   • CONVERT Date INT to DATE in SQL

     Top Answer

     Answered Jul 17, 2023 · 5 votes

     (Read below for my answer for if it's an int column)

     Assuming it's a textual string:

     Assuming that datadate is a string (character, text, etc) column and not a date/datetime/datetime2/datetimeoffset column, then use the CONVERT function with style: 23. The 23 value corresponds to ISO 8601 because the values are in yyyy-MM-dd-order, even though they're missing dashes.

     This page has a reference of style numbers: https://learn.microsoft.com/en-us/sql/t-sql/functions/cast-and-convert-transact-sql?view=sql-server-ver15

     SELECT *FROM ( SELECT myTable.* CONVERT( date, datadate, 23 ) AS valueAsDate FROM myTable ) AS qWHERE q.valueAsDate = DATEADD( dd, -1, GETDATE() )-

     The quick-and-dirty way is to convert the int to varchar and then use the same code as above as if it were a textual field - but don't do this because it's slow:

     SELECT *FROM ( SELECT myTable.*, CONVERT( char(8), datadate ) AS valueAsChar, CONVERT( date, CONVERT( char(8), datadate ), 23 ) AS valueAsDate FROM myTable ) AS qWHERE q.valueAsDate = DATEADD( dd, -1, GETDATE() )-

     (I extend my gratitude to @alain for pointing out a rather egregious error in my arithmetic and providing a better solution)

     We'll need to use DATEFROMPARTS and extract each component using Base-10 arithmetic (fun)!

     Supposing we have an integer representing a formatted date (the horror) such as 20200531 then we need to use integer-only arithmetic, such that division truncates rather than rounds - so dividing by 10000, we get 2020, then multiply back to get 20200000:

     20200531 / 10000 => 2020 2020 * 10000 => 2020000020200531 - 20200000 => 531 531 / 100 => 5 5 * 100 => 500 531 - 500 => 31-

     Or:

     datadate / 10000 => yyyy yyyy * 10000 => yyyy0000datadate - yyyy0000 => MMdd MMdd / 100 => MM MM * 100 => MM00 MMdd - MM00 => dd-

     ...which reduces down to:

     yyyy = ( datadate / 10000 ) MM = ( datadate - ( yyyy * 10000 ) ) / 100 dd = ( ( datadate - ( yyyy * 10000 ) ) - ( ( MM ) * 100 ) )-

     ...which can be converted into a T-SQL scalar UDF:

     CREATE FUNCTION dbo.UnhorriblifyDate( @date int )RETURNS date WITH SCHEMABINDING, RETURNS NULL ON NULL INPUT, INLINE = ONASBEGIN- DECLARE @yyyy int = @date / 10000; DECLARE @mm int = ( @date - ( @yyyy * 10000 ) ) / 100; DECLARE @dd int = ( ( @date - ( @yyyy * 10000 ) ) - ( ( @mm ) * 100 ) ); DECLARE @result date = DATEFROMPARTS( @yyyy, @mm, @dd ); RETURN @result;END-

     Or in a query:

     WITH dateParts AS (-SELECT c.datadata, c.yyyy, c.mm, ( ( c.datadate - ( c.yyyy * 10000 ) ) - ( ( c.MM ) * 100 ) ) AS ddFROM ( SELECT b.datadata, b.yyyy, ( b.datadate - ( b.yyyy * 10000 ) ) / 100 AS mm FROM ( SELECT a.datadata, a.datadate / 10000 AS yyyy FROM myTable AS a ) AS b ) AS c)SELECT c.datadata, DATEFROMPARTS( d.yyyy, d.mm, d.dd ) AS valueAsDateFROM dateParts AS d;-

     nullif([startdate],'NULL') returns [startdate] unless it equals to 'NULL' and then it returns NULL (a real NULL, not the string 'NULL')

     INSERT INTO Destination_Table [new_date] SELECT CONVERT(DATE,nullif([startdate],'NULL'),103) from Source_Table-

   • convert date to spanish in sql

     Top Answer

     Answered May 23, 2013 · 2 votes

     Maybe is cumbersome, but I don't see how to do it on an easier way.

     First, create a function. This function will make use of system view sys.syslanguages to get the correct name of month in spanish. Parameters are a valid date and language (alias on sys.syslanguage view).

     CREATE FUNCTION [dbo].[fn_GetMonthName] ( @Date DATETIME, @Language NVARCHAR(100))RETURNS NVARCHAR(400)ASBEGIN DECLARE @i INT, @m INT,@mlist NVARCHAR(1000) SET @m = MONTH(@Date) SET @mlist = (SELECT months FROM sys.syslanguages WHERE ALIAS = @language) SET @i = 1 WHILE(@i < @m) BEGIN SET @mlist = REPLACE(@mlist, SUBSTRING(@mlist,1,CHARINDEX(',',@mlist)) ,'') SET @i = @i + 1 END SET @mlist = (CASE CHARINDEX(',',@mlist) WHEN 0 THEN @mlist ELSE SUBSTRING(@mlist,0,CHARINDEX(',',@mlist) ) END ) RETURN @mlistENDGO

     Then call the function anywhere you need to:

     SELECT CONVERT(VARCHAR(20), GETDATE(), 100) AS CurrentDate, dbo.fn_GetMonthName (GETDATE(), 'Spanish') AS [Mes-Month]

     Result:

     CurrentDate Mes-Month May 24 2013 12:02AM Mayo
