Default Format : YYYY-MM-DD hh:mm:ss.nnn.Seconds values that are 29.998 seconds or less are rounded down to the nearest minute, Values of 29.999 seconds or more are rounded up to the nearest minute. DECLARE DECIMAL(5,3)īelow were the only two Date and Time data types that were present in Sql Server prior to Sql Server 2008. DECLARE DECIMAL(4,3)Īrithmetic overflow error converting numeric to data type numeric. Working with DECIMAL data type DECLARE DECIMAL(3,3)Īrithmetic overflow error converting numeric to data type numeric. DECLARE TINYINTĪrithmetic overflow error for data type tinyint, value = -150.Īrithmetic overflow error for data type smallint, value = 40000. DECLARE BITĭEMO 2: Try to assign value other than 0, 1 and NULL DECLARE BITĬonversion failed when converting the varchar value ‘TEST’ to data type bit.ĭEMO 1: Valid Range 0 to 255 DECLARE TINYINTĭEMO 2: Try to assign out of range value for TinyInt DECLARE TINYINTĪrithmetic overflow error for data type tinyint, value = 260.
If n valueIf 1<=n<= 24, n is treated as 24, precision will be 7 digits and storage size will be 4 bytes.If 25<=n<= 53, n is treated as 53, precision will be 15 digits and storage size will be 8 bytes. If nis specified, it must be a value between 1 and 53. n is the number of bits that are used to store the mantissa of the float number in scientific notation and, therefore, dictates the precision and storage size. Example: decimal(5,2) is a number that has 3 ( p-s) digits before the decimal and 2 digits after the decimal. If there are from 9 up to 16 bit columns, the columns are stored as 2 bytes, and so on. If there are 8 or less bit columns in a table, the columns are stored as 1 byte. Let us go-through each of these categories of datatypes. Non-Unicode Character String Data Types.SELECT statement can assign values to more than one variable at a time DECLARE INT, INTįollowing are the Main categories of Data Types in Sql Server SET statement can assign only one variable at a time. DECLARE INT = 10ĭEMO 4: Variables can be assigned value by using SET/SELECT statement as shown below. PRINT 2: Multiple variables can be declared using single declare statement as shown below DECLARE INT, TINYINTĭEMO 3: Variables can be assigned value while declaring as shown below in Sql Server 2008 and above. Variables can be declared by using DECLARE statement in Sql server as shown below.ĭEMO 1: Declaring an Integer Variable, assigning value using SET statement and displaying it’s value using PRINT statement DECLARE INT Each variable in Sql Server has a specific type, which determines the size and layout of the variable’s memory the range of values that can be stored within that memory and the set of operations that can be applied to the variable. We can place data into them and retrieve. VariablesĪ variable is nothing but a name given to a storage location.
