The current language setting determines the default date format. For example, if the two-digit year cutoff is the default 2049, the two-digit year 49 is interpreted as 2049 and the two-digit year 50 is interpreted as 1950. ![]() A two-digit year greater than the last two digits of the cutoff year is in the century that comes before the cutoff year. Note: For Informatica, yyyy is limited to the range 1582 to 9999.Ī two-digit year that is less than or equal to the last two digits of the cutoff year is in the same century as the cutoff year. To specify an integer from 0001 to 9999 that represents the cutoff year for interpreting two-digit years as four-digit years, use the Two digit year cutoff server configuration option. Only four-digit or two-digit years are supported. M, dd, and yy represent month, day, and year in a string with slash marks ( /), hyphens ( -), or periods (. The following tables show the valid string literal formats for the date data type. ![]() Supported string literal formats for date This value is used for the appended date part for implicit conversion from time to datetime2 or datetimeoffset. MM is two digits from 01 to 12 that represent a month in the specified year.ĭd is two digits from 01 to 31, depending on the month, which represents a day of the specified month. Informatica limits yyyy to the range 1582 to 9999. Yyyy is four digits from 0001 to 9999 that represent a year. January 1, 1 CE (Common Era) through DecemCE (OctoCE through DecemCE for Informatica) date description Propertyįor more information, see the Backward compatibility for down-level clients section. The date data type was introduced in SQL Server 2008 (10.0.x). See How to Format the Date & Time in SQL Server and How the FORMAT() Function Works in SQL Server for examples of how this function works.Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW) SQL analytics endpoint in Microsoft Fabric Warehouse in Microsoft Fabricĭefines a date in SQL Server. This function returns its result as a string, so if we want to further convert it to an integer, we can use the above method for converting the output from FORMAT() to an int type. Integer int 4 10 0 Convert using the FORMAT() FunctionĪs mentioned, we can also use the FORMAT() function to convert dates to another format. Result: Column Name system_type_name max_length precision scale We can verify this by running the query through the sys.dm_exec_describe_first_result_set() function: SELECTįROM sys.dm_exec_describe_first_result_set(ĬONVERT( int, CONVERT( nchar(8), 112 ) ) AS Integer ', ![]() If we want to convert the date to an integer in the yyyymmdd format, we can take the above result, and convert it to an integer.ĬONVERT( int, CONVERT( nchar(8), 112 ) ) AS Integer Įven though the output looks the same, the left column is a string and the right column is an integer. That’s all we need to do in order to convert the date to a string in the yyyymmdd format. The value of 112 is used to format the result as yyyymmdd. In this case I used CONVERT() to convert the number to an nchar(8), and I used 112 to determine the format of the resulting string. Here’s an example of converting the date value to a string in yyyymmdd format: DECLARE date = '' In SQL Server, the date type expresses dates in the yyyy-mm-dd format, but we can use the following technique to remove the delimiters and express the date as yyyymmdd. This format adheres to the ISO 8601 standard, which defines dates to be written as yyyymmdd, or when using delimiters, as yyyy-mm-dd. In SQL Server, we can use functions like CONVERT() or FORMAT() to convert a valid date type into a format like yyyymmdd.
