Getting the current system date and time SELECT SYSDATETIME()Į.
#GET TUPLES THAT STARTED FROM CERTAIN DATE UP IN SQL 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) Also, what you are calling your 'tuple' is actually a Python dictionary, but that isn't a problem. Getting the current system time SELECT CONVERT (time, SYSDATETIME()) Generally speaking, you need a string to be executed that contains placeholders to accept the values contained within the tuple. Getting the current system date SELECT CONVERT (date, SYSDATETIME())Ĭ. MM represents a two-digit month e.g., 01, 02, and 12. SYSDATETIMEOFFSET() 13:10:02.0474381 -07:00ī. 3) MySQL INSERT Inserting dates into the table example YYYY represents a four-digit year e.g., 2018. 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. Normally, to send multiple records, several calls would be used to set the create statement, get each record, and then the exit flag. 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. SYSDATETIME and SYSUTCDATETIME have more fractional seconds precision than GETDATE and GETUTCDATE.
