This uses the XML conversion functions that don't throw errors when the number won't fit ) - Create function to convert a varchar to a decimal (returns null if it fails) If you're on an earlier version then you can write a function that'll convert to a decimal (or NULL if it won't convert). The rowversion is generally used for version-stamping table rows.IsNumeric is a problem child - SQL 2012 and later has TRY_CAST and TRY_CONVERT In SQL Server timestamp is the synonym for the rowversion data type which automatically generate, unique binary numbers within a database. Valid range for time zone offset is from -14:00 to +14:00. Same as datetime2 with the addition of a time zone offset. Valid date range for smalldatetime is from (January 1, 1900) to Stores a combined date and time value with an accuracy of 1 minute. Valid date range for datetime2 is from (January 1, 1) to (December 31, 9999).
The datetime2 is an extension of the datetime data type that has a larger date range. Valid date range for datetime is from (January 1, 1753) to (December 31, 9999). Stores a combined date and time value with an accuracy of 3.33 milliseconds. Stores time of a day with the accuracy of 100 nanoseconds. Stores a date value in the range from (January 1, 1) to in the range from -9999.99 to 9999.99.ĭate and Time data types are normally used to store data like date of birth, hiring date, date and time when a record is created or updated inside table, etc. The default scale is 0.įor example, the price decimal(6,2) column can store any value with six digits and two decimals i.e. This number is subtracted from p to determine the maximum number of digits to the left of the decimal point. Whereas, the s or scale indicates the maximum number of digits that can be stored to the right of the decimal point. The precision must be a value from 1 to 38. When declaring a or decimal or numeric column, the precision and scale can be specified, like decimal( p, s) or numeric( p, s), where the p or precision indicates the maximum total number of digits that can be stored, both to the left and to the right of the decimal point. The numeric datatype is functionally equivalent to decimal.Īllows you to store monetary or currency values accurately in the range from -214,748.3648 to 214,748.3647.Īllows you to store monetary or currency values accurately in the range from -922,337,203,685,477.5808 to 922,337,203,685,477.5807. Valid values are from 10 ^38 +1 through 10 ^38 - 1. Stores fixed precision and scale numbers. Stores integer values in the range from -32,768 to 32,767. Stores integer values in the range from 0 to 255. Numeric data types are normally used to store data like price, salary etc.Īllows you to store a value 1, 0, or NULL.
