Date setdate update#
Getting the current system date SELECT CONVERT (date, SYSDATETIME())į. If the dayValue is outside of the range of date values for the month, setDate () will update the Date object accordingly. Getting the current system date and time SELECT SYSDATETIME()Į.
Date setdate series#
The values are returned in series therefore, their fractional seconds might be different. The following examples use the three SQL Server system functions that return current date and time to return the date, time, or both. SYSDATETIME() 13:18:45.3490361Įxamples: Azure Synapse Analytics and Analytics Platform System (PDW) Getting the current system time SELECT CONVERT (time, SYSDATETIME()) Getting the current system date SELECT CONVERT (date, SYSDATETIME())Ĭ. Getting the current system date and time SELECT SYSDATETIME() The following examples use the six SQL Server system functions that return current date and time to return the date, time, or both. DECLARE datetimeoffset = switchoffset (CONVERT(datetimeoffset, GETDATE()), '-04:00') The optimizer will then have accurate cardinality estimates for GETDATE() and will produce a more efficient query plan. In addition, use the OPTION (RECOMPILE) query hint to force the query optimizer to recompile a query plan the next time the same query is executed. We recommend that you precompute the GETDATE value and then specify that value in the query as shown in the following example. Using SWITCHOFFSET with the function GETDATE() can cause the query to run slowly because the query optimizer is unable to obtain accurate cardinality estimates for the GETDATE value.
Views and expressions that reference this function in a column cannot be indexed. Transact-SQL statements can refer to GETDATE anywhere they can refer to a datetime expression. Transact-SQL Syntax Conventions Syntax GETDATE() Use AT TIME ZONE in Azure SQL Database or Azure Synapse Analytics if you need to interpret date and time information in a non-UTC time zone.įor an overview of all Transact-SQL date and time data types and functions, see Date and Time Data Types and Functions (Transact-SQL). SYSDATETIME, SYSUTCDATETIME, and SYSDATETIMEOFFSET can be assigned to a variable of any of the date and time types.Īzure SQL Database (with the exception of Azure SQL Managed Instance) and Azure Synapse Analytics follow UTC. SYSDATETIMEOFFSET includes the system time zone offset.
The definition of '' in that specification. Examples Using setDate() var theBigDay = new Date(1962, 6, 7) // (7th of July 1962)
1 would result in the date being set to 1 day before the last day of the previous month. If a negative number is provided for dayValue, the date will be set counting backwards from the last day of the previous month. If the dayValue is outside of the range of date values for the month, setDate() will update the Date object accordingly.įor example, if 0 is provided for dayValue, the date will be set to the last day of the previous month. The number of milliseconds between 1 January 1970 00:00:00 UTC and the given date (the Date object is also changed in place). Syntax tDate( dayValue) Parameters dayValue An integer representing the day of the month. If you'd like to contribute to the interactive examples project, please clone and send us a pull request.
