type for storing Boolean in SQL Server? The lines: cmd.Parameters...
To facilitate the use of code written for SQL implementations from other vendors, MySQL maps data types as shown in the following table. These mappings make it easier to import table definitions from other database systems into MySQL. Data type mapping occurs at table creation time, after which...
