![]() 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 only difference is that the CURDATE() is a standard MySQL function and is supported by all the versions of MySQL whereas CURRENT_DATE() is supported by the versions MySQL 4.0 and earlier.SYSDATETIME and SYSUTCDATETIME have more fractional seconds precision than GETDATE and GETUTCDATE. The CURDATE() and CURRENT_DATE() are synonyms of each other and have the same functionality. It can be used with the WHERE clause and for selecting or updating a query as well.īut, you must have come across other terms in MySQL such as CURRENT_DATE, CURRENT_DATE() along with CURDATE() functions. Alternatively, we can use it to calculate age based on a person's date of birth. For instance, it can be used in places where we need to show the days countdown from the server side. MySQL's current date has several applications in various scenarios. Since the function is only conformed to yield the current date as the value, it will extract the current date and returns it in the YYYY-MM-DD format by default. The MySQL CURDATE() function will fetch the current date and time from the system clock of the MySQL server. How does the MySQL CURDATE() Function Work? If we are also concerned about the format of the value returned, the DATE_FORMAT can also be used along with this function. The correct alternative is to use DATE_ADD() or DATE_SUB() to perform any arithmetic operations on a date. However, the CURDATE() function might give you an incorrect output when you're trying to add/subtract a numeric value (that exceeds the current month's limit) to/from it. It's important to know the fact that it returns the value based on the timezone of the MySQL server. The MySQL current date has no exceptions to consider as it is a simple function. We'll see its uses in the examples section. NOTE: The second approach can also be used to fetch any other date concerning the numeric value used here.
