#CONVERT BINARY COLUMN TO STRING PSEQUEL CODE#
Use CAST instead of CONVERT if you want Transact-SQL program code to comply with ISO. For example, the following CAST function converts the numeric value of $157.27 into a character string of '157.27': CAST ( $157.27 AS VARCHAR(10) ) The CAST and CONVERT functions convert a value (a local variable, a column, or another expression) from one data type to another. SYSDATETIME() implicitly converts to date style 21.Įxplicit conversions use the CAST or CONVERT functions. GETDATE() implicitly converts to date style 0. For example, when a smallint is compared to an int, the smallint is implicitly converted to int before the comparison proceeds.
SQL Server automatically converts the data from one data type to another. Implicit conversions are not visible to the user. Implicit and explicit conversionĭata types can be converted either implicitly or explicitly. When you convert between an application variable and a SQL Server result set column, return code, parameter, or parameter marker, the supported data type conversions are defined by the database API. When data from a Transact-SQL result column, return code, or output parameter is moved into a program variable, the data must be converted from the SQL Server system data type to the data type of the variable.When data from one object is moved to, compared with, or combined with data from another object, the data may have to be converted from the data type of one object to the data type of the other.Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW)ĭata types can be converted in the following scenarios:
