![]() ![]() Make sure to adapt the examples to your specific requirements, and be aware of any potential issues with date formats or data integrity in your database. It’s important to note that the input string must be in a format that SQL Server can recognize as a date, and the ‘YYYY-MM-DD’ format is commonly used for this purpose. You can also use the CONVERT function, which is another way to achieve the same result: - Example 2: Using CONVERT to cast a string to a DATEīoth examples achieve the same result, and you can choose the method that you find more readable or convenient. Learn how to use the CAST () and TODATE () functions to convert a string to a date in SQL. Finally, the converted date is selected and displayed. The CAST function is then used to convert this string to the DATE data type, and the result is stored in the variable. ![]() Syntax for the SQ: CONVERT () function is as follows. In this example, the variable is a string representing a date in the ‘YYYY-MM-DD’ format. We can use the SQL CONVERT () function in SQL Server to format DateTime in various formats. Here’s an example of using CAST to convert a string to a DATE in SQL Server: DECLARE NVARCHAR(10) = '' The CAST function allows you to explicitly specify the target data type and perform the conversion. When dealing with dates, it’s common to use the CAST function to convert a string or another compatible data type to the DATE data type. In this tutorial, you have learned how to use the CAST() and TO_DATE() functions to convert a string to a date in SQL.In SQL Server, the CAST function is used to convert one data type to another. ![]() Notice that the date format must be corresponding to the date string as specified in the statement DD MON YYYYĬheck it out the Oracle TO_DATE() and PostgreSQL TO_DATE() functions for the details. The following shows the TO_DATE() function syntax: TO_DATE(string, format)įor example, to convert the string '' to a date value, you use the following statement: SELECT TO_DATE( '', 'DD MON YYYY' ) Oracle and PostgreSQL provide the TO_DATE() function that converts a string to date based on a specified format. is the date and time format for the string. It can be a value of any data type CHAR, VARCHAR2, NCHAR, or NVARCHAR2. ![]() is a string value which is converted to a DATE value. The TODATE() function accepts three arguments: 1) string. Here is the result: Code language: SQL (Structured Query Language) ( sql ) Convert string to date using TO_DATE() function Applies to: Databricks SQL Databricks Runtime Casts the value expr to the target data type type. SQL Server provides a number of options you can use for formatting a date/time string in SQL queries and stored procedures either from an input file (Excel, CSV, etc.) or a date column (datetime, datetime2, smalldatetime, etc.) from a table. TODATE (string, format, nlslanguage) Code language: SQL (Structured Query Language) (sql) Arguments. For information about using the CAST and CONVERT functions with date and time data, see CAST and CONVERT (Transact-SQL). When you convert to date and time data types, SQL Server rejects all values it can't recognize as dates or times. Similarly, the following example also converts the string 180101 to January 1st, 2018: SELECT CAST( '180101' AS DATE) CAST syntax: syntaxsql CAST ( expression AS datatype ( length ) ) CONVERT syntax: syntaxsql CONVERT ( datatype ( length ), expression, style ) Transact-SQL syntax conventions Note To view Transact-SQL syntax for SQL Server 2014 (12.x) and earlier versions, see Previous versions documentation. datetime isn't ANSI or ISO 8601 compliant. SQL Server converts the string 2018 to January 1st, 2018: The following example shows how to convert a string to a date: SELECT CAST( '2018' AS DATE) In case the function fails to convert, it issues an error, depending on the implementation of a specific database system. The CAST() function returns a DATE value if it successfully converts the string to date. In this syntax, the string can be any DATE value that is convertible to a date. The following illustrates the syntax of the CAST() function: CAST (string AS DATE)Ĭode language: SQL (Structured Query Language) ( sql ) SQL provides a CAST() function that allows you to convert a string to a date. Convert string to date using CAST() function Summary: in this tutorial, you will learn various functions that convert a string to a date in SQL. ![]()
