The Transact-SQL rowversion data type is not a date or time data type. The following tables list the Transact-SQL date and time functions. See Deterministic and Nondeterministic Functions for more information about determinism. Transact-SQL derives all system date and time values from the operating system of the computer on which the instance of SQL Server runs.

SQL Server The accuracy depends on the computer hardware and version of Windows on which the instance of SQL Server running. This API has a precision fixed at nanoseconds. Skip to main content.

You might face the following issues with it. We do face many such scenarios when we do not have a date format as per our requirement. We cannot change table properties to satisfy each requirement. In this case, we need to use the built-in functions in SQL Server to give the required date format.

As highlighted earlier, we might need to format a date in different formats as per our requirements. We can see various date formats in the following table. You can keep this table handy for reference purpose in the format of Date Time columns. Datetime format in YY. Datetime format in [YYYY. Datetime format in DD. YY format Standard : German. This example is approximately the opposite of the previous example. This example shows that Style 1 can force result truncation.

The characters 0x in the result set force the truncation. This example shows that Style 2 does not truncate the result, because the result does not include the characters 0x. The following example defines a variable of type VARCHAR, assigns an integer value to the variable, then selects a concatenation of the variable with a string.

If we provide a string that can be converted, the statement will succeed, as seen in the following example:. In this case, the string '1' can be converted to the integer value 1, so this SELECT statement will return the value 2. This example retrieves the name of the product for those products that have a 3 in the first digit of their list price, and converts the ListPrice of these products to int.

This example calculates a single column value by dividing the product unit price UnitPrice by the discount percentage UnitPriceDiscountPct. This result is then rounded to the nearest whole number, and finally converted to an int data type.

This example uses the AdventureWorksDW database. This example converts the money column ListPrice to an int type, and then to a char 20 type, so that the LIKE clause can use it. This example is the rough opposite of the previous example. Skip to main content. This browser is no longer supported.

Note Because Unicode data always uses an even number of bytes, use caution when you convert binary or varbinary to or from Unicode supported data types.

Warning Do not construct binary values, and then convert them to a data type of the numeric data type category. In this article. For example, the value 'T Always 17 digits. Use for lossless conversion. With this style, every distinct float or real value is guaranteed to convert to a distinct character string.

No commas every three digits to the left of the decimal point, and two digits to the right of the decimal point Example: Commas every three digits to the left of the decimal point, and two digits to the right of the decimal point Example: 3, No commas every three digits to the left of the decimal point, and four digits to the right of the decimal point Example: Use default parsing behavior that discards insignificant white space, and does not allow for an internal DTD subset.

Preserve insignificant white space. Enable limited internal DTD subset processing. If enabled, the server can use the following information that is provided in an internal DTD subset, to perform nonvalidating parse operations. Also, it does not evaluate the XML declaration to see whether the standalone attribute has a yes or no value.

Instead, it parses the XML instance as a stand-alone document. Each character or byte is converted The expression must have an even number of hexadecimal digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, a, b, c, d, e, f. If the style is set to 1, the expression must have 0x as the first two characters.
